COVID-19 has been longer-lasting and more resistant to preventative measures than previously imagined. However, manufacturers and their clients now have a new tool to help in the fight against the epidemic and other harmful viruses and bacteria. Plastic injection molding has long been seen as an effective means for creating high production, quality parts for the medical field, and with the new method of including antimicrobial and antiviral additives in the plastics, it’s serving an even greater purpose.

Discoloration in injection molding is defined as a disparity in the original color of the plastic. This part defect can arise from a multitude of sources, such as overheating, contamination, or manufacturing error. This inconsistency in the part’s coloring is caused by thermal degradation, and depending on the severity, it can influence how noticeable this defect is. In order to avoid this complication, one must first understand what can cause discoloration in plastic injection molding.

When you entrust your injection molding production to a manufacturer, you’re entering a partnership. Justifiably, you want your manufacturing vendor to consistently meet your expectations, provide timely output, and add value to your projects. However, if you’ve found yourself in a lopsided partnership that has eroded your confidence in them – through poor-quality part production, unfulfilled orders, or other unsavory activities – it’s time you seek a business elsewhere. But first, you need to know what to look for in injection molding manufacturers.

The act of prototyping is typically performed to test various part designs to create the best product, and sometimes it’s required to show multiple design elements to prospective investors. Regardless, prototype development is integral to the plastic injection molding process, as the final product should mirror the designer’s image. However, there are often time constraints on part manufacturing, so individually prototyping different molds can be wasteful. That’s where rapid part prototyping comes in to play.

Multi-Cavity Molds vs. Family Molds: Which Best Serves Your Needs?

A close-up picture of a multi-cavity plastic injection mold with four similar parts inside, meant to serve as a comparison between multi-cavity molds and family molds

The process of injection molding involves plastic being inserted into a hollow mold cavity. The finalized product takes on the shape of the desired part. However, what if your project requires multiple plastic parts? Designing and building several molds is expensive and time-consuming, which is where multi-cavity molds and family molds come into play. In this blog, we will discuss the difference between the two and how to determine the best option for your needs.
