MATERIAL ANALYSIS

In terms of product policy, TA TOONG WANG adopts ability oriented training and precise quality. The harness and flexibility of products must conform to the certain standards. In order to conform to the certain harness and flexibility standard, the product material, high-class casting iron, is refined with special methods.

Most of processing products must be gone through special nitrogen treatment, which will make the surface harness up to HV680 and then be examined by QC department. Only the passed products are packaged and shipped. The strict examination will bring the products to the standards of first-class world level.
