Are you looking for cast urethane products for your specific industry? Urethane, or polyurethane, is a versatile material that is useful in many industries. Urethane can be customized in almost any shape and size to fit your unique needs. You can use custom-molded urethane repeatedly in adverse environments without significant wear or damage.

Moreover, custom-molded urethane parts are a great way to get the look you want without using a more expensive or difficult-to-work-with material. You can choose from various colors, patterns, and textures, so you can find something that suits your preference exactly.

However, finding the best-cast polyurethane products can be challenging. There are countless options, and choosing the wrong product can impact your business. That’s why we’ve put together this guide to help you find the perfect urethane for your needs. We’ll show you how custom molding is done and how to ensure you get the most value out of your purchase.

How Can You Customize Urethane?

For most industries, customizing urethane parts is an excellent way to increase efficiency and bring products to the market quickly. In addition, it’s the ideal solution when durability, weight, and safety are highly regulated.

Usually, producing custom-molded urethane varies depending on your preferences and applications. To give you an overview, we discuss the process below.

Mold Creation or Tooling

Before we start the production process, we’ll create custom molds that match your exact shape and performance requirements. Here, a machinist will create a tool path based on your specific requirements. The tool path will produce a mold for the part that, when filled with urethane, will yield an extremely precise product. Urethane custom molds are often intricate as parts become more complex.

Mass Production

When the molds are ready, they enter the production room for custom molding and mass production. Here, the production team uses different prepolymers, curatives, and ratios to create formulations that are specific to the particular job. These specially formulated mixtures (or urethane resin) are generally hand-batched or processed in automated dispensers or centrifugal mixers, depending on the specifications of the parts.

In the production room, our team uses several forming and curing methods to meet the end-use needs of customers. Here are some techniques used in the industry.

Compression Molding

Using compression molding, liquid polyurethane or millable gum is placed into enclosed multiple plates. Then, two hardened steel plates sandwich the compound using a hydraulic press. The press exerts high pressure and heat, forcing the polyurethane to fill the shape of the closed mold for curing.

This method is usually more expensive than other molding processes, but it allows for a much higher-quality end product. With a more refined outcome, this process is ideal for casting polyurethane bushings, seals, and other critical parts. However, it can be more expensive than other methods.

Open-cast Molding

Open-mold products are formed by pouring liquid polyurethane into an open mold. After pouring, the process is followed by curing the mold in an oven or heated table. This process is a fairly affordable method that produces high-quality parts.

Centrifugal Molding

Also called spin casting, centrifugal molding is a process that creates lightweight yet strong custom urethane in a single shot. As the liquid polyurethane is spun inside the mold, a centrifugal force channels liquid to fill every part of the mold, creating one solid piece. The finished product is well-suited for smaller parts that need to be bubble-free.


In this process, the liquid urethane is pushed into a mold at high pressure using a molding press. The resin conforms to the mold and hardens, shaping the material into almost any desired shape. Ideal for making bulk pieces, this method is cost-efficient and reliable while still allowing for customization.

Trimming/Secondary Machining

Trimming is a crucial step in the production of custom polyurethane products. In this step, our team removes excess urethane and creates clean, finished products. In some instances, some parts may undergo secondary machining, depending on their end-use. The parts are returned to the machine shop, where they may be milled or ground.


Inspection is the final step before shipment to customers. In this step, end products are inspected for precision and quality. If a part fails our standards, we discard it and manufacture a new one.
