Components

Mold head

Center feed mold head

Mold opening and closing mechanism

Mold opening, closing and mold shifting system: The center clamping structure of the crank arm has a strong clamping force and the mold plate does not deform. The mold opening, closing and mold shifting are double linear guide rails, which are easy to move and have little resistance. (The mold is shifted into place by the hydraulic brake cylinder control without impact vibration)

Electric box

All major electrical parts are made of components imported from Japan and Taiwan to ensure stable machine performance.

Intelligent microcomputer control system

Controlled by Japanese Mitsubishi PLC computer and human-machine interface (Chinese or English), operated by touch screen. All process settings, changes, retrieval, monitoring, fault diagnosis and other functions are realized on the touch screen, with point-free contact working principle and durable components.
