High pressure green sand moulding
FTL's Moldmaster high pressure green sand moulding machine continues to lead the field today as it has over the past 20-30 years. The Moldmaster produces moulds of high uniform density and rigidity resulting in sound, accurate castings to meet today's demanding market. The latest machines include state of the art hydraulics, weighing and PLC controls to maintain high productivity and reliability.
FTL has taken the well-established Moldmaster high-pressure, greensand, moulding machine and adapted it to meet the exacting requirements of today's high-production iron founders. The four-poster design employs multiple squeeze feet, each with its own independent hydraulic cylinder. This arrangement allows the sand to be moved around as it is compacted, to suit the pattern contours. Vertical and horizontal faces are rammed hard with only a few points variation over the whole mould. Inner and outer feet are separately controlled, hydraulically, for higher pressure along the box wall.
The Moldmaster is available in a number of variants, including two and three station layouts, duplex Moldmasters to suit smaller box sizes, rotary indexing machines, and in-line Moldmasters for high output rates on a single-pass line. A jolt facility can be incorporated to cater for deep pattern cavities which can be programmed on or off as required. The rigidity of Moldmaster moulds allow large, deep cods to be stripped without support or rolling over. Previously cored parts can be moulded, reducing costs and manning, and casting weights can be reduced maintaining tight mould tolerances and rigidity.
