Company Introduction

In order to adapt to the market development, the die-casting company built a resin sand production line and a slot mold sand production line, with an annual output of 4,000 tons iron castings, and plan to purchase an automatic production line which can realize the production capability of gray iron,vermicular iron,ductile cast iron in total 6,000 tons.The company has good inspection ability, possesses many advanced inspection instruments, such as chemistry analyzer, spectrograph, tension tester, online temperature testing system, sand analysis equipment and internal inspection equipment,etc. Therefore, it can undertake almost all kinds of casting productions, the products are supplied to the domestic well-known automobile manufacturers,such as SGMW, small diesel engine procurement group of SAIC, Chery, Ningbo Geely, and also supplied to the rail transit manufacturers for 4 years which named Chongqing CAERI Vehicle transmission manufacturing Co., Ltd.

The die-casting plant is focus on the aluminum alloy die-casting, possessing 7 middle level and high level die casting machines which are produced by L.K.Group and Yizumi.The annual output of aluminum die casting products is 1,000 tons , after building another gravity casting production line, the production capability of annual output of aluminum die castings can reach 3,000 tons in all. Equipments with the press range from 180 tons to 1250 tons can undertake all kinds of microdiecast of aluminum die castings.The company is particularly skilled in producing 2 to 4kg medium aluminum alloys (by our 1250 tons automatic die casting machine) , and processing incoming material.

Chongqing Yingzhou Die-casting Co., Ltd. holds the operation philosophy of persisting in high quality and customer first. Currently, the company is ready to apply for the International Railway Industry Standard, TS16949 Quality Management System Certification. We warmly welcome friends from all over the world to visit and negotiate, and we seek for mutual developments.
