Mold Structure & Design Description

The mould adopts a 16-cavity hot runner layout to ensure uniform melt distribution and stable cavity pressure. Threaded core structures are engineered for accurate thread formation and reliable demolding. Cooling channels are optimized around cavity and core inserts to control cycle time and dimensional repeatability across all cavities.

Manufacturing Capability & CNC Machining

Senlan Precision manufactures hot runner moulds and critical mould components using high-precision CNC and EDM processes to meet multi-cavity mould requirements.

Manufacturing capabilities include:

• CNC milling and turning for mould plates and inserts

• Precision machining of threaded cores and cavities

• EDM and wire-cut EDM for complex internal structures

• Tight tolerance control for multi-cavity alignment

• Surface finishing suitable for cap mould applications

High-accuracy machining is supported by equipment from MAKINO and HARDINGE, ensuring stable dimensional control and repeatability.

Custom Development / OEM Cooperation Process

1. Customer provides drawings, samples, or technical specifications

2. Engineering review of cavity layout and hot runner configuration

3. Mold design confirmation (or built-to-print manufacturing)

4. CNC machining and EDM processing

5. Assembly and internal inspection

6. Final quality verification and export packing

All projects follow a Built-to-Print / OEM cooperation model.

FAQ – Technical & Purchasing

Q1: Is this mould suitable only for water bottle caps?
It is primarily designed for water bottle screw caps but can be adapted for similar cap designs based on customer specifications.

Q2: Can you supply only mould components instead of a full mould?
Yes. We support both complete mould supply and built-to-print mould component manufacturing.

Q3: How is cavity balance ensured in a 16-cavity hot runner mould?
Through hot runner layout optimization, precise machining, and cavity consistency control.

Q4: What information is required for quotation?
Cap drawings, cavity number, material type, hot runner requirements, and production volume expectations.
