不要陷入“闪速短裤”追逐中

Injection molding’s most common defects can have inverse correlation, where correcting one causes the other, leading to the“chase.”

Follow These Tips to Sanitize 机 Controller Screens& Buttons

Keeping your workers safe from the coronavirus makes it extremely important to institute a sanitizing procedure on all touch surfaces of the controller, screen and operating panel. I did some research and here’s what I found.

搜索通用设置表

Duplicating a process from one injection machine to another is frustrating and time-consuming. Develop a mold-specific setup sheet that works in all kinds of presses by differentiating plastic parameters from machine parameters and duplicating those plastic conditions from machine to machine, electric or hydraulic.
