Anyone who is involved in the world of plastic injection molding knows that it can often be a complex and confusing process. With over 60 years of experience and expertise in the industry, The Rodon Group has developed several eBooks and white paper on our website for those looking to expand their knowledge of this manufacturing process.
Plastic injection molding has a language all it’s own and with so many unique terms it can be difficult to learn the language. We put together a list of the top terms to know when discussing plastic injection molding, mold parts, materials, and problems. We hope you find this to be a useful resource.
When working with any manufacturing process, a number of defects unique to that process commonly occur. This is true across many processes and industries, including injection molding and high volume injection molding.
As we have previously discussed on this blog, there are several common injecting molding defects; however, an injection molder who is vigilant about quality, like our team at The Rodon Group, will be able to manage these injection molding defects, minimizing or eliminating them all together.
Earlier last year, we discussed 3D printing. Though it has been around for quite a while, the new printing technique has only been a player in the public consciousness for about five years.
In that time, the public’s perception of what 3D printing can do has eclipsed the process’ actual capabilities. And with more recognition come more inquiries — everybody wants to explore 3D printing as an option for their next project, and are eager to want to move on from more traditional methods, such as injection molding.
3D Printing and Injection Molding
The two processes are similar — they both primarily produce parts and components from plastic, and they are both capable of high degrees of geometric complexity. However, there are important differences as well.
One of the more appealing aspects of 3D printing is the absence of steep initial costs. Because of its need for specially tooled dies, the creation of which is an expensive process, injection molding requires considerable initial costs. Though imposing at first, these startup costs are amortized over the lifespan of the die and the production run — in high volume injection molding projects, the startup costs are amortized over more individual parts, leading to a relatively low per-part cost.
Manufacturing plastic injection molded components in-house as part of an end product can prove to be a major challenge from an efficiency, quality and cost perspective. Over the years, Rodon has garnered many of our largest customers who were doing their best to manufacture their injection molded components in-house but found the process to be problematic and inefficient.
At Rodon, we manufacture billions of parts every year and have done so since 1956. We are proud to have earned a reputation for being one of the best in the industry, offering high-quality, low-cost solutions. When businesses have a need for high volume, high tolerance, intricate parts, they turn to custom plastic injection molding.
The number of polymer compounds has grown over the past 20 years. As a result, plastics are being used in more applications than ever before. These materials are gaining a reputation for strength and endurance. Combine these improvements with the advantages of corrosion resistance and aesthetic appeal and plastics are taking center stage in the manufacturing of many consumer and industrial components. Due to their versatility, strength and light weight characteristics, plastics are also taking a larger role in the transportation, medical and construction industries.
Here are five requirements to keep in mind when choosing your resin:
There is an enormous amount of content out there for us to read every day. Figuring out which of it is worthwhile of your time isn't an easy task. If you are looking to stay up-to-date, blogs are rich with helpful, educational and useful information and tips. We hope you enjoy reading our blog and that we can help keep you informed on the topics of plastic injection molding, manufacturing and STEM careers.
Below we've compiled 12 other manufacturing and plastics industry blogs (along with their Twitter names) to consider following on a weekly (or even daily) basis. Some of them are industry favorites, while others are our personal favorites. Let us know what you think and if you have others you'd add to our list.

Our eBook "An Introduction to Plastic Injection Molding" was developed with designers, engineers and purchasing specialists in mind. It is written to provide a basic understanding of plastic injection molding presses, processes and costs. Our goal is to make our visitors and customers more knowledgeable about what goes into making a plastic part.
