Keeping an even temperature on the surface of an injection mold has been a constant challenge. Manufacturers have used baffles, bubblers and heat pipes; they’ve glued blocks together and added detailed drilling set ups to their molds in order to maintain a constant temperature. Over the last ten years, conformal cooling — designing cooling channels [...]

One of the most common questions we are asked is “How much draft do I need for the texture that I want?” The general rule of thumb is that you allow for 1.5 degrees of draft for each .001″ of texture finish depth. However, there are other considerations that must be taken into account due [...]

When it comes to rapidly manufacturing injection molded parts, there are several key factors to consider. Here are a few of the top considerations to start off on the right track: Design All successful injection molding programs begin with proper design for the process, and in this case for rapid production. When designing your part [...]

Selecting an appropriate material is, perhaps, the most important factor when implementing a design for injection molding. With literally thousands of different resin grades to choose from, an erroneous choice can prove to be disastrous. Thorough research and consultation is strongly advised, especially for anyone new to plastic part design. A simple web search, along [...]

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 [...]

We have some great ways to help you save money on your next injection molding project. :: Top 5 Money Saving Tips 1. When selecting a material for your injection molded part, do not just assume that you need a material that has the best properties. A lot of people overcompensate by selecting materialsthat they don’t [...]

If you’ve ever wondered if draft angles were a must, we’ve got the answer for you! The justification for draft angles comes from the nature of the injection molding process, and the ever present issue of mold shrinkage. Injection molding is a high-pressure process. These high pressures force the plastic into intimate contact with all [...]

Have you ever wondered how these items were made?? The answer is overmolding. The overmolding process involves the use of two separate materials to form one cohesive component. The most common type of overmolding is insert molding. Insert overmolding is an injection molding process where one material (usually elastomeric) is molded “over” a secondary “substrate” [...]
