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 [...]

I hope the end of the year is treating you well. We have had a few conversations with customers recently regarding shut off angles, and I wanted to get one final post out to everyone this year to briefly discuss the subject. A shut off angle is where two parts of the mold shut against each [...]

Last month’s design tips discussed how draft angles are specific to each part that is built.  This month we will look at some standard injection mold resins and some of the properties that they possess. When deciding which molding resin to use, one must consider the mechanical properties, molding properties, and cost of the resin selected [...]

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 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 [...]
