SINO Technical Research Institution.
Cooperated with Germany, Japan, Taiwan technical research institution, Sino keeps enhancing the ability on professional customization, creative R&D, efficient delivery and 7*24 hours after-sale service to meet different customer needs all over the world.
Absorbing advanced design ideas from Japan and Taiwan, combining with our long years experience in metal working industry, we design our own machines. Structure of Machine body, saddle and column etc, all had been optimized by CAE system, and also analyzed by FEM.
Every mechanical or electrical engineer express their craftsmanship spirit on design to pattern assembly and electrical development. CAD and Solidwork tools assist our engineers to express their ideas of maximum accuracy and stability on products combined practical experience and knowledge.
Every year our engineers will go to Japan SKTD and PMC company to study advanced design technology and exchange ideas. It is important to stand together with front-runner. As SINO has already merged Taiwan Campro, Jiaxing branch, our manufacturing SOP and PLC ability will introduced from Taiwan Campro directly.
High reliability is prior to high function.
