Technical Infrastructure & Equipment Detail
The core of our high-tech status lies in our specialized machinery. Our Automatic Screw Production Workshop is the heart of our high-volume output, utilizing multi-station cold heading technology to form complex shapes without removing material, ensuring grain flow and superior strength. For the electronics industry, our M1-M3 micro-screws offer the precision required for smartphones and wearable tech.
Our Lathe and CNC Workshop utilizes Swiss-type centering machines and multi-axis machining centers. This allows us to achieve tolerances of 0.006mm, essential for components used in 5G base stations and aerospace sensors. The Stamping Workshop employs high-speed precision presses capable of handling materials from 0.1mm to 5mm thickness, producing everything from simple flat washers to complex progressive-die spring clips.
Quality assurance is bolstered by our Optical Separation Workshop. By using high-resolution cameras and AI algorithms, our optical sorters detect dimensional variances, thread defects, and surface flaws at speeds that manual inspection cannot match. This 100% inspection capability is critical for our partners in the automotive (IATF 16949) and medical sectors where failure is not an option.
Furthermore, our Laboratory serves as an R&D hub. With the X-ray fluorescence spectrometer, we provide certified documentation for environmental compliance, ensuring all products meet the rigorous REACH and ROHS standards required for European and North American markets. Our commitment to de-hydrogenation (hydrogen embrittlement testing) ensures that high-strength fasteners remain ductile and safe under stress.
