Main Application Areas of Large Injection Molds

Large injection molds typically refer to molds weighing over 2 tons, or those compatible with injection molding machines with a clamping force of over 6300kN and an injection volume of over 3000cm3. Their design, manufacturing, and application must meet core requirements such as high strength, high precision, complex structures, and high-efficiency production. The following is a breakdown of their application areas:

1. Automotive Industry: Used to produce complex components such as bumpers, grilles, headlight brackets, dashboards, and interior panels. They are a core supporting tool for the modern automotive trend towards lightweighting and modularization. For example, automotive bumper molds utilize a two-plate mold structure, combined with hydraulic cylinder core-pulling and hydraulic cylinder wedge clamping technology, to meet the molding requirements of large injection molded parts.

2. Daily Necessities Industry: Emphasizing multi-cavity design, rapid cycle time, and high mold durability, these molds are widely used for everyday items such as cups, buckets, storage boxes, tableware, chairs, and trash cans. For example, large molds can achieve simultaneous molding of large sizes and multiple cavities, producing multiple standardized parts in a single injection, meeting the massive demands of the daily necessities industry.

3. Home Appliance Industry: Injection molds require high precision in dimensions, surface finish, and structural fit, among other aspects. Applications include refrigerators, air conditioners, televisions, washing machines, and rice cookers. For example, home appliance injection molds utilize high-gloss surface treatments to ensure transparent parts (such as panels and windows) have a good gloss.

4. Logistics Industry: This industry has extremely high requirements for the load-bearing capacity, impact resistance, and durability of injection molded parts. Typical injection molded parts include plastic pallets, turnover boxes, logistics baskets, and collapsible storage boxes. For example, large logistics molds use a modular, insert-based structure to optimize mold thermal balance and extend mold life.
