Let’s discuss one of the potential pitfall of designing for the process of injection molding. Melting plastic pellets and molding them into a part seems like a rather simple endeavor; however, it’s sometimes anything but. There are many factors to consider, and this month, we are going to talk about one of the more common: [...]

When working with metal, whether it’s cutting a tool or machining a final part, some features are too small to produce using traditional machining methods. For these applications, a process called electrical discharge machining (EDM) is used. EDM is also referred to as spark machining, spark eroding, burning, die sinking or wire erosion. What is [...]

Injection molding is the manufacturing process that is responsible for producing most of the plastic parts that you and I come in contact with each day. While the process is capable of producing a vast range of designs, it can take some time and therefore does not lend itself well to changes down the line. [...]

A common design feature seen in injection molded parts is the use of lettering and logos. Designers use this feature for many reasons; to illustrate a brand identity, convey important end user instructions, aid in assembly, or display a part number or legal warning. The injection molding process allows lettering and other surface decorations to [...]

Injection molding is the most common manufacturing method for producing plastic parts in the world. The purpose of these parts can range from a picture frame that is never touched to a gear that is used in a moving assembly every day. Many times, the stiffness of a part must increase due to the load [...]

By definition, an injection molding gate is an orifice through which the molten plastic is injected into the mold. The type and size of the gate plays a very significant role in the process of injection molding. Gate Types There are two types of gates available for injection molding; manually trimmed and automatically trimmed gates. [...]

Each injection mold design must have a gate, or an opening that allows the molten plastic to be injected into the cavity of the mold.  Gate design and location can have a drastic affect on your part that could result in incorrect parts and/or significant cost increase to fix your tools.The Affects of Gate LocationGate [...]

Have you ever wanted to create the look of a different material on a plastic part? Plastic parts not only benefit from designs that are pleasing to the eye, but they also benefit from the way a part feels when handled. Depending on the application, you may want your part to be as smooth as [...]

Designing plastic parts is a complex task involving many factors that address a list of requirements of the application. “How is the part to be used?” “How does it fit to other parts in the assembly?” “What loads will it experience in use?” In addition to functional and structural issues, processing issues play a large [...]
