ZEISS COMET L3D 2 Thermoplasঞc Composites at NPE2018: Machinery and Equipment Injecঞon molding machinery supplier Arburg displays its hybrid process called fiber direct compounding. By Jeff Sloan CompositesWorld Increased use of thermoplasঞc composites will, almost certainly, depend on machinery and manufacturing processes that can make it adaptable for high-volume, high-speed ap- plicaঞons. Several equipment suppliers are leading the charge and have technology at NPE2018 highlighঞng capability. Four manufacturers have been parঞcularly acঞve in developing systems that adapt tradi- ঞonal plasঞcs processes, like injecঞon mold- ing, to integrate use of conঞnuous fiber pre- forms. At NPE, KraussMaffei's (Booth W403) process, FiberForm, is being demonstrated in combinaঞon with swivel plate technology for mulঞ-component injecঞon molding on a GXW 450-2000/1400 machine. FiberForm combines the thermoforming of composite sheets and injecঞon in a single molding pro- cess. The resulঞng fiber-reinforced plasঞc components are parঞcularly lightweight, but offer strength made possible by conঞnuous fiber reinforcement. Paul Caprio, president of Kentucky-based KraussMaffei Corp., notes, "Our customers appreciate the high quality, reliability and cost-efficiency when manufac- turing fiber-reinforced lightweight compo- nents in large quanঞঞes and fast cycle ঞmes." Engel (Booth W3303) is similarly combin- ing conঞnuous fiber preforms with injecঞon molding to create high-strength, high-volume hybridized structures. Engel recently worked with CCP Gransden to adapt an Engel vduo 1100 workcell for high-volume composites manufacturing. The workcell combines ther- mal-press forming and injecঞon molding to achieve single-stage composite overmolding. thermal press forming process, the injecঞon molding unit simultaneously injects a shot of thermoplasঞc resin. CCP Gransden has worked with PEEK, PEKK and PA. Injecঞon molding machinery supplier The process begins with a reinforced thermo- plasঞc blank (organosheet) that is heated in an infrared. The heated blank is then trans- ferred to the press tool using a mulঞ-axis robot. When the press closes to complete the Arburg (Booth W1325) is featuring another hybrid process, called fiber direct compound- ing (FDC). The FDC unit on the injecঞon unit includes a side feeder through which conঞn- uous glass rovings enter the barrel. The rov- ings are cut by an integrated cuer and then enter an adapted cylinder featuring a special- ized screw. The fiber length, fiber content, and material combinaঞon can be adjusted to targeted specific component properঞes. At NPE, a hydraulic Allrounder 820 S is produc- ing two 11.6-oz airbag housings in a cycle ঞme of 70 seconds. A weight monitor inte- grated into the automaঞon system displays the consistency of the shot weight and the finished parts are placed in boxes by a Mulঞ- li[ V linear roboঞc system. Roctool (Booth S17013) offers several products, based on its inducঞon heaঞng technology, designed for use in composites fabricaঞon, mostly targeted toward the high- speed/high-volume consumer electronics market. Light Inducঞon Tooling (LIT) uses shell tooling with inducঞon heaঞng which allows high heat and cooling ramps while maintaining high temperature uniformity on the mold surface. Inducঞon Dual Heaঞng (IDH), developed with Arburg, offers induc- ঞon-based mold heaঞng for overmolding of carbon fiber preforms. 3iTech Heat & Cool helps ease design of mold heaঞng and cooling layout to provide fast and homogeneous heaঞng. The system uses flexible inductors that allow designers to follow any shape of tooling, using standard steel or Invar. A high-frequency current runs through the in- ductors to heat up the mold surface. Standard cooling channels with water are used to re- duce mold temperature.
