Since the 1940's, demand for high-volume, low-cost manufacturing has increased dramatically. One of the best ways to produce many parts that are dimensionally the same is through plastic injection-molding. And as advances in materials and mold making technology continue, injection molding will increasingly become the manufacturing choice. This article will discuss the application of injection molding for prototype validation and manufacturing.

It is difficult to imagine a world without plastic injection molded parts. From the smallest keys of a cell phone to the plastic furniture on a porch, plastics are everywhere. New materials are being developed all the time that are stronger, more resistant to chemicals, and function at higher temperatures, allowing designers to utilize injection molded plastics where they would have used metals or ceramics before.

Mold making technology has also become more sophisticated, making it faster and less expensive to create injection molds. Because the traditional cost of injection mold tooling has been high, many components have been produced using other processes with much higher piece-part cost to avoid the tooling expense. Machining and hand-casting can produce similar parts, but part-to-part dimensional deviations are more likely and the labor involved increases the price. http://cadmodels.org/?q=liquid_plastic_injection_molding
