Bottle Cap Mould Parts

Bottle Cap Mould Parts are mold parts specially designed for the production of bottle caps, mainly including mold cavity, mold core, slider, ejector pin, cooling system, etc. They form a complete mold structure, and finally produce various types of bottle caps by heating, injecting, cooling and molding plastic or other materials.

Production process of Bottle Cap Mould Parts

CNC Machining: CNC machine tools are used to process mold parts with high precision to ensure that the size of the mold is accurate and meets the design requirements.

Wire cutting: For some complex mold parts, EDM wire cutting is used to obtain fine edges and shapes.

Heat treatment: Heat treatment of mold parts to improve their hardness and wear resistance, thereby extending the service life of the mold.

Grinding and polishing: The mold surface usually needs to be precisely ground and polished to ensure that the surface of the bottle cap is smooth and flawless.

Surface treatment: Nitriding, chrome plating or PVD coating can be performed to enhance the hardness, corrosion resistance and wear resistance of the mold surface.

Material selection

P20 steel: It is a commonly used plastic mold steel with good processing performance and hardness, suitable for manufacturing general-purpose bottle cap molds.

H13 steel: high temperature resistant, suitable for the molding of thermoplastic materials, often used to produce bottle cap molds with high requirements for high temperature resistance and wear resistance.

S136 stainless steel: strong corrosion resistance, suitable for bottle cap molds with high requirements for mold surface finish, such as transparent or colorful bottle caps.

718H steel: has good toughness and machinability, suitable for mass production.

Features

High precision: Bottle cap molds usually require extremely high precision to ensure that the size and shape of each bottle cap are consistent and avoid defects.

Strong wear resistance: Since bottle cap molds need to be used frequently, the part materials usually have strong wear resistance to extend the life of the mold.

Easy maintenance: The design and material selection of mold parts take into account easy maintenance and replacement to reduce downtime and maintenance costs.

Efficient cooling system: The mold is usually equipped with an efficient cooling system inside to speed up molding and improve production efficiency.

Application field

Beverage industry: used to produce mineral water bottle caps, carbonated beverage bottle caps, juice bottle caps, etc. Bottle caps for different beverages have different requirements, such as leakproof, anti-theft, sealing, etc.

Pharmaceutical industry: manufacturing pharmaceutical bottle caps, such as medical bottle caps with extremely high sealing requirements, to ensure the safety and effectiveness of drugs.

Cosmetic industry: producing cosmetic bottle caps, such as lotion bottle caps, perfume bottle caps, etc., which usually have high requirements for appearance.

Daily necessities industry: bottle caps used to produce products such as detergents and disinfectants usually require leakproof designs.

The design and manufacture of Bottle Cap Mould Parts have a direct impact on the quality, efficiency and appearance of bottle caps. By selecting the right materials and processes, the accuracy and consistency of the bottle caps can be ensured to meet the diverse needs of various industries for bottle caps.
