Custom Plastic Tank Mold involves the resin or liquid being placed inside the mold and then rotated at high speeds. The liquid then evenly covers the entire surface of the mold to create a hollowed part with all the walls evenly thick. After the mold is cooled and the liquid plastic has taken its new form it is then taken out of the mold. This Custom Plastic Tank Mold is very material efficient and very little goes to waste making it more economical and environmentally friendly.
