What is Polyurethane Molding?
Cast polyurethane, or urethane, (these terms mean the same thing) molding is typically a two component system of urethane and curative. The two components are heated, dynamically mixed together and cast into a heated mold. The two chemicals under heat crosslink and form a new stronger molecule now a thermoset compound.
This new thermoset compound is stronger than thermoplastics and rubbers because of the crosslinking. Once formed they can’t be melted back down, reground or used in any way in the production process again.
The continuous casting process can produce thousands of parts per day or a single mold can be filled to make one part only.
Urethane is a perfect material for molding since it can easily be adapted to any shape and form. It is also able to produce parts that are sturdy and rigid, or ones that are pliable and soft. These variations in the characteristics of polyurethane make it an ideal material for the production of strong, long lasting, and durable parts.
The polyurethane molding process is used for the production of high volumes of parts that can range into the tens of thousands. When large quantities are required and time is important, polyurethane molding is an excellent choice since it has the ability to produce thousands of parts per day with every part having exactly the same quality and tolerances.
Benefits of Polyurethane
Due to the fact that polyurethane is lightweight, has low production cost, and has exceptional physical properties, the polyurethane is adaptable to a variety of industrial uses. The urethane parts have noise abatement, chemical resistance, abrasion resistance, excellent cut and tear properties. Some of the many parts made with cast urethane are: gears, sprockets, bumpers, rollers, automotive mounts, seals and many more items.
One of the outstanding benefits of urethane is its ability to be custom designed to provide solutions for unique, unusual, and specialized manufacturing conditions. Parts can be produced that weigh a few grams or up to thousands of pounds. The only requirement is the submission and creation of the design to be produced.
