Quality is ourmain forte and we follow varied industry policies for achieving it. Furthermore,our quality consciousness has ensured that we manufacture premiumquality Screw & Barrel andmachines for the clients. We conduct various quality testson our range that start from the time of procuring raw material till the finalsupply of products. Apart from this, our quality controllers continuously checkthe entire range on different parameters so as to ensure its defect-free nature.Our quality testing laboratory is well-equipped with modern machines andtechnology that are necessary for bulk production.
Our factory islocatedat Zhoushan, Zhejiang thatis one of the prime industrial locations in the country. This factory isdesigned in a sophisticated manner to facilitate large units such asmanufacturing unit, quality testing unit, R&D unit, warehousing &packaging unit, sales & marketing unit and administrative unit. All thesedepartments possess equal amount of facilities that include advanced machineryand tools. In addition to this, all these units work in synchronization witheach other to manufacture and supply an impressive rangeof Screw & Barrel
Research is anintegral part of our organization and, we have established a separate R&Dunit. This unit is installed with sophisticated machines and technology that areessential for managing the varied research processes. Furthermore, our researchscholars conduct various market surveys so as to continually improve the qualityof the range of
Screw & Barrel and Machines. This team also makes sure that this range isregularly updated according to the current market scenario. Moreover, ourresearch scholars work hard towards introducing new products in the existingrange.
