In the gas appliance industry, quality is not just about customer satisfaction — it is a safety issue. A faulty stove can leak gas or cause a fire. That is why a serious factory invests heavily in quality control at every stage. Here is how THREEMI does it.
Incoming Material Inspection
Quality starts before production. We inspect incoming steel, glass, brass, and components against specification before they reach the line. Substandard material never enters production.
In-Line Inspection During Assembly
At every production stage — stamping, pressing, glass processing, burner assembly, and final assembly — inspectors check dimensions, alignment, and finish. Catching a defect early costs far less than finding it after the stove is built and boxed.
Gas Leak and Performance Testing
Every gas stove is tested for gas tightness and flame performance before it is packed. Leak testing is non-negotiable: a single leaking unit can damage a brand and create liability. We test each burner for stable, even combustion.
Pre-Shipment Inspection
Before export, a final inspection verifies the product against the approved sample — appearance, function, packaging, and documentation. On request, we support third-party inspection so you have independent verification.
Certification-Backed Quality
Our quality system is built on ISO9001 and compliance with CE, UL, GS, ETL, NF, SASO, and CCC standards. When you buy from THREEMI, you buy a factory that treats quality as a system, not an afterthought.
