A: Our factory strictly controls each process according to the following management steps.

1. Source control: Research and development and supplier access management
● The strict selection and control of the core raw materials (such as copper parts, silver contacts, plastic casings, electromagnetic coils, and trip devices) for circuit breakers directly determine the product quality. Therefore, a supplier classification system needs to be established:
◇ Pre-admission review of qualifications (production license, quality system certification), sample testing, on-site factory inspection;
◇ Regular incoming material inspection during cooperation (such as the conductivity of copper parts, the flame retardant grade of plastic, the purity of silver contacts), non-compliant materials are directly returned;
◇ Establish a list of qualified suppliers, and eliminate unstable suppliers.
2. Process Control: Standardized Operations in the Production Phase
● Standardization of production lines and error-proof design formulate standardized operation procedures (SOP), clearly defining the operation specifications for each process, such as:
◇ The sequence of component assembly, torque requirements (such as the tightening force of screws to avoid loose or tight situations that cause poor contact);
◇ Parameters for processes such as welding and injection molding (temperature, time), to prevent short circuits and shell deformation; at the same time, introduce error-proof devices, such as sensors in the automated assembly line to avoid missing parts or incorrect model installation.
● Process inspection and first-piece inspection
◇ Conduct first-piece inspection before each batch of production, confirmed by the quality inspector that the size, assembly, and performance of the first-piece product meet the requirements, and only after passing can mass production be carried out;
◇ During production, the quality inspector conducts regular inspections of each process, such as checking the assembly gap and the clarity of marking printing, promptly identifying deviations and making adjustments.
3. Core Assurance: Comprehensive Testing and Trials
Testing is the key to controlling the quality of circuit breakers, covering the entire stages of incoming materials, semi-finished products, and finished products, divided into regular testing and type tests:
● Regular Testing (mandatory for each batch)
◇ Appearance and size inspection: Check if the casing has scratches or deformation, whether the dimensions of components are in accordance with the drawings, and if the markings are clear and complete;
◇ Electrical performance testing: Test the temperature rise, contact resistance, insulation resistance (to prevent leakage), dielectric strength (resistance to high-voltage breakdown) under the rated current;
◇ Trip characteristic testing: Verify the accuracy of overload trip and short-circuit trip, such as when the overload is 1.3 times the rated current, it should trip within the specified time; during a short circuit, it should trip instantly to avoid line damage;
◇ Mechanical life test: Simulate closing and opening operations (usually requiring thousands to tens of thousands of times), to ensure the stability of the mechanical structure.
● Type Test (mandatory for new products or design changes) Entrust a third-party laboratory or own testing laboratory to conduct extreme breaking capacity tests, heat resistance tests, corrosion resistance tests, electromagnetic compatibility tests, etc., to verify the performance of the product under extreme conditions, ensuring compliance with certification requirements (such as CE, CCC, UL).
