Prototyping & Tooling

Epoxy, urethane, and SLA resins—modeling, working, and HDU tooling boards—for your applications

Whether you’re an engineer, mechanical designer, model maker, or tool or prototype developer we can help you select the materials you need for your application challenges. To help bring your initial designs and concepts to life, we have a full range of prototyping and tooling materials to support your product and part development. Our extensive product line includes:

Trends in Prototyping

The prototyping stage has become more and more critical in recent years as the pace of new product development has accelerated and product lifecycles have contracted. Since most product design work is now done with some type of computer software, the first model of a new product is often a series of computer files. Converting these files into three-dimensional physical models can be accomplished through an additive or subtractive process.

Three Dimensional Physical Models

Additive Technologies

There are several additive technologies but they all share one thing in common—the computer models are cut into layers and this data is used to construct 3D models in a layer-by-layer fashion. One of the most accurate and popular additive technologies is stereolithography (SLA). SLA begins with a liquid photopolymer. The layer-by-layer building process is carried out with a UV laser. As the laser traces out each layer, all liquid polymer struck by the laser instantly solidifies.

Subtractive Approach

The subtractive approach begins with a large block or buck of machinable material. A CNC milling center, working from the computer model, cuts away at this material until the 3D model remains. Urethane tooling board is widely used for this purpose. Individual boards are laminated together with appropriate adhesive to create the buck. Urethane tooling boards come in a variety of densities. Higher density boards offer better strength and durability while lower density boards offer lower cost. Urethane tooling board is cheaper than aluminum and more dimensionally stable than wood products such as MDF, pine or mahogany. Once a one-off prototype has been made with either approach, replicas of this prototype can be made quickly and inexpensively using silicone moldmaking materials and liquid urethane or epoxy casting resins.

CNC-Machined Molds and Plugs for the Composites Industry

Urethane tooling boards are also increasingly finding use in CNC-machined molds and plugs in the rapidly growing composites industry. CNC equipment permits the production of highly accurate molds. Molds made from urethane tooling boards remain dimensionally accurate in storage for years because they do not shrink with time and are unaffected by moisture. In recent years, the trend has been toward lower density foam in order to improve economics. Densities ranging from 20 PCF to 2 PCF are popular. Reducing density even slightly (for example from 10 PCF to 8 PCF) can provide significant cost savings. There has also been a shift from polyurethane foam to polyisocyanurate foam. Polyisocyanurate foam (also called ISO foam), is noticeably less expensive than polyurethane foam, at the same density. Another interesting trend is the use of machinable epoxy-based tooling pastes. Tooling pastes allow use of very low density foam for the interior volume of a plug or mold. The foam core is covered with the tooling paste. After curing, an epoxy shell is CNC machined to yield a very fully-dense, very durable, high-temperature tooling surface which will hold vacuum and stand up to numerous pulls.

Epoxy surface coats (room temp, high temp)– are paste-viscosity resins designed to be applied by brush or squeegee to a model or pattern to function as the surface of the cured tool. They generally possess handling properties that facilitate easy mixing and application, and their cured properties provide a tough, durable surface that can be sanded or scribed with ease.

Epoxy laminating resin systems (room temp, high temp)– consist of both unfilled and filled products that are intended for use with reinforcing fabrics to construct high performance composite tooling prototypes and/or production parts.

Epoxy casting resins (room temp, high temp)– are versatile products that can provide an excellent solution to a variety of industrial applications. They generally contain a filler of some type that is provided to produce specific handling or cured properties. These fillers can be of a metallic or non-metallic nature. Certain fillers can provide lower shrinkage, higher compressive strengths, better metal forming properties, or other characteristics suited to a particular use. A variety of systems, for both room temperature as well as high temperature service are available with different hardeners to more closely match the material to the application.

