The Importance of Design Engineering in Plastic Injection Molding

Posted by The Rodon Group Marketing Team

5/10/16 8:00 AM

Before you can manufacture a plastic part you need to have a solid design in place. Once done, you can build an injection mold to meet the product specifications. 

The role of the Design Engineer is critical in this process. They assess the part design and make modifications and recommendations based on key product requirements including product usage and function. The engineer will need to know:

  • How will the part be used? Is it a standalone product or a component of a larger assembly?
  • What are the dimensional and tensile requirements?
  • Does the part need to withstand elements, pressure, chemicals?

A plastic injection mold design is built with these criteria in mind. Mold cavities, vents and gate placement will vary based not only on the part design but the type of resin as well. Taking all of these manufacturing factors into account is a challenging task and one that requires a strong knowledge base, not only of mold design but the injection molding process as well.

Everyday items made using plastic injection molding

Posted by Jill Worth

Plastic injection molding is a process of forming plastic, a durable, resinous material into just about any form or fashion imaginable.  The first injection molding machine was invented and patented by brothers John and Isaiah Hyatt in 1872.  It resembled a large hypodermic needle, with a heated cylinder through which a large plunger forced the gooey mass into a mold.  Today the process is more complicated, although the basic principle of plastic being injected into a waiting mold is still the same. One of the biggest advancements has come by way of the materials used, and there are now thousands of different formulations available for making 'plastic.'

Injection Molds 101: Cold Runner vs. Hot Runner Molds

Posted by Jill Worth

4/26/16 6:00 AM

Every plastic part starts in a mold. Injection molds are classified into two main types, cold runner and hot runner. Each has its advantages and disadvantages. Your plastic injection molder will be able to give you the costs and benefits of using these different systems. However, by understanding the key differences of these technologies, you can have a more educated discussion on the type of mold that would best fit your project.

The Importance of Sustainable Manufacturing on Earth Day and Every Day

Posted by Jill Worth

4/19/16 6:00 AM

The 46th anniversary of Earth Day is this Friday, April 22.  This year's theme is "Trees for the Earth" and as the Earth Day organization moves closer to its 50th anniversary in 2020, trees will be one of the five major goals and focuses set to help celebrate this social occasion.  The goal is to plant 7.8 billion trees, helping to combat climate change, breathe clean air and assist communities by providing food, energy and income. "On their own and together, these initiatives will make a significant and measurable impact on the Earth and will serve as the foundation of a cleaner, healthier and more sustainable planet for all.  Learn more about these efforts at http://www.earthday.org/earth-day/earth-day-theme/#sthash.wqdBmIy2.dpuf 


Over the last few decades, this new environmental awareness has grown, and it significantly impacts the way Rodon and other companies manufacture products. The increased focus on daily sustainable manufacturing has helped thousands of manufacturers save money, and the environment at the same time.

Plastic Injection Molding: Design to Part II

Posted by The Rodon Group Marketing Team

4/12/16 5:30 AM

In our last article on “Design to Part”, we focused on the importance of product function, the end-use application of a part and its impact on the final manufacturing process. We discussed the importance of providing details on the products function. 

These details include:

  • What elements will the part be exposed to?
  • What are the specific tensile requirements?
  • What chemical or corrosive materials does the part need to withstand?
  • What are the cosmetic characteristics of the part?
  • How long should the part last?
  • Does the part need to meet RoHS, FDA, REACH or other regulatory requirements?

In this article, we will discuss how the product function translates to the manufacturing process.

Exposing students to the "coolness" of manufacturing

Posted by Jill Worth

The need for talented manufacturing students is great

Last month, two of our Rodon employees, Dan Raymond and Matt Juckniewitz attended an annual local event called "Manufest". Dan is our Toolroom Foreman, and Matt is one of our Design Engineers. Manufest began last year as a way to get high school students interested in careers in manufacturing and to have a chance to meet with local manufacturers to learn about the companies and the types of jobs available to them after they graduate. This particular event was sponsored by the Montgomery County Commerce Department/Montco Works in partnership with the Bucks/Montco Alliance, Bucks County Workforce Development Board, Montgomery County Community College, and the MidAtlantic Employers' Association.

Plastic Injection Molding: Design to Part

Posted by The Rodon Group Marketing Team

3/29/16 6:00 AM

The concept of “Design to Part” is nothing new.  It is the manufacturing cycle of any product. But the journey from developing a product concept to a final part involves understanding the product function as well as its manufacturability.

In this three part series on “Design to Part”, we will begin by looking at product function and the role it plays in creating a finished plastic injection molded part.

Product Function

Plastic injection molding professionals obsess over the end-use application of a part. Very often they are responsible for making only one component of a final product. It is important to know what role the component part will play in the completed product. Without having this knowledge, you can almost guarantee part failure.

10 Must-Ask Questions for Choosing a Plastic Injection Molder [PDF guide]

Posted by Jill Worth

3/22/16 3:47 PM

How often do you source an injection molder?  If you are like most companies and project managers, not very often.  Once you have selected an injection molder to work with you are likely to stay with them as long as they keep producing quality plastic parts. 

There are several scenarios in which the need for an injection molder may arise:

- Your company has designed a new product that requires injection molding

- Your engineers have redesigned an existing injection molded part

- Your current injection molder is no longer meeting your quality requirements

- Your business is moving manufacturing closer to home
