About DASHAN
We are a Chinese manufacturer of custom bronze wear components — cast and machined in one plant, shipped to machinery owners on every continent.
Henan Dashan Nonferrous Metals Co., Ltd. has exported custom bronze wear components under the DASHAN brand for 13+ years. Production is handled by our own factory, Xinxiang Haishan Machinery Co., Ltd. — centrifugal, metal-mold, sand and investment casting plus CNC machining at one plant. Castings range from Ø20 mm to Ø6,000 mm in diameter and 0.1 kg to 15,000 kg per piece.
What We Do
DASHAN (Henan Dashan Nonferrous Metals Co., Ltd.) supplies the bronze parts that keep heavy machinery moving: bushings, bearings, crusher wear components and custom copper-alloy castings — manufactured by our own factory, Xinxiang Haishan Machinery Co., Ltd. Our focus is the wear parts of mining and heavy equipment — the positions where dirt, shock and long shifts punish material the hardest.
One Plant, Whole Responsibility
Most bronze parts travel between a foundry and a machine shop, with tolerances, distortion and schedules negotiated across two companies. Our foundry — centrifugal, sand and metal-mold casting — sits beside our CNC machine shop. Casting and machining in one plant means one party owns the entire tolerance chain, one schedule, one responsible supplier for the finished part.
Engineered for Service, Not for the Catalog
Every inquiry is answered by engineers who recommend the alloy, confirm dimensions and flag design issues before you pay for anything. We regularly reverse-engineer worn or failed parts — a sample, a part number, or even a set of photos is enough to start. Our in-house material lab analyzes each melt, and material certificates are available where your operation requires them.
13+ Years of Export Experience
Since the beginning we have served export customers: mining operations and equipment owners in Australia, Southeast Asia, Europe, Africa and North America. We quote in clear Incoterms, pack for sea or air freight, and handle export documentation in-house. Urgent parts ship by air; planned spares travel by sea.

Our Promise
Dimensions confirmed before production — first fit, finish fit.
Alloy recommended for your actual service, not our stock.
Lead time and price confirmed in writing on every quotation.
Parts that don't conform don't ship.
