Introduction to Processing Types

In the course of powder metallurgy, metal powders are mixed and pressed, and the formed body shall be sintered to achieve the required mechanical properties. The sintered bodies need to undergo machining, heat, and surface treatments. This method can be used to produce auto parts, hand tool parts, sewing machine parts, power tool parts, pneumatic tool parts, belt pulley parts, gear parts, woodworking machine parts, locking parts, auto lubrication bearings, etc.

MIM is suitable for manufacturing products with small and complex shapes, high dimensional accuracy, high toughness, and high precision, thus eliminating the need for precision machining and reducing material consumption.

It is widely used in the production of computer and electronic parts, medical devices, auto parts, bicycle gears, hand tool parts, pneumatic tools, power tools, sewing machine parts, locks, lock cylinders, photocopier parts, and drive shafts, etc.

Lost wax casting makes it easy to carve the wax to make the product, and after the metal is cooled, the refractory clay is opened to obtain the final metal casting product. There are no restrictions on the materials used in casting. It is mainly used to produce stainless steel, carbon and alloy steel, low-alloy steel, aluminum alloy steel, and tool steel.

Products made of aluminum alloy have the advantage of lightweight. Based on different usage requirements, materials of different hardness can be used in these products to ensure the durability and strength of the workpiece. Besides, these products can be manufactured by extrusion, casting, gravity casting, or forging according to appearance and size requirements.

Forging is divided into hot, cold, and warm forging. Forgings have good physical properties, high strength, and good toughness, which can change the metal structure and improve the mechanical properties.

This method is suitable for manufacturing parts with special shapes. With the help of CNC lathes and CNC processing equipment, this method can achieve stable control of roughing dimensions according to product requirements.

Stamping refers to the use of a punch or special machine to press a material to shape and compress the object.

The stamping can be used to produce light and rigid products with uniform quality, allowing for high reuse and cut recovery of materials.
