JS Precision provides metal casting services. With 15+ years years of experience, we ensure a 98.8% on-time delivery rate and maintain a defect rate of ≤1.2% to achieve reliable manufacturing.
Adopting high-speed and high-pressure filling technology, metal liquid fills the mold cavity instantly at 0.5-5m/s and solidifies rapidly. Combined with high-precision molds, we ensure casting dimensional accuracy CT4-CT6 and surface finish Ra1.6-Ra6.3.
We work with various alloys, including aluminum, zinc, and magnesium, to meet specific project requirements. Our capabilities efficiently support both prototype development and high-volume manufacturing runs.
We specialize in creating custom solutions for complex, thin-walled parts, particularly for industries like automotive and consumer electronics, helping to streamline production and boost overall efficiency.
High pressure die casting (HPDC) is a precision metal forming process where molten metal is injected into a steel mold cavity under intense pressure, typically between 15-100 MPa. This high-pressure injection facilitates extremely fast filling speeds, enabling the production of components with exceptional dimensional accuracy, smooth surface finishes, and complex, thin-walled geometries in a very short cycle time.
Dominating large-volume manufacturing, high pressure casting is essential for creating lightweight, high-strength parts in the automotive, aerospace, and consumer electronics industries. Its key economic benefits include superior production efficiency, minimal material waste, and excellent cost-effectiveness for mass production of net-shape components.
We offer three custom high pressure casting processes that can quickly respond to your personalized needs, providing high-efficiency, high-precision forming services for precision thin-walled parts.
Injection chamber is immersed in molten metal, no repeated feeding required, short production cycle, optimal for custom zinc alloy precision parts, adapting to fast-iteration scenarios such as 3C electronics.
