1. Core Mold Optimizations: Eliminate Assembly Tolerances & Molding Flash
- High-precision CNC Machining & Mirror Polishing
Ultra-precise CNC machining is applied to all track joint surfaces during mold development to minimize assembly tolerances. All mold cavities undergo mirror polishing to produce flawlessly smooth inner track walls after molding, erasing frictional resistance at the physical source.
- Optimized Venting & Gate Layout
Insufficient mold ventilation or improperly positioned gates easily lead to incomplete filling and excess flash at joint areas. Scientifically designed vent grooves and runners balance molten plastic flow during injection, preventing residual plastic buildup along seams.
- Precision Anti-Offset Tenon-and-Mortise Locating Structure
Custom male and female interlocking positioning components are integrated into molds. They enable seamless fitting between separate track sections after demolding and eliminate stepped misalignment caused by assembly tolerance errors.
2. Coordinated Materials & Processes to Sustain Long-Term Dimensional Stability
- Scientific Cooling Channel Layout
Optimized internal cooling circuits deliver consistent cooling speed across all track segments, eliminating internal stress and warping deformation caused by uneven thermal expansion and contraction.
- Low-Shrinkage, High-Wear-Resistant Engineering Plastics
We adopt premium engineering plastics with ultra-low shrinkage and outstanding abrasion resistance, paired with calibrated injection holding pressure parameters. Track joints retain original smoothness and dimensional stability even under long-term, high-frequency ball friction.
