low volume production prototypes by vacuum casting/low volume production by RIM

Prototyping is to make one or several products according to drawing , without making the mould. Prototype is mainly for checking the appearance or function before production.Usually when a product design finished, it needs to make the prototype. So prototype is the first step to verify the feasibility of the product.It is the most direct and effective way to find defects, product design deficiencies and shortcomings.So as to make improvement, until not find any defects from individual prototype. At this point, usually require small batch trial and then find out the deficiency in the batch to be improved.
