Mould Technical Highlights

Leveraging over 20 years of technical expertise and more than 100 patents, SINOMOULD has built an industry‑leading system of mould technical highlights centered on four pillars: mould quality inspection, mould R&D, mould service, and enterprise equipment. Each highlight directly translates into customer‑perceivable benefits: longer mould life, shorter cycles, and fewer defects.

Mould Quality Inspection

Mould quality is the foundation of moulding stability. SINOMOULD integrates quality inspection throughout the entire process of design, machining, assembly, and mould trials, forming the following technical highlights:

  • Non‑destructive testing capability: Ultrasonic flaw detection and magnetic particle inspection to identify internal micro‑cracks in mould cores.
  • Material spectral analysis: Ensures that the grade and composition of mould steel meet design specifications, preventing material mixing.
  • Trial center validation: Equipped with injection moulding machines from multiple brands (130T – 6000T) to simulate customer production conditions, delivering trial reports and process parameters.

This quality inspection highlight ensures a “first‑time‑qualified delivery rate” exceeding 98%.

Mould R&D

SINOMOULD’s own Plastics Technology R&D Studio has been granted over 100 patents covering mould structures, plastic part inventions, and process improvements. R&D technical highlights include:

  • European advanced processes: Gas‑assist / water‑assist moulding, high‑gloss injection moulding, stack moulds, multi‑color injection moulding, foam injection moulding.
  • Microcellular foam mould technology: MuCell‑grade micro‑cells (10–50 μm), weight reduction 10–25%, warpage reduction 50–80%.
  • Magnesium‑aluminum alloy semi‑solid injection technology: Semi‑solid die casting, mould life increased 2–3 times, porosity reduced by over 50%.
  • Combined mould flow and structural simulation: Optimizes gate, cooling, and ejection systems in advance, reducing the number of trial shots.

These R&D highlights place SINOMOULD among the top mould manufacturers in China and have earned recognition from European partners through technical consulting.

Mould Service

Technical advantages must translate into service experience. SINOMOULD’s mould service technical highlights cover the whole process from requirement analysis to mould retirement:

  • DFM (Design for Manufacturability) report: Detailed product optimization suggestions before mould construction, reducing downstream modification costs.
  • One‑stop project management: Single point of contact for mould design, machining, trials, and batch delivery.
  • Global after‑sales support: Response within 24 hours; mould repair, refurbishment, spare parts replacement, and off‑site trial guidance available.
  • Technical training: Professional courses on mould maintenance and injection process tuning for customer teams.

Through this service highlight, SINOMOULD helps customers shorten project launch cycles by 30%.

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.

Mould Equipment

Advanced mould processing equipment is the physical guarantee of design accuracy. SINOMOULD’s equipment suite includes 5‑axis CNC, mirror EDM, wire EDM, precision grinders, and a constant‑temperature workshop.

All enterprise equipment is integrated into a digital management system (DNC), enabling online program transmission and real‑time status monitoring. This equipment highlight ensures that SINOMOULD can reliably machine high‑difficulty moulds for the automotive, medical, and electronics industries.
