A new range of accumulator die heads, recently released by Graham Engineering Corp of York, PA, USA enables manufacturers to save money through rapid colour and material changes in extrusion blow moulding processes.
Graham Engineering Corp, a global leader in extrusion blow moulding equipment has released accumulator die heads that allow manufacturers to quickly reconfigure their blow moulding machines, enabling them to save resin, a significant manufacturing cost component and offering a very fast payback on their investment.
Manufacturers are liable to lose hundreds of dollars while a machine is purged for hours to change colours and materials. Accumulator die heads enable rapid colour changeover for extrusion blow moulded industrial parts.
With GEC accumulator die heads, the change process takes only 30 – 60 minutes compared to conventional options that may take up to 12 hours to purge from one colour to another. GEC heads do not require regular purging due to the rheologically-efficient head design.
Key features of GEC accumulator die heads:
- Available in a range of shot sizes from 2kg to 30kg to fit multiple applications
- Can be retrofitted to existing machines from other suppliers
- Die heads are suitable for use for running olefin resins such as HDPE, HLMIPLE, PP and LDPE or engineering resins such as Noryl ABS, PC/ABS polyurethanes or acrylics
- Die heads can run glass or talc-filled resins
- Die heads utilise a rheologically-efficient diverter to provide wear resistance through hardened D2 diverters with highly polished flow surfaces featuring ‘first in, first out’ flow design
- Designed to allow operators to complete a manual cleanout in less than one hour with simple hand tools
