They are mainly used for forming a class of thermosetting plastic mold,
its corresponding device is a pressure molding machine. Compression
molding method according to the plastic properties, the mold is heated
to a forming temperature (typically 103 ° -108 °), injection mold maker and then a good
measure pressure plastic powder into the mold cavity and the loading chamber,
closed mold, high fever, high pressure in the plastic viscous flow was
softening, after a certain time curing stereotypes, shape into a desired
product. Pressure injection molding and compression molding is
different from a separate feed chamber to the mold is closed before
molding, the plastic in the feed was preheated Interior Finish viscous
flow state, plastic rattan garden furniture mold extruded under pressure to adjust the mold cavity and
hardening the molding.
