The die casting processes provide a great deal of flexibility for the production of metal components. Permanent mold and low-pressure die casting can produce parts from almost any metal in almost any shape.
The Features and Benefits of cast Polyurethane are superior to many other materials, in that it offers great abrasion and impact resistance, is available in a wide range of hardness, and can be static resistant. Because of it superior characteristics polyurethane can often replace metal, rubber or other plastics.
Urethane casting offers injection-molded quality parts in much shorter lead times than traditional tooling and molding. Stratasys Direct offers a wide selection of advanced formula polymers, shore A flexible and foam materials to suit most applications.
This liquid urethane casting system has excellent handling characteristics and will cure at room or elevated temperatures. CONATHANE® UC-40 is a liquid, two-component, unfilled urethane resin system that produces tough, high-impact resistant, dimensionally stable castings. UC-40 is used to produce prototype parts requiring a "thermoplastic" feel and appearance.
Urethane casting is a process of producing urethane materials to case components. Polymer molds made from a master pattern will also be taken advantage about this process. Additionally, this process is being used for the rapid prototyping of materials.
• Standard hardnesses are 60, 70 (72), 80 (82), 85, 90 and 95 Shore A Due to their good chemical resistance against lubri- cants, as well as their resistance to weathering and UV radiation, their high compressive strength, very high abrasion resistance and low deformation, castings and mouldings made from polyurethane are perfectly suited for seals or components in systems and machines.
Broad hardness ranging from 40 shore A to 90 shore A. Red, natural, and black are the standard and other colors are available upon request. Urethane is abrasion and cut resistant. Urethane is chemical and oil resistant. Urethane is machinable and resilient .Urethane has a lower tooling cost, has a high load bearing capacity and has elastic memory.
Quality Engineering Services provides precision cast urethane and RTV silicone molded products in quantities of one to one thousand. We offer a variety of material characteristics, colors and textures. Hardness can range from very flexable (Shore 10A Durometer) to very rigid (Shore 80D Durometer).
The best material for this is polyurethane foam. It comes in a two-part kit, similar to most RTV silicones and casting resins. It's slightly harder to work with than those other materials due to its very short pot life, but with a bit of practice you can achieve good results.
