Small or complex parts are difficult to produce by casting or machining. Components that require sintering are often delicate, intricate, and easy to botch. Vacuum sintering is an efficient way to join parts with minimal waste.Vacuum sintering produces consistent, bright parts with no seams, joints, or fillers. Powdered metal, metal injection molding, 3D printing, and other similar technologies can benefit greatly from the superior quality and flexibility of vacuum sintering.

Sintering starts with debinding.
The debinding process removes binder materials that can contaminate the furnace and the final product. Binding materials are originally necessary for each separate part compaction, but become unnecessary and undesirable during the sintering process.
Vacuum sintering requires a high vacuum for clean, quality parts. The temperature must be high enough for the metals to combine smoothly, but not so high that they liquefy. Cooling speed will depend on the material.
Temperature and pressure limits can be chosen during the engineering phase, and controlled manually or automatically during processing.
Vacuum furnaces can be built to perform both debinding and sintering. Combining these processes in one furnace saves time and money. No part transfer, secondary machinery, or resources wasted on a repetitive process.
Vacuum furnaces are perfect for higher temperature sintering applications. Highly customizable controls allow for manual or automatic temperature changes depending on the needs of your specific project. The temperature is uniform, ensuring consistent part quality across the board.
Additive manufacturing (AM) is the industrial production name for 3D printing. The addition of a vacuum sintering furnace or dry oven to the AM process has allowed for the 3D metal printing of parts and prototypes that are cost-effective and accessible. Read on to learn more about the vacuum sintering furnace , its role in additive manufacturing and why Sentro Tech is the place to find the best vacuum sintering furnace or dry oven for your business.

Sintering is defined as creating a solid material mass using heat and pressure &#; without liquefying the material. Vacuum sintering is a heat treatment used to join parts with the least waste to produce consistent components without seams, fillers or joints. The components treated using a vacuum sintering furnace are often intricate, delicate and tricky to make. Benefits of vacuum sintering include:
Additive manufacturing deposits material &#; usually in layers &#; to form three-dimensional objects. The 3D printing process was introduced in as a cost-effective way to create plastic parts and prototypes. Thanks to advances in technologies, you&#;re now able to create 3D objects in metal and ceramics as well as plastic. For 3D metal printing, powder bed fusion is preferred over direct energy deposition. In the powder bed fusion method, a laser or electron beam fuses metal powder particles point-by-point, building up layers until the object grows to its final form.
Despite the expense, metal 3D printing equipment is not a stand-alone operation. Components created through 3D metal printing still require meticulous thermal sintering to help them achieve the requisite hardness, size and density. If you fail to take this essential finishing step, you may wind up with faulty components or parts that require extensive mechanical finishing.
3D printing equipment has revolutionized the future of manufacturing in three main areas:
Many industries have come to rely on 3D metal printing. From base metals to precious metals, the variety of materials implemented in 3D printing is impressive. Thanks to global innovation, the use of additive manufacturing in metal printing has become essential, particularly in these industries:
