Spray Moulding - El proceso de fabricación de los componentes de múltiples capas

Conformado con RAKU-PUR. El spray moulding se utiliza para reforzar de componentes dibujados profundos. Nuestros materiales del poliuretano (PUR) demuestran fuerza de alto impacto y ayunan curando. El spray moulding que cubre también ofrece muchas ventajas para la producción de componentes plásticos ligeros y rugosos. Demuestra la producción material baja de la consumición, fácil y rápida de geometries completos así como basura del punto bajo. RAMPF Giessharze ofrece más lejos versiones alimento-genuinas.

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: The backfilling with rigid foam

  • The material can be foamed into the closed mould using a high pressure
    mixing-head
  • This ensures high mechanical stability, good heat insulation and an ideal,
    light-weight construction
  • The rigid foam has an excellent adhesion to the previous layers

5. Demoulding or deflashing the component

Our special service: The Spray-Mobil

  • With our mobile spray equipment, we come straight to your company
  • Consequently, there is no interruption to your daily production routine
  • You are able to test our innovative material in your own forms

Efficient and highly flexible process for the production of complex large components

Example of uses:

  • Bonnet and other complex equipment for instance the shaft inliners, strengthening of deep drawn components such as bath tubs, light-weight components in a sandwich structure for refrigerated trucks or caravans
