   Finecaster Casting (Zhenjiang) Co., Ltd is a new enterprise reformed from state-owned Zhenjiang Automotive Casting Factory, which founded in 1966,belonged to the Southern Group(now the SAIC) to supply the professional cast iron auto parts. Stuff of 500 people, annual production more than 15 thousand tons, with ISO90000:20000 certification,, products exported to France ,Germany, Italy, USA and other countries, won national award of quality controlling from the government every year.

   Our company has experience of 40 years and advanced technology. We built a horizontal continuous casting production line on 2009 and officially operated in the end of 2010. Now we have production capability of continuous cast iron round bars & billets up to 10000 tons and mechanical processing capability of 7000 tons annual.

   We have 8 R&D stuffs working on development of products and QC research. Manage all departments by running ERP system. More than 40 machining equipments, more than 10 type of testing equipments (include SPECTROMAXX). The area of factory is up to 10000 square meters. Two more plants are building up.

    Now our products are used widespread in below area:

1. Hydraulic pressure and pneumatic parts field: valve, fairlead, gear wheel and piston;

2. Machine tool parts:  sea saw, guiding rail, worktable and transmission gear;

3. Metallurgy machine parts: the transporting roller for the high-speed wire rolling mill;

4. Refrigerator compressor parts: piston ring and sliding blade:

5. Mould fields: glass mould, plastic mould, grinding wheel mould and die-casting mould etc.

6. Car components: gear, gear box etc.

7. Weave and printing machine parts: roller, axis, gear and flange;

8. Train making fields: dowel ringer of veering framework for express train.
