Our Facility
🏭 Modern 3,000m² Factory in Wanjiang
We operate from a modern 3,000m² facility in Wanjiang's Xinhe Industrial Zone, equipped with high-speed 5-axis CNC centers sourced from Germany, Japan, and the US.
Our machine shop runs 24/5 production, producing custom CNC turning and milling precision machinery parts ranging from 2mm micro-machining up to 1,200mm large-format components. No MOQ — prototypes to million-piece production runs.
We manage the entire supply chain in-house: material sourcing, CNC machining, CMM inspection, surface finishing, and DDP logistics for aluminum and stainless steel industrial components.

Quality Assurance
🔬 Every Part CMM-Inspected
Every part we ship is CMM-inspected on coordinate measuring machines. Full dimensional report included — no extra charge.
Critical dimensions are checked on CMM against the drawing and shipped with measured values. First Article Inspection (FAI) is free with every new part, covering dimensional, material, and surface finish verification.
Our ISO 9001:2015 quality management system is certified by Zhongyang Certification Co., Ltd. on a three-year audit cycle (certificate no. 93726Q00307R001, valid to 21 September 2029, verifiable at cnca.gov.cn). In-process inspection at every operation catches issues before they become rejects.
