Product Introduction
>Product Introduction
The case of Large Water Pump & Heavy Industral Pump & Electric Motor most are make by casting only, raw material are used Ductile Iron / Stainless steel or other alloy steel.
Large size cast case should have accurate dimensions , tensile strength, impact toughness, Machinability and other quality and technical requirements.
>Product Advantage
Relatively stable quality
NGZR have more than 10 years experience of R&D / Manufacutring / After-sales srevice for High Mn & High Cr alloy casting wear parts for Mining and Ductile iron castings for Electric motor shell and Water Pump sheel.
Lower price
NGZR have large production capacity with Advanced Lost foam process full Automatic precision casting line and Resin-sand Wooden mould manual casting production line, we can provide more competive price products to all customers.
Customized alloy Steel composition
NGZR foundry was able to match customer needs to readjust the Chemical Composition of alloy steel content (Mn /Cr) , or increased other special metallic element (Si /Mo /Cu /Ni etc), through special heat-treatment processing, can help this casting Excavator bucket wear-parts have special Mechanical performance, to follow different customer’s different working conditions.
Customized drawing size and shape
NGZR foundry can follow customer’s drawing of exist product to customized . Also we can revised the exist product shape / thickness to help customer get lower purchase cost.
