Our aim is to provide products with Zero defects.
In Huanhai Tongda, every staff emphasizes quality is first. Testing report and samples of all products will be kept by our quality control department.
>> Receiving inspection to raw material
All materials must be provided with suppliers’ certificates, and have to pass the receiving inspection before starting production. Occasionally, material samples will be sent to independent lab for specific test to meet customers’ demands. All materials have to be tagged and classified, so the original source could be traced at any time during production processes.
>> Producing inspection
Every phase of production processes will be monitored by producing inspection. The first product shall accept test in every phase of production process. Only it completes the test and confirmed by quality control manager, mass production could be operated. Every producing operator will implement constant tests during production processes, including size-measuring, observing the appearance.
Products of Huanhai Tongda only can get out of the warehouses after all files signed and sealed.
