As the demand for plastic packaging continues to grow globally, injection preform moulds play an essential role in the manufacturing of PET bottles used across beverages, personal care, food, and chemical industries. At Langko Mould, we specialize in producing high-precision, high-cavity, long-lasting preform moulds designed to meet the evolving needs of modern packaging manufacturers.

What Is a Preform Mould?

A preform is an intermediate product produced by injection moulding, which is later blown into a plastic bottle using stretch blow moulding technology. The preform mould determines the dimensional accuracy, weight consistency, thread finish, and overall quality of the final bottle. A well-designed mould ensures efficient production cycles, reduced material waste, and consistently high product quality.

Why Choose Langko Preform Moulds?

1. Precision Manufacturing for Dimensional Consistency

We utilize high-precision CNC machining centers and advanced heat treatment processes to achieve mould part tolerances of ±0.01mm. This ensures uniform wall thickness, neck finish, and weight for every preform cavity — a critical factor in high-volume production.

2. High-Cavity Design for Increased Productivity

Langko offers preform moulds from 2 to 96 cavities, custom-designed based on your injection machine and production goals. With optimized cooling channels and runner design, our moulds support cycle times as low as 12 to 18 seconds, significantly boosting your output capacity.

3. Durable Steel for Long Tool Life

We select premium-grade materials such as S136, 2316, and imported H13 steel for critical mould components. These materials, combined with advanced polishing and tempering processes, ensure corrosion resistance and mould life of over 3 million shots under regular maintenance.

4. Flexible Hot Runner Integration

Our moulds are compatible with leading hot runner systems including Yudo, Husky, and Chinese brands. This flexibility ensures smooth resin flow, reduced gate vestige, and consistent color performance — even in complex or multi-color preforms.

5. Technical Support & After-Sales Service

At Langko, we provide more than just tooling. Our engineers offer mould testing, preform design optimization, energy efficiency advice, and on-site support to help clients maximize machine utilization and minimize downtime.

Application Fields

Our preform moulds are widely used in the following sectors:

• Bottled water and carbonated beverage bottles

• Edible oil and condiment bottles

• Personal care bottles (shampoo, body wash, etc.)

• Pharmaceutical and chemical packaging

Conclusion

In a competitive market, the right injection preform mould can make all the difference. With Langko Mould as your partner, you gain access to reliable tooling that enhances production efficiency, ensures consistent quality, and strengthens your brand’s competitive edge.

We look forward to helping you bring your packaging vision to life with precision and performance — made in China, trusted worldwide.
