We serve global equipment manufacturers with customized elevator parts weighing 6.5kg using A380 aluminum material. With a production capacity of 5,000 pieces per unit and 70% export ratio to US, European, and Japanese markets, your components benefit from ISO 9001:2015, ISO 14001, and ISO 45001 certified quality management.

What Is Low Pressure Aluminum Casting?

The product is a precision metal forming process where controlled gas pressure between 0.3 and 1.5 bar pushes molten aluminum upward through a riser tube into mold cavities. This method excels at producing complex, thin-walled components with superior mechanical properties.

Unlike gravity or high-pressure methods, this process maintains consistent pressure during solidification. The result is parts with minimal porosity, excellent surface finish, and enhanced structural integrity.

Your manufacturing projects gain significant advantages. The controlled filling reduces internal defects and improves dimensional accuracy. This makes the process ideal for structural components requiring both strength and lightweight properties.
