Mold Design

With over 20 years of engineering experience, our technical team specializes in the design of plastic bottle caps, squeeze bottle caps, and silicone valve caps. Proficient in advanced 2D/3D design software, our engineers possess in-depth knowledge of tooling structures, machining processes, and the material properties of plastics and liquid silicone rubber (LSR).

At the initial review of a product drawing, our engineers can quickly evaluate the optimal mold structure for dispensing caps, flip top closures, and valve-integrated caps. We provide practical tooling proposals that balance shortest lead time, lowest cost, stable production capacity, and dimensional accuracy—without compromising sealing performance or functionality.

Whether it is a standard squeeze bottle cap, a flip top cap with silicone valve, or a highly customized dispensing closure, every design is carefully assessed to optimize tooling strategy, manufacturing efficiency, and long-term production reliability.

Mold Manufacturing

Our in-house tooling facility is equipped with high-precision imported equipment, including Makino CNC machining centers, 5-axis machining, and Sodick EDM systems. All critical mold components are sourced from premium suppliers such as MISUMI and HASCO, ensuring excellent tooling accuracy and repeatability. Whether it is a standard squeeze bottle cap, a flip top cap with silicone valve, or a highly customized dispensing closure, every design is carefully assessed to optimize tooling strategy, manufacturing efficiency, and long-term production reliability.

For projects involving plastic bottle caps, squeeze caps, and silicone valve caps, we strictly control cavity precision, gate design, and valve assembly tolerances to guarantee consistent sealing performance and smooth dispensing. We understand that speed is critical in packaging development. For prototype tooling, we can deliver within 5-7 working days. For production molds used in plastic injection molding or silicone valve molding, our typical lead time is within 45 days, helping customers launch new cap and closure programs on schedule.

Production Management

All production staff undergo systematic training before operating on the shop floor, significantly reducing defect rates in high-volume manufacturing of plastic caps and dispensing closures. Our ERP system enables precise control of raw materials, inventory, and production scheduling—ensuring stable supply while minimizing waste.

Through our Manufacturing Execution System (MES), every step of molding, valve assembly, and cap production is fully traceable. Customers can monitor production status in real time, allowing us to adjust workflows and meet demanding mass production timelines.

We operate multiple specialized workshops, including Class 100,000 medical cleanrooms and optical cleanrooms, enabling us to manufacture both high-end and standard-grade custom plastic bottle caps, squeeze bottle caps, and silicone valve caps according to different industry requirements.

Quality Control

All manufacturing processes strictly comply with ISO22000, ISO9001, and ISO14001 management systems.

In addition to advanced inspection equipment such as CCD full inspection systems and automated visual inspection, our quality engineers conduct rigorous manual audits to ensure that no defective plastic caps or valve components pass through unnoticed.

For each project, our quality team confirms inspection standards with customers in advance and implements them consistently throughout production. Through continuous corrective and preventive actions, we minimize defect risks, maintain stable quality, and deliver reliable, leak-proof, and high-consistency bottle cap solutions—which is why we are trusted by many Fortune 500 customers worldwide.

After-sale Service

We believe that packaging manufacturing is a long-term partnership. Our after-sales service is especially critical for custom plastic bottle caps, squeeze caps, and silicone valve caps. After prototypes are delivered for testing or assembly, we actively collect customer feedback to fine-tune mold design, valve structures, and production parameters. This collaborative approach ensures optimal performance in flow control, sealing, ease of use, and compatibility with filling lines.

The more we communicate, the better we understand your packaging goals. We value every piece of feedback and respond promptly—our sales and engineering teams typically reply within 24 hours to support your project from concept to mass production.
