JI Proprietary Putty Patterns

tooling.pattern

  • Strong wooden substructure, foam, fiberglass and in-house engineered putty
  • Machined to specific tolerances
  • Extremely accurate and very fast turn-around at an economical cost
  • Easy-to-sand surface can be finished to 80 grit or given a machined primer surface and sanded to a finer finish.
  • Male or female shapes are available depending on application and geometry provided.
  • Designed for room temperature applications, but can be modified to withstand temperatures up to 180ºF
  • Primer surface option available
  • Laser tracking and vacuum integrity options available

Block Foam Patterns & Wood Patterns

  • Machined pattern fabricated out of block foam, MDF or modeling board.
  • Block foam allows for the maintenance of higher tolerances and can reach higher curing temperatures than the JI proprietary putty patterns
  • Medium Density Fiberboard (MDF) wood is stable at higher temperatures than putty, however the surface finish may be rougher.
  • MDF is also a suitable material for casting patterns.
  • Foam patterns can also be provided with a primer finish.
  • A wide variety of foam materials and densities are available depending on your application.

Short Run Molds

Using JI’s putty material system, we make short run molds for one-off or short-production production runs. By shipping in segments and assembling onto a steel frame, there is virtually no limit to the size of the part.

Cold Molded Tooling

  • Cold Molded Tools start with a rigid steel reinforced space frame as the base.
  • Wooden station frames are attached to the frame to form the basic shape.
  • Wooden battens are planked between the wooden station frames.
  • Thin sheets of plywood are molded over the wooden battens to create a wooden face-sheet.
  • A Fiber Reinforced Plastic (FRP) vacuum barrier layer is then applied to the wooden face-sheet.
  • JI proprietary putty medium is sprayed onto the FRP layer before machining surface to the final net contour.
  • Surface finished to the customer specified requirement.
  • Verified for both vacuum integrity and surface contour conformity.
  • Can be built in multiple sections and installed at the customer’s facility allowing you an unlimited range of sizes for your tooling application.
  • Very accurate and stable; can be used for multiple mold prints with minimal maintenance and repair between cycles.

Fiber Reinforced Plastic Tools

Molded from machined patterns; built to customer specifications. Composite consists of varying thickness fiberglass layers, a rigid balsa or foam core, and a durable tooling gel-coat finish. We have engineered FRP mold systems up to 220 feet in length.

250° Composite Tools

Carbon fiber or fiberglass composite tools, surface finishes optional depending on customer needs.

Cast 250° Tool

Also referred to as molded or transfer tools

tooling.cast250

  • Infused on a highly accurate machined pattern
  • Use Temperature: 250° F
  • Tolerances: up to ± .010″
  • Support: Steel tubing or composite egg-crate

Machined 250° Tool

Machined 250° Tool

  • Machined tools provide higher accuracies than cast
  • Includes laser tracking reports and vacuum verification
  • Use Temperature: 250° F (modifications can provide a 300° use temperature)
  • Tolerances: ± .005″ – .015″
  • Support: Steel or composite egg-crate

350° Composite Tools

Our 350° tools are a carbon fiber or fiberglass tool infused with an epoxy resin formulated to customer specifications. These 350° tools are available in two variations: cast and machined. Machined tools allow for the maintenance of higher accuracies. These 350° tools are provided with laser tracking and vacuum verification is performed to ensure conformity.

Cast 350° Tool

Cast 350° tools are infused on a highly accurate machined pattern and produce an accurate tool with optional surface finishes.
