Rapid Low-Pressure Prototyping (Low Volume Production) With Reaction Injection Molding By Nice Rapid | May 03 , 2020 The low pressure prototyping technology(Low Volume Production) is to produce silicone mold under low pressure conditions with prototype (such as: rapid prototyping pieces, samples, prototype sample), and cast with PU materials under low pressure conditions, thereby clone the replica same as the prototype. The low pressure molding technology can be applied to production in small batch injection molding with changed material of product prototype and assembling prototype so as to meet the requirements of performance test in the process of product development, marketing, inspection, examination and approval.
