Case Study: Plastic Injection Molded Display Components

Posted by Jill Worth

2/8/16 6:00 AM

Point-of-purchase display components require rugged construction in combination with an attractive appearance. At The Rodon Group, we injection molded a range of products, including items such as pegboard hooks, shelf dividers, and product stops for one of the leading companies in the point-of-purchase display industry. This project highlights our ability to provide value-added services in conjunction with close tolerance injection molding that equates to cost savings over the entire product lifecycle.

Working with the customer supplied prints, we first focused our attention on mold design. Our goal, as always, was to construct molds that would lead to volume high quality while minimizing production costs. By paying detailed attention to aspects such as cavity dimensions, gate location, venting, cooling systems, and more, we achieved optimal cycle times while upholding tolerances as close as ± 0.005” across varying complexities in part geometry. One critical feature of these parts was a fine quality surface, so we leveraged the capability of our EDM equipment. This allowed us to create a very fine finish on the mold cavities to add clarity and quality to the surface of the finished part with no extra processing required.



Production involved the use of various commodity and engineering grade resins in shot sizes from less that one gram all the way up to 35 grams. With part sizes measuring from from 5/8” square up to 3.5” in length x 19” in width, we used a variety of injection molding presses in the 46 to 233-ton range. Machine vision inspection right at the press, combined with a robust set of test and measurement processes, ensured we satisfied all of the quality requirements.

The Rodon Group was able to demonstrate that done right, a high-quality mold and plastic injection experience can result in better quality at a better price.

5 Manufacturing Leaders Who Contributed to Today's Advancements

Dr. Martin Luther King's contributions to the advancement of civil rights in this country defines the word "leadership". He was a visionary leader who was deeply committed to achieving social justice through nonviolent means. 

In celebration of Dr.King's birthday this past Monday, we thought we'd highlight past leaders in the manufacturing world who made very different but equally important contributions to today's advanced technologies.  Each of them had their own unique leadership styles with one important trait in common; they were all visionaries. They each saw the potential of creating a better, more efficient system or machine to complete a task. While the official “Industrial Revolution” may be over, our society still benefits from the work of these current day visionaries.

Manufacturing Methods of Plastic Molding (Including Infographic)

Posted by Jill Worth

1/5/16 5:00 AM

In today’s manufacturing environment, plastics are being used to make a wide variety of items, and each application requires a special manufacturing process that can mold the part based on its specifications. If you're looking to manufacture a plastic part, one of the first things you'll need to determine is the type of molding that would be best for your particular application.  At The Rodon Group, we specialize in high volume, custom injection molding. This article provides a brief overview of the 5 different types, their advantages and applications.

Blow Molding - suited for hollow objects, such as 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.
