Company Overview
Founded in 2000 and exporting globally since 2002, RCH Precision Machinery Co., Ltd. is a specialized manufacturer of high-performance automotive aftermarket parts. With over 22 years of continuous industrial manufacturing experience, we do not just assemble parts; we engineer mechanical solutions. We focus strictly on producing precision CNC-machined engine components, cooling systems, fuel delivery hardware, and custom-machined upgrade parts for demanding motorsport and high-stress street applications.
Manufacturing Capability & Engineering Expertise
Our operations are housed in a dedicated 2,400-square-meter manufacturing facility, equipped to handle high-volume orders and complex OEM/ODM projects. Production is driven by a workforce of over 50 skilled professionals, heavily anchored by our core R&D and technical team of 15 senior engineers.
We reject fragile cast replacements. Instead, our facility specializes in tight-tolerance multi-axis CNC milling and turning. By working primarily with aerospace-grade materials-such as 6061-T6 billet aluminum-we manufacture premium hardware including 1JZ/2JZ Skline GTR EVO billet valve covers, performance pulley kits, and engine dress-up components that guarantee exact fitment and superior structural rigidity.




Quality Control: Reliability, Classic, Honor
Quality is a measurable metric, not a marketing buzzword. Our company name, RCH, stands for Reliability, Classic, and Honor-the three fundamental principles that dictate our production floor.
To ensure our products survive extreme RPMs and thermal cycling, we enforce strict quality control protocols throughout the entire manufacturing process. From incoming raw material verification (MTS) to final surface treatments like hard anodizing, every component is rigorously inspected. We utilize advanced measuring equipment to verify dimensional accuracy, flange flatness, and precise O-ring channel depths, ensuring a zero-defect rate for our global distributors.

Global Supply Chain Partner
As a reliable B2B supplier with over two decades of international trade experience, RCH understands the critical nature of supply chain stability. Whether you are a performance tuning shop, a wholesale distributor, or an established aftermarket brand seeking reliable contract manufacturing, we deliver exact tolerances, consistent physical performance, and streamlined global logistics.
