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 plastic injection molding and high volume injection molding.

In the weeks leading up to the start of the Rio games, the New Zealand sailing team, a strong contender for medals, had been hard at work training for a potentially race-costing scenario: a plastic bag, or other rubbish getting stuck to the boat. Guanabara Bay, where the sailing competitions will take place, is heavily and visibly polluted. Rio state officials have begun cleanup efforts that currently involve a single helicopter directing eleven rubbish collecting boats. However, they’ve also acknowledged that a real cleanup effort could take up to 20 years.
The last week in July was a hot one for the Philadelphia region, but it didn’t wilt the spirits of the employees at The Rodon Group and K'NEX as they hosted Secretary Hillary Clinton and Tim Kaine’s first campaign stop after the Democratic National Convention. Regardless of your party affiliation, this was a proud moment for our company, to be chosen to host this historic event, the first leg of a Presidential race never before seen in our country.
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.
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.
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.
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.

Walk down the aisles of The Rodon Group warehouse and the lights above activate as you approach. On the manufacturing floor, end-of-arm tooling knows the precise time to release the plastic for regrinding. These practices aren’t magic or new to many factories. What sets our company apart is the commitment to sustainable practices throughout the organization.
At The Rodon Group, we think our quality certifications such as ISO 9001:2008, HACCP and recently certified GMA-SAFE demonstrate our commitment to providing the best possible parts at the most competitive prices. However, our commitment goes beyond certifications. We have a staff of quality professionals whose sole focus is making sure we produce plastic parts that are as perfect as possible.
In the past, many businesses operated on the assumption that their vendors were in compliance with the latest rules and regulations regarding their industry. Technology and materials were limited, so buyers worked with manufacturers who could produce the best product often without clearly defined quality guidelines or parameters.
