PSM90

Polyurethane high pressure unit. Compact PUR high-pressure unit for the economic, ecologic production of technical parts in small shot sizes.

PSM90

Technical data

  • Output stepless, close loop regulated: 0,6 - 5 l/min (10 - 85g/s)
  • Mixing ratio stepless, close loop regulated: 1:1 bis 4:1 / 1:4
  • Viscosity: max. 5000 mPa*s
  • Arbeitsdruck max.: 200 bar

  • Dimension (LxWxH): 2500 x 1200 x 2200 mm
  • Weight: 1540 kg
  • Electric supply: 3 x 400 V / 50 Hz / 24 kVA

Application

Production of technical parts in open and closed moulds. Shot weights of 3 to 1000 g

Pressure tanks

39 Liters stainless steel, doublejacket, oilheated, including electric stirrer, level- and temperature-senors, prepared for automatic tankfilling.

Filters

Edge-filters 0,1 mm, doublejacket, oilheated, including electric motor for cleaning.

Dry-air flushing

All Iso sealrings are continuously flushed with dry air (dewpoint -40°C). A typical ISOTHERM innovation to increase lifetime of seals.

Metering

Two oilheated vertical piston pumps with hydraulic drive and close loop regulation for mixing ratio and output, are responsable for the famous ISOTHERM metering precision.

Mixing head

Mechanically self-cleaning mixing heads with automatic recirculation of components, for smallest shot-size of 3 grams. Solvent-free, free of surge. For injection and spray.

Control

Industrial PC (Windows NT) with touch-screen shows clearly, safely and comfortably all relevant process parameters. Menu-aided parameter set and control, error-analysis. Process parameters sown on screen. PC for easy control adaptions to customers needs in case of machine integration and software changes.

Function

The components POLY and ISO, stocked and heated in pressure vessels, are metered by plungerpumps and transferred under high pressure to mixing head, resp. recirculate back to tanks. Optimal stability of temperature and pressure.

Options

Automatic tank filling units, external process data control, additional POLY circuits (for colour change), robotics, turntables aso.
