Plastic injection molding is a process in which molten plastic injects into a mold cavity, then it cools down until a solid part forms in the shape of the mold. There are many factors that make that process specific for each part, and one factor to consider is how many cavities a mold uses. H2: […]
Living Hinges: What Are They & How Do They Work Living hinges are a function built into some injection molded plastic parts. In this article we will learn more about live hinge design, live hinge material options, and other aspects of live hinge injection molding. What is a living hinge? A living hinge allows a […]
What Are Knit Lines In Injection Molding? What are knit lines? Knit lines, weld lines, mold lines, or flow lines in injection molding are faint lines that become visible on certain plastic parts. Weld lines may appear like seams or scratches, but that is not what they are. Wavy lines are another feature of weld […]
What is the Parting Line in Injection Molding? An injection molding parting line is visible on all injection molded plastic parts. The two halves of a mold create a parting line between them when they clamp shut. While molds need to seal completely during the process, a thin visible line can always still be found […]
What is Plastic Injection Molding? To create plastic parts, manufacturers use a process called plastic injection molding. Plastic injection molding involves injecting molten plastic into a mold to form the product. The plastic then cools in the shape of the product, creating the final product. Once you understand what plastic injection molding is, you can […]
From toy LEGO blocks to space shuttle turbine blades, plastic injection molding touches our lives every day. But what is plastic injection molding? Why is it so popular? And is the process right for your manufacturing needs? What is injection molding? Injection molding is a common manufacturing process for producing large volumes of parts […]
Low-volume injection molding is the best option if you are looking to make parts in quantities of 100,000 or fewer. It’s used for mass-producing identical parts before committing to a long-term molding setup, whereas other parts may never need to be produced in higher volumes. This form of molding is one of the most common […]
What’s the best way to make sure that your injection molding is cost-effective, efficient, and consistent? Short-run molding! This specialized process involves using molds made from less expensive aluminum or steel. You can expect many of the same benefits of injection molding when producing small runs without sacrificing quality or performance; it’s an easy choice […]
Injection-molded plastic parts Injection molding can create parts used in all sorts of projects and industries. From cars to computers, motorcycles to models, plastic injection molding is how modern products get made. In fact, plastic parts made with injection molding surround each of us every day. Plastic parts are so appealing to businesses because […]
Injection molding material cost If you spend $20,000 on a steel mold and then use that mold to create 400,000 parts, the cost per part would end up at 5 cents. There’s more to it than that, however, as the labor and material used will also have an impact on the total investment. Common injection […]
