Q: What is precision plastic?
A: Precision plastics and injection molding are the ideal solutions for these facilities. They help create more sanitary and efficient waste treatment processes. Common precision plastic parts in this field include wear pads, seals, rollers, valves, connectors, brushings, drainage units, catch basins, and much more.
Q: What is DFM in mould design?
A: Design for Manufacturing (DFM) describes the process of designing or engineering a product to reduce its manufacturing costs, allowing potential problems to be fixed in the design phase which is the least expensive place to address them.
Q: What is the difference between CNC and mold?
A: CNC machining is a subtractive manufacturing process that uses metal cutters to remove material from a workpiece to create the final part shape. Plastic injection molding forces liquid plastic to conform to the shape of a mold to make the finished part.
Q: What is precision injection Moulding?
A: Precision injection is a method of injection molding that requires great accuracy. It is not used to produce an entire product, but instead for rare occasions when a project requires a precise form of plastic injection molding.
Q: What plastic is best for precision machining?
A: Acetal, PEEK and PVC plastic materials have superior machining characteristics, plus they resist melting and chipping while offering good dimensional stability.
Q: How were molds made before CNC?
A: Earlier, there were many manually operated high precision Lathes, Milling, Grinding and Jig boring Machines etc. Extremely skilled operators used to operate these machines to create parts of high dimensional and form accuracies.
Q: Is CNC better than forged?
A: Generally, CNC machining is less expensive than forging, though it is most cost-efficient when making small batches of complex parts. But due to forging's ability to make stronger components, forging may be more cost-efficient in the long run if your project requires durable and long-lasting parts.
Q: What is CNC in plastic?
A: Plastic CNC Machining is a CNC machining process that uses Computer Numerical Control (CNC) technology to automate machining of plastic materials. This is achieved through computer programming guiding the machine tools.
Q: What is the function of precision commodity molds?
A: The function of precision commodity molds is to produce high-quality and accurate molds for various consumer products, such as plastic bottles, containers, and other household items. These molds are designed with precision and accuracy to ensure that the final product is consistent, with excellent surface finish, precise dimensions, and minimal defects.
Q: What are the classifications of precision commodity molds?
A: Precision commodity molds can be classified based on the type of commodity they are used for, such as automotive parts, medical devices, consumer goods, and packaging. They can also be classified based on the manufacturing process they are designed for, such as injection molding, blow molding, or thermoforming.
Q: Why do we need to use precision commodity molds?
A: We need to use precision commodity molds because they ensure consistency and accuracy in the manufacturing process. Precision molds can produce high-quality and uniform commodities with minimal defects, resulting in increased efficiency, reduced waste, and reduced costs. Precision molds can also help to avoid problems such as warping, cracking, and uneven surfaces, which can compromise the durability and usability of the final product.
Q: What are the advantages of mould?
A: Some molds perform valuable functions in our lives. For example, they age and flavor cheeses and they are used in bread making, fermenting liquor, producing soy sauce, producing penicillin and manufacturing citric acid used to flavor soft drinks.
Q: What are the advantages of molding?
A: One of the main benefits of plastic injection molding is its high repeatability. Once you've created your mold, you can produce thousands of parts before needing to maintain your tooling.
Q: What is the importance of mold in industry?
A: Molds cause biodegradation of natural materials, which can be unwanted when it becomes food spoilage or damage to property. They also play important roles in biotechnology and food science in the production of various pigments, foods, beverages, antibiotics, pharmaceuticals and enzymes.
Q: What is the importance of molding process?
A: Molding processes are the major periodic manufacturing operations in the polymer industry. An enormous amount of plastic, rubber, and thermoset parts, ranging from automobile bumpers to personal computers, refrigerator housings to bottles and tires, are produced by molding processes.
Q: What is the purpose of molding?
A: Primarily, molding serves three functions: it adds decoration to a room, covers gaps between the walls and ceiling or floor and it protects wall surfaces. Molding is available in lengths up to 16 feet (Most lumberyards stock these lengths, but hardware stores and home centers may not.) and in a variety of shapes.
Q: What is precision Moulding?
A: This is when CNC machining is used to mold the plastics into precise and calculated shapes. The machines have high pressure that helps improve the quality and precision of the plastic parts. They also manage to repeatedly create an accurate product.
