GZHD Lightweight Forming Technologies Co., Ltd was established in 1995. GZHD is a new high-tech enterprise specialized in R & D, new technology research, and production on aluminium base lightweight material products.
GZHD has many intra-industry well-known specialists and scholars, master advanced technology of liquid die forging technology research, semisolid squzee casting and foamed aluminium technology in China. GZHD can offers all processure services in facility production, metiral research, process development and production in aluminium base new material & lightweight area.
Core Technologies
Squeeze Casting (Liquid die forging) Technology
Squeeze casting is also called “Liquid die forging”. The principle of the process is to utilize mechanical high pressure (about 100MPa) to the entered liquid metal or semisolid metal of mould cavity, then be solidified to get casting parts.
Because of high pressure solidification and plastic deformation concurrenced, casting parts become compact texture, grain refinement, without porosity and loose these weakness. Then go on deal with T6 heat treatment. The property of the squeeze casting is better than the normal casting obviously, and approached the level as the same kinds of alloy forging parts. Squeeze casting is a choiceness process for lightweight development.
There are two important stages of the liquid die forging are mold filling and solidification, and two typical characters are low-speed mold filling and rapid high pressure solidification-feeding.
Semisolid Squeeze Casting Technology
Semisolid squeeze casting is integrated the semisolid production with squeeze casting as a one. This is a new material production technology that utilized the theological property of semisolid size to pour and fill the mold, and then solidified forming under the pressure.
Due to the semi-solid process, so the quality defect of liquid die metal decrease efficiently, combined with squeeze casting will get choiceness parts products with better property indicator.
Component performance objectives: Tensile Strength ≥ 500Mpa, Yield Strength ≥ 400Mpa, Ductility ≥ 12%

In the two years' development, GZHD estblished Guangdong (HQ), Mogolia (Mogolia Boshun Hede Precision manufacturing Co., Ltd.), Jiangsu (HD Auto parts lightweight technology (Suzhou) Co., Ltd.) — three production bases gradually, and going to bulid up more production bases at Shandong Binzhou, Henan Zhenzhou, and Sichuan Chengdu these cities. Hede will become an excellent high-tech enterprise with core tech competence.
