PET Blowing Mold
500ml Blowing Mold
Product Features
Durable and Wear-Resistant Surface Treatment
The mold cavity surface undergoes a hardening process combined with polishing technology, significantly reducing the coefficient of friction and the risk of material adhesion. This minimizes the frequency of downtime for cleaning and supports long-term, stable production of high-gloss bottles.
It is compatible with complex filling environments such as carbonated beverages and acidic liquids, preventing seal failure at the bottle mouth caused by medium-induced corrosion.
Modular Quick-Change Compatibility Design
The mold cavity components feature standardized quick-release interfaces, supporting rapid format changes for mainstream blow molding equipment. Compared to traditional structures, mold changeover time is significantly reduced, making it suitable for multi-variety, small-batch flexible production scenarios.
The split-structure design allows partial component replacement, reducing maintenance costs and extending the overall service life of the mold.
Compatibility with Sustainability and Lightweighting
Compatible with recycled PET (rPET) and bio-based resin materials, minimizing color variation or strength loss caused by differences in material thermal history, and supporting customers in achieving low-carbon production goals.
Lightweight bottle structure design reduces raw material consumption while maintaining bottle compression resistance and stacking stability, aligning with global sustainable packaging trends.
Application Scenarios
Carbonated Beverages and Functional Drinks:
Designed to meet the high pressure resistance requirements of carbonated beverage bottles. By optimizing the sealing surface at the bottle mouth and the wall thickness distribution of the bottle body, sealing performance and deformation resistance under high-pressure conditions are ensured.
Daily Chemical and Pharmaceutical Packaging:
High-precision mold cavity control ensures the accuracy of bottle neck threads and sealing structures, meeting the stringent airtightness and hygiene standards required for cosmetic and pharmaceutical bottles. Supports tamper-evident cap designs.
Eco-Friendly Lightweight Packaging:
Compatible with the molding of biodegradable materials used in disposable water cups and food containers. Lightweight design reduces plastic usage, aligning with global plastic reduction policies.
