Graham Engineering Corp (GEC), represented by HBM Packaging & Plastics Technologies in Oceania, has invested in colour-change technology for their extrusion blow moulding equipment that drastically reduces the time needed for colour changes.
Graham Engineering Corp has changed from pellet concentrates to liquid colours on their large extrusion blow moulding machinery and equipment.
The GEC accumulator head allows for colour changes in as little as 1 hour, compared to other blow moulding machines where colour changes can take 8 -12 hours.
The time-savings are due to the advanced overlapping spiral-diverter designed accumulator head. The colour change technology allows white to black colour changes in six shots and black to platinum colour changes in 30 shots.
Graham Engineering Corp has recently installed an accumulator head blow moulding machine with fast colour change capability for Hayward Pool Products Inc in North Carolina, USA.
“The fast colour change capability of the Graham machine was a key selling point” said Scott Pugh, Hayward’s Manufacturing Manager.
The machine has 140 tons of clamping force and an independent servo platen control and is being used to mould various sized filter tanks at the Clemmons plant in North Carolina. The accumulator head blow moulding machine features a 200mm bore grooved extruder with a 23Kg shot head.
“Moving to liquid colours, and upgrading with the new GEC blow moulding machine has helped us make faster colour changes and practice lean manufacturing principles,” Pugh said.
