Quality Essentials of Automotive Interior Parts Moulds
To ensure long‑term reliability of automotive interior parts moulds and high injection moulding yield, SINOMOULD strictly controls the following quality essentials:
- Material Selection & Heat Treatment: Use of high‑quality pre‑hardened steel, corrosion‑resistant steel, and beryllium copper alloy, combined with vacuum quenching and cryogenic treatment, to improve mould wear resistance and fatigue strength.
- Precision Assembly & Tolerance Control: Using CMM and blue light scanning technology to ensure assembly gap between mould components ≤0.02 mm, avoiding sink marks, flash, and other defects.
- Surface Quality & Texture Consistency: Through EDM finishing and chemical etching processes, achieve uniform grain, gloss, and tactile feel, meeting the high‑sensory requirements of automotive interiors.
- Cooling & Venting System Optimization: Design conformal cooling channels and proper venting slots to shorten cycle time, prevent gas entrapment and burning, and ensure clean appearance of interior parts.
- INS Mould Quality Essentials: For in‑mould decoration (INS) process, SINOMOULD strictly controls the accuracy of the film positioning groove and uniformity of vacuum suction, ensuring no film wrinkling after clamping and injection pattern position deviation ≤0.1 mm, meeting high‑quality interior requirements.
Machining Essentials of Automotive Interior Parts Moulds
To achieve high efficiency and high precision in manufacturing automotive interior parts moulds, SINOMOULD adopts the following core machining essentials:
- Full Digital Mould Design: Using UG/NX, CATIA for 3D modeling, and optimizing gate location, runner balance, and deformation through Mouldflow analysis in advance.
- 5‑Axis CNC & Wire EDM: High‑speed 5‑axis milling for complex curved surfaces (e.g., instrument panel skin textures), combined with wire EDM to ensure dimensional consistency of precision structures such as sliders and lifters.
- Multi‑process Surface Finishing: Providing polishing, sandblasting, chrome plating, or laser etching as needed to improve mould release performance and product texture.
- Strict Mould Trial & Validation Process: Multiple rounds of injection parameter debugging in our in‑house trial workshop, followed by dimensional inspection, environmental aging tests, and CMF matching verification, ensuring stable mass production.
- INS Mould Machining Essentials: Precision CNC machining of film positioning frames and vacuum suction grooves with surface roughness Ra ≤0.4 μm, optimizing gate location and hot runner temperature control to prevent film flushing and ensure perfect bonding of decorative layer with plastic.
