Bakelite product is made by two ways. One is compression molding and another one is bakelite injection molding. The cost of Bakelite compression molding is lower than injection molding, but compression molding cost more in labor and has lower precision and rate of finished products. Compared with Bakelite compression molding,bakelite injection molding need more cost in moulds and machine. But it cost less in labor, high product precision, and high rate of finished product. So gradually, Bakelite injection molding becomes more popular than compression molding.
Injection molding parameters for some common type Bekalite:
Mould temperature | Barrel temperature | Injection Pressure | Holding Pressure | Screw rate | Cooling Time | |
Phenolic aldehyde | 160-180℃ | 80-95℃ | 100-170Mpa | 80-100 Mpa | 40-80 r/min | 15-50S |
Epoxy | 150-170℃ | 80-90℃ | 70-100 Mpa | 40-70 Mpa | 30-80 r/min | 60-80S |
| Polyimide | 170-300℃ | 100-130℃ | 70-100 Mpa | 40-70 Mpa | 60-80r/min | 20-70s |
Melamine resin | 150-190℃ | 80-105℃ | 60-80 Mpa | 40-70 Mpa | 40-50 r/min | 15-40S |
Bakelite is widely used for its extraordinarily high resistance - not only to electricity, but to heat and chemical action in electrical insulators, radio and telephone housing, kitchenware, jewelry, etc..
