The injection moulding compounder (IMC) stands for innovation and a good return on your investment. It's groundbreaking engineering, successfully teaming up a continuous extrusion process with a discontinuous injection moulding process. It stands for a high return on investment - due to generally superior product properties and substantial savings in raw material costs. KraussMaffei's IMC was the first time compounding and injection moulding had been successfully yoked in a one-stage process. Since the IMC was showcased at the K1998, KraussMaffei has continued to develop and refine the process and to adapt it to new application areas.

The injection moulding compounder offers striking cost and quality advantages. It cuts the cost of materials, improves product quality, delivers high plasticizing performance, and by opening the way to customized compounding, it increases production flexibility and opens up new application areas.

The Injection Moulding Compounder with its integrated twin-screw extruder achieves hugely increased throughput because plasticizing takes place continuously. The biggest advantage over traditional injection moulding machines is that processors can do their own compounding, ie, start with the basic HDPE and then add fibres, fillers or masterbatch during processing. Since it’s much cheaper to buy individual raw materials than ready-made compounds, this has a dramatic impact on costs. Using an IMC to make pallets slashes costs relative to conventional production methods – among other things, because it’s possible to raise the proportion of wood flour, rice husks or other fillers to over 50%. Low-cost materials can replace a high proportion of the high-cost polymer. Further savings result from shorter throughput times due to
the lower-temperature melt requiring less cooling.

Plastic pallets last 15 times longer
Cost-for-cost, a filled HDPE pallet made in this  way lasts 15 times as long as a wooden pallet. This cuts the ratio of waste to pallets in circulation. Plastic pallets are immune to fungal infection and, unlike many wooden counterparts, they are not subject to import restrictions and will also meet high hygiene requirements.

If the pallets are made using recycled materials, a degassing stage removes the volatiles from the material during extrusion. Additionally, injection moulding compounding also offers a whole swathe of additional design possibilities that cannot be achieved with wood. There’s also the option of making complex structures that look like wood.
