EPS beads before joining mould, need to predict the bubble of probability, make bead expansion to a certain size.

Pretest bubble process determines the density, dimensional stability and precision of the model, is one of the key links. Suitable for foamed EPS beads there are three ways: to predict the probability of pretest bubble hot water, steam bubble pretest probability and vacuum bubble. Vacuum pretest bubble bead high foaming rate and bead dry, use more.

(2) curing

Bubble pretest probability of EPS beads placed in dry and ventilated warehouse within a certain period of time. In order to make the pearl foam pore pressure balance, make the bead with flexibility and expansion ability, remove the beads in the water again. Curing time at 8 ~ 48 hours.

(3) foam molding

Soak pretest probability of maturation and EPS beads filling into metal mould cavity, heating, make bead expansion, again filled the space between the beads, and make the bead between mutual confluence, to form a smooth surface, namely model. Must be conducted before the mold cooling, cooling the model below softening temperature, hardening model, after setting to the mold. Shall also have the model after the mold drying time and size stability. Equipment has a steam cylinder and automatic forming machine two.

Learn wisdom by the bubble plastic sheet production: bubble plastic plate, wire cutting, binding - model

This simple model, you can use the resistance wire cutting equipment, foam plastic cut into the model.

Complex models using resistance wire cutting device, first of all, the model is divided into several parts, and then stick with, so that it is the entire model.
