38MM cap plastic injection mould in Shuanghao

Mould Feature

1. Full automatic, high efficiency and less maintenance cost.

2. Cap weight is light, which saves plastic material cost.

3. Each cavity and core have independent cooling system, shortening production cycle time.

4. We do leakage test carefully to ensure the cap is suitable for bottle.

5. Rational mould design to extend mould life and get high production efficiency.

Leak-proof design of bottle cap mould
Beverage bottle cap mold is made of PE (polyethylene) and weighs 2.9g. The outer side of the bottle cap body is evenly distributed with 120 anti-skid ribs to increase friction, and the top of the bottle cap has the brand name ZSM. An anti-counterfeit ring on the bottom of the bottle cap is connected to the main body of the bottle cap through eight small cylinders with a diameter of φ1mm and a height of 1mm. Inside the security ring, there are eight semicircular bosses with a uniform length of 3mm and a diameter of φ1.5mm. The inside of the bottle cap has a semi-circular thread and a security ring with a height of 4mm and a cross section diameter of φ1mm that closely matches the inner diameter of the bottle, while a security ring with a height of 1mm and a cross section diameter of φ1mm closely cooperates with the outer diameter of the bottle to prevent leakage.
    As plastic bottle caps have the characteristics of strong plasticity, low density, high specific strength, bonding, high chemical stability, and various appearances, they are loved by more and more manufacturers and people. The demand for plastic bottle cap moldings is increasing, and the quality requirements are becoming higher and higher. This requires the development of molds for molding plastic parts, and the level of design and manufacturing must also be higher and higher.
