The processing of high-density rigid polyurethane foam is the result of a long technological evolution. It is a particularly versatile material with a very wide density range from 40 to 400 g/lt. It finds application in many sectors and especially in furniture.
These systems are suitable for the production of parts ranging in weight from a few hundred grams to several kilograms. The resulting artefacts have mechanical characteristics that are very similar to those of real wood and allow for considerable ease in cutting, drilling, assembling and painting either traditionally or with DIP-PRINT technology.
The production process of this polyurethane foam involves the use of epoxy resin moulds, constructed with appropriate metal reinforcement frames. The moulds are normally placed on a rotating carousel and operate at temperatures between 35°C and 45°C.
High- or low-pressure foaming machines (Saip Equipment) are used for the casting phase.
Two different foaming technologies are used: open mould technology and closed mould technology (by injection).
