Rapid Injection Molding

Rapid injection molding & Chinese injection molding

Rapid injection molding is exactly what the name implies, but multiplied by a factor of 10! It is hard to imagine that anyone could offer a service that can guarantee a fully functioning injection mold in a day or two, but that is actually the case.

This is precisely what rapid injection molding is all about. Rapid, as in very rapid! These molds are made of high grade aluminum and can produce anywhere from a few parts to thousands.

Personally, I have worked on many aluminum molds that produce high quality parts even after several hundreds of thousands of cycles. At first I was highly skeptical, but after several years of making injection molding prototypes, It became routine.

How does rapid injection molding work?

It works by automating as much as possible in the mold making procedure. By taking the customer’s 3-D model and automating the design and manufacture of the mold, the lead times are cut down to a fraction of the conventional process.

One of the central parts of the automation process lies in the design of the plastic part. By working with knowledgeable designers, many features, such as undercuts, can be minimized or eliminated.

Some of the features that must be considered are:Chinese injection molding

  • Part draft angles and radii
  • Ejection
  • Using straight pulls whenever possible
  • Simple approaches to side actions
  • The CNC milling process
  • Part size limits

Rapid injection molding PDF papers

You can find out everything you need by reading the PDF papers on rapid injection molding. They cover every aspect of the process and are very well made. Just click on the design volume you wish to read about.

What are the advantages of rapid injection molding?

  • A way to bridge the time gap between prototype and full production. If you need a working injection mold right now, this is the answer.
  • Short run production to get your product in the marketplace immediately.
  • Gives engineers a working model to approach a full-blown design for a production tool.

What are the disadvantages of rapid injection molding?

  • The aluminum molds are low production.
  • Works best for simpler parts with minimal side action and undercuts.
  • EDMmachining is eliminated, thus some detail may be sacrificed.
  • The entire core and cavity are high-speed CNC machined, often on 5-axis CNC machines, therefore the design has limitations.

Is rapid injection molding expensive?

Surprisingly, the cost is quite reasonable, though there is always a premium to pay for extremely quick turnaround. Typically though, the cost is much less than might be expected. This is due to the highly developed automation process of this type of mold making.

Conclusion

Rapid injection molding is a niche market segment of injection mold making. It serves a highly specialized marketplace, yet is very important withing the niche. The ability to get your injection molded plastic part to market in a matter of days is very valuable to the right company.

Aslo, the ability to bridge the gap between prototype and high production is a very useful tool for custom injection molders.

What Are The Best Plastic Injection Mold Components?

Plastic Injection mold components are a very important for Plastic mold manufacturers, but often overlooked part of the plastic injection mold making process. These would include things such as: ejector pins, core pins, leader pins, leader pin bushings, pillar supports, rest buttons, interlocks, and much, much more.

Why are high quality plastic injection mold components important?

Cost- it is nearly always cheaper to purchase a custom mold base and the accompanying components. Why waste your time on the “grunt” work, when the profits are in the mold making? Of course, there are certainly exceptions, but generally, it is more profitable to purchase a standard mold base and the related components.
Consistency- Since a good supplier will guarantee close tolerances, you can focus your attention on the cores and cavities, instead of more general machining. The profit is in the cores and cavities, so why spend time making something that can be purchased cheaper and made just as well, or perhaps better? Even if it costs a bit more, it still makes good business sense most of the time.
Delivery- a good supplier will deliver just what you want, on time. Plus, you don’t have to pay for the scrapped parts he made while filling your order. This is especially true if you need more than one or two pieces.
Flexibility and innovation- companies are constantly searching for new and better ways to make components and improve their applications. Think about lifters, for example: there are numerous clever ways of making lifters, each one better than the rest! Take advantage of this collective inventiveness instead of relying on what worked 20 years ago.
Good communication- using standardized plastic injection mold components is often a selling point. Some companies have “favorite” suppliers for their hot-runner system, for example. This also can make communication easier, since the features and sizes are catalogued and common.
There is very little reason anyone would make most of the injection mold components used in their plastic mold. There is simply no way that to justify making things such as ejector pins, mold base bushings and leader pins. However, there are always special cases where it is practical to custom manufacture components. Special ejector sleeves, custom core pins, custom lifters or unique slides would certainly fall under this category.

Even in special cases, it is often well worth checking to see if a custom manufacturer can quickly make your special component. This can free your skilled mold makers to focus on the core and cavity work.

It is fairly common to waste huge amounts of hours making a mold component that you later discover could be purchased from a reputable supplier. Sometimes the cost savings are quite substantial, get to know more information about plastic injection mold components please visit our company website to know more.