Q: What is precision fabrication?
A: A precision metal fabricator cuts, bends, forms and assembles precise metal parts. Like piecing together a puzzle, the fabricator produces specialized components at very high tolerances, for products such as medical devices and aerospace parts.
Q: What are the 4 stages of injection moulding?
A: The individual parts of this process are very short. The whole injection moulding process usual lasts from 2 seconds to 2 minutes. There are four stages in the cycle. These stages are the clamping, injection, cooling and ejection stages.

China provides many long-term advantages as an operating location to produce your specialty injection molding products. China saw demand increase 1.470 million tons from 2020 – 6.0% year-on-year growth! By 2022 it’s expected to have reached 26.91 million tons! When searching for molding suppliers or manufacturers in China it is essential that some key points be considered:
At first, your goal should be to find an outstanding provider who offers competitive prices and quick products; but don’t stop there; look also for those that meet quality standards as well as those offering after-sale support services.
Quality should be an indispensable characteristic when looking for a supplier. You need to be confident they will produce top-grade goods, with warranties covering those goods so you won’t have to worry about getting bad parts or defective molds from their product line.
Make sure they can deliver on time so your production schedule won’t be disturbed, and look for companies with excellent reputations; someone who has been doing business long enough and fulfilled on their promises should give you assurances of reliability.
Your ideal supplier must possess an in-depth knowledge of their industry. Not only should they create high-quality products, but they should understand both consumer tastes and market dynamics to develop products which appeal directly to them. This way they are sure to produce items which satisfy them both as customers.
If you need help in selecting a reliable molding supplier, do some online research or speak to other businesses within your industry about their experiences with different suppliers. When finding one suitable to you, be sure they have experience producing plastic parts tailored specifically for your industry or product, providing references from satisfied past clients who worked together successfully (like yourself!). This way you’ll avoid potential scammers!
Once your supplier and agreement are in place, delivery time has arrived! Air freight shipping offers fast and efficient transport without long waits at ports or airports that could derail production schedules.
With the continuous improvement of mold manufacturing and mold workers’ skill in China, more and more European and American companies have dropped their purchase orders to Chinese plastic mold factories.
The continuous deepening of information exchanges between the two sides has greatly promoted China’s mold industry development.
It is simple to deal with China’s mold and injection molding suppliers for those buyers who often purchase in China.
But for those who first came into contact with this mold industry, it was a very troublesome thing, especially in dealing with China’s mold factories outside of thousands of miles.
Language and technical communication constitute two significant obstacles.
Many people who bought customized plastic parts in China for the first time were completely unfamiliar with this industry.
Also, this industry is technology-intensive. The quotation requires suppliers and buyers to have a strong and wonderful interaction.
The most DECISIVE is how the buyers express their ideas to the suppliers.
It is precisely at this point that many buyers do not know how to handle it.
They often ask the supplier for a price from the VERY beginning.
In fact, the price given by the supplier at this stage is very inaccurate.
I will introduce the preparation process before the quotation of molds and molded parts so that buyers can have a clear understanding.
The manufacture of injection-molded parts is a very complicated process.
The first is the manufacture of molds, followed by injection molding, and the second operation of injection-molded parts, which involves transferring a lot of information.
The top priority is how the buyer expresses his product requirements clearly to the supplier.
In many cases, suppliers are required to quote only in the case of a hand-drawn drawing. Sometimes there is no requirement for plastic materials.
For more auto parts mould quotesinformation, please contact us. We will provide professional answers.
Buyers just mentioned adjectives like “SOFT “and “HARD” to describe the stuff he wants.
In fact, this is NOT correct.
The side location difference above will lead to total different mould cost, 1. side hole high cost,2 and 3 location holes are better.
The process of getting a plastic mold quotation is not simple, but if done correctly. The process can work the way you intended it to.
Finding an injection molding engineer or mold engineer nearby to consult is the ideal way forward, as they’ll assist with understanding how to reverse engineer parts as well as offer advice about the most efficient ways of approaching problems. You might also benefit from working with experienced plastic part producers so you don’t run into issues regarding copyrights and patents.
An early investment will pay dividends later.
Sure, it would be my honor to provide this service, yet at present it’s difficult for me to quote you accordingly.
