In chemical and energy storage industries, a lid is never just a lid. For electrolyte containers, the secondary lid plays a vital role in sealing integrity, safety, and leakage prevention — especially when handling sensitive or hazardous liquids.
To meet these demands, manufacturers are moving toward two-material (2K) injection moulding, combining rigid structure with flexible sealing in one integrated solution.
At YUEYI MOULD, we engineer two material secondary lid moulds that ensure reliable sealing performance, chemical resistance, and production consistency.
