The working process of the eps pre expander machine

- Dec 20, 2015 -

Widely used in a variety of precision instruments, all kinds of light industrial products, packaging pads, mostly usingeps pre expander machine, it can be directly made with the corresponding shape of the packaging, with a reliable shock, heat insulation, pressure And other characteristics. The forming process of the plastic packing block can be carried out on the hydraulic press. The molding machine is closed by the hydraulic cylinder of the hydraulic press. The operation is followed by low speed start, high speed, low speed closed mold, closed mold and the last lock is completed by the adjusted cylinder.


When feeding, open the exhaust port, air blow mold cavity, 0.1 ~ 0.2MPa steam preheated cavity 30s, with the feeding gun will eps sent to the cavity, with air from the vent and closed mold Leaving the gap out. Feeding is completed, die closed, and then to the gas chamber through the 0.1-0.2MPa steam heating 10-30min, eps expansion full of mold cavity. Water cooling stereotypes, cooling water spray to the mold wall to cool, and then product stripping, give the drying room in the 50-60'C hot air drying 24h, curing stereotypes.
