Customization Process
Applications
Daily wear during lactation, pumping at work (collectors and storage) and formalwear or swimwear (covers). Skin-contact safety matters here, so food-grade or medical-grade compounds can be specified; actual regulatory items and limits rest on reports from qualified third-party laboratories — we support testing but do not issue compliance conclusions.
Process & Certifications
Ultra-thin parts run on LSR injection with mirror-polished cavities, air-assisted ejection and generous draft so the wall is not stretched out of shape. Double-layer shells use two-durometer overmolding: soft inside against skin, firmer outside for support, with a cavity between them that keeps clothing off. Vent holes are cored with fine pins and must be smooth-walled, otherwise they trap residue during cleaning. Nipple covers use low-durometer silicone with a removable adhesive, and the tapered edge is created by the parting line so nothing shows under tight clothing.
Frequently Asked Questions
What conductivity methods do silicone keypads use?+
Three common types: 1) Carbon pill (low cost, 1M cycles); 2) Metal dome (POM, crisp tactile feel); 3) Conductive ink printing (for membrane circuits). Choose based on feel, lifespan, and budget.
Are silk-printed characters on silicone keypads durable?+
Using silicone ink silk-screen + secondary vulcanization, characters resist 500+ alcohol wipes, sweat, and abrasion — 5+ years outdoors without fading.
What is your MOQ and sampling lead time?+
From 50 pcs, small-batch trials supported. Free 1-3 samples (customer pays shipping); sampling 5-7 working days; mass production 15-25 days.
