North Mould Company have very strong capability to do the high precision machining works, and their local sourcing capability makes them to be a good supplier for various iron and steel parts. In addition, they are also a company for stamping steel parts.
These pump bodies were made by alloy steel castings. Qualified material grades and high precision machining are the key requirements. North Mould company entrusted the local steel foundries to produce the rough castings, and they completed the following machining, painting and inspection works in-house.
This is an assembly iron casting parts exported to USA. This part is produced by resin sand casting process, and have very high requirements to machining precision, painting and defects
In China, there are also many companies manufacturing iron and steel casting parts, stamping parts and welding products. Each manufacturer has their own strong points and week points, so learning their production processes and main products will be a good beginning to consider if they are your suitable suppliers.
