As a professional manufacturer with over 6 years of precision mold experience, Changzhou Hongxinyutai Precision Mold Co., Ltd. proudly presents our Hydraulic Driven Plastic Mold for Threaded Bottle Caps (PP/PE) with Mold Protection. This mold is engineered to deliver high-cycle efficiency, consistent cap quality, and extended tool life—making it the ideal solution for high-volume cap production lines. Our factory, spanning 1,000–3,000 square meters and staffed by 51–100 skilled workers, ensures every mold meets rigorous quality standards under TS16969 certification.
Key Features & Technical Specifications
- Hydraulic Driven Core Pulling Mechanism – Ensures reliable and smooth ejection of threaded caps, minimizing cycle time and reducing wear on moving parts.
- Integrated Mold Protection System – Sensors and mechanical safeguards prevent damage from overloading, misalignment, or material blockage, significantly reducing downtime.
- Optimized for PP/PE Materials – Precise cooling channel design and gate positioning ensure uniform shrinkage, excellent dimensional stability, and high gloss finish on caps.
- Multi-Cavity Capability – Available from 4 to 32 cavities (or more upon request) to match your production capacity needs.
- Durable Construction – Made from premium alloy steel (P20, H13, or equivalent) with heat treatment and surface hardening for long service life.
- Stripper Plate & Unscrewing Design – Efficient unscrewing mechanism for threaded caps, with optional servo-driven or hydraulic unscrewing.
- Compatible with Standard Injection Molding Machines – Can be adapted to various hydraulic and hybrid machines with standard mounting patterns.
- Low Maintenance – Self-lubricating bushings, hardened guide pins, and easy-access components reduce maintenance frequency.

Frequently Asked Questions (FAQ)
-
Q: What materials are suitable for this mold?
A: The mold is specifically designed for PP (polypropylene) and PE (polyethylene). It can also be adapted for other thermoplastics like PET or nylon upon request, but for best results, we recommend using PP/PE as per the original design. -
Q: How does the mold protection system work?
A: The system includes pressure sensors, limit switches, and a mechanical overload clutch. If abnormal conditions (e.g., stuck mold, high pressure) are detected, the machine automatically stops or reverses to prevent damage. This protects both the mold and the injection machine. -
Q: What is the typical lead time?
A: Standard lead time is 30–45 days from order confirmation, depending on cavity count and complexity. Urgent orders can be expedited – please contact us for details. -
Q: Can you provide molds with different cavity numbers?
A: Yes, we offer customizable cavity numbers from 2 to 48. We can also design family molds for different cap sizes. Please specify your required output per hour for optimal cavity configuration. -
Q: Do you offer after-sales technical support?
A: Absolutely. We provide lifetime technical support, including installation guidance, troubleshooting, and spare parts supply. Our team is available via email, phone, or video call. -
Q: What is the warranty period for this mold?
A: We offer a 12-month warranty (or 1 million cycles, whichever comes first) for defects in materials and workmanship. Extended warranty options are available. -
Q: How is the mold shipped?
A: We use professional wooden crates with shock-absorbing padding. The mold is shipped FOB from Jiangsu, Shanghai, or Shenzhen ports. We can also arrange door-to-door delivery if needed. -
Q: Can I test the mold before purchasing?
A: Yes, we welcome customers to visit our factory in Changzhou for mold trial runs. Alternatively, we can provide video recordings of the mold running on our injection machines. Samples can be sent for your evaluation.
