The quality of a PET preform depends not only on the injection machine, but also on the precision, balance and durability of the mould behind every production cycle.
PET preform production is a high-speed manufacturing process used across bottled water, carbonated beverages, edible oil, food packaging, cosmetics and other consumer packaging applications. At the centre of this process is PET injection tooling. A well-designed PET preform mould influences cavity consistency, preform weight, cooling efficiency, cycle time, neck finish accuracy and long-term production stability.
As packaging manufacturers increasingly focus on lightweighting, recycled PET, higher production output and lower material consumption, demand for high-precision PET injection moulds and multi-cavity PET preform moulds continues to grow.
This article introduces 10 manufacturers and suppliers with established involvement in PET preform tooling. The list is an industry reference rather than a universal performance ranking. Buyers should evaluate each supplier according to cavity requirements, machine compatibility, preform design, production capacity, technical support and total tooling cost.

A PET preform mould is not simply a standard plastic injection mould. The mould must match the injection machine's platen, injection unit, cavity pitch, hot runner arrangement and other mechanical requirements.
Always provide the manufacturer with the exact machine model before mould design begins.
The supplier should receive the preform drawing, neck finish, preform weight, length, body diameter and bottle application.
For example, SZ-MOLDTECH publishes different cavity layouts and pitch configurations according to neck and preform dimensions.
The hot runner affects PET melt distribution, gate quality and material stability. Cooling affects cycle time, dimensional consistency and preform quality.
For high-cavity PET preform moulds, these systems must be balanced across all cavities rather than optimised for only one section of the mould.
A professional supplier should be able to explain its inspection and trial-production process.
Important checks include:
Cavity dimensions
Preform weight
Neck finish accuracy
Gate quality
Cooling performance
Mould opening and closing
Hot runner operation
Overall production stability
6 Frequently Asked Questions About PET Injection Moulds
A PET injection mould is used to manufacture PET preforms, which are subsequently reheated and stretch-blown into PET bottles or containers. The mould determines the basic dimensions and consistency of the preform.
The appropriate cavity count depends on required output, preform weight, cycle time, injection machine capacity, cooling capability and investment budget. Common configurations include 48, 72, 96, 128 and 144 cavities.
Yes. PET preform moulds can be customised according to preform drawings, neck finish, preform weight, cavity count, bottle application and injection machine specifications.
Yes, compatible tooling can be designed for major PET injection platforms. However, compatibility must be confirmed using the exact machine model and technical specifications before manufacturing.
Mould life depends on steel, machining accuracy, operating conditions, maintenance and production parameters. Different manufacturers provide different life-cycle specifications, so buyers should request a documented service-life target for the proposed mould.
A complete RFQ should include the preform drawing, neck finish, preform weight, dimensions, required cavity number, injection machine model, PET material, target output and any existing mould information. Providing these details allows the supplier to evaluate the mould structure and provide a more accurate quotation.
