Technology Introduction

High vacuum die casting technology 01

By using the vacuum casting control system, the mold cavity is?always?kept in a?negative pressure state, from when the molten metal?has the?low-speed filling to the end of the die-casting process. As a result, the metal liquid filling resistance?is greatly reduced, the sharp drop of the melt flow rate?is avoided, and the mixing of the molten metal with?the gas in the mold cavity is greatly reduced. High vacuum die casting technology is a casting process that can?manufacture high-density castings?of uniform internal structures and can?prevent the occurrence of aluminum spray?and?casting burrs.?

Ultra low speed laminar flow extrusion casting 02

By adopting an extremely low-pressure injection speed, the molten metal fills?the mold cavity?in sequence?with an extremely low filling speed (<0.3m/s).?The?stable?low-speed injection can smoothly discharge the gas in the mold cavity, thus avoiding the?large amount of air entrainment caused by ordinary?high-speed injection?and?greatly reducing the gas content of the castings. Meanwhile, during the solidification process of the castings,?certain static pressure (up to 100Mpa) can be put on?to supplement the solidification shrinkage of the molten metal, so as to obtain the?very low gas content and extremely?dense internal castings.?Ultra low speed laminar flow extrusion casting is such a?die casting process.

CNC high-pressure point cooling technology 03

After the aluminum liquid enters the cavity, the water flow is pressed into the cooling water pipe through the high-pressure control module, to help solve the problem that?the mold is partially elongated?and that the insert?parts?have?an uneven temperature. The technology avoids problems such as hot cracking, aluminum sticking, shrinkage or deformation due to?partially?excessively high?temperature.

Partial compaction pin technology 04

After the high-speed injection is completed and the pressurization is maintained for a period of time, the ingate will be?completely solidified. When the thick part of the casting is solidified?while no?molten metal can?be transferred from?the ingate?to supplement?shrinkage, additional partial?compaction?forces?will be activated,?which will strongly compensate?for shrinkage and flatten the pores. Partial compaction pin is such a process. It avoids?the volume shrinkage occurring during the solidification of the molten?metal in the thick part of the castings, avoids?the defects of internal porosity?and shrinks, and improves?the compactness of the casting internal structure?and?the pressure resistance?of the castings.?
