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 […]

Prototype mold for small plastic parts with the parts besides the mold.

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 […]

example of small toy model pieces that show the lines formed by sprue.

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 […]
