Causes and Prevention of Burn Mark Defects in Plastic Injection Molding

Close-up of a plastic injection molding machine.

The goal of every plastic injection mold and parts manufacturer is to have each mold and part come out without issue or defect. However, like with all manufacturing processes, these flaws can be introduced due to a myriad of situations. Today, we’re looking at the plastic injection molding defect known as burn mark defects—what they are, what causes them, and how your injection molder can help avoid it in the first place.

The Importance of Properly Dried Polymer Resin in Manufacturing

An often-overlooked part of the plastic injection molding parts manufacturing process, the use of a resin dryer is a key part of producing quality parts, every time. Today we’re going to look at how properly dried polymer resin in manufacturing can be such a big deal, how dryers fit into a larger plastic injection molding QA program, and how not all dryers are created equal.

Maintaining Critical Plastics Productivity While Increasing Sustainability

Man standing with green safety helmet in front of manufacturing site.

The continuing trend of sustainability in all aspects of manufacturing and industry is coming from the top in form of government regulations down to the bottom in terms of customer preference. This means you may need to change your own company’s sustainability initiatives, which can be challenging if your production relies on plastic parts. Today, we’re going to look at how you can maintain plastics productivity while increasing sustainability in your industry by working with the right plastic injection molding manufacturer.

Popular Resin Combinations for Plastic Injection Molding

Red and blue polymer resin in sample test tubes.

One of the major strengths of polymer resins in injection molding is the staggering array of plastics to choose from in the use of your part molds. There are plastics that are flexible, rigid, transparent, heat-resistant, strong, and other characteristics. Today we’re talking about another exciting feature: they are also combinable. Much like with metals, polymers can be combined to make new blended plastics with both or new strengths. Let’s go over three of the most popular resin combinations for plastic injection molding and where to go from there.

With the new year, it’s important to look back on the shortages of last year, their sources, and what they mean for 2023. While these last few years we’ve felt numerous shortages due to the pandemic and labor shortages, in 2022 we saw a new one with the outbreak of war between Russia and Ukraine causing a shakeup of hydrocarbon restrictions—specifically natural gas and other derived chemicals—through both sanctions and the ripple effects of the conflict.

3 Tips for Overcoming the Limitations of Plastic Injection Molding

Every modern manufacturing method has its strengths and its weaknesses. 3D printing may be fast and relatively cheap, making it great for prototyping, but it cannot be scaled up for mass production. CNC milling can produce complex parts out of very hard materials but at a high cost. There are limitations of plastic injection molding as well, but there are also ways to offset many of these weaknesses with a little foresight, especially when working with the right vendor early in the process. Learn our top three tips for getting your parts made with injection molding the right way.
