High-Precision Injection Tooling Technologies
From prototype tooling to multi-cavity production molds, we engineer injection tooling that satisfies strict dimensional tolerances and fast cycle times.
Multi-Cavity High-Efficiency Production Molds
Our multi-cavity plastic injection molds are engineered to maximize productivity and lower cost per unit. Built with balanced hot runner feed systems and optimized conformal cooling lines, our molds maintain uniform melt temperature and equal filling pressure across all cavities, preventing flash, sink marks, or dimensional variance.
- High-cavitation tooling setups (4 to 32 cavities) for high-volume series
- Equipped with premium hot runner systems for runnerless zero-waste production
- High-speed cycle times achieved via precision conformal cooling channel layouts
- Ideal for electronic housings, plastic enclosures, gears, and structural clips
Custom Insert & Overmolding Plastic Tooling
We specialize in manufacturing complex plastic injection molds for insert molding and multi-shot overmolding. Whether encapsulated metal threaded inserts, structural pins, or soft-touch elastomeric grips over rigid plastic frames are required, our precision mold shut-offs and mechanical slider mechanisms guarantee tight alignment without flashing.
- Precision slider and lifter mechanisms for complex internal undercuts
- Zero-flash shut-off steel design around metallic inserts and electrical pins
- Compatible with engineering polymers including PA66, PC, POM, and ABS
- Extends part durability by eliminating secondary assembly operations
Hardened Tool Steels & Polymer Compatibility
Selecting the proper mold core steel and calculating precise polymer thermal contraction is critical to long mold life and repeatable dimensional accuracy.
Premium Tool Steels
Fabricated using high-grade P20, H13, S7, or NAK80 hardened steels for millions of molding cycles without fatigue.
Exact Shrinkage Compensation
CAD cavities adjusted for polymer-specific volumetric shrinkage factors across engineering thermoplastics.
Mirror Cavity Polishing
SPI A2/A3 diamond polishing and chrome plating ensure flawless surface finish and effortless part release.
Conformal Cooling Channels
CNC drilled and optimized cooling circuits minimize cycle time and eliminate thermal warping.
Our 6-Step Injection Mold Manufacturing Lifecycle
A controlled engineering lifecycle from 3D CAD design validation to final press trial inspection.
DFM & Moldflow Analysis
Evaluating draft angles, wall uniformity, gate placement, and plastic flow behavior in CAD.
Steel Preparation & CNC
High-speed 5-axis CNC cavity milling, plate squaring, and cooling line drilling.
EDM Spark Erosion
Wire EDM and sinker erosion for sharp internal corners, ribs, and fine textured surfaces.
Assembly & Press Trial
Precision fitting of core/cavity plates, ejector pins, hot runners, and T1 trial injection runs.
