Metal powders can be used as raw materials, but because they are not cohesive, they are in an uneven state. Therefore, in the processing should be added to the adhesive as a necessary component or product, so that the molding can be accelerated to a certain extent, if the direct method of operation, the use of powder materials will be different.

General knowledge of injection molding operation: pressure in the process of injection molding includes plasticizing pressure and injection pressure, and directly affects the plasticizing and product quality of plastics.

Generally speaking, this injection molding has a short cycle, high productivity, complex shape, high size requirements and plastic parts with various inserts, which is better than other processes to some extent. At the same time, attention should be paid to the operation:

What factors will affect the shrinkage rate of injection molding

Thermosetting plastic injection molding is a process of physical and chemical changes, and is irreversible, because the material by the screw shear mixing friction heat, its temperature will be higher, so that can quickly dispose of the article, but there are still defects in the process, we need to solve in time.

The cost of injection molding equipment and mold is low. In mass production, the investment is only 1/4 to 1/2 of that of general injection molding. At the same time, there are many methods to meet the needs of different fields and improve the overall production efficiency.

The molding process, the processing, will affect its performance, due to the lack of knowledge, in general, the basic characteristics are often overlooked, while simply manufacturing a template from a component is a fault, where the polymer melt will have some trouble, we must pay attention to.

The first step in making hand tool parts with the MIM is to make a stainless steel feed by placing SUS440C powder and water-soluble binder into a mixing mill and granulator to make the feed.

For the glue of the MIM, it is the core of the MIM technology. In the MIM, adhesives have two basic functions: they enhance fluidity to fit injection molding and maintain the shape of the billet. In addition, it should also be easy to remove, pollution-free, non-toxic, reasonable cost characteristics. As a result, various adhesives have emerged. In recent years. It is gradually changing from a simple adhesive to a non-toxic one. ​

It is usually expressed by the compression ratio of the powder body before and after pressing. The compressibility of powder is mainly determined by its hardness, plastic deformation ability and work hardenability. The powder after annealing has good compressibility.

The characteristics of metal powder have great influence on the pressing, sintering process, pre-sintering strength and final product performance.

​Metal powder production has a variety of methods, including: mineral reduction method, atomization method, mechanical crushing method and so on.

Powder pressing (mainly referred to here as powder metallurgy) is the process of making various kinds of shaped parts and products from metallic powders (or mixtures of metallic and nonmetallic powders) as raw materials by pressing and sintering.

History of powder metallurgy The use of powder metallurgy dates back to more than three thousand BC. The first method of making iron was essentially powder metallurgy. And modern p/m technology

As is known to all, aluminum alloy parts have high strength, good plasticity, excellent electrical conductivity, thermal conductivity and corrosion resistance, can be used to heat treatment to obtain good mechanical properties, physical properties and corrosion resistance. The processing of aluminum alloy parts is the processing of aluminum materials through lathes, CNC computer gongs, according to the needs of subsequent sandblasting, polishing, drawing, electroplating, spraying, anodizing, radium carving and other processes. The appearance of aluminum alloy parts is rich in unique metal texture, and the weight is light, heat dissipation is strong, favored by all industries.

Plate in some cases called the first version, as the name implies is not a large number of production before, according to the product appearance drawings and structure drawings generally made a small number of samples, used to check the product appearance or structure reasonable function template.

The production of Indian metal injection molding companies is mainly oriented overseas. About 95% of the metal injection molded parts produced by India are for export. The main components of India's domestic metal injection molding market are: defense, automotive, textile and medical equipment.

Powder microinjection molding: Powder microinjection molding technology has made great progress in the application of micro metal and ceramic component molding. In particular, the application of this technology in metal forming enables micro-components to obtain high strength, good corrosion resistance, high temperature stability, excellent magnetic properties, and abrasion resistance. Using this technology can save expensive assembly costs for micro-components.

As a near net forming process for producing complex parts at a lower cost, powder injection molding integrates powder metallurgy and injection molding processes, and is suitable for near net forming of metal, alloy, ceramic, composite materials, etc. According to the classification of powder, it can be divided into two types: metal injection molding (MIM) and ceramic injection molding (CIM).
