There are two ways to control MIM temperature:

Nozzle temperature. Nozzle temperature is usually slightly lower than the maximum temperature of the barrel, which is to prevent the "salivation phenomenon” that may occur in the through nozzle. The temperature of the nozzle should not be too low, otherwise the nozzle will be blocked because of the melt early solidification. It will also influence the product performance. 

Barrel temperature. The temperature of barrel, nozzle and mould should be controlled during injection molding. The first two temperatures mainly affect the metal plasticization and activity, and the last one mainly affects metal activity and cooling. Each metal has different active temperatures. Even the same metal has different active and synthetic temperatures due to different origin or brand. 

That is because of different average molecular weight distribution. The metal plasticizing process in different injection machines is also different, so that the barrel temperature is different.

We Shandong No2 Machinery Company have very outstanding technology resources, and many master workers with more than 10 years experiences. Also quality Dep. is our biggest human cost, we have strict procedure to make quality better.
