Upper Volute Housing Injection Mold

Integrated Precision Injection Molding: Engineered for high-efficiency production of upper volute housings, completing molding, core pulling, ejection, cooling, and gate trimming in a single automated injection cycle.
Full-Series Structural Compatibility: Suitable for upper volute housing components across all systems, including air conditioners, fresh air ventilation systems, and industrial blowers.
Full-Scenario Applications: Widely applicable in automotive air conditioning, residential HVAC, ventilation systems, and fluid movement equipment.

Corrosion-Resistant Tool Steel: Built with premium corrosion-resistant tool steels such as S136 and 2316, delivering exceptional wear resistance and anti-corrosion performance.
High Polish & Hardness: Quenched to HRC 48–52 with mirror polishing capability up to SPI A2 grade, ensuring precise internal flow channels and surface quality.
Long Operating Lifespan: Engineered for a standard mold service life of ≥ 800,000 shots under standard maintenance.
