Benefits & Cost Savings of Outsourcing Plastic Injection Molding

Posted by Kevin Allison on Mar 18, 2020

The concept behind plastic injection molding is relatively simple — to inject heated liquid plastic substrate into a mold, allow the liquid to cool to a solid, eject and repeat. This simplicity lends itself to the versatility, efficiency and availability of injection molding, but it can also lead OEMs in need of plastic injection molded components to attempt to bring those processes in-house.

Almost always, these OEMs will find that in-house injection molding leads to unforeseen cost and logistics concerns, and quickly becomes a liability to the bottom line and even the product’s quality. Instead of bringing these processes in-house, the more productive step here is outsourcing plastic injection molding to an expert in the field.

Advantages of Outsourcing Injection Molding

When you hire another company for plastic injection molding, you gain access to several advantages. These include:

  • Outsourced infrastructure: The upfront investment for injection molding machinery is sizable. Injection molding machinery is typically built to undergo millions of cycles and near-constant operation, and the cost reflects this. If an OEM only needs to operate injection molding machinery intermittently, to produce smaller quantities, the length of time to recoup that investment stretches far more than is reasonable. When you outsource injection molding, you are able to make use of someone else’s investment, freeing your capital for core competencies, innovation and other areas.
  • Guaranteed expertise: With in-house injection molding, if it isn’t a core competency, you’re likely to be learning (and training) on the job — and thus paying for both of these processes. Part rejects and production errors come directly out of your bottom line, to say nothing of the time lost. With a molding partner, you are guaranteed to be working with an expert — while also freeing yourself of a training or hiring burden.

Top 5 Most Common Quality Defects in Injection Molding

Posted by Kevin Allison on Jun 05, 2019

Plastic injection molding is a very cost-effective method for mass production of parts – but even the best designs sometimes have shortcomings that result in quality defects. It is important to be familiar with these defects in order to identify and trouble-shoot them, as well as avoid them by developing a competent design! Below are the top 5 most common quality defects in injection molding and how each can be resolved. Additionally, for more information on these and other types of cosmetic defects see the glossary that was compiled by The Society of Plastics Industry.

Benefits of a Value-Add Supplier

Posted by Kevin Allison on Mar 27, 2019

Supply chain professionals are typically focused on creating a supply chain of trustworthy sources that can meet their product needs, but how can they get more than just a simple “shoot and ship” from their plastics supply chain? Injection molding suppliers have the opportunity to provide a significant value to their customers if they expand their capabilities to more than only injection molding.
