We are an ISO/TS 16949 certified company showing our determination and insistence on quality and continuous progression.
Our QC dept. takes charge of the production quality. We check every step of the processes such as the inspection of forging material, daily process inspection, and final product inspection. Besides, the MSA and SPC analysis also show that our process stability and measurement system are reliable. We have faith to deliver excellent products to our customers.

Following shows the MSA analysis of our bore gauge. Results show that all the MSA requirements including stability, bias, linearity, repeatability, and reproducibility are qualified. Of course, other measurement systems are also qualified to ensure our measurements are reliable.
Following shows our SPC results of big-end bore diameter. The Cpk of big-end bore diameter is 2.57 (which should be larger than 1.33) showing our excellent process control on the con-rods production.
We developed all machined surface type rods to precisely control the weight of rods. Excellent weight control can assure excellent dynamic performance at high RPM.
Our fracturing-splitting technique have been developed for more than ten years. The irregular cutting surface results in an excellent assembling repeatability. Following Chart shows the reassembling result of our product. Results show that the bore diameter and roundness is almost the same after reassembling.
