The GG Tech company has many years of experience in the design and production of vacuum molds, used as interchangeable elements of thermoforming and gravity machines used in the casting technique with the use of epoxy resins. Vacuum molds are typical industrial tools, characterized by high wear resistance, while gravity molds are tools for the production of short series of parts, the design of which must ensure adequate venting of the cast models. Considering the large number of projects and molds produced so far, they naturally became a separate product in our company.
