A jar preform mold is a tool used to create plastic preforms—small, tube-like shapes with threaded necks—for jars, typically made of PET. It forms the preform through injection molding, which is later blown into the final jar shape via blow molding, used for packaging food, cosmetics, and more. They are also used in packaging applications such as aseptic jars, dry food containers, snack jars, and more.

Key Features:

• Interchangeable Component Design: 80% of components can be replaced directly on the injection molding machine, ensuring minimal downtime and cost-efficiency.
• Valve Gate Hot Runner System: Pass Card's advanced design enhances flow control and minimizes waste.
• High-Quality Materials:

• Mold Base: PDS-5 (P-20) high-grade tooling steel, heat-treated to HRC 27~35 for durability.
• Core & Cavity: Swedish ASSAB STAVAX-420 hardened stainless steel, heat-treated to HRC 50~52 for superior strength and corrosion resistance.

With a focus on efficiency and flexibility, the jar preform mold is great for high-volume production in industries requiring packaging solutions. Pass Card is one of the leading mold manufacturers in Taiwan. Please do not hesitate to contact us for further details about the product.
