SHUANGHAO Machinery is a professional manufacturer of bottle cap molds, specializing in precision injection molds for tamper evident caps widely used across chemical, food, pharmaceutical, and industrial packaging applications. Our high-quality closure molds produce secure sealing caps commonly found on motor oil bottles, reagent containers, chemical drums, large-capacity beverage bottles, and various industrial packaging vessels where product integrity and safety are paramount.
Tamper evident caps play a critical role in protecting product quality and ensuring consumer safety. SHUANGHAO tamper evident cap molds are precision-engineered to produce closures that provide clear visual indication of first opening, offering both security and peace of mind for end users. Each cap features a breakable band or bridge structure that remains attached to the bottle neck until the cap is first opened, providing unmistakable evidence of tampering.
Our molds are designed to accommodate various closure types, including:
Standard Tamper Evident Caps: Featuring a breakable ring that separates upon first opening
Push-Pull Tamper Evident Caps: Combining dispensing functionality with security features
High-Torque Industrial Caps: Designed for heavy-duty applications requiring secure sealing under demanding conditions
SHUANGHAO cap molds are manufactured using advanced CNC machining technology and premium tool steel, ensuring exceptional dimensional accuracy and long service life. Our molds incorporate sophisticated hot runner systems and multi-cavity configurations to maximize production efficiency while maintaining consistent quality across all output.
Material Compatibility: Our molds are optimized for processing a wide range of thermoplastics, including:
PP: Preferred for food contact applications, offering excellent chemical resistance and flexibility
PE: Ideal for industrial and chemical packaging, providing durability and moisture barrier properties
HDPE: Suitable for heavy-duty applications requiring superior strength and chemical resistance
Chemical and Industrial Packaging
For motor oil bottles, lubricant containers, chemical drums, and industrial solvents, SHUANGHAO tamper evident caps provide reliable sealing against leakage and contamination. Our molds produce caps with enhanced thread designs and gasket compatibility to ensure secure closure even with aggressive chemical contents.
