A number of new mold components were shown at last month’s Amerimold expo in Rosemont, Ill., sponsored by Gardner Publications, publisher of Plastics Technology and Moldmaking Technology magazines. DME Co., Madison Heights, Mich., expanded its MoldBasics line with several low-cost mold-cooling products. These include new hose connectors—sockets, plugs, extension plugs, and replacement seals. They are made of brass and stainless steel and come with Viton fluoroelastomer seals. They complement DME’s Jiffy-Tite line of hose connectors.
Among the new MoldBasics products are SV-Series male plugs with an automatic shutoff stemmed valve, which minimizes coolant loss at the mold. Also new are clampless hose stems for use with push-to-connect/push-to-lock hoses. They eliminate the need for hose clamps.
DME also showed its recently introduced Black and Gold interlocks for shuttle mold bases. These long-lasting interlocks ensure accurate alignment and guidance of shuttle-mold base plates.
In addition, Progressive Components and sister company Roehr Tool exhibited three new products. Progressive, in Wauconda, Ill., showed its new ProtoBridge system for closure molding. It is a standard tooling kit that helps minimize costs of new product development. It can be used with collapsible cores or jump-thread designs and can be converted from one part design to another while the mold is in the press. With four cavities, it can test four different designs at once or can be used for single-cavity development and then as a four-cavity “bridge” mold for early production runs. The system is available for purchase or rental—in the latter case, only the collapsible cores and cavity blocks need to be purchased.
Progressive also introduced improved slide-retention capabilities. Its existing CamActions provide standard components for molding and releasing external undercuts. Now Progressive offers the CamAction 300 and 400 Series with its SRT slide retainers already installed, providing a reliable means of maintaining the slide position during the mold-open stage.
In addition, Roehr Tool Corp., Hudson, Mass., has expanded its range of custom collapsible cores (C-Cores) to include models as small as 10 mm and as large as 200 mm.

When it comes to part design, the importance of a properly designed melt delivery system is often neglected.
