Retractable-Tiebar Machine Is ‘Americanized’and Toggle Presses Get Upgrades
At an open house last month, HPM Corp., Mt. Gilead, Ohio, announced improvements to two injection machine lines. First, the original design of the company’s NextWave two-platen, retractable-tiebar presses has been “Americanized.” HPM acquired the design when it bought Hemscheidt of Germany in 1997. Second, in response to customer feedback, HPM has made about 20 modifications to its economically priced universal toggle machines. More than 100 of these presses have been sold since their introduction at NPE ’97. Both machine lines will be displayed in June at NPE 2000 in Chicago.

An injection molding robot is no better than its end-of-arm tooling (EOAT). All the potential benefits of robots--increased productivity, quality, and safety, as well as reduced scrap--are influenced by the effectiveness with which the EOAT does its job. End-of-arm tooling may perform tasks as simple as sprue picking and demolding or as advanced as degating, insert loading, parts reorientation, and assembly.

DVDs are casting a new light on optical discs--quite literally, since new generations of high-density disc players are expected to use blue-green lasers with shorter wavelengths in order to read the smaller pits of new higher-density data discs.

What suits these resins particularly to TP composites is their unusual ability to depolymerize in the melt phase, followed by very rapid rebuilding of molecular weight as the resin cools.

Read MoreRotating & Shuttling Molds Speed EPS Molding With Inserts
Expandable polystyrene bead molding equipment has taken on a new look in order to keep up with the need for faster insert molding. Machine builders say insulated concrete forms (ICFs) are one of the fastest growing EPS applications in North America. EPS shapes act as the forms into which concrete building foundations are poured. Plastic inserts act as spacers to hold apart the two sides of the form. After the concrete sets, the wall is now thermally insulated by the EPS, which is held in place by the inserts.
