Second Round of Precision Fastening Reinforces Massage Pillow Core Stability

Following the initial automatic screw locking procedure on the assembly line, the workshop launches the second round of targeted screw tightening for the neck massage pillow’s core components, implementing dual inspection and reinforcement to eliminate hidden assembly defects and further elevate product durability and qualified rate.

This secondary fastening session targets key assembly positions including motor fixation, circuit board positioning and shell joint seams. Workers adopt handheld electric screwdrivers for point-by-point recheck and reinforcement. For parts finished by automated locking machines, staff verify screw torque and tightness one by one; for manually assembled structural positions, missing screws and loose connections are corrected on the spot. Compared with the first batch of mechanical locking, this procedure focuses on detail inspection, making up for individual deviation caused by equipment operation tolerance.

In the whole front-end manufacturing chain of the massage pillow, screw fastening serves as the foundational procedure to lock the gear transmission system, power motor and control circuit modules. Loose screws will directly lead to abnormal noise, gear deviation or circuit disconnection during long-term kneading operation. By setting two rounds of screw locking links, the factory builds a double quality barrier from standardized machine operation to manual re-inspection.

Supported by a complete set of pipelined production specifications, the brand strictly controls every small component assembly link. With 20 years of manufacturing experience and over 200 independent patents, the enterprise continues to optimize production details for OEM, ODM and bulk wholesale orders from global clients. The dual fastening process reduces post-sale failure rate effectively, helping the factory deliver more stable and reliable cervical massage health products to overseas markets.
