Melt pump heat treatment process for the a pair of gears

The gears of the melt gear pump are vulnerable parts. How can we make them more durable during the production process?

1. Blank heat treatment: First, carry out preliminary heat treatment by normalizing or quenching and tempering before and after gear blank processing. The purpose of heat treatment is mainly to eliminate the residual stress generated by forging and rough machining, and improve the cutting performance of the material.

2. Tooth surface heat treatment: After the tooth profile processing is completed, in order to improve the hardness and wear resistance of the tooth surface, it can be realized by heat treatment processes such as carburizing and quenching, high-frequency quenching, carbonitriding and nitriding.

There are many kinds of gear heat treatment methods, commonly used are overall quenching, high-frequency quenching, nitriding, carburizing quenching, vacuum quenching, etc. We will select the appropriate gear heat treatment process according to the actual production conditions of the user to meet the production needs of the conditions.
