Different types of stainless steel often appear in sheet metal, tubing and wires. In recent years, with the progress of science and technology, the increasingly diversified fields of stainless steel materials are required to be further expanded. Especially in stainless steel as stainless steel parts, the main material of the small size of complex shapes and sizes is the trend of its development.
However, stainless steel is also difficult to be machined at the same time. Because of its high hardness and strength, it is not suitable for the processing of parts. So the injection molding of the front metal appears even today. Many excellent properties of the traditional form of simple stainless steel are produced by precision casting. The size accuracy, surface roughness and shape of stainless steel parts produced by the method are limited, and are easy to segregate.
In addition to the precision casting method, you can also die from the conventional powder metallurgy sintering process to produce stainless steel parts, but in the process of using the low concentration part, the porosity is large, thus reducing its mechanical, corrosion resistance and appearance properties, but only the mold can only produce simple blank shape and simple parts. Technology.
The metal injection molding process uses fine metal powder microns and some organic adhesives to feed small sizes. The complex shape parts of this method have three-dimensional shape and even some three-dimensional components can easily achieve large capacity production. The use of MIM technology for producing stainless steel powder injection components is a variety of different types of stainless steel micron powder. The specific adhesive after mixed granulation is the shape required for injection molding parts. After forming, the parts generally do not need too much follow-up processing and the size accuracy can be up to + 0.3%-0.5%. The density can reach more than 95% of the theoretical density.
Ignition room, inflatable balloon shaft, inflatable balloon pin, etc.: stainless steel powder injection components, such as mechanical, corrosion resistant and surface appearance, can be made of equivalent stainless steel parts, and the common part of the stainless steel powder injection is a forgery part; space components, small arms parts, orthodontic ward, surgical instruments, and medicine Using a gas manifold, an electric toothbrush gear, a watch case strap, a spectacle frame, a cylinder, and other tools such as tweezers, pliers, bits, and some mechanical joints such as "D" and "cross".
