What do a leather wallet and a ketchup bottle cap have in common? You got it…they both implement the living hinge to bring the object to life through movement. When speaking in terms of manufacturing, a living hinge is a thin flexible web of material that holds two rigid plastic pieces together. The living hinge [...]

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 [...]

Draft and wall thickness are two of the most critical and overlooked fundamentals when manufacturing and designing for injection molding.DraftDraft is a design feature that involves tapering the side walls of a part to allow it to be released from the mold when the mold opens. Drafting walls in the direction of the mold helps [...]
