The processing technology and extrusion method of hollow aluminum profile and solid aluminum profile are basically the same, and the difference lies in the mold used.
For the mold of solid aluminum profile, only need to process the forming hole in the mold, and then it can be extruded by the extruder. For hollow aluminum profiles, the mold is composed of two parts: an upper mold and a lower mold. The lower mold is processed into the shape of the aluminum profile, and the upper mold is processed into a hollow part shape core, and then the upper mold core is fixed on the lower mold. In the cavity of the mold, a welding chamber is also designed between the upper mold and the lower mold. In order to get aluminum into the mold cavity, Shenghai Aluminum was founded in 2010 and is located in Foshan. It is a professional manufacturer of aluminum profiles that integrates mold development and design, aluminum profile extrusion, deep processing and project installation. High-tech enterprises. Rely on high technology and high quality to take the path of quality and benefit-oriented development.
There is also a shunt hole on the upper die. The aluminum flows to the welding chamber through the shunt hole. The aluminum is re-welded under high temperature and high pressure, and the die hole is extruded to become the hollow aluminum profile we need. Since the mold used for the hollow aluminum profile is composed of two parts, we call the hollow aluminum profile mold a combined mold, and some are called a split mold because the male upper mold has a split hole.
