Coolmay Opens Its 10 Quality Gates: 5 Testing Labs and 70+ Precision Devices Behind Every Controller
In industrial automation, the gap between a design drawing and a mass-produced unit is crossed at an invisible checkpoint: quality inspection. Many manufacturers stay silent about it, because the strictness of their testing standards decides whether a controller merely works in a showroom - or survives years on a real factory floor. Coolmay has chosen to open that checkpoint wide. Behind every unit sit ten quality-inspection gates, five dedicated testing laboratories, more than 70 high-precision test instruments, and a testing center built on a 5 million RMB investment.
In this industry there is always someone ready to fight a price war, but the quality war can only be fought by those willing to spend real money. Coolmay chose the quality war. As the company's quality director explains, testing standards are what separate products that "hold up" from those that fail once they reach the workshop. That is why Coolmay lays its process out in the open instead of keeping it behind closed doors.
| Laboratory | What It Verifies |
|---|---|
| Electrical Lab | Overall electrical performance, extreme and abnormal-condition testing, temperature-rise testing, control and protection functions, plus hardware and software white-box testing. |
| EMC Lab | Electromagnetic interference (EMI) and immunity (EMS): harmonic current, flicker, conducted and radiated disturbance, ESD, electrical fast transients, surge, and voltage dips and short interruptions. |
| Safety Lab | Safety-compliant design that prevents electric shock, fire, and mechanical or thermal hazards during normal and abnormal use. |
| Environment & Reliability Lab | High- and low-temperature operation and storage, thermal shock, constant temperature and humidity, vibration, drop, and salt-spray testing. |
| Material Certification Lab | Complete validation of incoming materials - electronic components, plastics and hardware - including dedicated failure analysis. |
The ten gates are not a single inspection step but a chain that runs from design to delivery. They cover quality assurance during design and development, quality assurance during production, product reliability testing, EMC testing and safety testing. At every stage the goal is the same: not a single defect should reach the customer. "Ten quality gates are the rules; five test rooms are the confidence; five million of investment is the attitude," the company says.
To make those gates meaningful, Coolmay has equipped its facilities with more than 70 high-precision testing devices. These instruments verify electrical behavior, electromagnetic compatibility, safety and long-term reliability long before a product ships. For buyers of HMI PLC all-in-one controllers, PLCs, touchscreens, servo all-in-one drives and inverters, that translates into fewer field failures, less downtime and a lower total cost of ownership.
Founded in 2006, Coolmay designs and manufactures HMI, PLC and HMI/PLC all-in-one products, along with servo all-in-one drives and inverters, under the Coolmay brand. Its slogan, "Keep innovation. Move forward," is matched by a simple promise: reliable automation products customers can use with confidence. In a market full of shortcuts, Coolmay's ten quality gates and five testing labs are its answer.
