Customization Options for Cast Urethane Products
What if you need a urethane product tailored to your specific needs? Well, that’s where customization comes in. Custom cast urethane products can be designed in an array of shapes and sizes, from items under a gram to those over 2500 pounds. Whether you need sheeting, rings, gaskets, rollers, or bushings, you can customize your urethane products in terms of shape, size, durometer, and even color.
Custom formulation options are also available, allowing additives to be introduced into the cast urethane products to improve characteristics such as reducing friction, enhancing UV resistance, and increasing flame retardation.
Size Customization
Size matters, especially when it comes to manufacturing parts. Cast urethane products can be made in a diverse array of sizes, from tiny components to large items weighing over half a ton, offering extensive size customization. For small cast urethane parts, a minimum wall thickness of 0.020 inches is recommended, and for larger parts, a minimum of 0.040 inches is typically necessary.
The vacuum casting process allows for the production of approximately 50 casts from a single silicone mold, providing a cost-effective and swift solution for creating larger cast urethane parts.
Durometer Variations
In the world of molded urethane products, hardness matters as much as size. Durometer variations in cast urethane products enable their use in a wide range of applications due to their different hardness levels. Urethane materials are available in various hardness specifications, categorized by Shore durometer scales, where ‘A’ denotes softer materials and ‘D’ signifies highly rigid ones. By adjusting formulations, the physical properties and hardness of custom-molded urethane products can be specifically tailored to meet diverse application requirements.
