In wave-type highway guardrail system, there are several relatively complex metal parts such as connector between W beam and concrete, connector between W beam and thrie-beam, connector between W beam and concrete, Bull nose, Fishtail, unlike W beam or thrie-beam can be roll formed, they are produced by special hydraulic pressing. To get satisfactory parts by pressing, the technology of mould building is important, a slight deviation on the mould(s) may cause incorrect shape. Secondly, the sheet metal shall be cut at accurate dimension, too small in length or width is not good, but excess metal would cause creases as well. Therefore laser cutting is generally suggested.


In addition, we developed a punching technology on slope surface which enable us to produce such kind of products the best in the world, or one of the best in quality but with the lowest price. If not without the punching technology on slope surface, the location of the pre punched holes on the metal plate would change after press forming due to metal stretching. We have reached an cross-licensing agreement with a famous metal fabricator for wind-wind relationship.


The jobs of hydraulic pressing and punching on slope surface above described require adequate patient, trial and error are needed to repeat many times. Only the mechanical talents who know the metal properties and understand how to control the deformation of the metal possess the confidence to persist till final success. We are prepared to provide professional service to those who are in need of the metal product requiring hydraulic pressing and/or with creative technology.
