Here at Quickparts, we are in constant contact with engineers, mold makers, machinists, and other self-proclaimed experts of the manufacturing industry. Over the years, our molding lexicon has grown tremendously – to a “molding urban dictionary” of sorts. Listed below are some of the most common terms that frequent our ears daily. What did we [...]

Design engineers don’t have to be fluid dynamics experts to injection mold plastic parts without a hitch. Pitfalls associated with flow dynamics can still be averted through the use of simple designs and by following general guidelines. The following rules will help engineers avoid problems when designing injection-molded plastic parts: Rule 1: Keep Wall Thickness [...]

We got a great response to last month’s money saving tips post. For this month, we wanted to provide you with 3 easy steps to ensure the success of your next tooling project. Step 1: Get a Design for Manufacturability (DFM) Analysis Most tool shops have the ability to provide some form of Design for [...]

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 [...]

We learned last month that selecting the optimal gate size and location is vital in the creation of any molded part. However, that is just half the story. Just as pivotal to the success of the design is the type of gate that is used. There are actually four main types of gates that are [...]

“Out of which material should you build your mold, steel or aluminum?” This is a very common question that we receive from our injection molding customers and is an important decision to make. The answer is usually dictated by your project requirements, expectations, and what ultimately defines “success” for your project. QC10 aluminum is an [...]

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 [...]
