What are threaded inserts? Threaded inserts are small, often cylindrical, parts that you can insert into a hole in a plastic part during the molding process to provide a threaded hole for a screw or bolt. Threaded insert design typically uses metal, such as steel, brass, or aluminum inserts, and comes in various thread types […]
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 […]
Durable Plastic Product Designs Plastic parts need to be durable enough to handle the stress and wear and tear that the final product will go through when a consumer uses it. Using a gusset structure, rib parts, the right materials, and thick enough walls will give the plastic product the durability it requires. These are […]
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 […]
Acrylonitrile butadiene styrene, ABS, is a common thermoplastic polymer plastic used in injection molding. It is relatively inexpensive and easy to mold. This sort of process is usually used in consumer goods and pieces for electronics. ABS injection molding is not resistant to sunlight and weather, so this choice may not be the best solution […]
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 […]
