浪花涂层 - The manufacturing process for multi-layer components

Designing with RAKU-PUR. Spray moulding is used for reinforcing of deep drawn components. Our polyurethane (PUR) materials show high impact strength and fast curing. Spray moulding also offers many advantages for the production of lightweight and rugged plastic components. It shows low material consumption, easy and fast production of complete geometries as well as low waste. Further more RAMPF Giessharze offers food-genuine versions.

1. Construction of an open mould

2. The first spraying: Creation of the compact outer skin

  • The application of the material can be done using either a high or low
    pressure process
  • The material is ideally sprayed using a robot technology
  • The sprayed skin has an optically beautiful, very smooth surface
  • Easy to clean
  • Food safe
  • Light-stability is adjustable
  • The curing takes place in less than 1 minute
  • The layer thickness is between 1 – 2 mm

3. The second spraying: mechanical strengthening of the outer skin

  • The application of the strengthening layer can be done in a low or
    high pressure process
  • Simultaneous spraying of fibreglass or natural fibres is possible
  • The material also doesn’t drip when spraying on vertical surfaces
  • The high impact resistance of the material ensures the protection
    of the outer sprayed skin
  • The curing is finished in less than 1 minute
  • The layer thickness is between 5 – 15 mm

4. Optional: Die Hinterfüllung mit Hartschaum

  • Das Material wird mittels Hochdruckverfahren über einen Anguss in die dann geschlossene Form geschäumt
  • Dies sorgt für eine hohe mechanische Stabilität, eine gute Wärmeisolierung und eine ideale Leichtbauweise
  • Der Hartschaum haftet hervorragend auf den vorherigen Schichten

5. Demoulding or deflashing the component
