Bottle cap molds play a vital role in mass production packaging lines. With advanced manufacturing technology and strict quality control, a well-designed cap mold ensures consistent product quality, reduced downtime, and high return on investment.

We exclusively use premium corrosion-resistant stainless steels such as Assab S136 (Sweden) and Groditz M340 (Germany). Combined with deep vacuum nitriding, surface hardness exceeds HV1000°, with mirror polishing up to Ra≤0.015μm. We guarantee a mold life of over 3 million shots.
Standardized with our in-house developed pneumatic valve gate hot runner system. Multi-zone independent temperature control keeps fluctuation ≤±1℃, preventing material degradation. The gate is automatically sealed after injection, creating a "gate-cut-free" preform that requires no manual trimming — achieving true zero-waste production.
Our 3D conformal cooling channels, designed based on ANSYS simulation, eliminate hot spots and increase cooling efficiency by over 30%. By optimizing the mold structure and injection process, we achieve an injection cycle time of under 10 seconds, significantly boosting your production capacity.
Perfectly compatible with major global injection molding machine brands: HUSKY, NETSTAL, SACMI, KRONES, DEMAG, and all major Chinese manufacturers. Standard interface design for plug-and-play operation.
