A single sinuous electrical resistance heater is cast in situ into the ribs of the grid melter. The underside of the grid melter is provided with recesses which function as accumulators to prevent the buildup of pressure on the underside of the grid melter upon remelt of solid thermoplastic material located above the level of the top of the grid melter.
