Close Contour Pastes (CP)

RAKU® TOOL Close Contour Pastes are two-component epoxy systems that are processed and applied using a mixing and dispensing machine.

They are applied to a close contour substructure by hand or using a CNC machine. Almost any kind of supporting structure can be used, including RAKU® TOOL SB-0080 styling board, EPS, and cast aluminum.

The thixotropic systems enable quick and easy processing, with no slump on vertical surfaces. Milling based on CAD data takes place after a brief curing process at room temperature.

Close contour application significantly reduces the amount of material, milling, and finishing required and also the quantity of production waste generated.

All industry-standard paints can be used.

RAKU® TOOL repair systems with original epoxy paste resin are available.

RAMPF Tooling Solutions offers its customers a paste application service and the comprehensive technical support of experienced engineers.

If you choose RAKU® TOOL Close Contour Pastes, you are choosing homogeneous, seamless surfaces, optimum dimensional stability, and extremely cost-effective model & mold manufacturing.

Applications include design and styling models, molds, large-scale modeling, and rotor blade, wind turbine, and boat models.

Repair Systems for Close Contour Pastes

RAKU® TOOL two-component epoxy repair systems are specifically designed to match the relevant Close Contour Pastes.

The components are easy to mix according to the specified mix ratio and are applied using a spatula.

A temperature of between 20 and 25°C is recommended for processing.

The repair systems can be applied to vertical surfaces in layers up to 20 mm thickness without any slump.

RAKU® TOOL repair systems exhibit similar mechanical properties to the cured Close Contour Pastes. The pot life is sufficient with rapid curing.

Epoxy Pastes (hand-applied) (EP)

RAKU® TOOL hand-applied pastes are two-component epoxy systems that enable easy manual application and processing.

The range comprises an apricot-colored styling paste with a density of approx. 0.53 g/cm3 and a brown modeling paste with a density of approx. 0.7 g/cm3.

RAKU® TOOL hand-applied pastes are very easy to handle with woodworking tools and adhere extremely well to most substructures.

Applications include design, styling, and master models as well as molds.

Close Contour Casting (CC)

RAKU® TOOL Close Contour Castings are semi-finished polyurethane products supplied as three-dimensional castings that are already close to the final contour.

The manufacturing process takes place in-house at RAMPF Tooling Solutions. The cavity is milled into a lightweight mold material such as EPS or RAKU® TOOL SB-0080 styling board based on the data provided by the customer. Following application of the release agent, the cavity is filled using a special casting process.

Once the casting has cured, been removed from the mold, and undergone post-curing, milling is quick and easy.

Close Contour Blocks (CB)

RAKU® TOOL Close Contour Blocks are special blocks made of polyurethane or epoxy. They are produced to customer specifications (L x W x H) in the usual high board material quality and supplied as customized, unmachined rectangular blocks complete with order management.

With their very fine, seamless surfaces, Close Contour Castings and Close Contour Blocks are sure to impress. The close contour form significantly reduces the amount of material, milling, and finishing required and also reduces waste.

Applications include styling, master, and data control models, seamless galvano bath models, lay-up tools for standard and low-temperature prepregs, RIM tools, metal forming, checking fixtures, vacuum forming molds, pattern plates, core boxes, milled negatives and positives, and hammer forms.