Your first step should be finding an engineer with extensive experience, who you can talk directly with about what requirements there are for the product, its quantity requirements and assembly needs, your budget constraints and why you want the lowest possible cost product price.
Find a manufacturer that will give you samples or prototypes so you can see exactly how the finished product looks and is manufactured; this way there will be no surprises when your order arrives at your door!
By being upfront with them about what your situation entails and communicating what needs are present, they should offer valuable advice based on experience with similar products that could assist them in making informed choices that could take you in the direction you require.
At this stage, he will advise which plastic material you should select, how to design the product and assemble it as well as arrange an acceptable quantity. In addition, he can give an estimate as to cost and timeline.
At this stage, it’s wise to discuss your budget so he or she can determine whether working together is feasible for both of you. Once all aspects have been agreed upon, production will start.
Realizing a product design requires translating concepts into tangible forms. Computer-aided design (CAD) software plays a vital role in materializing ideas digitally before physical fabrication. This 3D rendering provides the foundation for manufacturing by supplying detailed specifications that instruct the creation of production molds.
CAD models enable flexibility too. Engineers can adjust the digital blueprint to accommodate tweaks from prototype feedback before tooling setup for mass production. Clear communication with design teams is crucial for capturing requirements accurately in the 3D model. The more precise the inputs, the closer the end result will match the original vision.
With an approved virtual prototype, the first physical manifestations can be 3D printed or CNC machined for hands-on testing. Prototyping identifies enhancements needed while volumes are low. Refining the product at this stage is far simpler than attempting changes mid-production.
Rapid prototyping through 3D printing enables iterative design refinement before full production. This process allows designers to evaluate aesthetics, part fit, and structural integrity of a 3D model hands-on.
If issues arise, the digital model can be quickly modified and new print samples generated for testing. Repeating rapid prototyping in this way lets designers refine the product virtually until all requirements are met.
The relatively low cost and fast turnaround of small 3D print runs makes trial-and-error refinement affordable. This upfront investment curtails expensive mold reworking later in production. For instance, small 3D printing in China may cost around $50-60 USD per iteration. Catching design flaws early on can ultimately save thousands in production line changes down the road.
Rapid prototyping compresses the design timeline by merging virtual modeling and physical testing. The instant tangible feedback 3D printing provides allows designers to spot flaws missed on screen. Rapid iteration enables optimizing the product digitally before large-scale manufacturing is underway. The savings in time and costs make rapid prototyping a worthwhile step in any development process.
After this stage, you can give your potential suppliers a chance to quote the changed design. My article on this topic is very detailed about how to deal with Chinese suppliers.
Of course, if you want to copy existing products at this stage, you can send the product directly to the supplier and tell them your specific requirements. Fees can be deducted after the transaction.
If you have only one sample and inconvenient to send it, you can take a picture of the sample.
According to the three-view standard, you show suppliers a sample photo.
Mark the position and size of the undercut, dents, and holes in each direction on the picture.
In the photo, the size of the product is identified in detail, i.e., the length, width, and height. In theory, the six sides of the product must be photographed. The more detailed photograph is, the better it is.
Don’t be afraid to imitate something that already exists, it is often the best way to learn and to create something of your own in the process.
Finding a winning product requires skill. You need to strike a balance between something trendy and one with enough earning potential that it makes financial sense for you to copy/sell as your own product or service.
Studies of your competitors can give a valuable glimpse of their activities, helping to give an indication of who and what lies ahead for your own venture. If a competitor’s product has proven popular with customers and you wish to replicate its sales success, studying how their competitor did this might give insight into how you should go about doing the same thing yourself.
But if your competitors’ products don’t line up with what you intend to accomplish with yours, this won’t provide much benefit.
Copying products requires studying what others are doing – one effective method to do this is tracking competitors – by setting Google Alerts with their brand and URL as well as any relevant keywords (e.g. “best toothbrush”) so you can keep tabs on what they post when and if its performance warrants copying it.
Finding an existing profitable Amazon FBA listing that you want to replicate is of vital importance in creating your copycat product listing. When doing this, ensure there’s ample demand and there will be buyers ready for you when you launch your own version (with competitive prices of course!).
Search the Amazon search page results using keywords associated with your niche (for instance “dog chew toy” in the search bar and view each listing to understand their differences – there may even be different kinds of dog toys).
