Testing of household appliance components: Professional equipment ensures quality, and we offer complete solutions for your needs.

For a high-quality home appliance, the quality of every single component, from the core parts to the smallest details, is crucial to overall performance and safety. As a professional manufacturer of home appliance testing equipment, we understand that component testing is the "first line of defense" in ensuring product quality. From compressors and heating elements to thermostats and connectors, we offer comprehensive testing equipment for all types of components, providing accurate test data to support the entire process of R&D, production, and quality control for our clients.

1. Testing of Core Power Components: A "Performance Checkup" for Compressors and Motors

Compressors and motors are the "heart" of home appliances; their efficiency and durability directly determine the product's lifespan. For air conditioner and refrigerator compressors, our comprehensive compressor performance test system can simulate ambient temperatures ranging from -30°C to 60°C, accurately measuring cooling capacity, input power, and energy efficiency ratio (COP) under various operating conditions.  A 5000-hour continuous operation test verifies its durability, and real-time vibration monitoring ensures that the compressor's performance degradation remains within 15% over a 10-year lifespan.

For motor-driven components such as washing machine motors and fan motors, the motor life testing system can perform 100,000 start-stop cycles and 2000 hours of full-load operation tests. Equipped with a torque sensor and temperature recorder, it strictly controls the motor operating temperature (no more than 120°C) and torque fluctuation (deviation ≤ 5%). For frequency-inverter motors, the equipment can also simulate voltage fluctuations (180V-240V) and frequency variations (50Hz±2Hz), comprehensively verifying its adaptability under complex power grid conditions.

2. Testing of Heating Elements: Ensuring the Safety of Heating Tubes and Heaters

Heating tubes for electric water heaters, heating elements for electric ovens, and other heating components must meet both high efficiency and safety standards. Our immersion heating tube testing system is specifically designed for water heating components: it performs 10,000 cycles of "95°C heating - 20°C cooling" tests, along with a water corrosion simulation chamber (supporting various water types such as hard water and high-chlorine water), to test the corrosion rate of the tube wall (annual corrosion ≤ 0.1 mm) and insulation performance (hot resistance ≥ 50 MΩ).  A built-in pressure burst device applies 1.5 times the rated pressure for 1 hour to ensure no leakage risk. For air heating components (such as PTC heaters for air conditioners and heating modules for bathroom heaters), our dry-burn safety test rig simulates different airflow speeds and ambient temperatures, monitoring surface temperature uniformity (temperature difference ≤ 10°C) and flame retardancy during 8000 hours of continuous operation.  When the temperature exceeds a safety threshold (e.g., 180°C), it automatically records the response time of the protection device (≤ 3 seconds), preventing fire hazards due to dry burning.

3. Control and Connector Component Testing: "Precise Verification" of Thermostats and Connectors

The accuracy of thermostats and the reliability of connectors are crucial for the safe operation of home appliances. Our comprehensive life-cycle testing equipment for thermostats performs all-dimensional tests, including mechanical operation (50,000 on/off cycles), environmental stress (humidity, vibration, corrosion), and electrical load (1.25 times rated current).  Using high-precision temperature sensors (±0.1°C accuracy) and contact resistance testers, we ensure that the temperature control deviation remains ≤±2°C and the contact resistance increase is no more than 50%. For power plugs, terminal blocks, and other connectors, our plug-in/out life test machine simulates 10,000 insertion/extraction cycles, recording the change in insertion force (within ±20% of the initial force).  Combined with a salt spray corrosion test chamber (500 hours of salt spray) and an insulation resistance tester, we verify the corrosion resistance level of metal parts (≤5) and insulation performance (≥100MΩ), eliminating overheating and short-circuit issues caused by poor connections.

As a professional manufacturer of home appliance testing equipment, we not only provide standardized testing equipment (fully compliant with international and domestic standards such as IEC and GB), but also offer customized solutions to meet specific customer needs. From testing individual components to integrated system testing, and from precision laboratory instruments to online production line testing equipment, our solutions cover the entire process of home appliance component development and manufacturing. Each piece of equipment is equipped with a smart data management system that automatically generates test reports and life expectancy curves, helping companies quickly identify defects and optimize designs. Choosing our testing equipment means providing your home appliance components with "precision quality control." Ensuring that every resistor, every connection, and every function performs reliably and meets rigorous data standards, ultimately delivering safe, durable, and efficient home appliances to consumers – this is our responsibility as a testing equipment manufacturer, and the value we bring to the home appliance industry.
