Three Layer Board Hot Press Steel Platens Custom Made
Custom Made Three Layer Board Hot Press Platen
Those heating platens due to the big thickness and weight are designed into several small circulations and big size deep hole diameter in order to achieve the fast heating and final temperature uniformity;welding quality have been specially paid attention and any bad weldings with bubbles will not acceptable as they will leak after very short using time.We have the toughest quality control here and every production step shall be well monitored and final surface by surface inspection shall be appliied:
