Polypropylene Plastic Air Cooler Door Panel Mould Injection Molding Fire Proof ODM
ALLWIN MOULD is a leading manufacturer of engineering-grade plastic injection moulds, specializing in custom tooling solutions for refrigerator door panels, liners, and structural components. Engineered to meet the rigorous demands of global home appliance OEMs, our refrigerator door moulds deliver exceptional dimensional accuracy, superior surface finish, and long-term durability for high-volume mass production.
Product Overview
This is a large-scale, high-precision injection mould purpose-built for manufacturing refrigerator door shells, liners, and integrated door handle components. Designed to produce complex, large-format plastic parts with precise reinforcement ribs, mounting brackets, and functional cutouts (as shown in the image), the mould ensures flawless part consistency, minimal warpage, and a service life of 500,000 to 1,000,000+ shots. It is specifically engineered for energy-efficient refrigerator door designs, including side-by-side, French door, and bottom-freezer configurations.
Key Technical Specifications & Features
✅ Advanced Cooling System for Large Format Parts
Equipped with a comprehensive network of water cooling channels and high-efficiency Beryllium Bronze cooling inserts strategically placed across the mould surface. This ensures uniform temperature distribution, minimizes cycle time, and eliminates warpage common in large refrigerator door panels, guaranteeing dimensional stability for every production run.
✅ Automotive-Grade Mold Construction
- Mold Base Standards: Compliant with international standards (LKM, HASCO, DME) for global interchangeability and easy maintenance.
- Premium Tool Steels: Manufactured using high-quality steels such as 718H, S136(H), and NAK80 to ensure superior wear resistance and a long mould lifespan.
- Hot Runner System: Features an advanced hot runner injection system for zero-waste, high-efficiency filling, reducing material costs and post-processing requirements.
✅ Complex Undercut & Ejection Mechanisms
Incorporates precision hydraulic/slider ejection systems and dedicated actuators to handle the complex geometry of refrigerator doors, including integrated handle recesses, hinge pockets, and sealing grooves. This design ensures smooth, damage-free ejection of large, delicate components.
✅ High-Efficiency 排气 & Temperature Control
Equipped with a sophisticated vacuum isolation layer and heating/cooling dual systems to precisely control melt temperature during injection. This eliminates common defects such as surface flow marks, weld lines, and color variation, ensuring a premium surface finish on every part.
✅ Material Compatibility
Optimized for high-performance home appliance thermoplastics, including ABS, PP, PC, and PS. The mould is fully compliant with RoHS, UL, and custom material safety standards as required by international customers.
