In times of COVID-19, medical plastics have never been in such high demand. From syringes to face shields, the plastic injection molding industry has had its hands full. Since medical utensils and devices are essential for performing life-saving tasks, not only do they require complex designs and functionality, but they also need to withstand a variety of medical environments, many of which include harsh chemicals and sanitation. To understand the safety precautions applied to injection molding, let’s take a look at the benefits of chemical-resistant resins in medical plastics.

Everyone witnessed the Ever Given causing a six-day traffic jam in the Suez Canal this March. Even with the cargo ship dislodged, it’s creating a nightmare of logistical issues for manufacturers. While the holdup didn’t affect Midstate Mold, it has further revealed how delicate supply chains are that utilize international transport, such as resin shipments or tool relocation. Given the fragility of logistics underlined by the Ever Given, let’s look at how to shorten supply lines in plastic injection molding to avoid undue production and distribution delays.

A part’s geometry, appearance, and performance can be largely impacted if a manufacturer doesn’t properly determine the shrink rate of the final product. It’s inherent in the plastic injection molding process, and if not accurately accounted for, it can result in timely and costly production line disruptions. Despite calculating the shrink rate, sometimes excessive shrinkage can occur, leading to further issues. Since it’s a complex process, let’s take a look at how and why plastic injection molding shrinkage affects the final product and the methods manufacturers use to compensate for it.

Many believe prototyping is just an extra, unnecessary step in the injection molding process, which is a misconception that can result in severe production line disruptions and forfeiture of time and money. In fact, some believe it increases costs and inhibits development and production times, but in reality, it does the opposite. Proceeding with a custom injection molding without prototyping often results in a series of tool adjustments that can become both time-consuming and expensive. Let’s review precisely how prototype tooling in injection molding accelerates production and saves you time and money.

Warpage can be one of the more frustrating injection molding defects, as it can range from a simple aesthetic problem to an issue that compromises the entirety of the part’s function. This defect can result from any number of variances occurring within the injection molding process. Fortunately, a combined knowledge of plastic flow behavior, material science, and machine and tool settings can prevent this defect. Let’s discuss how experienced manufacturers avoid warpage in plastic injection molding.

A frustrating combination of disrupted supply lines from the global pandemic and the recent storm that devastated Texas has led to limitations in resin availability. As with any industry, this is creating a disparity in supply and demand, resulting in soaring plastic prices and force majeure declarations – meaning an inability to fulfill a contract due to an unforeseeable circumstance. This has led to some vendors revising part specifications or material requirements to sidestep the crisis. Let’s take a closer look at the recent and frequent force majeure declarations and their effects on plastic injection molders.
