Massage appliances (massage cushions, massage chairs, massage guns) have complex structures and many moving parts, making them a high-frequency non-conformity category. Ningbo Xuntong Standard has catalogued the high-frequency problems from many tests and gives practical structural corrective-action advice to help businesses minimise risk before mass production.

1. Electrical safety

Leakage current, electric strength and earthing are basic mandatory checks; massage appliances with heating functions must also meet temperature-rise requirements. Ningbo Xuntong Standard advises manufacturers to verify insulation class and earthing continuity at the first-article circuit review to avoid major late changes.

2. Mechanical hazards

Moving-part guarding, crush points, noise and vibration are the focus; massage-gun types also need attention to battery safety and structural strength. The gap and locking method of the guard directly determine whether the product passes the mechanical-hazard test.

3. Structure and materials

Enclosure strength, button life and flexible-cord sheath flexing frequently cause problems. Ningbo Xuntong Standard recommends putting the structural review up front, using pre-test data to drive tooling changes rather than judging by experience.

4. Corrective-action path

Corrections usually start from three aspects: optimise the moving-part guard, strengthen the enclosure, and add redundant thermostats for heated models. Ningbo Xuntong Standard provides pre-testing and corrective-action guidance for massage appliances, covering electrical, mechanical and structural items in full.

Putting testing up front can significantly reduce tooling-change costs.
