3. Core Advantages

  1. S136 HRC48-52 Injection Mold Superiority: S136 anti-rust stainless steel with HRC48-52 hardness features outstanding wear & corrosion resistance. Polished cavity ensures smooth cap surface with no scratch or sink mark, effectively lowering molding reject rate.

  2. 1×8 Multi-Cavity High Efficiency Design: 8 identical cavities on one set of injection mold, 8 caps produced per shot, greatly shorten molding cycle and cut down unit production cost for large bulk orders.

  3. Virgin LDPE Molding Performance: LDPE material brings good flexibility, impact resistance and excellent sealing property for plastic caps, widely suitable for daily chemical, food & beverage packaging closure.

  4. Full Customization Support: We design & manufacture injection mold strictly based on your 2D/3D drawings or physical cap samples, adjustable cap size, thread structure and mold cavity layout as customized demands.

4. Application Range of LDPE Plastic Cap

  • Food packaging: beverage bottle, yogurt jar sealing cap

  • Daily chemical: shampoo, hand wash, lotion plastic closure cap

  • Medical small container, cosmetic trial bottle end cap

5. Custom Molding Working Flow

  1. Customers provide drawing/sample → 2. DFM analysis & injection mold structure design →3. CNC/EDM mold processing + cavity polishing for S136 steel →4. Mold assembly and pre-test →5. LDPE trial injection & sample confirmation →6. Mass plastic cap molding after sample approved

FAQ

Q1: How many molding shots can the S136 injection mold achieve?
A: Well-maintained S136 HRC48-52 injection mold can reach more than 600,000 shots for LDPE cap continuous production.
Q2: Can you change cap dimension by modifying the existing injection mold?
A: Yes, our mold workshop offers mold revision service to adjust cap height, inner diameter and thread specification as your updated design.
Q3: Can we get pre-production samples before bulk molding?
A: Sure, we arrange trial samples after mold completion for your quality confirmation before mass LDPE cap production.
Q4: Is it possible to replace LDPE with HDPE/PP on this 1*8 injection mold?
A: After simple gate and injection parameter optimization, the same injection mold can adapt HDPE or PP material molding upon technical assessment.
