Luoyang Super League forging forging tells you the type and characteristics: at low temperature forging, forging dimensional change is small. At 700 ℃ the following forged alloy cylinder block, less oxide formation, and no surface decarburization. Therefore, as long as the deformation energy in the energy range of molding, cold forging easy to get a good dimensional accuracy and surface finish. I have a company with high quality steel forgings mainly to undertake processing, etc., set design, development, sales of professional forging enterprise, you are welcome to inquire. Blank when the cold deformation and work hardening, so die withstand high load aluminum block, therefore, require the use of high strength die and prevent wear and bonded using hard lubricating film treatment. Also car block material, in order to prevent the blank crack, intermediate annealing to ensure that the needs of deformation when needed. In order to maintain good lubrication of the cylinder, the blank may be phosphate treatment. When working with a continuous bar and wire rod, the current section can not be lubricated process, is studying the possibility of using phosphate lubrication method. Aluminum block | Jiaozuo cylinder | Preferred Super League Super League forged by the Luoyang Forging Limited. Luoyang Super League Forging Co., Ltd. (www.lysmzg.com) (www.lysmzg.cn) strong, credible, in Luoyang, Henan Province forging industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Super League forging into the brilliant and you work for a better future!
