This machine features a temperature controlled heating barrel, rack and pinion injection ram, over centre mould closing, automatic moulding ejection and is supplied with a wheel mould (flat upper & shaped lower mould) and 2kgs of red polystyrene granules. To operate the machine, plastic granules are loaded into the heating barrel. After a short pre-heat time, the plastic is ready to inject. The mould is closed and the injection ram lowered. This action automatically opens a valve in the injection nozzle and the plastic is injected. Once the mould is full the ram is retracted. The heating barrel rises on its return springs, closing the valve. After cooling the mould is opened and the moulding is ejected by pins in the mould cavity. Requires permanent fixing or bolting down. Safe and easy to use.
The R25 is an industrial quality plastic granulator. Suitable materials for recycling include PP, HIPS, ABS and LDPE. Materials to be granulated are loaded into the hopper at the top of the machine. A combination of static and rotating blades gradually chops the material into smaller and smaller pieces. Once the material reaches a small enough size it passes out through a mesh filter and into a collection bin. This model is the 3phase version. When not in use, a lockable cover can be fitted over the inlet chute, ensuring that no unwanted debris enters the machine. The Process: Wash out your old cartons Shred them in the R25 Schredder, reducing their volume by 95% and creating a usable material. At this stage, you can choose to put the waste for normal recycling, or to re-process it within school, in either of two ways: Use it directly in the CR Clarke 25 Injection Moulding Machine. (490-170) Heat it on a mould-plate and then roll it into a new sheet using the R30 Sheet Press (490-048).

A combination of static and rotating blades gradually chops the material into smaller and smaller pieces. Once the material reaches a small enough size it passes out through a mesh filter and into a collection bin. The cutting blades are powered by a three phase motor fitted with a phase inverter, allowing operation from a normal 230V electrical supply. When not in use, a lockable cover can be fitted over the inlet chute, ensuring that no unwanted debris enters the machine.

The R30 Sheet Press converts granulated thermoplastic material into a usable form using heat and pressure. As standard, the formed article is a flat plastic sheet, which can typically be used for vacuum forming, laser cutting, line bending etc. There are also tools available for making shaped parts, for example Frisbees, on the machine. A removable material cassette is loaded with granules of the material to be pressed. For best results the granules are sprinkled uniformly over the base of the cassette. The cassette is then loaded into the R30 sheet press, and clamped firmly between two temperature controlled aluminium hotplates. The heat and pressure causes the material granules to soften and fuse. At the end of the pressing cycle, the material cassette is unloaded and allowed to cool. The formed sheet of material can then be removed and used. As standard the R30 produces a sheet 457 x 305mm (compatible with the 725FLB vacuum former).
