Donsen idakhazikitsidwa mu 1996, yomwe ili ku NINGBO komwe kuli mzinda wotukuka komanso wokongola padziko lonse lapansi.Kukhala ndi zaka zoposa 10 zinachitikira m'munda uno, ndife mmodzi wa opanga akatswiri okhazikika kupanga mapaipi pulasitiki kwa madzi ndi ulimi wothirira.
Zogulitsa zathu zazikulu ndi mapaipi a PP-R ndi zovekera, zovekera za PP, mapaipi a C-PVC ndi zolumikizira, mapaipi a U-PVC ndi zozolowera, mipope yotentha ya PE-RT pansi, nkhungu zapulasitiki ndi mitundu yonse ya mavavu apulasitiki.Mwachitsanzo: PVC valve, PPR valve, C-PVC valve, valavu ya BRASS.
Tsopano mankhwala athu chimagwiritsidwa ntchito m'madera monga ngalande tauni, kotunga madzi boma, kukongoletsa kunyumba, ulimi wothirira munda ndi ulimi ulimi wothirira etc.
Pofuna kuti mabanja masauzande ambiri agwiritse ntchito chitoliro cha chilengedwe komanso chapamwamba, Donsen amagwiritsa ntchito zipangizo zamakono komanso zapamwamba kwambiri, pofuna kuonetsetsa kuti zinthu zili bwino, Donsen amatumiza kunja kwa PPR-AL-PPR yofanana ndi makulidwe a khoma lopangidwa ndi chitoliro. mzere, FR-PPR Fiberglass yopangidwa ndi makina opangidwa ndi makina apamwamba kwambiri, okwana 8 PPR mizere yopanga mapaipi, njira yophatikizira yodyera, makina opitilira 70 a jakisoni ndi zida zowunikira.Nthawi yomweyo gwiritsani ntchito makina m'malo mwa ntchito yamanja kuti mukhale otetezeka, olondola komanso odziwa zambiri.Pofuna kutsimikizira 100% khalidwe labwino kwambiri, Donsen amaika mosamalitsa cheke 3 poyang'anira ndi kuyang'anira qualiy, kuyang'anira zinthu zopangira, kuyang'anira ndondomeko, ndi kuyang'anira mankhwala kuzinthu zonse kuti atsimikizire ungwiro wa mankhwala.
kampani chimakwirira kudera la mamita lalikulu kuposa 40000, ali antchito oposa 400 ndi gulu la kasamalidwe luso msana ogwira ntchito.Likulu la kampani (A fakitale) makamaka kubala PPR chitoliro koyenera, B fakitale makamaka kubala C - mankhwala PVC ndi mitundu yonse ya mavavu.C fakitale makamaka kubala PP psinjika zovekera ndi zovekera zina mankhwala.Pali wapadera nkhungu fakitale ndi udindo kupanga mitundu yosiyanasiyana ya nkhungu zovekera pulasitiki.
Malinga ndi apamwamba ndi dzuwa mkulu, tili ndi satifiketi ISO9001:2000 ndi ISO14001, WRAS satifiketi ku England ndi GOST satifiketi ku Russia, NSF,UL, CE ndi zina zotero.Zogulitsa zathu zimatumizidwa kumayiko oposa 60, monga Venezuela, Russia, Ukraine, France, Italy, Middle East, etc. Donsen amalandira bwino mabwenzi padziko lonse lapansi, mfundo yathu ndi mgwirizano, kutenga nawo mbali ndi kukoka pamodzi!Mukuyang'ana wothandizira yekha padziko lonse lapansi!