Assuming you already sell one product, expanding your offerings may allow you to find complementary ones. If you sell coffee beans or cups separately, expanding to sell coffee mugs, hot chocolate mix or gardening tools might complement that sale and generate additional revenues per visitor. Extending offerings allows businesses to increase revenues without increasing traffic levels – you could even leverage current offerings by selling combinations together such as selling coffee mugs with coffee beans at discounted rates and vice versa! By diversifying offerings you will increase revenue without increasing traffic levels – while existing offerings could become leverage when used together as leverage when used together – say in combination!
As evidence of their success, consider all the companies which have copied Coca-Cola and McDonald’s formula.
Success lies in finding and replicating an effective formula, rather than trying to reinvent it yourself. Don’t reinvent anything – find something that works and keep reusing it until either it works for you (or someone else does!).
“If you want to be successful, find someone who has achieved the results you want and copy what they do and you’ll achieve the same results.” – Tony Robbins
# Case
It is best to find the specifications of plastic materials on the sample and indicate the location and size of the gate.
These plastic materials usually appear in the form of a triangle.
In the end, you still have to send this sample to your final supplier to facilitate their design.
4 main points related to plastic mold and injection part price
The number of purchases conclusively determines the price of the product and the plastic mold.
As long as the product is only 10,000, do not put forward a requirement of 500,000 because 10,000 shoots required mold steel, mold design, and processing methods are entirely different from the 500,000 requirements.
If the number of products is 10,000, the four-cavity mold can meet the requirements.
If it is 500,000, the mold will require 10, 12 cavities or higher.
The more cavities are, the definitely higher standards of the steel material and processing requirements will be.
This will lead to a significant increase in the material cost and processing cost of the mold.
The considerable quantity shares these costs.
If the quantity is quite small, then the cost-sharing of each product will be considerably high.
I have encountered a case where there is an ABS molded product.
The annual demand is 1500 sets.
It is internally threaded and needs to be unscrewing.
If you need a full-automatic unscrewing mold, the cost will be high, and if the thread is made into an insert.
The cost of the mold is only about 2/3 of the fully automatic mold cost, and the increase in injection molding cost is only small.
In general, dark-colored products need rather lower prices than light-colored products.
Because the regrind material can be carfully used in some cases, if it is a white or transparent product, the regrind material is difficult to use, which will increase the supplier’s raw material costs.
Frequently, the runner material and the new material have the same effects.
The barrel of the injection molding machine is sometimes not so clean, so sometimes other colors will mix in.
If the product requires transparency or white, this product is defective. If it is a dark color or even black, it cannot be seen. This product is good.
As we all know, the processing cost of a loose tolerance plastic part is much lower than that of the tight one.
Molds with tight tolerances have very stringent requirements for processing and mold steel and even require a unique injection molding process.
In general terms, the plastic we choose should be conventional plastics, not engineering plastics.
Nylon66 flare-retardent grade “v0” price is more than four times the conventional PP plastic.
The cost of the ordinary ABS is 1.5 times the price of PP.
If it is mass production, the cost difference is great.
Some plastics are corrosive, so there is a higher demand for the steel of the mold. This will also increase the manufacturing cost of the mold.
There are also higher requirements for mold maintenance.
The price of the steel of the mold s136 level is more than five times that of the steel p20.
Among the three methods mentioned above（autocad files, samples photograph and samples）, sending supplier samples directly is the best method.
In this way, the molder can clearly know the product’s structure and can also find out the structure of the previous mold.
Research on off-the-shelf samples can avoid many detours in mold building and injection molding products.
In short, before the quotation, the more the supplier knows your requirements and the specific structure of the product, the better it is so that the accuracy of the quotation can be guaranteed to the greatest degree.
At the same time, it ensures the smooth progress of the project.
Finding an appropriate injection mold may prove tricky, since there will likely be multiple back and forth conversations with both purchaser and molder before final production commences.
But these tips could save time and make this entire process simpler for you.
When you buy an injection mold, that age-old proverb is unquestionably correct – it gives you everything you pay money for. Any specifically shaped parts that you develop are only as good as the plastic mold used to manufacture them. Therefore, you should make certain that plastic mold is flawlessly designed for your requirements before purchasing it.
