We produce accessories such as engine connecting rods, piston bodies, cylinder heads, etc. for North American companies. 

As a high-quality partner in the North American automotive engine industry, we are dedicated to the precision manufacturing 

of high-end aluminum alloy engine accessories. 

Relying on five-axis simultaneous CNC machining centers and digital control throughout the entire process, we custom-produce 

core components such as engine connecting rods, piston bodies, and cylinder heads for our customers. 

We select high-strength forged aluminum alloys (such as 2618-T61) and the special casting alloy A356. Combining vacuum die-casting 

with precision aging treatment processes, we ensure that our products possess excellent anti-knock performance and high-temperature resistance. 

All accessories have passed the SAE J455 material certification and undergone 100% coordinate measuring machine (CMM) inspection. 

The dimensional accuracy reaches ±0.01mm, and the surface roughness Ra≤0.8μm. We strictly adhere to the IATF 16949 system and adopt an 

environmentally friendly water-based cutting fluid process to help our customers create efficient and reliable power system solutions.
