Trust our over 6 years of expertise and global export experience to elevate your cap production efficiency.
Key Product Features & Technical Specifications
1. Robust Two-Piece Cap Mold Structure
Our mold is designed with a two-piece (cap shell + internal seal liner) configuration, specifically optimized for carbonated drink caps. The split design allows independent cooling and ejection, reducing cycle time while maintaining tight tolerances.
2. 1×16 Cavity High Productivity
With 16 cavities per cycle, this mold offers a balanced output for medium to high-volume production. Each cavity is precision-machined via CNC and EDM to ensure identical cap dimensions, weight (±0.05 g), and concentricity.
3. Advanced Leak-Proof Technology
- Ring groove & ribbed sealing surface – prevents CO₂ escape and liquid leakage.
- Optimized gate position – eliminates flow marks and ensures uniform material distribution.
- Hardened core pins – resist wear from high-pressure injection and repeated opening/closing.
4. High-Grade Materials & Heat Treatment
Standard mold steel options include 1.2344 (H13) or S136, vacuum heat-treated to HRC 48–52. All wear parts (stripper rings, inserts) are DLC-coated for enhanced scratch resistance. The mold base (LKM or HASCO standard) is precision ground to minimize deflection.
5. Efficient Cooling System
Our proprietary conformal cooling channels reduce cycle time by 15–20% compared to conventional straight-line cooling. Each cavity has independent water circuits, maintaining uniform temperature (±2°C) across all cavities.
6. Compatible with Standard Injection Machines
This mold is designed for machines with 150–250 tons clamping force and a standard clamping unit (spacing 460×460 mm). Optional adaptors available for different machines. Gate type: hot runner (single-drop) or cold runner – hot runner recommended for fastest cycles.

Frequently Asked Questions (FAQ)
-
Q: What is the expected mold life for this 1×16 cavity cap mold?
A: Under standard operating conditions (PP material, proper maintenance), our mold can typically achieve 8–10 million cycles before major refurbishment is needed. -
Q: Can the mold be used for non-carbonated drink caps as well?
A: Yes, the leak-proof design is primarily for carbonated drinks, but it also works well for still water and juice caps. We can adjust the sealing ring dimensions per your application. -
Q: What injection machine tonnage is required?
A: A clamping force of 150–250 tons is recommended. The mold's footprint fits standard 460×460 mm tie-bar spacing. We provide machine adaptors if needed. -
Q: Is hot runner included? Can we choose cold runner?
A: Hot runner is optional and recommended for faster cycles. Cold runner (cold sprue) is also available. Please specify when ordering. -
Q: How long is the delivery time?
A: Standard lead time is 35–45 days after confirmation of technical drawings and payment. Rush orders can be arranged (subject to factory schedule). -
Q: Do you provide sample testing or trial runs before shipment?
A: Absolutely. Every mold is trial-run on our in-house injection machine. We send you sample caps and a video of the production cycle for your approval prior to shipping. -
Q: What is your warranty policy?
A: We offer a 12-month warranty on workmanship and materials (excluding wear parts). Spare parts (e.g., core pins, stripper rings) are available at cost. -
Q: Can the cavities be customized to other cap sizes or thread styles?
A: Yes. We can modify cavity geometry for PCO 28, 38, or your custom cap design. Please send your 3D drawing for feasibility review.
