Mould Processing Equipment

SINOMOULD is equipped with a world‑class fleet of mould processing equipment, covering the entire workflow from rough machining and finishing to surface treatment. By combining high‑precision, high‑stability machines, we ensure that dimensional tolerances for every mould are controlled within ±0.005 mm, delivering reliable and durable injection moulding solutions to our customers.

5‑Axis CNC Mould Processing Equipment

The 5‑axis simultaneous machining center is one of SINOMOULD’s core assets. We have introduced German DMG MORI and Japanese Makino 5‑axis machines, enabling complete machining of complex curved surfaces, deep cavities, and undercuts in a single setup.

  • Machining accuracy: Positioning accuracy ±0.003 mm, repeatability ±0.002 mm
  • Advantage: Reduces datum conversion errors, shortens machining cycles by over 30%
  • Applications: Large automotive moulds, multi‑cavity medical moulds, complex structural parts for home appliances

These high‑precision 5‑axis CNC machines secure SINOMOULD’s leading position in high‑end mould manufacturing.

Mirror EDM Mould Processing Equipment

For features such as deep narrow slots, sharp corners, and fine textures that cannot be directly CNC milled, SINOMOULD uses Swiss GF AgieCharmilles and Japanese Mitsubishi mirror EDM machines. Our EDM equipment offers:

  • Surface finish: Up to Ra 0.1 μm, no subsequent polishing required
  • Electrode wear: Intelligent pulse control, wear rate <0.1%
  • Automation: Equipped with tool magazines and automatic tool changers, supporting unattended night shifts

With mirror EDM equipment, we achieve extreme detail in mould cavities, meeting high‑transparency and high‑surface quality requirements for optical lenses, microfluidic chips, and more.

Wire EDM (Wire‑Cut) Mould Processing Equipment

The machining of irregular holes, tapers, and micro inserts in precision stamping and injection moulds relies on the wire EDM process. SINOMOULD has installed Japanese Sodick and Mitsubishi wire EDM machines, forming an efficient, low‑consumption wire‑cut equipment group.

This wire EDM equipment can reliably machine micro‑holes of φ0.2 mm and narrow slots as small as 0.02 mm wide, providing a solid guarantee for precision multi‑cavity moulds.

Precision Surface & Optical Profile Grinding Equipment

The final accuracy of flatness, perpendicularity, and contoured profiles of mould components depends on grinding processes. SINOMOULD’s grinding equipment includes:

  • German Blohm precision surface grinder: flatness up to 0.002 mm / 1000 mm
  • Japanese Waida optical profile grinder: 20–50× projection magnification for profile grinding of forming punches and inserts
  • Swiss Studer cylindrical grinder: micron‑level machining of ejector pins, sleeves, and other cylindrical parts

These grinding machines elevate the parallelism and surface finish of mould plates and inserts to mirror‑like levels, significantly extending mould life.

CMM & Vision Measurement Equipment (Quality Closed‑Loop)

First‑class machining demands rigorous inspection. SINOMOULD has established a metrology lab equipped with inspection equipment that matches the machining accuracy:

  • ZEISS bridge‑type CMM: measuring range 1200×1000×800 mm, accuracy 0.9+L/350 μm
  • Keyence high‑precision vision measurement system: capable of measuring small contours, angles, and radii
  • Roughness tester, contour tester, hardness tester – full‑process control

All parts produced by our mould processing equipment must pass a full dimensional report from CMM or vision measurement, ensuring “first‑trial‑qualified” moulds.

Why Is SINOMOULD’s Equipment Portfolio More Trustworthy?
