In this stage, we generally use high-performance #Polyurethane materials. Casting urethane is a delicate process and for this reason, each and every procedure must be followed carefully as stated in the recipes in order to refrain from making any mistakes. #ABS, #PMMA, #PP, #PA, #Glassfilled, and #PC are only some of the materials we can simulate in this process. The correct ratio must be used when these materials are mixed together. After #polyol and #isocyanate are mixed in the pot, the liquid #resin will be poured into the cavity of the #Siliconemould via hoses under a #vacuum environment and with the help of gravity. When the materials are mixed, a chemical reaction occurs which transforms them to solid form. It must be taken into consideration that it is sure to shrink as it becomes solid, though it is generally a relatively minor amount of shrinkage. Approximately 10-20 minutes later, #mould will be ready to be cured in the oven. Basically, we put the mould in a temperature controlled oven and wait for at least 2 hours. Cycle time depends on the material we use and the post-process requirements to fulfil our client`s needs. Now, we should demould the part and prepare the mould for the next shots and repeat Stage 4. This process can be repeated up to approximately 20 times.
