A car is an electromechanical hybrid system made up of thousands of parts. Automotive Gauge Accessories can help automakers and component manufacturers get detailed reports on component quality to improve component performance. Covering the environmental reliability test of auto parts, electrical performance test, functional test, electromagnetic compatibility test, material test, environmental protection test, chemical regulations, etc., then what are the classification and inspection items of auto parts.

Auto parts are mainly composed of auto steering system parts, auto driving system parts, auto electrical and instrument system parts, auto lamps, auto modification parts, engine parts It is composed of eight parts, transmission system parts and brake system parts.

1. Automobile steering system parts: king pin, steering gear, steering knuckle, ball pin, etc.

2. Automobile driving system parts: rear axle, air suspension system, balance weight, steel plate, etc.

3. Automotive electrical parts: sensors, lights, spark plugs, batteries, etc.

4. Auto lamps: decorative lamps, anti-fog lamps, ceiling lamps, headlights, searchlights, etc.

5. Car modification accessories: air pump, roof box, roof rack, electric winch, etc.

6. Engine parts: engine, engine assembly, throttle body, cylinder block, tensioner, etc.

7. Powertrain components: clutches, transmissions, gear lever assemblies, reducers, magnetic materials, etc.

8. Brake system components: brake master cylinder, brake cylinder, brake assembly, brake pedal assembly, compressor, brake disc, brake Drums etc.

The inspection items of auto gage accessories are mainly composed of two parts: metal parts inspection items and polymer parts inspection items.

The main inspection items of auto inspection fixture accessories are

1. Mechanical performance test: tensile test, bending test, hardness test, impact test, etc.

2. Component analysis: qualitative and quantitative analysis of components, trace element analysis, etc.

3. Structural analysis: metallographic analysis, non-destructive testing, coating analysis, etc.

4. Size measurement: three-coordinate measurement, projector measurement, precision caliper measurement, etc.

What are the main inspection items for auto inspection tools?

1. Physical performance test: tensile test (including room temperature and high and low temperature), bending test (including room temperature and high and low temperature), impact test (including room temperature and high and low temperature ), hardness, haze, tear strength, etc.

2. Thermal performance test: glass transition temperature, melting index, Vicat temperature softening point, low temperature brittleness temperature, melting point, thermal expansion coefficient, thermal conductivity, etc.

3. Electrical property testing of rubber and plastic: surface resistance, dielectric constant, dielectric loss, dielectric strength, volume resistivity, withstand voltage, breakdown voltage, etc. .

4. Combustion performance test: vertical combustion test, horizontal combustion test, 45-angle combustion test, FFVSS 302, ISO 3975 and other standards.
