Advantages.

Legacy Foam is cutting edge, innovation leading foam pattern technology. When compared to traditional wax patterns, the advantages are unparalleled!

Computer Controlled Process

With our equipment, mix ratio, mixing speed, injection speed, shot size and individual job parameters can all be individually adjusted and stored for pattern-to-pattern consistency. Programs can be copied from machine to machine and backed up by your network backup system.

Dimensional Accuracy

Long shelf life, no warping, robust, not affected by humidity, and setting fixtures are not required.

Thin Sections

Patterns stay straighter and flatter.

Excellent Surface Finish

​

Lighter Weight

At 15lbs/cu.ft. Foam Patterns are approximately 60% lighter than wax patterns.

Cost Less

Pattern wax can cost more than $5/lb. While liquid foam also costs about $5/lb., it expands more than 5:1, so foam patterns can be 50% the cost of wax patterns or less!
​

Less Scrap

Cured foam is resilient and does not break with moderate flexing. This allows for less breakage during demolding.

No Chills

​Pattern foam can be cast in sections up to 4 in. / 100 mm thick with no appreciable deformation.

Dimensions are not affected by Heat or Moisture in a normal foundry environment

​In typical pattern storage conditions, foam patterns may be stored for many months without dimensional change, sagging, or distortion. Temperature/humidity controlled pattern production/storage rooms are not required.

Ceramic Shell Cracking Virtually Eliminated

​

Less Costly Injection Equipment

A wax injection press can cost $200,000 or more. Our equipment and accessories cost less than that.

Robust Tree Assembly

With our proprietary assembly and patching paste products, damaged areas can be repaired, material can be added as desired, and assembly time can be reduced. ​

Gating Advantages

Foam Patterns become more and more cost effective as cross sections increase. Also, incorporating gating molds into your tooling program reduces cost and time for repetitive production orders. Innovative tree designs and self-registering gating joints can improve tree consistency and strength.

Efficient Tooling

Molds can be designed for common runner and riser shapes and used on multiple projects.

​Training Class

​When you buy our proprietary pattern foam you become eligible to enroll in our training class. We will show you how to set up your equipment and teach you mold design considerations. You will participate in hands-on training for preparing molds, shooting parts, processing patterns, repair and tree assembly.
