Our company included 2 branch factories with related machining
capability. One is silica sol (lost wax) precision casting factory and
the other is resin sand casting factory. Our business range from
stainless steel casting, heat-resistant steel casting, carbon steel
casting, alloy steel casting, abrasion-resistant casting to iron casting

利用水溶芯和陶瓷芯，我们可以铸出更深的孔。
Deeper holes can be casted by using soluble cores and
ceramic cores.

我公司有能力对铸件表面作如下精整处理：对于碳钢和低合金钢可作发黑、镀锌、镀铬、镀镍处理；对于不锈钢铸件，可作研磨、拉丝抛光、镜面抛光、电解抛光、钝化处理。
The surface finish for the casting we can provide with
is as the following:Blacking、Zinc plating、chrome plating
and nickel plating for the carbon steel and the low
alloy steel castings;Tumbling、 dull polishing、 mirror
polishing、electrolytic polishing、and passivation
treatment for the stainless steel castings.
