Rapid Injection Molds

When discussing production processes like how injection molded plastics are made, there will obviously be short-cut processes that utilize the basics of the original but are able to do it faster and for smaller quantities. There are a number of reasons that a method like this, such as Rapid Injection Molds or rapid prototype injection molding, is necessary. When a company is developing a new product, they need to create prototypes to test before they run a full-line production. Sometimes a company needs a limited supply of products that are significantly fewer than the average number in normal mass production. With situations like these, the quickness and cheapness of rapid injection molding for limited production are more worthwhile for the injection molding company as well as the customer company getting prototypes or limited products produced.

In short, rapid mold or rapid injection molding is essentially the same process as normal injection molding, just done on a smaller scale with cheaper and less expensive molds. The quality of the mold matters because a mold used for mass production of a product needs to be in excellent condition because it will be injected with plastic then cracked open when the plastic is hard repeatedly and needs to keep its shape exactly that entire time. A mold like that takes a lot of time to get perfect and is therefore not appropriate for short runs like Rapid Injection Molds.

Although the process is quicker, cheaper and produces fewer products, it still deals with the same quality thermoplastics to create prototypes and short run productions. For example, nylon, ABS, polycarbonate, polypropylene, and polyethylene are all commonly used within the rapid injection molding process. Industries that utilize the cheapness and quickness for new products include the medical field, automotive, electronic, aerospace, and appliances, for a variety of specific products such as gears, toys, and enclosures.

What is Rapid Injection Molding?

Rapid injection molding or rapid tooling injection molding is a popular manufacturing technique that has been idolized for years.  Rapid injection molding is similar to conventional molding, yet different enough to affect how parts are designed. This technique lets companies quickly get low-cost and dimensionally accurate prototypes as well as low-volume production parts from plastics.

Rapid injection molding falls between rapid prototyping and conventional injection molding. This technique supports prototyping, bridge tooling, and low-volume production. Additive methods such as FDM and SLA work well for testing form and fit, but often such parts are not a substitute for testing with real injection molded partsRapid injection molding is also fast and cost-effective enough to fix problems when initial designs are not quite right.

Rapid injection molding has increased the quality of a final product by increasing the time companies have to test designs. Some manufacturers did quite a bit of testing with rapid prototype based polyurethane castings, but because the material properties of cast materials can differ significantly from those of injected molded resins, many times testing left unsolved.

What is What is Rapid Injection Mold or Proto mold?

Rapid injection mold and proto mold are two different terms that refer to the same thing. They both describe a type of mold used in rapid injection molding, which is a manufacturing process that allows companies to quickly produce small to medium-sized batches of plastic parts or products.

A rapid injection mold or proto mold is typically made from aluminum or soft steel, which can be created quickly and cost-effectively compared to traditional injection mold. These molds are designed to be used for a shorter period of time and for lower production volumes than traditional injection molding molds.

The use of rapid injection molds or proto molds in rapid injection molding allows companies to quickly produce prototypes or low-volume production runs of plastic parts or products. This process is faster and more cost-effective than traditional injection molding, which requires more time and expense to create molds.

Rapid injection molds or proto molds are a valuable tool for companies that need to quickly produce high-quality plastic parts or products for prototyping, low-volume production, or quick-turnaround projects.

Difference between Rapid plastic Injection Molding and production injection molding

The main difference between rapid plastic injection molding and production injection molding is the production volume and the lead time.

Rapid injection molding is a fast and cost-effective way to produce small to medium-sized batches of parts or products. It uses advanced software and machinery to create molds quickly and efficiently, which reduces the lead time and turnaround time. Rapid injection molding can produce parts or products in a matter of days or weeks, making it suitable for prototyping, low-volume production, and quick-turnaround projects.

Production injection molding, on the other hand, is a more established method of producing parts or products at a larger scale. It involves creating a mold and then injecting molten material into the mold to create the final product. Production injection molding is best suited for larger production runs and can produce high volumes of parts or products at a lower cost per unit. It is ideal for long-term production projects that require consistent quality and high-volume output.

Another difference between rapid tooling injection molding and production injection molding is the cost. Rapid injection molding has higher upfront costs due to the investment in advanced software and machinery. However, it can be more cost-effective for small to medium-sized production runs. Production injection molding, on the other hand, has lower upfront costs and is more cost-effective for larger production runs.

In summary, the main differences between rapid injection molding and production injection molding are the production volume, lead time, and cost. Rapid injection molding is faster, more expensive upfront, and best suited for small to medium-sized production runs, while production injection molding is slower, less expensive upfront, and best suited for larger production runs.

The technique of rapid tooling injection molding makes testing much more beneficial. It is because everyone knows that new products must pass extensive design, prototype evaluation, and functional testing before they are considered ready to distribute to markets. In this case, rapid injection molding becomes one of the best techniques for prototypes that need to undergo design changes during the developmental stage.

By rapid injection molding technique, you can make as many prototypes as possible needed to get the best products, or you can name it pilot production. It is perfect for market testing until the production plastic mold is ready, or about a three or four month wait. When production volume does not justify to make prduction plastic mold, this molding technique can supply production parts.

If you never knew the process of rapid injection molding, the following can help. The process uses aluminum molds milled on 3-axis CNCs instead of the expensive, hardened tool steel molds used with traditional methods. Molds comprise an A-side, sometimes called the cavity side and a B-side, sometimes called the core side. The A-side mounts to the fixed portion of the injection molding press.

Then, in rapid tooling injection molding, resin is injected through this section of the mold into the part cavity by way of the sprue, the path the resin takes until it reaches the runners. These guide the resin to the gate, the location where the plastic enters the part cavity. The B-side, on the other hand, mounts to the moving side of the press and includes the steel ejector pins. Before designing the mold, parts are oriented so they will remain on the B-Side when the mold opens.

The process of rapid injection molding also requires technology, such as 3D CAD with high speed CNC machining equipment to quickly manufacture injection molds. This way is efficient, as it enables the low cost creation of injection-molded prototypes and makes low volume runs of production parts affordable. It allows manufacturers to get prototypes in just few days. It is also a way company’s image since it lets you to have more preparation before launching products.
