Injection moulding is a process for the sequential production of one or more three-dimensional thermoplastic parts. The plastic (possibly together with additives such as masterbatches) is transported from the hopper of an injection moulding machine by means of a rotating screw. The components are melted, homogenized and conveyed to a nozzle at the cylinder end where a melt cushion is built. The nozzle is opened and the screw is pushed forward to inject the material into the mould. The injection pressure ensures that the cavity fills completely. The tool opens as soon as the plastic has reached sufficient stability to allow the part or parts to fall out or be removed. At the same time, the machine conveys more material down the screw ready for the next injection shot.
FKuR's product portfolio includes a large number of injection moulding grades that are biobased and in part also biodegradable or industrially compostable.
