Close Contour technology by RAMPF Group. Inc.

RAKU® TOOL Close Contour pastes and castings based on epoxy and polyurethane are used to manufacture high-quality models and molds that are already close to the shape of the final part. The benefits:

  • Minimal material usage
  • Minimal production waste
  • Extremely fast milling
  • First-class, seamless, and very fine surfaces without bonding lines

Close Contour Pastes

The two-component, thixotropic epoxy systems are applied to a close-contour shape supporting structure with a mixing and dispensing machine, cured, and then CNC machined according to customer CAD data; almost any kind of supporting structure can be used, including RAKU® TOOL SB-0080 styling board, EPS, and cast aluminum.

RAKU® TOOL Close Contour pastes exhibit outstanding dimensional stability and enable quick and easy processing with no slump on vertical surfaces and smooth overhead dispensing. Applications include design and styling models, molds, large-scale modeling, rotor blade, wind turbine, and boat models. RAMPF offers a paste application service and the comprehensive technical support of experienced engineers.

Close Contour Castings

The semi-finished polyurethane systems are supplied as a three-dimensional casting. The monolithic, close-contour block with even wall thickness is manufactured by RAMPF in Southern California and North Carolina based on customer CAD data.

The cavity is milled into a lightweight mold material such as EPS or RAKU® TOOL SB-0080 styling board. Following the application of the release agent, the cavity is filled using a special casting process. Milling is quick and easy. Applications include styling, design, master, cubing, and data control models.
