Intelligent manufacturing has revolutionized the industry, and 3D printing is one of the most significant breakthroughs. The latest technologies in 3D printing have made it possible to produce high-quality finished products in a shorter time frame, featuring faster set-up, low entry cost, and flexibility in dealing with frequent design changes.

The simulation and modeling software tools on the other hand can help to predict the performance of the parts and possible defects based on the material characteristics during teh molding process. Furthermore, these tools are capable of reducing the cycle times and optimizing the tools for plastic injection molding.

Greater Automation:

Boosting automation enhances production efficiency severalfold. In the case of plastic injection molding welcoming the advancements in robotics has a direct impact on production efficiency, labor costs, and product quality.

It&#;s safe to say that the injection molding sector is in the process of digitalization and manufacturers are adapting to IoT (Internet of Things) and AI technologies. This enables plastic injection factories to run production remotely, monitoring the conditions by digital means and getting alerts and updates as needed. 

Cobots aka collaborative robots are more of assisting robots working alongside human machine operators relieving them from repetitive tasks, some of which could be hazardous. All-in-all, these technologies help reduce the risk factors of certain production processes and give a break to the technicians from mundane tasks, with a great turnaround time.

Circular Economy & Sustainability:

Manufacturers from across countries are aiming to develop trends to recycle and reuse plastics better during the production process. The idea is to adapt to a circular economy to reduce waste and pollution and circulate materials and products at their best. 

By nature, plastic injection molding makes efficient use of the material, however, the weight control software helps measure and maintain a consistent weight on each shot given the viscosity difference that happens to raw materials after re-granulation

As more manufacturing companies commence to realize the potential of sustainability in injection molding, they are developing thoughtful approaches to product design and production processes, ensuring less waste and enhanced efficiency. 

Varying Industry Demands

The injection molding industry is witnessing varying demands driven by different sectors and has to be customized. One significant trend is the surge in demand from the packaging industry, fueled by the growth of e-commerce, for which injection molding offers a cost-effective solution for mass-producing packaging materials such as plastic containers, bottles, and caps. 

The medical industry is another sector that is driving demand in terms of cleanroom molding, which ensures the production of medical devices and components in a controlled environment, minimizing the risk of contamination. The investment in specialized cleanroom facilities and implementation of stringent quality control measures to cater to the growing demand for cleanroom molded medical products.

Furthermore, the automotive industry is actively seeking innovation in injection molding technology, exploring ways to reduce vehicle weight, improve fuel efficiency, and enhance overall performance. Injection molding enables lightweighting through the use of advanced materials and complex designs. Additionally, integrating functionalities within molded components, such as sensors and electronics, is being explored to enhance safety and connectivity.

Material Durability and Innovation:

Lightweight preference is quite evident from consumers across industries and hence the trend creeps on to injection molding as well. This eventually has a positive impact in terms of transportation, energy efficiency, and product performance.

There is a rising consciousness of sustainability and environmentally friendly materials. Hence, Bioplastics as natural alternatives that are carbon-neutral, compostable, and bio-degradable are taking over.

On the other hand, manufacturers are elevating their focus on durable materials that can withstand high temperatures and extremities of production. Thermoset materials and engineered plastics are taking the main stage on this front

How New Technology in Injection Molding is Advancing ...

Plastic is everywhere. Often configured through injection molding processes, it is used in packaging, construction, consumer products, textiles, electronics, and automobiles, to list just a few instances. However, decades of plastic production without a robust recycling strategy have resulted in discarded plastic products clogging the environment.

Utility vs. Environment

The global community relies on plastic and plastic injection molded products to provide innumerable services across almost every sector and industry. The malleable material also adapts to virtually any shape and provides strength, flexibility, and unmatched durability. These product assets are just some of the reasons why the use of plastic isn&#;t diminishing but instead is expected to grow.

As demand continues, however, plastic waste must also be addressed, the volume of which is already astounding:

  • In , more than 242 million metric tons of plastic waste were generated by the global community, which represented a full 12% of all municipal waste.
  • As of this year, the world is consuming twice as much plastic as it did 20 years ago. And of that volume, only 9% is actually recycled.

So why is so little plastic recycled? The short answer is that the chemistry that goes into making plastic products and parts differs based on the type of plastic being used. These various types of plastic have to be sorted to be properly recycled. For recycling purposes, resin types are numbered from one to seven and are indicated within the triangle on most plastic products. The sorting of the various plastics based on their foundational resin makes recycling plastics an elaborate and challenging proposition.

Resin code identification has been used for decades to help consumers identify and sort plastic accordingly. However, more recently, municipal recycling centers have been accepting commingled (1-7) plastics and utilizing expensive sorting equipment to sort the plastic. This works well unless the package is made with two different resin types, like laundry detergent, shampoo or other similar bottle:

  • Polypropylene resin (PP), for example, can be injected at a relatively low pressure to create an injection molded plastic product and is used to make the cap for these types of packages
  • Polyethylene resin (PE), on the other hand, is chemically inert and has a large strength-to-density ratio which works well to create the blow molded bottles
  • Until now, neither of these materials would be used in the others place:
    • Bottles which hold various materials require the strength and chemically inert PE
    • High pressure is needed to inject PE and in many cases the injection molding machine may be pressure limited when trying to process PE for caps

iMFLUX Injection Molding Technology Platform

Challenge Accepted

iMFLUX&#;s innovative injection molding technology brings precisely the right opportunity to facilitate the recycling of plastic products while also opening new avenues for plastics industry growth. The technology allows for the creation of a mono-material, easy to sort bottle/cap package.

Because the innovative injection molding technology operates at a low constant pressure, PE can be utilized to make injection molded parts that were not previously created with PE. The resulting package becomes easier for the consumer and recycling center to handle.

The platform provides several unmatched benefits to injection molded parts and product producers:

  • It installs directly into existing molding machinery, so there is little downtime, and enhanced molding capabilities are available immediately.
  • Its low-constant-pressure assures a high-quality shot every time.
    • The closed-loop, low-pressure injection process ensures that the material flows evenly through the mold and packs each cavity as it fills.
    • A melt pressure sensor within the system monitors for pressure changes caused by gates, gaps, etc., and the automated software moderates the pressure to accommodate those changes.
  • Most importantly, from a sustainability perspective:
    • The system monitors relative viscosity and moderates pressure to accommodate variances when using alternate materials.
    • The platform enables the use of resins where they were previously assumed not to work.
    • The injection molding machine will operate at lower pressure, temperature, clamp tonnage and more to provide a significant energy savings on each machine it operates.
