NPE2018 Post Show Highlights 28 MoldMaking Technology —— AUGUST 2018 By Christina M. Fuges Moldmaking on Full Display at NPE2018 Collaboration is the name of the game, as more than 60 North American mold builders showcased their capabilities in shared demonstrations across the show floor. Burteck is getting into liquid silicone rubber molds, and the shop used NPE2018 as an oppor- tunity to showcase what it can do. The demonstration was a 2+2 Polycarbonate/LSR overmold. The first shot used a four-drop, MoldMasters direct-gated hot runner system. A servo-motor index plate transferred the part 90 degrees to the eject position, where the second-shot molded parts were stripped off and then rotated another 90 degrees to put the first-shot parts in position for the overmolding. This is simulta- neous injection using a standard injection-molding machine with a center inject for the first shot and Kipe MicroDeck for the second shot—a cold deck married up to a servo-driven injection plunger. Burteck is getting into liquid silicone rubber molds, and the shop used NPE2018 as an opportunity to show- case what it can do with this LSR medical demo part. C ollaboration was the key takeaway from NPE2018 for the MoldMaking Technology (MMT) team. Mold builders did not confine themselves to the traditional role of working solely at their booths. Instead, they partnered with other companies in multiple booths to showcase their wares. The MMT team counted more than 60 North American mold builders who exhibited, and that is a big number compared to NPE2015. Collaboration was everywhere on the show floor among mold builders, molders and molding machine manufacturers who demonstrated molds, tooling, hot runners, mold components and processes. Here is just a sampling. VIDEO Access the related video under the Videos tab at MMT online.
