Advantages of Urethane Reaction Injection Molding Over Natural Materials

The productivity of the material will be improved with urethane's abrasion resistance, its ability to withstand rubbing, scraping or erosion. This positive trait helps maintain the product's original appearance and structure. Overall, its resilience and easily moldable properties can make urethane an excellent material for RIM.

Urethane has Superior Qualities to Rubber

Some of the same advantages of urethane over metals, such as excellent abrasion resistance and the many different molding capacities are the same with natural rubber. Added benefits are the high cut and tear resistance, a broader hardness range and low pressure tooling. Urethane offers oil resistance, ozone resistance and radiation resistance - making a sturdy RIM product. It can be processed into very thin items and have much thicker sections without a curing gradient.

And lastly, but not least, is the superior load bearing capacity, which is basically the properties of the urethane reaction injection molding developed part to maintain its reliability without failure.

Overall, urethane is a tough material. Not only does it have the advantages over metal and rubber, it features high tensile strength, the maximum force a material can withstand without tearing, as well as excellent elongation and dimensional stability. One the one hand, it is flexible at extremely low temperatures, yet on the other hand it has high heat resistance. It is quite resistant to environmental factors as well as bacteria, acids, chemicals and solvents. As you can see, the advantages of using urethane reaction injection molding outweigh the use of natural materials.

Whatever the item a person or a company intends to produce, creating a prototype is a crucial step in the design process that cannot be glossed over. Why is prototyping important? There are several main reasons; testing and evaluating the design, clarifying production issues and costs, selling it to others, as well as making clear any patentable details.

Evaluating and Testing the Design

Unfortunately, ideas and drawings of a design can sometimes be a far cry from the real world in which the product will be used. By creating a prototype it is possible to sit down with a real version of the product and determine which aspects are worthwhile and which parts need to be revised, changed, or discarded. In the process, it may be possible to find glaring omissions that, on paper, weren't noticeable.

Additionally, creating a prototype will allow the design team to not only evaluate, but also test the product before going into full production. Imagine ordering tens of thousands of units, only to discover one part isn't as strong as it needs to be. By prototyping before production begins, it is possible to take a glimpse at the production process and see if any steps can be changed, combined, or even removed, therefore not only streamlining production, but keeping costs of the actual production to a minimum. Subsequently, if there are any difficulties in production or perhaps processes that can create problems for the final product, it is much better to see these before production starts. It can also help the design team ascertain the optimal method for production; injection-molding, silicone molds, die-cast, stamped metal, machine shops, etc.

Selling the Product to Others

Just like it is far easier to see if there are any problems with a design by holding an actual working model, it is also far easier to sell to potential customers when they have a prototype to hold and manipulate at a marketing presentation.
