Its main activity areas can be grouped as follows:
- PET packaging moulds for preforms and bottles.
- Closure and accessory moulds, including bottle-cap and hand-held ring moulds.
- Medical moulds for healthcare-related plastic products.
- Associated equipment and technical services linked to mould and machinery development.
The company’s location in Fogang County, Qingyuan places it in a manufacturing region of Guangdong with access to the province’s dense plastics, machinery, and export-oriented supply chains.
Products and Technologies
The company’s product portfolio is centered on precision injection and blow mould tooling for PET packaging and selected medical applications. Public listings and group materials identify the following product classes:
- Preform moulds for PET bottle blanks.
- Bottle-blowing moulds for finished PET containers.
- Bottle-cap moulds for closures.
- Hand-held ring moulds for packaging and container accessories.
- Medical moulds for healthcare-related plastic parts and products.
Technical descriptions associated with Guozhu’s mould offerings mention conformal cooling, special surface treatment, advanced hot-runner technology, and interchangeability in PET sampling and blood-tube mould systems. These features are consistent with mould engineering priorities in high-volume plastics production, where cycle time, thermal balance, part consistency, and maintenance efficiency are central performance metrics.
Industry and company materials also connect the group to PET injection and blow-moulding equipment, including:
