01 Why precision tolerance matters

For watch movements, even a deviation of a few microns can cause friction, timing errors, or premature failure. Our micro precision steel shafts are ground to tight tolerances (as low as ±0.001mm) using multi-axis CNC lathes. This same level of accuracy applies to our precision turned parts for automotive sensors and electronic actuators. We also produce custom locating pins and precision ground shafts that ensure smooth rotation and alignment in automation equipment. By controlling every step from material selection to final inspection, we eliminate the risk of out-of-spec components disrupting your assembly line.

02 How brass nuts improve plastic parts

Brass insert nuts offer superior pull-out resistance and thermal conductivity compared to other threaded inserts. When molded into plastic housings for consumer electronics, our press-fit nuts create durable threads that withstand repeated assembly and disassembly. Unlike self-tapping screws, brass press-fit nuts for plastic injection molding do not stress the surrounding material, preventing cracks and creep. For sensor and electronic equipment manufacturing, we also provide copper insert nuts and stainless steel fasteners that enhance reliability in high-vibration environments. Our custom brass parts are available with various platings to resist corrosion.

03 Custom CNC for any volume

Whether you need 100 prototype shafts or 500,000 high-volume production of custom hardware, our production capabilities adapt seamlessly. We handle small-batch custom orders for medical device applications and large-scale runs for automotive fasteners. Our CNC turning services produce custom precision sleeves, industrial bushings, and custom metal components from materials like stainless steel, aluminum, bronze, and copper. For self-lubricating bronze bushings used in industrial machinery, we ensure consistent porosity and dimensional accuracy. All custom CNC machined parts undergo rigorous quality testing, including CMM inspection and material certification.

04 Fast delivery for global buyers

A common pain point in sourcing custom precision parts is unreliable delivery schedules. We maintain strategic stock of raw materials and use efficient production planning to achieve fast lead times—typically 10-15 days for prototypes and 3-4 weeks for mass production. Our quality control processes include in-process inspections and final dimensional reports shipped with every order. For international clients, we offer flexible shipping options and full traceability. This commitment has made us a trusted partner for companies in robotics, telecommunications, and aero industriesspace where component failure is not an option.
