SHENZHEN, China, Sept. 30, 2026 /PRNewswire/ -- Shenzhen MaiJin Metal Works Co., Ltd. (MAIJIN Metal), a specialized manufacturer of CNC machining parts, has resolved a critical production capacity bottleneck for a 600,000-unit component order. By shifting from traditional machining to a composite manufacturing process, the company increased overall processing efficiency by 50%.

Process Innovation Boosts Production Efficiency by 50%

The component initially relied entirely on a pure CNC lathe turning process. Due to a large stock allowance on the blank, machining a single unit required approximately three minutes. Processing the full 600,000-unit batch would have consumed over 30,000 machine hours, a timeline incompatible with the client's urgent delivery requirements.

MAIJIN Metal's engineering team implemented a "cold heading pre-forming + CNC precision machining" solution. Workpieces are rapidly formed to near-net shape via cold heading in seconds, followed by finishing on CNC lathes to achieve micron-level tolerances.

Following client approval and successful sample validation, the new process entered full mass production. This approach minimizes CNC stock removal and makes the most of cold heading's strengths in high-volume, efficient forming, boosting overall processing efficiency by 50%. That effectively cleared the capacity bottleneck for the 600,000-piece order and ensured on-time delivery.

Highlighting the win-win outcomes of this collaboration, the client awarded MAIJIN Metal a Certificate of Excellence, noting: "You are recognised based on excellence achieved in the areas of quality, service and value added."

"At MAIJIN Metal, we do not just manufacture parts; we engineer solutions," said Daniel Xian, General Manager at MAIJIN Metal. "Innovating machining processes to overcome capacity constraints is exactly what our engineering team excels at. We thrive on taking on challenging projects and delivering tangible cost and time savings for our global partners."

20 Years of Precision Manufacturing Expertise

With nearly 20 years of CNC machining experience, MAIJIN Metal operates a 3,000-square-meter production facility equipped with 80 CNC machines, including advanced five-axis CNC machining centers.
