With over 7 years of manufacturing experience, a factory spanning 1,000–3,000 square meters, and a dedicated team of 51–100 skilled professionals, we provide turnkey solutions from design to production. Our service includes advanced UG/Parasolid 3D modeling, comprehensive mold protection systems, and seamless robotic arm automation—ensuring your flip-top caps are manufactured with unmatched consistency, speed, and quality.
Whether you need a simple single-cavity mold or a complex multi-cavity hot runner system, our engineering team works closely with you to optimize the design for efficiency and durability. We understand that flip-top caps must meet strict sealing, hinge durability, and aesthetic requirements. Our precise injection molding process, combined with rigorous quality control under the TS16969 standard, delivers caps that perform flawlessly on your production lines.
Key Features & Technical Specifications
- OEM Design Support: We accept UG (.prt) and Parasolid (.x_t) files for direct toolpath generation. No need to convert formats—our engineers work natively with your 3D models.
- Mold Protection System: Every mold is equipped with sensors and pressure monitoring to prevent flash, short shots, and damage, extending mold life by up to 30%.
- Robotic Arm Integration: Automated pick-and-place robots remove finished caps from the mold, reducing cycle time and minimizing human error. Compatible with Fanuc, ABB, and Kuka systems.
- Material Flexibility: Suitable for PP, PE, HDPE, LDPE, and other thermoplastic elastomers. Custom compounds available upon request.
- Precision Tolerance: Achieve ±0.02mm on critical dimensions like snap-fit hinges and orifice diameters.
- Surface Finish Options: SPI A1 to D3 finishes, including textured, glossy, or matte surfaces.
- Quality Assurance: 100% inspection on sealing force, opening torque, and visual defects. TS16969 certified processes ensure repeatability.

Frequently Asked Questions (FAQ)
Q1: What file formats do you accept for mold design?
We accept UG (.prt) and Parasolid (.x_t) files directly. We can also work with STEP, IGES, or STL after conversion. Our team can assist in format conversion if needed.
Q2: How does the mold protection system work?
Our molds are equipped with pressure sensors and cavity temperature monitoring. If abnormal pressure or incomplete filling is detected, the injection machine automatically stops to prevent mold damage. This extends mold life and reduces downtime.
Q3: Can you integrate our existing robotic arm system?
Yes, we can integrate with common robot brands like Fanuc, ABB, Kuka, and Yaskawa. We provide interface programming and end-of-arm tooling design for pick-and-place operations.
Q4: What is the typical lead time for a flip-top cap mold?
For a standard multi-cavity mold, lead time is 25–35 working days. Complex molds with hot runners or unscrewing mechanisms may require 40–50 days. We offer expedited services for urgent orders.
Q5: What materials can you mold for flip-top caps?
Common materials include PP, PE, HDPE, and LDPE. We also support TPE, PA, and ABS. For food-grade or pharmaceutical applications, we can use FDA-approved resins. Material selection is customized to your application.
Q6: Do you provide samples before mass production?
Absolutely. We offer prototype caps from a single cavity trial mold or 3D-printed samples for functional testing. Once approved, we proceed to multi-cavity production molds.
Q7: What quality checks do you perform on flip-top caps?
Our QC includes dimensional inspection using CMM, sealing force test, hinge cycle test (typically 10,000+ cycles), opening torque measurement, visual inspection under bright light, and cap/container fit test. All data is recorded and traceable.
Q8: How do you ensure mold protection during shipping?
Each mold is wrapped in anti-rust paper, vacuum-sealed in plastic, and packed in a wooden crate with shock-absorbing foam. We also coat the mold cavity with rust preventive oil.
