R&D

Our engineers have rich design experience and comprehensive development concept. Engineers adhere to the principle of "design is the key to mold", attach great importance to mold production process. Elaborate design, trying to create a mold with the longest service life, less maintenance times.

The customer only needs to provide 2d or 3D effect drawings or samples in DXF, DWG, PRT, SAT, IGES, STEP and other formats. Yijin will scan the samples and make product blueprints. Once the customer confirms, it can carry out mold assembly and drawing design according to the customer's existing projects.
