A common question for those looking to source plastic injection molder is “How much will a plastic injection mold cost?” It makes sense. The actual mold represents the greatest expense in upfront production costs. And, there are many factors that go into determining the cost.  With any custom injection molding project, your injection molder should be able to give you the final price tag. In this article, we will review the variables that can impact the cost so that you can be better informed when making a mold purchasing decision.

Our website is frequently visited by product designers, engineers and purchasing agents who are looking for information on plastic injection molding. With this in mind, we created a series of "Basics 101" type articles that are developed to give our readers a better understanding of the presses, processes and pitfalls in our industry. 

We begin our series with information on the basics of plastic injection molding presses. We hope you find this information useful.  If you have specific questions, please do not hesitate to contact us.

Injection Press Basics

While plastic injection molders will help you determine the size of the machine needed to get the best result, a project designer or engineer can get a good estimate based on some basic information. By knowing approximately what size machine will be required, you can better source a plastic injection molder that will meet your needs.

A Low Maintenance Approach to Mold Care

 "The time and care you invest in upfront maintenance will keep costly repairs at bay."

 Let’s face it, our parents were right.  Take care of your things, and they will last a very long time.  It was a matter of necessity.  Back in the day, products were made well and made to last as long as you didn’t abuse them. The same is true in a manufacturing environment.  Take care of your equipment, and it will take care of your production needs for a long time. 

 In the plastic manufacturing environment, the key to consistent quality parts is to start with a quality, well-made mold. We call this our “low-maintenance” approach to injection molding. We begin the process with a solid mold design and a high-quality tool build.  We run prime resins on some of the best machines available.  All of these factors impact quality.  According to Lowell Allen, Sr. Vice President of Manufacturing at The Rodon Group, “When running a 24/7 operation, you can’t afford to have shoddy workmanship.”

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.

How to Achieve Perfect Plastic Parts

Posted by Paula Hynes

7/9/14 10:03 AM

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.
