Record number: 2, Textual support number: 1 CONT

Hot runner molds. Thermoplastic runners are reground and reused. A logical extension of the three-plate mold overcomes this and is called a hot runner mold. This mold has a hot runner plate, which is a block of steel heated with electric cartridges, thermostatically controlled. This keeps the plastic fluid. The material is received from the injection cylinder and is forced through the hot runner blocks into the cavities. It is a more difficult mold to build and operate than a three-plate mold, but produces parts less expensively on longer-running jobs.  3, fiche 2, Anglais, - hot%2Drunner%20mould

Parts made from partially crystalline engineering polymers should preferably not be made by hot runner injection moulding if a perfect surface finish is essential. It is advisable to make use of a subsidiary runner, which thermally isolates the nozzle from the moulded part, thereby reducing the risk of surface defects.  4, fiche 3, Anglais, - hot%20runner%20injection%20moulding

Record number: 3, Textual support number: 1 OBS

Runners can be classified into two types, namely the cold runner and the hot runner. The mold temperature for the cold runner is similar to the mold temperature for the cavity. The material in the cold runner will eventually solidify, and be ejected with each cycle. The hot runner maintains the polymer at a melt temperature, either by insulation or by heating. This keeps the material fluid. Hot runners are not ejected with each cycle.  5, fiche 3, Anglais, - hot%20runner%20injection%20moulding

The technique used to partially clear the resin from the injection nozzle after the injection cycle. By pulling the screw rearward, the resin is drawn back into the injector.  2, fiche 4, Anglais, - suck%20back

Record number: 4, Textual support number: 1 CONT

Most machines retract the screw slightly at this point to decompress the material to prevent drooling out of the nozzle. This is called the suck back and is usually controlled by a timer.  3, fiche 4, Anglais, - suck%20back

Record number: 4, Textual support number: 1 OBS

When the pressure on the sprue is not held long enough for the resin to cool before the screw returns, some of the hot resin in the cavities or runner system may expand back into the nozzle and cause sink marks on the finished part.  4, fiche 4, Anglais, - suck%20back

Insulated runner molds. A combination between a hot runner mold and a three-plate mold is called an insulated runner mold. The gating system is very similar to that of a three-plate mold except that the runners are very thick, at least 1 3/4in.(45mm) in diameter. There is no runner plate, and the backup plate and A plate are held together by latches. After the material is injected, the outside of the runner freezes but insulates the center, permitting the core to remain fluid at molding temperatures and act as a hot runner.  1, fiche 8, Anglais, - insulated%20runner%20mold
