​Generally, it is divided into two categories according to MIM metal materials (iron-based and stainless steel materials), and stainless steel materials are widely used (316L / 17-4PH,)

Produce small metal parts with complex shapes like plastic products, suitable for the manufacture of small parts with complex geometric shapes, high precision and special requirements, usually weighing (0.2-200g);

​Installation requires certain technical instructions and installation requirements. Are you still thinking about the installation of sprockets? Tell you about the installation requirements of sprockets:

The tightness of the sprocket should be suitable. If it is too tight, it will increase power consumption and the bearing is easy to wear; if it is too loose, the sprocket is easy to jump and off the chain. The tightness of the sprocket is: lifted or pressed from the middle of the sprocket, about 2% -3% of the center distance between the two sprockets.

A sprocket is a kind of cog-type sprocket wheel used to mesh with a block with a precise pitch on a link chain or cable. Sprockets are widely used in mechanical transmission in industries such as chemical industry, textile machinery, escalators, wood processing, three-dimensional parking garages, agricultural machinery, food processing, instrumentation, petroleum, etc.

Gear is the main basic transmission components in the automotive industry, usually there are 18 to 30 teeth in each car, the quality of the gear directly affects the noise, stability and service life of the car.

A pin, or pin. A part usually made of cylindrical wood, metal, or other material, especially one used to hold several separate objects together or to serve as a support for one object hanging from another. The pin is cylindrical at one end and tapered at the other, similar to the shape of a bullet. It is one of the fasteners commonly used in modern mechanical equipment. The diameter of the cylinder is an important data to distinguish its specifications.

MIM has the largest application in auto parts manufacturers, and there are relatively few MIM enterprises doing auto parts in China, but MIM has great application potential in automobiles.

As a near-net forming technology for manufacturing high-quality precision parts, MIM technology has incomparable advantages over conventional powder metallurgy, injection molding and precision casting methods

Metal injection molding (MIM) is a kind of from the plastic injection molding industry, bring out a new type of powder metallurgy near net shape technology, as is known to all, plastic injection molding technology of low prices in the production of all kinds of complicated shape products, but the strength of plastic products is not high, in order to improve its performance, can be added in the plastic metal or ceramic powder to products have high strength, good abrasion resistance.

Powder metallurgy alloy steel is a kind of alloy steel made by hot isostatic pressure or hot extrusion technology, which compacts the alloy steel powder into blank and then is processed by general thermoplastic process. The density is close to or equal to the theoretical density.

Black steel is just plain steel. Is in order to increase the corrosion resistance of steel, steel surface with agents for blackening treatment. Generally, steel is processed into a variety of practical tools. After heat treatment, all kinds of fasteners still need to be galvanized or blackened to increase the corrosion resistance of the workpiece.

ecause of micro powder injection molding technology has evolved from the traditional powder injection molding, so the technology of process steps and powder injection molding technology basic same, namely, feed preparation, preparation of raw material powder and binder uniform mixture), injection molding (will melt feeding filling into the mold cavity, be preformed billet), skim, completely remove the adhesive in the green component, that is, get skim billet) and sintering (will skim billet heat treatment, make its have certain density and mechanical properties).

In the 1930s, the powder metallurgy process successfully manufactured porous oil bearing, with the use of cheap iron powder, powder metallurgy process began to be widely used in automotive, textile and other industrial fields. In recent years, powder metallurgy has gradually become a processing method for manufacturing new materials. Powder metallurgy has been around for more than 100 years and over the past 25 years has become a recognized quality technology for producing a wide range of high-quality parts. Compared with other metal forming technologies, such as forging and casting, this technology has advantages in material utilization, shape complexity and near-net forming size control, etc. Powder metallurgy is recognized as a green technology due to its nature of promoting sustainable development.

The injection molding process is the main process of MIM technology, which can be divided into the following main steps

The generator, the highest and most essential source of electricity in a power plant, is the most fiercely protected of all the other devices that compete all day long to get it going.

Powder metallurgy technology, which integrates material preparation and parts forming, is an advanced manufacturing method for automobile manufacturing, high-end mechanical processing, new energy development and utilization, and materials used in aerospace. It plays an important role in energy saving, metal saving, strategic material saving, labor productivity improvement and environmental protection.

Computer and auxiliary facilities: such as printer parts, magnetic core, firing pin shaft pin, drive parts;

MIM technology combined with powder metallurgy and the advantages of the two big plastic injection molding technology, break through the traditional metal powder moulding the limitation of forming process on the product shape, at the same time using the plastic injection molding technology can bulk forming parts with complex shape, high efficiency, the characteristics of the modern manufacture high quality precision parts of a near net shape technology, with the conventional powder metallurgy, machining and precision casting processing methods, such as the incomparable advantage. ​

In recent years, the rapid development of precision forging technology has promoted the progress of automobile manufacturing industry. Cold forging and warm forging are more and more used in automobile industry, and the product shape is more and more close to the final shape. Precision forging will be developed with the progress of technology and related technology in the future.
