Frequently Asked Questions
What industries is your company's testing equipment mainly suitable for?
We specialize in non-standard testing equipment for gas appliances and household appliances, especially in the gas appliance industry, with nearly thirty years of technical accumulation in the gas appliance industry, including gas water heaters, wall-hung boilers, and gas stoves. At the same time, the equipment is widely used in kitchen appliances such as range hoods, electric ovens, and sterilizers, as well as in environmental reliability testing fields like salt spray tests and high and low temperature tests. In addition, industrial automation inspection solutions can be customized according to customer requirements.
Do you make standard equipment or non-standard customization?
Focusing mainly on non-standard customs. Each production line and every product category has unique testing requirements. We provide a full range of customized services from solution design, mechanical manufacturing, electrical control, to software integration based on your inspection targets (such as valve bodies, complete machines), inspection items (performance, aging, lifespan), production line cycles, and environmental conditions. There are already numerous successful non-standard cases in the gas appliance and home appliance industries for reference.
How is the precision and stability of the equipment? How to verify it?
Before leaving the factory, we conduct complete machine testing and precision calibration according to national or industry specifications, and can provide actual measurement data reports. Common verification methods include: repeated testing with standard samples, comparison with customers' existing qualified equipment, or testing by third-party metrology agencies. For key parameters such as gas flow, pressure, and temperature, we also provide calibration recommendations and cycle reminders. For projects requiring extremely high precision, free sample testing can be arranged.
How long does it take to customize a device? Will it affect my production?
The project duration depends on the complexity of the equipment, generally 4~8 weeks, and includes requirements confirmation, solution design, manufacturing, factory pre-commissioning, and on-site installation. We complete pre-assembly and functional testing of the entire machine in the factory, and only a short time of wiring and fine-tuning can be done on site for trial operation. We will communicate with you in advance about the production shutdown window and develop a detailed installation schedule to minimize the impact on production.
Is the equipment complex to operate? What training do you offer?
The equipment uses a touchscreen human-machine interface, with simple operation logic; ordinary workers can use it daily after half a day of training. We offer tiered training: operator training (power on/off, data retrieval, fixture change), technician training (parameter adjustment, simple fault handling), and engineer training (system configuration, deep maintenance). It also provides a library of operation videos and illustrated manuals for easy access at any time.
