Casting Machines
WORSWICK produce both the conventional straightline (inline) type casting machines and also our unique rotary casting machine which is ideal if space is limited in a plant.
More information on the types of casting machine we offer can be found below.
ROTARY CASTING MACHINEWORSWICK rotary ingot casting machines are widely accepted for their efficiency, low maintenance and ease of operation. When metal is supplied from either a tilting furnace or metal pump it is a relatively simple and inexpensive matter for WORSWICK to engineer a completely automatic feed control, thus eliminating constant operator attention. The variable speed continuously rotating mould table is centrally supported by a heavy duty – low friction bearing ensuring life long smooth vibration free service. Mounted on the table are the internally water cooled moulds, each of which can be quickly and easily levelled in two planes and can be quickly changed when two or more ingot shapes are to be produced. Reversible moulds with two different cavities are also available. |  | |
 | STRAIGHTLINE (INLINE) CASTING MACHINEWhere space requirements dictate a straight line chain conveyor type casting machine, or for those customers who prefer the classical approach to ingot casting, WORSWICK produce a range of inline casting machines which include the advanced features evident in the whole range of WORSWICK equipment which have resulted from over 50 years of experience within the foundry equipment environment. The machines are manufactured with a very robust frame and drive mechanism and, with sealed wheels on high quality matched length chains, the machines are well equipped for the rugged casting environment. The WORSWICK proven system of pouring a number of moulds simultaneously with accurate control of the volume of metal poured into each mould ensures minimum dross formation and consistent ingots. |
SOW / JUMBO CASTING MACHINEThe WORSWICK rotary type sow / jumbo casting machine retains the same basic design principles as our proven ingot casting machine to give smooth vibration free operation. Casting machines can be supplied for either ‘batch or continuous’ production with mould table diameters varying between 4.5 and 8.5 metres. Fully automatic continuous production from delivery of molten metal from the furnace to removal of solidified sow by fork truck or crane from the storage conveyor can be offered. The fully automated system comprises mould table complete with a set of water cooled moulds each fitted with hydraulically powered sow ejector pins, an automatic metal feed unit, a sow/jumbo removal and transfer unit a sow storage conveyor having a capacity of 7 sows with longer versions available. |  |
| Alternatively semi-automatic production can be offered as a less expensive option which requires operator control and removal of the sows from the moulds utilising ‘cast-in’ hooks by means of an overhead lifting device supplied with the casting machine, or using an existing shop crane. The semi-automated system comprises mould table complete with a set of water cooled moulds (or non-cooled moulds for intermittent small batch production) a set of ‘lifting hooks’ for sow extraction, an automatic metal feed unit and an operator controlled sow extraction/removal unit. |
BALL / STICK CASTING MACHINEContinuous production of up to 1500 kg/hr of balls or balls/sticks having consistent weight is available by means of the proven WORSWICK rotary casting concept with internally water-cooled moulds. NUGGET CASTING MACHINEContinuous production of high quality de-ox aluminium nuggets ‘flash/tail free’ having consistent weight, by means of the proven WORSWICK rotary casting concept with internally water-cooled moulds. |  |
GRAVITY DIECASTING MACHINES
WORSWICK manufacture a range of gravity diecasting machines, from single station machines for the production of small parts, up to large rotary multi-station carousel type machines with automatic metal feed, automatic casting extraction and quick die change facilities.
The majority of applications are for the mass production of automotive parts for instance, brake cylinders, engine mountings, thermostat housings, cylinder heads, engine blocks, road wheels and gearbox casings etc. In all cases, the die operation is by hydraulic cylinders, totally relieving the operator of the task of opening and closing the die parts. The control of the die opening and closing is either by means of a mechanical cam system on the simpler smaller machines, or by individual PLC’s on each die, which are networked into a central control PLC on the larger machines.
The more complex machines also have the facility to register when a particular die has been placed in position on a machine and keep a log of the production from that die and the other dies mounted on the machine during any period that the machine is in use. All the multi-station rotary machines have facilities for ring mains for gas and air for die pre-heating and many also have the facility of cooling circuits of certain parts of the die when required.
