Quality Assurance

Quality Control

Inspection, electrical testing and traceability checks keep surge protection quality consistent across every production batch.

From incoming materials to final shipment, documented controls and test records provide clear batch traceability.

Control Process

Three Gates One Consistent Standard

Quality is built into each production stage rather than inspected only at the end. The same checklist follows every order, whether it is a sample run or a container shipment.

Single-pole surge protective device module inspected at incoming material stage

Raw Material Inspection

MOV chips, housings and terminals are verified against approved drawings and sample references before line release.

Three-pole surge protective device assembled for in-line process control

Production Process Control

Work instructions, torque settings and polarity marks are checked at each station to keep assembly repeatable across shifts.

Completed surge protective device inspected before release

Finished Product Inspection

Appearance, marking and final electrical re-check are completed and recorded before any unit is released.

Testing Facility

Inside the Test Laboratory

In-house test benches support routine verification and type-test preparation, with records retained for each production batch.

Traceability

Every Batch Leaves a Clear Record

From incoming lot to shipment, each order carries a documented control plan and a matched set of test records.
