The injection machines is a rather fast machine that allows for productions of very precise objects. Moulds can be slightly harder to make but once you have a good mould you will be amazed by the products you can make. The injection machine can usually make smaller objects depending on the barrel’s volume but operates at faster speed and with high precision. The output colour is often unpredictable when mixing colours in the barrel allowing for surprising patterns that can add to the beauty of your products.
