High‑cycle flip‑top cap moulds engineered for smooth action, 50,000+ cycles tested, tailored for shampoo, lotion, and cosmetic packaging.
Get Flip‑Top Mould QuoteProprietary living hinge geometry, optimized steel grades, and conformal cooling deliver unmatched durability and cycle efficiency.
Precision‑calculated thickness and radius ensure 50,000+ open/close cycles without cracking.
Advanced core design guarantees zero leakage even after repeated use.
Conformal cooling in the hinge area cuts cycle time by up to 20%.
Tailored dispensing holes, matte/gloss textures, and branding options.
Special undercut release mechanism protects hinge during ejection.
High‑toughness steel in hinge slides extends mould life beyond 1 million cycles.
Our engineers use mould flow simulation to optimize hinge thickness and curvature, distributing stress evenly. The result is a hinge that withstands over 50,000 cycles without whitening or fracture.
Dedicated cooling circuits for the hinge area ensure consistent part quality. We use S136 mirror steel for cavities and hardened H13 for sliding components, achieving both aesthetics and durability.

Every flip‑top mould undergoes rigorous hinge endurance and leak tests before shipment.
Automated 50,000 cycle open/close test.
Vacuum / pressure decay test per cap.
CMM inspection on all critical hinge dimensions.
Steel & resin certification provided.
Cracking is usually due to sharp corners, excessive thickness, or poor material flow. We use optimized radii, gradual thickness transitions, and mould flow simulation to eliminate stress points. Our steel selection ensures durability over millions of cycles.
We cover neck finishes from 20/410 to 28/410 for personal care, and up to 38mm for household products. Custom diameters available upon request.
Yes, we have delivered up to 72 cavities for flip‑top caps, with consistent filling and hinge performance across all cavities.
Absolutely. We include a detailed fatigue test report (cycles, torque, visual condition) with every mould shipment.
Standard flip‑top moulds take 35‑45 days. Complex or high‑cavity moulds may require 45‑55 days.
