20-90mm Auto Screw Capping Machine for Cosmetics

Product Overview As a CE/FDA/GMP-compliant solution, it integrates advanced automation with hygienic design to deliver consistent capping performance across diverse container types. At its core is a servo-driven torque control system with an adjustable range of 0.1–5 N·m, ensuring ±0.1 N·m torque accuracy—a critical feature for preserving product integrity in sensitive formulations like serums and medicated creams. The machine’s robust 304 stainless steel frame boasts IP54 protection, making it resistant to corrosion and moisture in high-humidity production environments such as cosmetic labs and cleanrooms. Its PLC-controlled human-machine interface (HMI) simplifies operation, allowing operators to execute multi-format changeovers in <10 minutes—a significant efficiency boost for facilities handling multiple product lines.

Product Specifications

Parameter Value Material 304 stainless steel (FDA-approved for direct product contact, 2B surface finish) Cap Size 20–90 mm cap diameter (adjustable via quick-change tooling with memory function) Production Speed 30–40 bottles per minute Bottle Compatibility Round, square, flat and oval containers etc (70-320 mm height, 30-140 mm diameter) Power Supply 220V/50Hz 1-phase(customizable) Features 1. Servo-Driven Torque Precision The machine’s closed-loop servo motor forms the backbone of its capping accuracy, delivering ±0.1 N·m torque repeatability across thousands of cycles. This precision is vital for preventing product leakage in moisture-sensitive items like sunscreen lotions and ensuring easy opening for consumer-friendly packaging such as lotion pumps. A built-in magnetic clutch system acts as a safety buffer, automatically reducing torque if resistance exceeds preset limits—this feature alone reduces cap damage rates to <0.5%, minimizing material waste. For added control, operators can store up to 50 torque profiles in the PLC memory, enabling one-touch recall for recurring products.

2. Multi-Format Flexibility Designed to adapt to dynamic production needs, the capping head accommodates 20–90 mm caps of diameter without requiring tool changes, supported by quick-change guide rails that adjust to bottle heights from 70-320 mm. This flexibility shines in scenarios like switching from 30 mm cream jars (common in skincare lines) to 80 mm shampoo bottles—a transition that takes <8 minutes compared to 30+ minutes with manual systems. The machine’s conveyor system features variable speed synchronization, ensuring seamless integration with upstream filling equipment and downstream labeling stations, regardless of production pace.

3. Hygienic Design Hygiene is embedded in every component, starting with the IP54-rated enclosure that shields internal electronics from dust and liquid ingress. The stainless steel conveyor belt features a smooth, crevice-free surface that resists bacterial growth, while tool-free disassembly of contact parts simplifies deep cleaning. Operators can complete full sanitization between batches in <15 minutes, a critical advantage for facilities producing both cosmetic and pharmaceutical products. Additionally, the machine’s lubrication points are externally accessible, eliminating the risk of contamination from internal oil leaks.
