Q. What do you mean by Compression moulding?
In compression molding, a material normally in power or perform shape , is loaded directly into the hot die cavity, pressure from 150 to 700 kg/cm2 is applied , held for a curing period and then the finished part is ejected. Press stays closed while the heat cures hardens and sets the plastic part. The time for curing depends upon the design, small thin-wall pieces require as little as 20 seconds. The curing temperature is to the order of 200 C. Compression molding is largely utilized for molding thermosetting materials.
A measured amount of power plastics is placed in the power female cavity continuously heated by steams or electricity. The movable bolster is raised so that the female mold portion contacts the male die which also is heated. The combined effect of temperature and pressure causes the plastic to flow into the mold cavity.
