Injection molding is one kind of molding process that has uses in industries from toy making to automotive parts manufacturing. Injection molding is one of the oldest forms of molding. Injection molding is simply the process of injecting a material, such as urethane, into a mold, forming an object.
There are many advantages to using injection molded urethane, such as:
Abrasion resistance: Urethane dries hard, which makes it resistant to abrasives. This is ideal for high-use objects, including skateboard wheels, boats, car bumpers, and more.
High load bearing: One solid piece of urethane is stronger than an object made of several pieces. A molded urethane object can take a large amount of weight and pressure, ideal for uses in industrial and automotive industries.
Durability: Molded urethane is durable and long-lasting. The material will not break down with repeated use or even extended abuse, such as a boat would see in rocky water.
Resilient: Urethane provides just enough flexibility to maintain high resilience to chips, scrapes, bumps, and tears. Molded urethane can take abuse in many forms, and absorb pressure and damage that would break other, less resilient materials.
Mold and fungal resistance: Urethane is made from petroleum products and is immune to the growth of mold and fungus. Urethane lacks pores and other materials that attract the growth of mold. This makes it ideal for use in moisture-rich environments, such as the construction of vehicle seats, boats, or surfboards.
In fact, injection molded urethane is used in a variety of industries, such as the automotive industry to make instrument panels, seats, roof liners, dashboards, headrests, steering wheels, and even bumpers. The consumer industry uses molded urethane for tennis rackets, surfboards, skating wheels, boat hulls, and more. The unique properties of molded urethane make them ideal for use in every aspect of life.
