Polyurethane Tooling Board

Alro Plastics is now a stocking distributor of Polyurethane Tooling Board. In order to better service our customers, we have broken them down into three categories. Light, Medium, and High density Tooling Boards. Please click on one of the photos to find out more about each of the products listed.

Light Density, Modeling / Styling Board
Go to Light Density Page	Generally speaking the Light density boards fall between the 4 lb and 30 lb density range. Often referred to as Polyurethane Foam board, it is ideal for making patterns and models.
Medium Density, Tooling / Fixture Board
Go to ProLab 65 Page	Go to Lab 1151 Page
Go to Lab 1147 Page	Medium density polyurethane tooling board is a machinable slab designed for production of patterns, mock-ups, prototypes, master models, fixtures, jigs and other rapids tooling applications.
High Density, Tooling / Pattern Board
Go to Lab 850 Page	Go to Lab 1000 Page
High density boards are often used for metal forming, stamping and stretch press dies. A proven material for medium-volume foundry patterns, core boxes, gating and risers.

Common Advantages Compared to the Alternatives&

• Ease of Machining - Because boards are consistent, uniform and grain-free, concerns with cutting-direction, tear-out and warping are few. Faster CNC-machine spindle speeds and material feed rates are possible, increasing productivity. These materials are non abrasive which will minimize tooling wear and need to resharpen.
• Light Weight - Approximately one-half the weight of wood.
• Shop Safety - Most board products create shavings when cut, and many contain anti-static additives for reduced shop dust on the floor and in the air. They are also non toxic.
• Dimensional Stability Boards are closed-cell, and predominantly polyurethane-based, making them relatively insensitive to humidity changes.
• Temperature Resistance - Most boards are useful up to 150 degrees F, with many usable at temperatures of 210-225 degrees F. Some up to 300 degrees F.
• Easily Bonded and Repaired - Many manufacturers offer specific adhesives and patch compounds for tooling boards, matched to particular grades.
• Easy Surface Finishing - Almost all of these products accept a wide-range of coatings and finishes. Small cell-sizes give very good (to excellent) finished surface results. It is possible (with special equipment and process) to create polished-metal surfaces on prototypes made with tooling boards and foams.
• Larger Block Sizes Available Some manufacturers offer up to 20 thick boards, and up to 5 X 10 in width and length, greatly reducing glue-up labor in build-ups. Many of these shops labor rates exceed $50.00 per hour so these larger sizes are a tremendous advantage.
