Wide range of machinesand applications5/01, 5/04 and 5/05The range of MTT Vacuum Casting machines includeschamber capacities from ~500mm³ up to severalcubic meters.All feature PLC control and options include:• Nylon casting module• Heated Cup for wax masters• Vario Vac technology to aid moulding of viscous materialsTypical applications include:• High quality prototypes for product design verification• Small batch production for bespoke products• Functional Nylon components in a range of grades –particularly good for living hinges and high strength• Automotive ‘hot test’ and specialist manufacture• High quality wax masters for investment casting• Soft feel components using Vario Vac technology• Production of EP tooling resin mouldsPlease see product specific brochure for full rangeof machine sizes.09
Prototype and batch production thermoplasticinjection mouldings from low cost mouldsMTT 100 KSA Semi AutomaticInjection Moulding MachineDesigned for low cost tooling in either Aluminium or epoxy resin the 100KSAoffers a versatile platform for components from 0.5 grams up to a maximumof 180 grams depending on configuration.Capable of providing 20 Tonnes of clamp force the 100 KSA relies uponmanual mould insertion followed by an automatic moulding cycle, providinggood process stability. Alternatively the moulding cycle can be run manually,particularly useful when setting up moulding parameters. A range of plungersizes is available for different shot volumes and injection pressures.It is ideally suited to batches of 50 to 1000 and can also be used forover-moulding inserts.MTT EP Tooling Resinfor rapid toolingA low cost alternative to hard steel tooling. EP tools are produced by ‘casting’two halves of a mould against a master model in a similar way to the siliconetools used in Vacuum Casting.The major difference is that the first half of the mould is cast against a mastermodel set in a split line face. The second half is then cast against the first halfwith the master model positioned in the cavity.Major advantages include significantly reduced lead times and the abilityto replicate complex geometries and surface features. It is also possible tocreate side actions for hidden features. A common practice is to create hybridtools that include metallic components that are cast in when the mould isproduced. EP resin can also be used on conventional moulding machines.10
