We often field phone calls from inventors or product designers who are looking for a plastic injection resource.  While, that is our core business, it is important to understand the difference between The Rodon Group and other small injection molding companies.

We specialize in high-precision, high-volume projects (we're talking millions, here).  To get a better understanding of the capabilities of The Rodon Group, we created a Q & A filled with useful information.

What are the minimum quantities you can order?

The process of plastic injection molding has been around for years.  And over time injection machines, resins, and mold-building technology have greatly improved.  However, the basics still remain the same.  You take plastic pellets, melt them, and fill a mold with the melted plastic; the result, once cooled, is a plastic part.

Types of plastic molding

Posted by Paula Hynes

7/30/14 1:30 PM

In today’s manufacturing environment, plastics are being used to make everything from automotive body parts to human body parts. Each application requires a special manufacturing process that can mold the part based on specifications. This article provides a brief overview of the different types of molding and their advantages and applications.

Blow Molding – Well suited for hollow objects, like bottles

The process follows the basic steps found in glass blowing. A parison (heated plastic mass, generally a tube) is inflated by air. The air pushes the plastic against the mold to form the desired shape. Once cooled, the plastic is ejected.
The blow molding process is designed to manufacture high volume, one-piece hollow objects. If you need to make lots of bottles, this is the process for you. Blow molding creates very uniform, thin walled containers. And, it can do so very economically.

Compression Molding – Well suited for larger objects like auto parts.

The name of this molding method says everything.  A heated plastic material is placed in a heated mold and is then compressed into shape. The plastic can be in bulk but often comes in sheets. The heating process, called curing, insures the final part will maintain its integrity. As with other molding methods, once the part has been shaped, it is then removed from the mold. If sheeting plastic material is used, the material is first trimmed in the mold before the part is removed.

This method of molding is very suitable to high-strength compounds like thermosetting resins as well as fiberglass and reinforced plastics. The superior strength properties of the materials used in compression molding make it an invaluable process for the automotive industry.

Extrusion Molding – Well suited for long hollow formed applications like tubing, pipes and straws.

While other forms of molding uses extrusion to get the plastic resins into a mold, this process extrudes the melted plastic directly into a die. The die shape, not a mold, determines the shape of the final product. The extruded “tubing” is cooled and can be cut or rolled for shipment.

Several years ago, we began a search for a local resource to help us with some project work and we found ourselves visiting the Indian Creek Foundation/ICF Solutions located in nearby Souderton, Pennsylvania. ICF Solutions, a division of Indian Creek Foundation offers a facility-based work program for residents throughout Montgomery County. Since 1975, the Foundation’s mission is to “provide opportunities for people with intellectual and developmental disabilities; to live in and enrich the community throughout their lives.”  The foundation also provides supervised housing, life support services as well as behavioral health programs.

How to Achieve Perfect Plastic Parts

The adage “If it can go wrong, it will go wrong” should never be true in the world of injection molding.  In fact, problems can be easily avoided from the very beginning as long you are working with a turnkey precision molding manufacturer.  Some companies opt to use an outside design firm to design the mold, then contract another vendor to build the mold (often these were offshore mold builders) and another to run the parts.  By separating these responsibilities, they often sacrifice control, accountability and quality.

Buy American-Made Products to Celebrate July 4th

Posted by Paula Hynes

7/3/14 10:30 AM

Starting this holiday weekend, we encourage everyone to start a tradition of buying American-made products. Just like the nutrition labels on food that tell you about the contents of the product, country of origin labeling tells you where the contents came from and where they were assembled. With a few exceptions, the government does not require this labeling; however companies are proud to display their Made in the USA origin. These businesses understand American consumers want to purchase products made here and support jobs throughout our country.
