On August 28, 2025, Chongqing Henghui Precision Mold Co., Ltd. (hereinafter referred to as "Henghui Mold") announced that its independently developed custom-part development process and complete mold set have passed the rigorous inspection of a Brazilian customer. The first batch of products has been packed and shipped to South America. This order further recognizes Henghui Mold's technological strength in high-end custom parts and injects new momentum into China-Brazil precision manufacturing cooperation.
The Brazilian order involves high-strength titanium alloy screw molds for the aerospace industry. The parts require tolerances within ±1μm and must withstand extreme temperature and vibration environments. Henghui Mold's technical team overcame three major technical challenges through a four-step closed-loop process: demand analysis - material matching - process optimization - and full-process quality control. To address the thermal deformation characteristics of titanium alloy, they employed a proprietary cryogenic cutting process, reducing processing temperatures by 30% and ensuring material stability. Leveraging a five-axis machining center and optical inspection equipment, they achieved a mold cavity surface roughness of Ra ≤ 0.05μm, a 40% improvement over the industry standard. Automated production lines and AI-powered quality control systems ensured a dimensional dispersion rate of less than 0.3% for each batch of 100,000 parts, meeting the stringent "zero defect" requirements of Brazilian customers.
"The core of non-standard parts lies in customization, but customization doesn't necessarily sacrifice efficiency," said Mr. Li, Henghui Mold's Technical Director. "Using a modular design platform, we've reduced the mold development cycle from the traditional 60 days to 35 days, while maintaining a yield rate exceeding 98%."
This Brazilian order is not Henghui Mold's first overseas expansion. On August 20, 2025, the company completed delivery of its independently developed high-end CNC parts processing machine to a Russian customer, marking a milestone in its high-end equipment exports. Just one week later, a Brazilian order was placed, further demonstrating Henghui Mould's global strategy of "technology-driven + localized service." The company's five-axis machining center achieves micron-level accuracy (±2μm), and its dynamic demonstration system garnered attention from representatives of companies from multiple countries at the 2025 Vietnam International Industrial Exhibition. A technical service center has been established in Brazil, staffed by a multilingual team of engineers, providing 24/7 on-site support to alleviate customer concerns. A long-term partnership has been established with a supplier to a Brazilian aviation industry company to ensure seamless integration of raw material supply and process standards.
"The Brazilian market's demand for precision parts is growing at an annual rate of 15%, but local supply capacity is insufficient," said Hou Hui, General Manager of Henghui Mold. "Our advantage lies in providing a 'Chinese solution' that meets international standards while reducing customers' overall costs through localized services."
Since its founding, Henghui Mold has focused on the micro screw market, building a comprehensive product portfolio covering sizes from M0.5 to M3, using over 12 materials, including titanium alloys, stainless steel, and carbon steel. These products are widely used in high-end industries such as aerospace, medical devices, and precision electronics. Its core competitiveness stems from three pillars: One patent and four international certifications ensure industry-leading five-axis machining technology; ISO 9001:2025 quality management system certification ensures full traceability from raw materials to finished product; and the company currently has strategic partnerships with over 50 high-end equipment companies worldwide, achieving a customer repurchase rate exceeding 85%.
"There are no shortcuts in precision manufacturing; the only way is to persist in long-termism," said Hou Hui, general manager of Henghui Mould. "In the future, we will continue to use micron-level precision as the cornerstone to promote the upgrade of 'Smart Manufacturing in China' to 'Precision Manufacturing in China', and provide better solutions for global customers."
