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 [...]

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 [...]

So what is Design for Manufacturing? Why do I care? These are a couple questions we hear in the development phase of a new product.  The brief description according to wikipedia.com is that DFM is the general engineering art of designing products in such a way that they are easy to manufacture. The basic idea exists in [...]

One of the ways that companies have been able to reduce lead times for new injection molds is to use quick change mold systems.  This typically means that there is a common mold frame that is stationary in the molding machine and the only part being constructed is the core and cavity inserts.  This system creates [...]

Have you ever wondered how a screw driver is manufactured?The answer is overmolding. What is it? The overmolding process involves the use of two separate materials to form one cohesive component. There are two types of overmolding: insert and “two-shot”. Insert overmolding, the more popular process, is an injection molding process where one material (usually [...]

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. A living hinge is a thin flexible web of material that holds two rigid plastic pieces together. The living hinge concept has been around for years [...]
