Handheld electric bottle cap machine designed for fast, consistent capping of plastic screw caps (10–50 mm). Built to reduce wrist strain, improve throughput, and deliver durable, repeatable results. Key benefits Speeds up capping tasks and ensures consistent torque to avoid loose or overtightened caps. Ergonomic handle with antislip points reduces wrist fatigue during long periods of use. Sturdy construction resists deformation, giving reliable performance in production or manual packing environments. Two tools in one: converts between a capping machine and a screwdriver for flexible use and easy maintenance. Main features Compatibility: Works with most plastic screw caps 10–50 mm in diameter. Not suitable for beer bottles, glass caps, spray bottles, or dropper bottles. Torque performance: Torque range 3.0–30 kgf·cm for controlled tightening across different cap sizes and materials. Ergonomic design: Comfortable handle and antislip surface for safer, less tiring operation. Durable materials: Constructed from quality plastic, stainless steel, and alloy steel for strength and longevity. 2in1 functionality: Use as a capping machine by attaching the capping head; remove the capping head and use as a screwdriver for disassembly or other tasks. Practical use scenarios Smallbatch food and beverage producers: Quickly cap jars and bottles with plastic screw tops while maintaining consistent torque to protect seals and prevent leaks. Laboratories and cosmetic production: Assemble vials and containers with repeatable torque to protect samples and finished products. Light assembly and packaging operations: Switch between capping and screwdriver modes to handle multiple assembly steps without extra tools. What problems it solves Eliminates inconsistent handtightening that causes leaks or damaged caps. Reduces operator fatigue through ergonomic design and torque control. Lowers the need for multiple tools by combining capping and screwdriver functions in one handheld unit. Specifications Cap diameter compatibility: 10–50 mm (plastic screw caps only) Torque range: 3.0–30 kgf·cm Materials: quality plastic, stainless steel, alloy steel Function: electric handheld capping machine and removable screwdriver head Reliable, easy to use, and built for repeated operation — ideal for small production lines, packing stations, and maintenance tasks where consistent plastic cap tightening is required.
