Refrigerator Freezer Drawer Injection Mold

Integrated One-Step Molding: Engineered for high-efficiency production of refrigerator freezer drawers, completing molding, core pulling, ejection, cooling, and gate trimming in a single automated cycle.
Full-Series Compatibility: Suitable for all structural drawer components across different freezer capacity specifications and door matching designs.

Corrosion-Resistant Steel: Utilizes premium corrosion-resistant tool steels such as S136 and 2316, offering superior wear resistance and erosion resistance.
High Polish & Hardness: Quenched to HRC 48–52 with mirror-finish polishing up to SPI A2 grade, ensuring smooth optical clarity for transparent drawers.
Extended Service Life: Total mold service life reaches ≥ 800,000 shots (up to 1,000,000 shots under optimal low-temperature operating maintenance).
