Multi Cavity Beverage Bottle Cap Injection Mould

High-Speed Hot Runner Cap Mold for Packaging Industry

Product Overview

Our multi cavity beverage bottle cap injection mould is designed for high-volume production in the packaging industry.

Bottle cap manufacturing requires:

• Short cycle times

• Stable cavity-to-cavity consistency

• Uniform cap weight

• Reliable long-term operation

This mold solution is engineered for beverage, food, and cosmetic packaging applications where continuous production and repeatable quality are critical.

Application Industries

This injection mould is widely used in:

• Beverage bottle caps (water, juice, carbonated drinks)

• Food packaging closures

• Cosmetic bottle caps

• Household chemical packaging

• Pharmaceutical packaging components

These industries require stable mass production and strict dimensional consistency.

Key Engineering Focus

Bottle cap injection moulds operate under high-speed and multi-cavity conditions.
The main engineering priorities are flow balance, durability, and dimensional stability.

1) Multi-Cavity Balance & Weight Consistency

Cap molds are typically designed from 1×1 up to 1×32 cavity configurations.

• Balanced hot runner layout

• Uniform melt distribution to each cavity

• Consistent cap weight across all cavities

• Reduced dimensional deviation

Uniform cavity performance ensures sealing reliability and reduces scrap rate.

2) Advanced Hot Runner System

The hot runner system is critical for:

• Even temperature control

• Stable melt flow

• Reduced material waste

• Shorter cycle times

Precise thermal control prevents material degradation and supports eco-friendly lightweight cap designs.

3) Mold Durability for Continuous Production

Bottle cap production often runs 24/7.

• Wear-resistant mold steels

• Hardened core and cavity inserts

• Optimized cooling system layout

• Stable ejection structure

Mold components are designed for long service life and easy maintenance.

4) Standardized & Interchangeable Components

• Interchangeable cavity inserts

• Standard mold bases (LKM, HASCO, DME)

• Simplified maintenance and replacement

• Reduced downtime during servicing

Standardization improves long-term operational efficiency.

Technical FAQ

Q1: Can you manufacture 16 or 32 cavity cap molds?
Yes. Multi-cavity configurations up to 32 cavities are supported depending on cap size and design.

Q2: How do you ensure uniform cap weight?
Through balanced hot runner layout and precise cavity machining control.

Q3: Are lightweight eco-friendly cap designs supported?
Yes. Mold structure can be optimized for reduced material thickness and recyclable plastics such as PP and PE.

Q4: What is the typical cycle time?
Cycle time depends on cap design and material, but molds are engineered for high-speed production.

Q5: How is maintenance handled?
Standardized and interchangeable components allow easier servicing and reduced downtime.
