INTRODUCTION TO RAPID INJECTION MOLDING
When engineers need to produce parts very quickly, they use what is aptly called “rapid injection molding.” injection_moldings01The parts produced in rapid injection molding are used for creating prototype parts for design analysis. While useful in that respect, the rapid injection molded parts typically aren’t used as a finished product but it can be a bridge to production that produces parts for production while the true production mold is being made. Instead of being a primary production process, therefore, rapid injection molding is more of a research and development process.

In order to be successful with this stage of the production of plastic parts, a few factors need to be considered carefully. Some of these factors are:

TOOL DESIGN

The natural first step in all injection molding processes, including rapid injection molding, is tool design. When tool design begins, the part formation has already been conceptualized, so there is an idea of how it will look and function, at least theoretically.

Part size and the intricacies within the part contribute the most to lead time, which needs to be reduced. The easiest way to get around the problem of large and intricate parts is compartmentalization: breaking the big intricate parts into smaller, less intricate parts and then assembling them in the end. Compartmentalization can shorten lead time because this technique prevents engineers from wasting time working on a very complex part.

Now that the big intricate part has been broken down into smaller, less intricate parts, engineers can use the rapid injection molding technique to machine the parts.

PART MATERIAL

To better take advantage of the quick turnaround time that rapid injection molding offers, one should look to make use of materials that are readily available or can easily be obtained from a retailer or a major distributor. Spending excess time looking for a suitable material negates the point of rapid injection molding. In addition, because the parts that are created with rapid injection molding are mostly made only to test parameters – such as confirming the basic design, function, and ability to reproduce the part, the type of material used can be unimportant. As long as the chosen material has properties similar to the final intended material, it will work.

In the unlikely case that the same material as the finished product is required for the rapid injection molding process, the material should be procured while the mold is being prepared by the CNC machine so as not to waste time.
