About Us
Longkou Dayuan Machinery Parts Co., Ltd. currently is the first domestic company that is a high and new technology enterprise (HNTE) with international advanced level on precision cold forging production process(Cold Extrusion) . It is professional on a large scale to produce cold forging claw pole and magnetic core for all kinds of automobile alternator, brake caliper piston, steering ball joint, steering-gear spherical housing, flange, coupling shaft, and petroleum perforating housing etc. We can manufacture almost all kinds of cold forging parts based on customers' approved drawing. We develop and produce product molds by ourselves. The annual production capacity for cold forging claw pole reaches to 8,000,000 sets.
We have two South-Korean precision production lines, large-tonnage forging machines 9 sets imported from oversea (Japanese AIDA 400 ton, Korean Seoul Press 400 ton, Korean KNUCKLE 650 ton, Russian press 630 ton), punching machines 2 sets (Japanese AIDA 100 ton, and Korean DONG SHIN 600 ton), pre-treating line, heat treating furnaces 5 sets, Daewoo CNC 8 sets, Japanese sawing machine, advanced physical and chemical test, and testing facilities. We passed TS16949 certificate.
We are supplying for GM in Shanghai, Beijing Hyundai, Beijing iljin (steering ball joint product), Chinese OEM Chery Automobile, Chinese OEM Great Wall Automobile, Italian Brembo (brake caliper piston product), Korean Erae Automotive (claw pole and magnetic core products), Japan, Korean Mando (steering-gear spherical housing and blank product), Korean Taeyang Metal Industrial (steering-gear spherical housing and blank product), Korean Sang-Shin Brake (brake caliper piston and steering-gear spherical housing blank products), etc.
We are expecting to establish a business relationship with you in the future and realize win-win cooperation.
Cold extrusion features a massive forming process to produce both hollow and solid blanks in a multistage production process (multistage pressing).Presses with a very high closing force carry out cold forming of the material under a high pressure until the desired shape is achieved.
The material is extruded there by application of a high pressure. An upper die presses the blank through a forming and cross-section-reduced die orifice - the mold.
Longkou Dayuan, is able to make products with complicated geometry and a high forming degree.
Advantages of cold extrusion process:
high dimensional stability
excellent surface finish
continuous fiber flow line thanks to forming
efficient process for mass production
