Product Design and casting simulation

Successful parts are original from successful design. We own high level engineers on the product design. They are good at make drawing using the software of CAD. PROE, SOLIDWORKS for assuring production process well.

Our technical group have rich experience in casting process, so we can put forward reasonable suggestions to the product structure design on various performance, process parameters to solve the customer's requirement, set up the 3D model, get the results from pouring simulation analysis. Then modify and optimize the scheme to determine the correct casting
