Composite Tooling

Putty, Block Foam, Wood, Composites, Metals


Proprietary Putty Patterns

  • 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 the 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 are 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 Janicki’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.

Gel Coat Tooling

Janicki’s Gel Coat tooling is designed with hard, durable, high-gloss surfaces required to produce superior-grade products for marine, transportation and architectural industries. Our Gel Coat molds have a mirror-like finish, that is scratch and craze resistant for producing products with a high-quality finish.
Janicki Gel Coat molds are made of fiber-reinforced composites with low-shrink performance polyester resins using infusion or open-molded processing in a typical thickness of 0.625 inches.

  • Fiberglass Facesheet
  • 200°F Temp Tooling
  • 200+ Part Cycles
  • Trussed Steel Frame
  • 400 Grit and higher finish
  • Resistance to ultraviolet degradation and hydrolysis
  • Produce aesthetically appealing parts
  • Long-lasting maintenance-free performance
  • Protective barrier that increases the life and cycles of the mold

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

Cast 250° Tool

  • 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.

Cast 350° Tool

  • Use Temperature: 350° F
  • Tolerances: up to ± .010″
  • Support: Composite egg-crate

 Machined 350° Tool

Machined 350° tools are infused on a pattern and machined on its support structure with our 5-axis mills.

Machined 350° Tool

  • Surface is extremely accurate and finished to exact specifications
  • Use Temperature: 350° F
  • Tolerances: ± .005″ – .015″
  • Finish: Machined; 32 rms typical
  • Support: Steel or Composite egg-crate
