high-precisionhigh-pressurehydraulic motor

PUR high-pressure mixing and dispensing unit for casting, injection or spray Technical data Mixing ratio stepless: 1:1 to 4:1 / 1:4 Viscosities: max. 5000 mPa·s Working pressure max.: 200 bar Shot size: 3 - ∞ g Floor space: 5 m2 Weight: ca. 2000 kg Electric power supply: 3 x 400 V / 50 Hz / 24 kVA Applications Production of technical parts in rigid foam, Duromers, flexible- or integral-foam as well as RIM systems in open and closed moulds. Very high repetition accuracy for minimum shot weights of 3 grams. Pressure tanks 39/100/250 liters, oilheated, incl. electric stirrer, level- and temperature detector, TÜV approved. Feeding hoses oilheated. Vacuum pump and automatic tankfilling device on request. Edge-filters With double-jacket for oilheating and electric motor for continuous cleaning are included in basic equipment. Dry-air flushing All ISO sealrings are continuously flushed with dry air (dewpoint -40°C). A typical ISOTHERM innovation to increase lifetime of seals. Dosing Four vertical piston pumps in tandem with hydraulic drive and fully automatic close-loop regulation of mixing ratio and output with digitally stepless adjustment. This oilheated dosing unit offers the possibility to realise small shots as well as continuous casting or spraying. Control Industrial PC (Windows XP Prof.) with touch-screen, shows clearly, safely and comfortably all relevant process parameters. Menu-aided parameter set and control, analysis of errors. Process parameters shown on screen. PC for easy and economic adaptions to customers needs in case of machine integration and software changes.
