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 […]
What is a sprue? A sprue is a channel through which molten plastic flows into the mold. The sprue is specifically the entry point of the molten plastic, the vertical passage which then flows through runners and gates, but in general, the entire assembly is commonly known as the sprue. The whole system is easily […]
Manufacturing plastic prototype – where to start The first step in every product’s life is prototyping. Whether it’s a brand new idea or an improvement on an old design, prototyping allows designers to see and test a product before it goes to production. From consumer goods to industrial, every field across every industry benefits from […]
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 […]
