Cap & Closure Injection Moulding Machine
Our cap and closure injection moulding machines are specialized equipment for producing plastic bottle caps, widely used in packaging for beverages, personal care, food, and pharmaceuticals. These machines mainly use polyethylene (PE) and polypropylene (PP) plastic as raw materials, manufacturing caps of various specifications and shapes through injection moulding.
Key Parameters
- Number of cavities: 22/36/38/48
- Clamping force: 1400-2700kN
- Ejector force: 39-42kN
Samples of PE Cap
Features
Our machines can precisely control injection volume and mould temperature, ensuring the accuracy and consistency of cap dimensions.
With a short injection cycle, our machines are suitable for mass production.
Equipped with automatic feeding, automatic demoulding, and automatic detection, our machines reduce manual operations and increase production efficiency.
Our newly designed machines use servo motors and intelligent control systems, effectively reducing energy consumption and defect rates.
