Precision Machining Technology for Moulds & Tools
Our expertise spans CNC turning, milling, grinding, drilling, and EDM, ensuring micron-level accuracy for complex geometries. Utilizing CAM-TOOL software, we generate toolpaths directly from CAD surfaces, eliminating approximation errors and achieving ±0.001 mm precision in high-speed machining7. For optical and automotive headlight moulds, our 5-axis high-speed milling with hyperMILL® strategies optimizes tool tilting angles to avoid collisions while maintaining mirror-like finishes6.
Mould Component Manufacturing
Specialized in critical components:
Punches & Matrices: Hardened with tungsten carbide (HV 1,500+) for extended wear resistance.
Cores & Inserts: Microfabricated core pins for pipette straws down to 0.01 mm diameter, polished to Ra 0.02 μm via non-contact abrasive flow machining18.
Guiding Elements: Integrated with DLC (Diamond-Like Carbon) coatings to reduce friction by 40% in high-pressure die-casting environments4.
Mirror Polishing & Microfabrication
Achieve sub-micron surface finishes through:
Electrochemical Polishing: For eliminating subsurface defects in medical mould components.
Ultrasonic-Assisted Grinding: Reduces edge chipping in ceramic inserts by 60%8.
Non-Abrasive Flow Technology: Ideal for intricate geometries like bottle cap threaded cores, ensuring uniform material removal1.
Integral Mould Development
We design and manufacture moulds for diverse applications:
Injection Moulding: Multi-cavity systems with hot runner optimization, reducing cycle time by 25%10.
Die-Casting: Thin-wall aluminium moulds (0.5 mm thickness) with conformal cooling channels.
Stamping & Cold Heading: Carbide progressive dies achieving 1 million+ cycles without regrinding3.
Gear & Thread Grinding Innovations
Leveraging CNC gear profile grinding and thread grinding technologies from the research of Chongqing University’s State Key Laboratory of Mechanical Transmission:
Precision Gear Machining: Error reduction algorithms minimize tooth flank deviations to ≤3 μm9.
Threaded Core Manufacturing: For bottle blank moulds, utilizing CBN wheels with 80 m/s grinding speeds for Ra 0.1 μm finishes5.
Surface Enhancement Technologies
PVD Coating: Titanium nitride (TiN) and AlCrN coatings enhance hardness to 3,500 HV, extending mould lifespan by 5× in abrasive environments48.
DLC Film Deposition: Corrosion-resistant layers for marine hydraulic components, tested at 5,000-meter depths without degradation4.
Material Expertise
Tungsten Carbide: Machined via wire-EDM with 0.005 mm precision for punch-die clearance control.
Industrial Ceramics: HIP-sintered Si3N4 components with 99.9% density for high-temperature extrusion moulds8.
Industry Applications
Optical Moulds: 5-axis mirror milling achieves λ/4 surface flatness for lens production.
Automotive: Headlight reflector moulds with <0.05 mm wall thickness variations6.
Medical: Microfluidic chip moulds with 10 μm channel accuracy via laser + EDM hybrid machining.
