After making the prototype, we can take step forward for Prototype mold. It requires very less time to make this mold, with the help of prototype mold we can actually take out samples in required materials (PP, HDPE, etc.) and can get actual feel of samples as we can test them in all necessary means like Physically, Dimensionally, Volumetrically, etc. This is an extra step , only used if the client is unsure about the product.
This is were the need of the above steps , properly done makes the actual difference, it is very time consuming and expensive to make an changes in the multi cavity molds. It is the final mold made with, made after correcting all the flaws and flaunts. Actual production of samples are molded from this mold and submitted to customer as per their requirement.
