The selection criteria of powder metallurgy are introduced in detail

Powder metallurgy is a process for making metal powder or metal powder (or mixture of metal powder and non-metal powder) as raw materials through forming and sintering, making metal materials, composite materials and various types of products. There are certain standards for the selection of powder metallurgy. Next, we will introduce the selection criteria of powder metallurgy to you in detail.

1. Partial size: the size of powder metallurgy parts is limited to the compression of powder and molding press. For general steel powder metallurgy materials, the following parts can be prepared: the projected area is less than 32000ram.

2. The diameter is less than 175mm or less than 300ram (big-hole parts); MIM technologists have found that if the product is designed to use non-ferrous materials, the projected area can be increased by 50% in 2 parts: the geometric shape of the part should be suitable for vertical uniaxial compression. Undercutting and concavity or threads are usually formed in subsequent machining or machining. Dahong new material reminds us that when the cross section of powder metallurgy parts changes, the moulds in the forming press need to have different actions. These restricted parts only have five workstations, but with the die design it is possible to add small changes in the part length direction (table). When the length of the powder metallurgy part is greater than 25.4mm, the density will be different from the top (density) to the middle (low density).

3. Part number: metal powder injection molding manufacturer shall discuss the feasibility of quantity cost and production order quantity in view of the use of "hardware" for special moulds.

4.Mechanical/physical performance requirements: standard 35 provides a wide range of design performance to contribute to the selection of suitable materials for most product applications. (6.4-6.9g/cm3) medium density steel can replace cast iron or plain carbon steel; High density grade (7.0 - all/focus) universal alternative to ductile iron and heat treated steel, powder forging and non-porous material systems are commonly used as substitutes for high-performance steel. If the critical performance requirements of the part design exceed the standard values listed in the standards, the requirements shall be detailed in the engineering drawings, the new material of daihon finds.

In order to select good MIM material properties and costs and the feasibility of both, it is important to discuss the application of the components with the powder metallurgy parts manufacturer.

To avoid unclear or misunderstanding, the concept of metal powder injection molding manufacturer production of powder metallurgy parts should be before the manufacture of powder metallurgy parts, when meet the following conditions: the intensity values, brand choice, chemical composition, acceptance testing, performance standard and powder metallurgy manufacturing process, because these may affect parts.
