Under the guidance of "win the opposition through perfect quality", our enterprise has employed some of the most leaded great technicians in our personal profession and has introduced the most superior manufacturing technics and equipment in view that the establishment. We have authorities specializing in exceptional management. We have established and applied a strictly controlled and appreciably sensible production best assurance system. Each production glide is continually below managed so as an ideal product.
1.Quality management system and certificate of products
2. Keys of quality assurance control
The manufacturer license of Special of Equipment PRC
Products of high quality are bestowed by using exceptionally qualified and expert staff. Our agency trains the new body of workers otherwise in allusion to exclusive requirements of positions earlier than getting down to working. They can solely begin work after having exceeded the assessment. Furthermore, we skilled the body of workers periodically so as to enhance their expert operation level.
Advanced tools are the foundation of pleasant the requirement of realizing tremendous craftwork design. HUASHANG brings in the most advanced and expert laboratories, with the well-equipped facilities: drawing machines, eddy current test machines, hydraulic test equipment, hardness tester, impact tester. We also have the most advanced handheld spectrometer, which can do the one hundred percent PMI chemical test. Therefore, our company enjoys a high reputation for the high precision of size, the uniformity of the wall thickness of the pipes
3. Quality control of the raw materials
Our out-sourcing uncooked materials come from the certified suppliers after being strictly audited. After arriving at our factory, besides for inspection on the size and Facing and chemical, all the uncooked material has to be qualitatively examined and has to be quantificational spectrum examined. It is still the examining effects meet the general of our fabric inspection and the inspection document provided by means of the supplier, that will we use the materials. After that, we will input all the inspection statistics into our pc for higher management.
4. Control of the producing process
first-rate control throughout the producing manner is one of the most necessary taches of guaranteeing the excellent of the products.
