High pressure die casting with various aluminum alloys

Material: custom size: according to drawings Our company (Huan-Tai) is rooted in China since mid-90’s. As one of the early runners, we bring value to the table through our capabilities in engineering, quality control and schedule management that meet the high expectations of overseas customers in stability, consistency and predictability. We focus on quality and consistency. Batch production are always consistent with sample. Our Quality assurance: 1. Non-destructive test (NDT): magnetic particle examination (MPE), ultrasonic examination (UE), liquid penetration examination (LPE), X ray. 2. Experienced inspector on dimensions, CMM dimension testing and other tools. 3. To maintain our reputation, we still have excellent return and claim policy even some rare defects. 4. Our prices are always competitive. 5. Spectrometers to assure the material.

Huan-Tai has been a supplier to the aluminum Industry for over 27 years providing dross pans and sow molds to almost every major aluminum producer in our industry. We are specialist in designing castings for cooling slat cake and black dross. On average our multi-chamber castings will improve the overall recovery of salt cake and black dross by 20 - 40% or 3 to 4 aluminum percent in the material. We do this by quickly cooling the slat cake and black dross. Mass matters when processing dross. It is the lowest cost and most reliable and lowest maintenance method for cooling salt cake and dross and preserving metal units. Salt Cake and dross pans in the past were typically designed to a thickness of 38 – 40mm. Holding huge quantities of materials that would take anywhere from 18 -24 hours to cool before dumping. Over time they would distort and crack and need periodic replacement.
