Plastic Refrigerator Shelf Mould

Precision molding guarantee

The Plastic Refrigerator Shelf Mould is specially designed for the inner layer shelves, door bars, and multi-functional storage trays of refrigerators. It is compatible with engineering plastics such as PP, HIPS, and ABS, and can stably adapt to the molding of new materials and high proportion recycled materials. The key mating surfaces have a processing tolerance of ±0.01mm, and the core assembly repeatability positioning error is ≤0.03mm, ensuring that the molded parts precisely fit the internal assembly of the refrigerator.

Efficient Thermal Management

By adopting integrated cooling channels and zone temperature control design, the cooling efficiency has been enhanced by over 25%, directly shortening the molding cycle by 8-12 seconds, significantly increasing the production capacity of a single injection molding machine. Through Moldflow analysis to optimize the channel and cooling layout, problems such as uneven wall thickness and warping in complex structural components are solved, ensuring a high surface finish.

Durability structure design

The core, slider and other easily damaged components are made of P20+Ni pre-hardened steel or hardened steel, with a Rockwell hardness of 48-52 degrees. Combined with self-lubricating guide columns, the wear resistance is enhanced. The Plastic Refrigerator Shelf Mould mold body is made of high-quality steels such as P20H/718, with a stable service life of 500,000 to 1,000,000 times, suitable for long-term mass production.

Reclaimed material adaptation process

To address the issues of poor fluidity of reclaimed materials, high impurity content leading to air bubbles and cracks, etc., the molding process was optimized. The screw compression ratio was adjusted, and the exhaust depth was precisely controlled within 0.04-0.06mm. This effectively suppressed defects and ensured that the quality of the molded parts from reclaimed materials met the standards, thereby saving raw material costs for customers.

Modular Design

The core components of the Plastic Refrigerator Shelf Mould adopt a standardized modular structure. The sliders and ejection system can be quickly disassembled and assembled. The daily maintenance operation is simple and efficient, and the entire process can be completed within 2 hours. The standard configuration includes 1×2 to 1×4 cavity layout. Customization of multiple cavities or stacked molds is available to meet the needs of different production lines. The monthly supply capacity reaches 50 sets.
