ALLWIN MOULD specializes in high-performance two-shot overmold tooling for automotive interior trim parts. This mould is customized for producing automotive instrument dashboard frame (cluster bezel) with soft grain leather texture overmold, meeting strict IATF 16949 automotive manufacturing standards.
Product Overview
This finished component is a car instrument cluster decorative frame, manufactured via two-shot overmolding process:
1. Rigid hard plastic base (ABS/PC/PA66+GF) forms the structural frame, mounting buckles and fixing holes.
2. Soft TPE/TPR material is overmolded on the surface to create leather grain texture, delivering anti-slip touch, shock absorption and premium interior visual effect.
Complex curved contours, integrated positioning clips and hidden mounting bosses are all formed in one mould without secondary assembly.
Core Mould Technical Features
✅ Two-Shot Overmolding System
Shuttle/rotary plate 2K mould structure, independent hot runner systems for hard plastic and soft TPE material respectively
Precision bonding design to avoid delamination between rigid substrate and soft overmold layer, pass automotive aging & adhesion test
Special texture EDM processing on cavity to reproduce realistic leather grain texture consistent with OEM interior requirements
✅ Automotive-Grade Mould Construction
Cavity & core inserts: S136H / NAK80 hardened steel, nitrided treatment, service life 500,000–1,000,000 shots
Mould base follows LKM/HASCO/DME international standards; all standard components adopt HASCO brand
Built-in multi-slide lifter mechanism to demould complex undercut buckles and curved edges without scratching textured surface
✅ Optimized Cooling & Production Efficiency
Conformal water cooling channels + beryllium bronze cooling inserts for thin soft overmold areas
Balanced cooling layout effectively reduces cycle time, prevents warpage and surface sink marks on large curved trim parts
