Refrigerator Door panel Injection Mold Refrigerator Door Body Injection Mold
1.Product Introduction
Kaihua Moulds provides high quality refrigerator door panel molds for global home appliance manufacturers. These molds are engineered to meet the technical requirements of large door panel production and to ensure consistent, high standard output.
Large door panels feature long melt flow paths that often lead to uneven filling. To address this, our molds apply material suited hot runner systems verified through CAE flow simulation. This approach helps maintain stable melt delivery throughout the cavity and reduces filling defects such as edge shortage or localized material buildup.
Surface quality is a critical requirement for exterior refrigerator components. To minimize sink marks at areas with changes in wall thickness, our cavity and core structures are designed in line with material shrinkage behavior, supporting smooth and clean molded surfaces without relying on post processing corrections.
Cooling performance has a direct impact on deformation and dimensional accuracy. Our zoned cooling channel layout is designed to correspond to the heat distribution of different door panel regions. This helps maintain uniform cavity temperatures and reduces the risk of warpage, ensuring the mold can consistently produce door panels within specification.
Key functional areas such as hinge mounts and magnetic seal slots require tight tolerances. We control these dimensions through dedicated precision machining and inspection processes during mold manufacture, supporting accurate molding of structural features required for downstream assembly by the customer.
To support long term production, our refrigerator door panel molds are built with durable materials and modular wear components that can be serviced or replaced efficiently. All mold designs are compatible with mainstream injection equipment, allowing customers to integrate our molds into existing production lines with minimal adjustment and stable operating performance.
In addition to refrigerator molds, we also manufacture various home appliances injection molds such as washing machine molds, coffee machine molds, air conditioner molds.
