Advantages of Urethane Castings vs. Injection Molding

Urethane castings provide a cost-effective alternative to injection molding. Urethane castings are used to produce rigid and flexible plastic parts similar in quality to injection molding parts. While not suitable for use in large production runs like injection molding, urethane castings are ideally suited for prototyping and small and medium production runs.

What Are Some of the Advantages of Urethane Castings?

In addition to the lower tooling costs, urethane castings can provide many advantages over injection molding. Urethane castings have an extremely fast turnaround compared to injection molding and other processes. There are many production materials to choose from, ranging from rigid and impact resistant to soft and flexible materials. A wide range of colors, textures, and finishes, including high-polished, grained, brushed, leather grain, and textiles are available.

Urethane castings can achieve geometries impossible for injection-molded parts. In a lot of instances, urethane cast parts are indistinguishable from injection molded parts with similar strength and durability properties.

Urethane castings are used in a number of applications, including:

  • Rapid Prototyping
  • Low To Medium Production Runs
  • Pre-Production Runs
  • Lower-Volume Manufacturing
  • Consumer Products
  • Concept Models
  • Sales Samples
  • Scale Models
  • Automotive Parts
  • Medical Devices
  • Consumer Testing
  • Aircraft Interior Components
  • Marketing Test Samples
  • Test Prototyping

The Urethane Casting Process

The urethane casting process is similar to the injection molding process. A 3D printer is used to produce a master part/pattern based on a digital design. Once this master part/pattern has been inspected and finished it will be placed in liquid silicone to create the mold. After the silicone has been allowed to cure, the mold is halved and the master part/pattern is removed. The void created by the master part/pattern is used for the casting of extremely accurate and detailed duplicates of the master pattern.

5 Benefits of Cast Urethane Parts

Efficient Turnaround Time

Time is of the essence in the manufacturing world, and we understand that any downtime during your production process costs you money. When you need prototype parts for testing purposes, the last thing you want is to wait any longer than necessary to receive them. Urethane parts can be cast very quickly and easily, and this efficient turnaround time allows you to enjoy a much more efficient production process, from design inception and engineering to testing and mass production.

Accurate Production

If your company relies on prototype parts for alpha and beta testing of your new products, then you deserve to have confidence in the integrity of the parts you use in the testing process. There are many different types of materials that can be used to manufacture the parts needed for your testing procedures, but none of them offer the accuracy of cast urethane parts. This is because urethane has a very minimal shrinkage rate, which ensures that your part can be produced with incredible accuracy. This accuracy during testing results in a tried-and-true end product that will perform and last as you (and your customers) expect.

Custom Colors and Finishes

In addition to lending itself to efficient and accurate production needs, urethane also provides you with many different types of colors and finishes to customize your finished product as you so desire. If your product relies on multi-durometer parts to perform properly, then urethane is an ideal material to make them out of. Not only do these parts offer varying degrees of hardness, they also come in a wide variety of colors, from simple neutral tones to bold, vibrant shades that are sure to complement any type of product.

Affordable Prototype Parts

Before you unveil a new product, you need to know that it works exactly as you designed it to. This often requires extensive testing, and the type of prototype parts you use for the testing process can have a big impact on the results you receive. Therefore, high-quality parts are essential to the testing process, but that doesn&#;t mean that they have to be expensive. Cast urethane parts offer an affordable alternative to other materials, and they offer incredible durability that stands up to rigorous testing procedures.

Durability for Maximum Wear and Strength

Whether you are in the process of completing alpha and beta testing of your product, or you are ready to distribute your finished goods worldwide, you need to know that you have developed a product that meets the demanding quality expectations of your company. Likewise, you deserve to have a product that proves itself time and time again when put to the test in the real world. Urethane parts offer uncomparable durability when compared to other materials, and this will provide you with a strong sense of confidence in your product. You won&#;t have to worry about the part failing during testing procedures or falling apart in your customers&#; hands.
