Advanced Manufacturing 34 MoldMaking Technology —— AUGUST 2016 the post-production conditioning by combining foaming with rapid mold heating and cooling. Unlike traditional solid-part molding where the material sets up or freezes when it makes contact with the cooler mold surface, heating the mold to near the melt temperature allows This table shows the degree of expansion with physical foaming technology in relation to part stability/stiffness (blue bar) and part weight (orange bar). the material to stay molten longer and results in a resin-rich, smooth surface to the molded part. This general process of heating the mold surface prior to or during injection and then rapidly cooling the mold has many terms, including variotherm, rapid heat cycle molding (RHCM) and hot/cold Marposs Diamond systems redefi ne the rules of on-machine tool measurement, where precision requirements are pushed to the limits daily. VTS, the Diamond Visual Tool Setter, is ideal for measuring micro-tools used for mold production, guaranteeing high cutting precision and production optimization.

A foamed core prevents sink marks, and ball-filled-mold technology produced the glossy surface with no visible weld lines.
