Moulding by hot pressing
Nettet14. nov. 2013 · A Gen lab 3.5 kW hot air oven was used for preheating the preform (Glass/PP wrapped-plain-woven plied structure). Fabric samples were cut into 12 × 12 cm size. Nine layers of such samples were considered as the final preform. Subsequently, the mild steel mould is fabricated to fit with the hydraulic moulding press. NettetHot pressing is a manufacturing process for predominantly thermosetting (fibre-reinforced) plastics for the production of 3D geometries. The curing process takes place in the press mould under high pressure and at high temperature. Alba offers the most appropriate mould technology for the process and material used.
