Three cutting techniques for thermoplastics: circular cutting, cutting with circular saw, guillotine cutting. Cutting of co-moulding joints, oval and rounds ends.
Plastics can be cut in different ways. The choice of the cutting method relies on the material and the shape of the article to cut. Because of the low thermial conductivity of thermoplastics, the main risk in the cutting operations is that the heat generated by the tool damages the material. Such risk can be avoided using blades suitable to the material to cut.
GS Finishing Machines can carry out the following cutting techniques.
The guillotine system is used to cut extruded profiles made of different thermoplastic materials. It produces cuts that are almost precise, without burrs and shavings.
CUTTING WITH CIRCULAR SAW
The circular saw is used for the linear cutting of sheets or pipes of termoplastic materials. To avoid that the material heats up during the cutting, a high advancement and the correct toothing of the blade are necessary.
CIRCULAR CUTTING WITH COPYING OF THE PROFILE WITH FINGERNAIL-SHAPED TOOL OR WITH REMOVAL OF THE CHIP
The circular cutting is used to cut the ends of thermoplastic pipes.
The articles that we can cut can be produced by means of injection moulding, extrusion moulding, compression moulding, thermoforming, blow moulding, suction 2D/3D (2k) and rotational moulding.
Among the articles cut with the various methods by the customized machines of GS Finishing Machines there are the following, listed as an example: co-moulding joints between co-moulded articles, round and oval ends of articles. The cut of the ends can be oblique or perpendicular to the axis of the pipe and can happen together with the copying of the outer profile of the article to finish.
