Zhengheng Power’s diversified casting processes empower

the intelligent manufacturing of high-end components

Zhengheng Power has deeply cultivated in the field of precision casting, relying on an intelligent production system to establish a core process matrix encompassing high-pressure die casting, low-pressure die casting, and gravity casting. Its business covers various fields such as automobiles, high-end motorcycles, aviation, ships, and construction machinery. It can adapt to the production needs of castings of different materials, specifications, and batches, providing high-quality castings and one-stop intelligent manufacturing solutions for global OEMs and new energy vehicle companies.

1. High-pressure die casting: core technology for large-scale precision mass production
High-pressure die casting boasts advantages in high-pressure, high-speed, and high-precision mass production, featuring filling and molding under working conditions of several to tens of megapascals of high pressure and 10-50m/s of high speed. The product precision reaches IT11-IT13 levels, with surface roughness as low as Ra1.6-6.3μm. It has small machining allowance, high casting density, and balances lightweight and structural strength. It is suitable for aluminum alloy, zinc alloy, and magnesium alloy materials, with strong automated continuous mass production capabilities. It is mainly used for core components of new energy vehicles such as cylinder blocks, motor housings, and transmission housings, with excellent mass production stability and yield rate.

II. Low-pressure die casting: the main process for high-density precision castings
Low-pressure die casting utilizes a stable filling process at a low pressure of 0.02-0.15 MPa, eliminating vortex and splash, thereby reducing defects such as air holes and cold shuts from the source. It can form ultra-thin complex internal cavity structures of 0.8mm thickness, resulting in finished products with excellent mechanical properties, high batch consistency, low mold wear, and adaptability to medium-volume high-quality production. It specializes in castings such as aluminum alloys, and is widely used in high-performance applications like automotive cylinder blocks and heads, suspension components, as well as high-end motorcycles and aviation precision accessories.

III. Gravity casting: a highly adaptable and cost-effective universal process
Gravity casting relies on the self-weight of the molten metal to fill the mold, featuring a mature and stable process, short debugging cycles, and low equipment investment costs. It is compatible with multiple materials such as cast iron, cast steel, and aluminum alloy, and is not limited by casting wall thickness. It is suitable for a wide variety of small-batch trial production and mass production, with a long mold service life. It is widely used in automotive power components and engineering machinery structural parts, supporting the entire production chain from sample development to mass production.

The diversified casting processes complement each other, achieving full coverage of mass production and customized scenarios. In the future, Zhengheng Power will continue to iterate on casting processes and intelligent manufacturing systems, leveraging its diversified precision craftsmanship capabilities to continuously empower the high-quality development of the automotive and high-end equipment parts industries.
