Custom High‑Precision Aluminum Alloy gravity Casting parts

Aluminum gravity casting is a professional molding process that fills molten aluminum alloy into mold cavities purely by gravitational force. Different from high-pressure die casting and vacuum casting, this technology requires no external pressure or vacuum assistance. It features simple operation procedures and outstanding cost-effectiveness, making it highly suitable for mass production and customized manufacturing of aluminum alloy castings with complex structural shapes.

Longkou Kaiste Metal Products Co., Ltd. is an integrated manufacturer specializing in the development, design, production and sales of high-quality aluminum gravity die casting parts. With years of in-depth industry experience, we provide a wide range of aluminum castings with complete alloy grade specifications to meet diversified customer demands.

To deliver one-stop manufacturing solutions, we offer comprehensive supporting processes covering sand casting, low-pressure casting, CNC precision machining, anodizing, electroplating, polishing and powder coating. Our integrated service system greatly shortens the production cycle and ensures consistent product quality for clients.

Our customized aluminum gravity casting components are widely applied in multiple core industries, including motorcycle and automobile manufacturing, rail transit, printing machinery, hydraulic equipment, automated machinery, food processing machinery and robot equipment and gravity casting flange series. Adhering to standardized production management, the company has obtained the ISO9001:2016 Quality Management System Certification.

We are equipped with professional precision testing equipment to implement full-process quality control. Strict inspection and process control are carried out to effectively minimize casting defects such as porosity and sand holes, ensuring high precision and stability of finished products.

Guided by the core principle of “meeting customers’ diverse requirements” and the development goal of “strict quality control and continuous efficiency improvement”, we are committed to providing global customers with high-reliability aluminum gravity casting products with stable quality and competitive prices.
