The Benefits of Custom-Molded Parts

Custom-molded parts by Monroe Engineering

When shopping for seals, gaskets, hoses, tubing and other machine parts, you can’t ignore the benefits of custom molding. Custom-molded parts are manufactured using a molding process. Injection molding, for instance, is often used to make custom-molded parts. With injection molding, heated material is injected into a mold cavity. As it cools, the material will harden to create a new part. Why should you choose custom-molded parts exactly?


Custom-molded parts are strong. They can withstand harsh temperatures, as well as extreme environments, without damaging or otherwise degrading. After all, most custom-molded parts are made of material that’s preheated before being injected into a mold cavity. When the material cools, it becomes stronger. You can find custom-molded parts in different materials, but they are all exceptionally strong.

Resistant to Corrosion

Corrosion typically isn’t a concern with custom-molded parts. They generally don’t contain any materials that are susceptible to corrosion. As a result, custom-molded parts can last a long time — even when used in humid or wet environments. The corrosion-resistant properties of custom-molded parts makes them a popular choice for machines.


Custom-molded parts are elastic. Most of them are made of materials like rubber, plastic or thermosetting polymer. All of these materials are elastic. In other words, they can deform when exposed to pressure, and they can revert back to their original shape when the pressure is released. With their elastic properties, custom-molded parts are ideal for sealing applications. Custom-molded gaskets, O-rings and other seals can prevent leaks in the machines with which they are used.

Supports a Variety of Shapes and Sizes

You can order custom-molded parts in a variety of shapes and sizes. The shape and size of a custom-molded part, of course, is dependent upon the mold. To create a part in a specific shape and size, manufacturing companies use a corresponding mold in the same shape and size. As long as the mold cavity features the same size and shape, all casting made with that mold will have a uniform design consisting of that size and shape.


Another benefit of custom-molded parts is the price. There are other ways to produce parts. When compared to custom molding, though, they often require more time, labor and energy. Manufacturing companies can produce parts more quickly and efficiently with custom molding. Therefore, they pass these savings down to to their customers in the form of lower prices. You can save money by choosing custom-molded parts for your business’s needs.
