Description

Specializing in high-precision insert injection molds, we deliver turnkey solutions for complex multi-material components requiring metal-plastic integration. Our German-designed mold shop combines Röders RP five-axis machining centers with AgieCharmilles EDM technology, achieving micron-level accuracy for medical devices, automotive connectors, and micro-electronics packaging.

Core Technical Capabilities:
• Insert Molding Expertise: Overmolding of brass terminals, ceramic substrates, and PCB assemblies with ±0.02mm positional accuracy
• Micro-Mold Manufacturing: Gates down to 0.1mm for microfluidic chips and connector pins
• Conformal Cooling: 3D printed cooling channels following cavity contours (40% cycle time reduction)

Advanced Engineering Process:

  1. Design Phase:

    • Moldflow analysis for warp prediction and gate optimization

    • DFM reports with draft angle and wall thickness recommendations

  2. Precision Machining:

    • Hard milling (HRC 62) with <1μm surface roughness

    • Coordinate grinding for slide fits <0.003mm clearance

  3. Validation:

    • Optical comparators for profile verification

    • Trial shots with CMM inspection reports

Material-Specific Solutions:

  • Engineering Plastics: PEEK, PEI (Ultem®), PPSU molds with hardened cores

  • Liquid Silicone Rubber (LSR): Cold runner systems with vacuum venting

  • Bio-Polymers: FDA-compliant tooling with easy-demold features

Industry Applications:
✓ Medical: Overmolded surgical instruments with embedded RFID tags
✓ Automotive: Waterproof connectors with integrated seals (IP68)
✓ Consumer Electronics: Thin-wall housings (<0.4mm) with metalized logos
✓ IoT Devices: Antenna integration through in-mold labeling

Quality Assurance Protocol:

  • Steel certification: Traceable mill test reports

  • Tool tryout: 3-stage sign-off (T0/T1/T2)

  • Production monitoring: Cavity pressure sensors

  • Documentation: Full PPAP packages available

Technical Advantages:
• Zero-sink marks through sequential valve gating
• Automatic insert feeding systems for high-volume production
• Collapsible cores for internal undercuts
• Quick-change insert systems for family molds

Value-Added Services:

  • Free material selection consultation

  • Rapid prototype molds (5-7 days) for design validation

  • In-house injection molding production (50-650 ton presses)

  • Mold maintenance programs with digital health monitoring
