Battenfeld Injection Molding

Each blend was starve fed and compounded on a Haake twin-screw extruder at 150 rpm, using a temperature profile of 475°F, 525°F, 550°F, and 550°F. The compounded materials were dried at 100°C for 2 hr. Each blend was injection molded into flex bars, single-gated and dual-gated tensile bars, and Izod impact bars using a 1.5-ounce Battenfeld injection molding machine. Specimens from each blend were tested for tensile properties at 2 inch/min (50 mm/min), flexural properties at 0.5 inch/min (12.5 mm/min), and impact properties using a 2 pound hammer on an Izod bar.

Most of the compounds were extrusion compounded in a conical, partially intermeshing, counter rotating twin screw extruder (Haake Reomix TW-lOO). The extruder speed was set at 50 rpm and the barrel temperature profile was set to produce a melt temperature of 260°C at the die. Samples were injection molded in a 31.8 MT Battenfeld press with a 59 cc shot size. Where noted, samples were compounded in a 60 cc Brabender internal mixer and compression molded.

Conditions Letdown ratio, 50 1 Battenfeld press, 85 tons Barrel temperature, 230-250 °C. Testing Color data generated from 7.5 cm diameter injection-molded disks and opacity measured on nominal 0.575 mm thick press-outs from the letdowns. 

Injection molding machine (Battenfeld Corp. 250 CDC) was used to prepare the specimens for all mechanical tests. The specimens for thermal conductivity (5cmx5cmxlcm) measurement were prepared by Compression molding machine (Model LP-S-50), Labtech Engineering Co., Ltd. 

Injection moldings were performed on a Battenfeld BA 400 CDC 44 ton injection-molding machine equipped with a 3 cm diameter screw. A 60 second cycle time was used with a mold temperature of 18 °C (64 °F). All heating zones and injection nozzles were set at 232 °C (450 °F).

The Battenfeld Airmould Contour process provides a gas-assist alternative when it is not possible to inject gas directly into the molten plastic, or where moldings with gas channel openings are not desirable. It can be used where parts only require one smooth or high gloss surface with different wall thickness or complex geometry on the other side. The process has gas entering between the melt and mold cavity surface where external pressure is applied to the melt. The gas can be applied within specific part sections. 

Normally, the injection blow molding machines use the horizontal rotary transfer table (Gussoni Method) as Wheaton, Jomar, Bekum, Fischer, and Johnson Controls. Battenfeld Fischer also produced a vertical rotary...
