Why a Promass Coating Line.

The module.

• Very stable and reliable X,Y,Z constructions.
  • Minimal maintenance by use of standard components and control systems.
  • Upto 7-axis servo and steppermotor driven.
    • X-axis, Y-axis.
    • Upto 3 pcs. Z-axis.
    • 1 pcs. Tilting.
    • 1 pcs. Rotation.

• Open construction.
  • Easy access to the nozzle’s.
  • All nozzle’s at the front (1-line).

Nozzle system.

• Independent Z-axis.
  • Upto 3 pcs. Independent Z-axis.

• Standard ‘off the shelve’ nozzle’s; wide range of nozzle’s available.
  • Needle,
  • Spray,
  • Micro spray,

• Short distance between Cartridge and nozzle.

• High accuracy of the nozzle
  • Auto calibration of the nozzle’s.
  • Standard 0.05 mm  repeatability of nozzle position.
  • Special applications: 0.02 mm. Repeatability of the nozzles.

The software.

• Easy to use Software.
  • Easy to learn.
  • Short time to program new products.
  • Easy to clean.

Movement of the gantry.

• High speed of the axis.
  • Short cycle times.
• We are using Hiwin guiding systems, combined with a tooth-belt drive system.
• For the XY movements, we are using servomotors in combination with the Omron controllers
• Our Z-axis (upto 3 pcs.) are driven by Hiwin guiding and spindle driven.
• Optional:
  • We can build a spindle driven movement of the gantry (X,Y).

Checking the viscosity and compensating it in automatic mode ?

• We can offer the option, to add an automatic scale to measure the amount of coating during 1 second of purging.
  • This weight is related to the viscosity and opening of the valves.
  • Based on these measurement, the speed of the spraying-needle valves can be corrected.

Checking and controlling the dimensions of the area to coat.

• The way of programming is, to load a picture of the product (can be done by the camera installed at the gantry or a  “product.jpg” can be loaded from the harddisk).
• With lines, circles, squares and so on, you can program the area to coat (like using paint).
• Every area will be connected with a needle or valve, incl. the parameters.
• Option:
  • After the coating process, it is possible to build in a control system (scanner system) to check the coated area.

• Checking based on reflection of the coating under an UV lamp.

Aperture of the spray.

• Option:
  • Installing an Omron laser sensor to check the width of the spray beam. The width of the spray beam is depending on:
    • Viscosity, depending on type of coating, temp. of the surrounding.
    • Opening of the nozzle,
    • Pressure on the coating pot,
    • Pressure on the shroud air,
    • Height of the nozzle above the product,
