Key Mold Design Challenges

Highly balanced runner and cooling system across 64 cavities: Ensures uniform filling and consistent shrinkage to minimize variations in pump head dimensions and weight.
Demolding of complex micro-features: The part integrates internal threads, sealing tapers, snap-fit features, and micro-fluidic channels, requiring high-precision sliders, lifters, or unscrewing mechanisms.
Stringent appearance and functional requirements: Visible surfaces must be mirror-finished with no weld lines or sink marks; critical sealing areas require tight tolerances of ±0.01–0.02 mm.
Compatibility with fully automated production: Mold and part design must support robotic part removal, automatic gate degating, and synchronization with high-speed filling line cycles.

Typical Application Industries

Daily chemical products (shampoo, body wash, hand soap)
Skincare and cosmetics (lotion, serum, sunscreen)
Household cleaning (disinfectants, dishwashing liquid, fabric softener)
Medical and hygiene consumables (alcohol-based hand sanitizers, pharmaceutical dispensing bottles)
