Die Temperature – Key Factor for a Quality Die Cast

Conventional quality emphasis in die casting manufacturing dwells on the control over dimensions and hardness but tends to turn a blind eye on the make-art of the surface. Our company is well-versed inthat the tooling temperature is the key factor for product surface quality, and invested a series of tooling thermal control system for the assurance of products dimension consistency and immaculate surface quality.

The following are the advantages provided by the tooling thermal control system:

1、  The delay of tooling cracking

The thermal control system warrants temperature consistency of the die tooling, which prevents spider-web cracking or tooling breakup from elevated temperature during mould injection, while at the same time helps a prolonged tooling life-cycle.

2、 Prevention of parting line deformation affecting the appearance and specification of the finished part

During the casting process, heat-exchange takes place when molten aluminum flows into the dies, causing, at variance, surface expansion of the dies. Our thermal control system can effectively regulate the die temperature, allow the two-halves to meet nice and flat at the parting line, and eliminate parting line deformation, causing porosity defects.

3、  An important role on surface quality, especially for thin-wall product

Our thermal control system manages the thermostatic temperature within the range of 220 – 280 degree Celsius to guard against defects such as flow lines or pores of the ejecting thin-wall part.
