What Are The Main Difficulties in MIM Process Production

What are the main difficulties in MIM process production? The editor has organized a few key points for you.

1. Interface morphology control during injection process. This problem is relatively simple for dual color and synchronous co injection, but in sandwich powder co injection molding, two problems are prone to occur. The first is a breakthrough at the forefront during injection, and the second is the thickness of the core shell layer at different positions of the product, which affects the performance of the product.
After the injection is completed, we need to combine two different materials together through co sintering. But the sintering shrinkage behavior of the two materials is different, so during the sintering process, interface stress is generated due to inconsistent shrinkage, which leads to a decrease in interface bonding strength and, in severe cases, cracking.

 

Generally speaking, this component refers to an indivisible individual component in machinery, which is a fundamental component of the machine and a fundamental unit in the mechanical manufacturing process. The manufacturing process generally does not require assembly procedures. Such as shaft sleeves, bearing shells, nuts, crankshafts, blades, gears, camshafts, connecting rod bodies, connecting rod heads, etc.
Is there a certain standard for selecting MIM parts? This question is certain. The standard generally refers to whether its quality is qualified and whether it can withstand long-term actions. If it is a low-quality part, its usable time will definitely be much shorter than that of a high-quality part, and it will also delay many things. After all, the role played by any product's parts is very important.