Vacuum-assist resin-transfer method (VARTM)– is the procedure of infusing a resin matrix into plies of dry fabric, under vacuum, to make composite laminates. In this process, dry plies of fabric are laminated onto a hard mold surface along with release plies, flow media, vacuum lines, and resin distribution lines, with the entire laminate placed under a vacuum bag. Infusion resin/hardeners are batch-mixed and sucked into the laminate, by vacuum, through resin distribution lines. VARTM-type resin systems are identified by very low mixed viscosities and longer working times. Resin infusion for tooling has a number of advantages over using prepreg tooling materials: much lower material costs, easier ply positioning, less chance of delamination, no autoclave required, room-temperature demold, free-standing post cure, no refrigerated storage, and long shelf life. Resin infusion for production parts offers the same advantages as for tooling. This process is usually reserved for large structures such as boats or composite car bodies.

Epoxy casting and epoxy laminating resins are widely used for:

  • High-performance composites based on glass, carbon, Kevlar®, and other fiber reinforcements
  • Lamination
  • Surface coat
  • Casting

Performance characteristics:

  • Tough
  • Rigid
  • High temperature resistance

Urethane Casting Resins

PTM&W urethane casting products are two-part systems designed for tooling and production and prototyping applications. Durometers range from 40 Shore A to 85 Shore D.

Urethanes for tooling are grouped into 5 categories divided by hardness and related end uses.

Soft urethane elastomers for tough, flexible tooling and molds are generally 50 Shore A Hardness and under, and are ideally suited for applications such as bumpers, pads, and flexible molds or soft parts where a high degree of flexibility & toughness is required. Their relatively high tensile strengths make them good performers for masking or holding fixtures where the tooling needs to be
stretched to apply and remove.

Mid-range hardness urethanes for high strength tooling and molds are tough elastomeric urethanes that are generally in the 60 - 80 Shore A hardness range. They perform very well in light metal forming dies such as brake form pads. Their slightly tougher nature, compared to softer materials, makes them ideal for applications such as very tough high strength flexible molds, and they produce durable, abrasion resistant shapes and parts, cutting pads, fixtures, and flexible parts.

Hard elastomeric urethane tooling materials range in hardness from Shore A 90 to Shore D 60, and are work horse metal forming materials. They are also used extensively in the foundry, where they are capable of outlasting metal patterns in many applications. Shore A 90 and Shore A 95 urethane systems are harder flexible elastomers with very tough cured properties that make excellent metal forming tooling and are useful in many other demanding industrial applications. Forming dies, die springs, stripper pads, patterns, gears, and tough parts are all applications in which these hard elastomers excel. Shore D 60 urethane systems are exceptionally tough, hard elastomers, that have cured characteristics which make them well suited for some very demanding industrial uses.

Rigid urethane elastomers are very hard systems (75 Shore D and harder), are plastic-like in appearance, yet provide the inherent toughness and durability of engineering elastomers. They work very well in tooling applications such as patterns, molds, and fixtures. They are ideal for the fabrication of high strength rigid parts such as seals, bushings, and prototype items.

REPLICAST fast setting tooling urethanes are a line of products consisting of hard, rigid, fast setting general purpose urethane systems for the rapid production of temporary and short-run tooling, various jigs and fixtures, as well as rigid, durable shapes and parts.

PT8442 has a low very fluid mix viscosity, providing easy mixing and pouring, and efficient mold filling, even in thin wall sections.

Tech Tip– Generally, with polyurethane elastomers, full properties are developed in 7 days at room temperature (75°F). Temperatures below 75°F will lengthen the cure time, and if the ambient temperature is below 60°F, additional heat may be necessary for proper cure. Elevated temperatures will accelerate the cure of urethanes, but care must be taken if a higher temperature is used to cure the material. Generally, the higher the curing temperature, the greater the final cured shrinkage. When heat curing for more rapid processing, to best control shrinkage, the casting should be allowed to set for 12 to 18 hours at room temperature before an oven post cure. A typical accelerated curing cycle, therefore, would be: Allow to gel on the pattern for 12 to 18 hours at room temperature (70°F to 80°F), then post cure for a minimum of 8 hours at 150°F to 165°F and allow to cool before demolding.
