Machine Introduction
Automatic Linear Screw Capping Machine is suitable for plastic and metal screw cap, which can handle a wide range of bottles without any change-parts for different bottle sizes. Our capping machine consists of two main components: the cap screwing unit and the cap feeding system with hopper. This capping machine is very ideal for application in Pharmaceutical, Food, Beverage, Cosmetic and other industries.

Machine Layout
The Ry-CM-3 automatic linear screw capping machine applies plastic and metal screw caps to bottles at speeds ranging from 10 to 100 bottles per minute. Designed for pharmaceutical, food, beverage, and cosmetic production lines, this capper handles bottle diameters up to 120mm and cap diameters up to 90mm without requiring change parts when switching between different bottle sizes. That capability alone saves production teams hours of downtime typically lost to mechanical reconfiguration during product changeovers.
The machine weighs 510 kg and occupies a footprint of 2,280 x 1,080 x 1,940 mm, positioning it as a mid-range capping solution for facilities processing moderate to high bottle volumes. A 1.8 kW motor drives the conveyor, cap elevator, and three pairs of spinning screw wheels that tighten each cap to the correct torque. The system requires a compressed air supply at 0.6 MPa with a consumption rate of 3 liters per minute for the pneumatic cap feeding and bottle separation mechanisms.
The capping cycle begins when an operator pours caps into the hopper. A cap elevator automatically sorts and lifts the caps, conveying them through a feeding chute to the cap loading position. Meanwhile, the conveyor belt brings bottles forward continuously, and a bottle separation mechanism maintains precise spacing between consecutive bottles to ensure each one receives exactly one cap.
As each bottle passes the end of the cap feeding chute, a cap is automatically applied onto the bottle mouth. A cap pressing head then presses the cap to a horizontal angle, preparing it for the screwing stage. Three pairs of constantly spinning wheels rotate in sequence to tighten the cap, with each pair applying progressive torque until the cap reaches the correct tightness. After capping, an aluminum foil detection device checks each bottle for the presence of a foil liner inside the cap. Bottles missing the foil liner are automatically rejected from the line, preventing incomplete packages from reaching downstream labeling and cartoning stations.
Pharmaceutical manufacturers deploy the Ry-CM-3 for capping medicine bottles, syrup containers, and supplement jars with plastic screw caps or metal caps. Food and beverage producers use it for sauce bottles, juice containers, cooking oil bottles, and condiment packaging. Cosmetic companies rely on it for skincare cream jars, lotion bottles, and serum containers. The machine handles round, square, PET, and HDPE bottles within its specified size range, covering the majority of standard container formats used in these industries.
The Ry-CM-3 is built with a SUS304 stainless steel frame and meets GMP-oriented pharmaceutical production requirements. Optional SUS316 stainless steel contact parts are available for applications requiring enhanced chemical resistance. CE certification is supported, and the machine complies with international export standards for packaging equipment shipped to North America, Europe, the Middle East, and Southeast Asia.
Hangzhou Ruiyi Machinery Technology Co., Ltd. has manufactured packaging machinery for over 20 years. The company operates a 70-person facility with a dedicated 10-engineer R&D division, exporting equipment to 50 countries worldwide including the United States, Canada, Germany, Spain, Mexico, Thailand, and Indonesia.
The capping machine serves as a critical component within an automated bottling line, positioned after the counting or filling station and before the induction sealing and labeling stations. It integrates with:
Conveyor height, signal interface protocols, and feeding direction are customizable to match your existing line layout.
Every machine includes operation manuals and installation videos. Remote technical support and troubleshooting services are provided for the lifetime of the equipment. Overseas engineer visits for installation and training can be arranged based on project requirements. Single machine delivery typically takes 7 to 15 working days, with complete integrated production lines requiring 20 to 30 working days depending on configuration complexity.
To request a quotation, please provide your bottle specifications including diameter and height, cap type and dimensions, required capping speed, and local voltage. Our engineering team will recommend the appropriate configuration and provide a detailed proposal.
