Open-die forging · Dingxiang County, Shanxi Province, China
Gear blanks, shafts, tyres, wheels, rings and flanges to your drawings. Forging, ring rolling, heat treatment and preliminary machining — in one shop, under one control.
We accept drawings in PDF, DWG, STEP · Response to your request within 24 hours
Every item is made to a specific drawing. We do not sell "stock metal from the warehouse": we determine the forging schedule, upset ratio and machining allowance for your next processing step. Below are the six groups we handle most often.
Forgings for gear cutting and finished gear shafts after preliminary machining: allowance on the pitch circle, machined locating journals and faces for fixturing on the gear hobbing machine.
Stepped shafts, spindles, axles with collars and keyways. Preliminary turning with allowance for finish machining.
Large-size ring forgings and tyres for mills, rotary kilns and support assemblies. Ring rolling on D53 mills up to Ø 8 m.
Series batches of ring and disc blanks — including for travel and crane wheels, rollers and blocks. Size is stable from batch to batch, tooling is proven.
Flat, weld-neck and slip-on flanges from forged blanks — the metal grain runs along the contour, not across it. Plus rings, discs and weld-neck nozzles.
Thick-walled hydraulic cylinder sleeves, hollow shafts, rods and shells, including blanks for pressure vessels. Piercing and rolling — without a longitudinal weld seam.

We do not outsource ring rolling, heat treatment or machining. Everything that happens to the blank after forging stays under our control — that is exactly why dimensions and structure do not "drift" between processing stages.
Marking, cutting and heating to forging temperature under pyrometer control.
Open-die forging and stamping on hammers of 5–25 t and presses up to 8000 tf, with forging ratio control.
D53 ring-rolling mills for 2, 5 and 8 metres — to the finished profile without a weld seam.
Hardening, normalizing and tempering in 3 / 6 / 8 m furnaces according to the schedule set in the batch process.
Turning, boring, gear cutting. Chemical composition, mechanical properties, UT, dimensional report, packaging.

Equipment parameters are specified as-is — the customer has the right to request an inspection report before placing an order.
We supply blanks to those who finish the part themselves — machine-building and repair enterprises, not end consumers.
Gear rims and mill tyres, crusher housings, support rings, shafts and rollers for beneficiation equipment.
Forged blanks for gear cutting — with allowance on the pitch circle and machined bases for mounting on the machine.
Rolls, support rollers, tyres of rotary kilns and drying drums. Work with long service life and heat-resistant grades.
Flanges, shells and weld-neck forgings for pipeline valves, as well as ring blanks for power engineering.
Blanks for pressure vessels and apparatus: shells, heads, flange connections.
Travel and crane wheels, sheaves, rollers and support rollers for cranes, conveyors and material handling equipment.
Each batch ships with a set of documents. Below is what we issue as standard; the scope of inspection is agreed before production starts, not after.
Chemical composition, mechanical properties, heat treatment mode. Issued in a form similar to EN 10204 3.1.
Verification of metal soundness for the absence of internal defects per GOST R 55724 / EN 10228-3.
Dye penetrant or magnetic particle testing per GOST 21105 / EN 10228-1 — as required by the drawing.
Report on actual dimensions with deviations within the drawing. If required — at the customer's inspection points.
Certificates and approvals
The enterprise is entered in the Unified State Register of the PRC, code 91140921MACL02Y69J, foreign trade is included in the scope of activity. Valid certificates and their scope: list of certificates
Dingxiang is the "Home of Chinese forging". The tradition of ironworking here goes back more than two thousand years: metal was forged in these places as early as the Han dynasty, and in the Ming era local craftsmen were called "iron men". In 1999 the county was officially awarded the title of home of Chinese forging.
Today Dingxiang accounts for over 30 % of the Chinese market for forged flanges and about 70 % of their exports, and its share in the production of flanges for wind power exceeds 60 %. This is Asia's largest base for flange production. Our plant operates right here — at a site in Dingxiang County, with its own equipment fleet and five workshops: cutting, heating, forging, ring rolling, heat treatment.
