Vulcanization treatment of MIM products

Purpose of vulcanization treatment: When vulcanization is used as anti-friction material in powder metallurgy products, iron-based oil-impregnated bearings are the most widely used. Sintered oil-impregnated bearings (with graphite content of 1%-4%) have simple manufacturing process and low cost. ... Read More

Brief introduction of sintering process of iron-copper-based MIM parts

The influence of sintering process parameters on the performance of iron-based parts Sintering process parameters: sintering temperature, sintering time, heating and cooling speed, sintering atmosphere, etc. 1. Sintering temperature The selection of the sintering temperature of iron-based produc... Read More

The principle of MIM compaction-A

1. Definition of forming Densify powder into green compacts with a certain shape, size, porosity and strength, the process is the MIM forming. 2. The importance of forming 1) It is a basic powder metallurgy process whose importance is second only to sintering. 2) It is more restrictive and determ... Read More

Sinter hardening in MIM

What is Sinter Hardening? Sinter hardening is a process that produces martensite transformation during the cooling phase of the sintering cycle. That is the sintering and heat treatment of powder metallurgy materials are combined into one process, so that the material production process is more ... Read More

Infiltration Process of powder metallurgy

The powder compact is contacted with liquid metal or immersed in the liquid metal, the pores in the compact are filled with liquid metal, and the compact material or parts is obtained by cooling down. This process is called immersion. The immersion process relies on the external molten metal to w... Read More

The atmosphere of Sintering in MIM

The atmosphere during sintering process is the keypoint for MIM technology, it decide the sintering result and the final performance of products. Today, we will talk about it, the Atmosphere of Sintering. The Role of sintering atmosphere: 1) Dewaxing zone, remove the lubricant in the green body; ... Read More

Sintering process of MIM

Let us continue to introduce every process of Metal Injection Molding technology. Today we will discuss about the sintering which is the most important points during MIM.   THE BASIC KNOWLEDGE OF SINTERING 1) Sintering is to heat and hear the powder compact at a temperature lower than the me...
