Shengrong gray cast iron parts features
Shengrong iron casting parts based on standard EN1561-2011,surface smooth, dimensions accurate, actual weight no more 3% difference of theoretical weight, chemical composition meets the standards, no pores, no slag inclusions, no shrinkage holes inside, casting parts more stranger and good wear resistance than other factory
Why choose shengrong gray cast iron parts?
1:Shengrong casting foundry production capacity can meet your different size, weight from 0.5-10000kgs,the surface smooth, dimension aacurate,exzactly weight, casting parts no pores and defects, more stronger and resistance
2.Shengrong no MOQ requirement. For small order or samples, we make casting parts with lost foam castings-it is economic way. For big order, we make aluminum mold, quality more better
3.Shengrong carefully inspection of casting parts, test as tension, yield, and elongation, Non-destructive testing, and other test requirement as customer need.
4.Shengrong iron casting parts delivery time more quickly. For samples, 15-20days. For bulk order no more than 35 days. Samples free, you just only pay mold cost and air express shipping price.
5.Shengrong foundry packing in woodbox packing with anti-rust oil,can keep the casting parts in good condition after long time shipping
6.Shengrong foundry promiss 95% pass rate of our products. If less than this rate, we will send you new casting parts to replace the defects products
