EX series injection moulding machines - Eram Holding Group

Fastest dry cycle times and utmostprecision – EX injection moulding machinesPackagingKraussMaffei’s EX series of all-electric machines arehigh-performance, high-precision machines with thefastest dry cycle times in the industry. At the heart ofan EX machine is the unique Z toggle that is responsiblefor delivering this speed and performance.Together with the direct-drive electric injection unit,this engineering concept guarantees outstandingprecision and highly responsive machine dynamics.

Innovative clamp design with Z togglecirculating oil lubrication. There’s no risk ofthe production area being contaminated withlubricant.is a movement profile with very tight tolerances.Generous daylight between the tiebars makes iteasy to install even very large moulds.PrecisionThanks to the Z toggle, clamp movements areprecisely controlled even operating at peak speeds.Platen design was optimized by the finite elementmethod (FEM) to ensure optimal application offorce and minimal deformation for large and smallmoulds. Platen deflection is minimized. The resultDesign basics Page 7

CUSTOMER BENEFITSBuilt-in economic and process advantages –you just have to exploit themEX injection moulding machines have the capbilityto deliver a high return on your investment, longtermproductivity and environmental compatibility.Outstanding performanceVery fast dry cycle times are a hallmark of EXmachines. The high speed and high performanceis the outcome of KraussMaffei’s dynamic clampconcept. The kinematics of the patented Z-toggleresult in a clamp speed profile that is close tooptimal, highly dynamic responses and the fastestdry cycle times in the industry. The all-electricmachine is engineered for parallel movementsthat cut cycle times. The result is faster cycles andhigher productivity.As clean as they comeEX machines are capable of meeting even the mostexacting cleanroom specs. The efficient watercooling system contributes to the uniform laminarflow of air through the clamp, by ensuring that lessheat is given off to the environment and that heatdissipation is uniform. This reduces the load on themanufacturing cell’s air conditioning system. Theuncontaminated mould zone and the closed-systemlubrication also contribute to the excellentcleanliness record.EfficiencyEX machines achieve better efficiency ratings thancomparable hydraulic machines thanks to electricdrives with direct transmission of drive energyto machine movements. These high-performancemotors also convert braking energy into electricityto reduce power consumption and heat generation.Cooling water is used twice over – to cool theconverters and the drives. Besides cutting waterconsumption significantly compared with conventionalmachines, the system dissipates heat moreefficiently. The result is an outstanding energybalance with savings potential of up to 50% andlower unit manufacturing costs.Premium precision32-bit signal processing for high-resolution controlof all movements guarantees highly repeatableprocesses within tight tolerances. The movementsof the electrically driven clamp can be preciselycontrolled for very high product quality. Extremelyconsistent shot weights, with variation under0.07% guarantee premium products and enableclose control of material consumption.
