Customer Testimonial 

"Very good experience!
I appreciate the online 
quote process, it helps me quickly define how I need the part built. Your customer service is great. Several other engineers that I work with saw the samples, were very impressed and all wanted to know where I had 
them made.”

J.W. @ Micron Technology

Monthly Spotlight: How Do I?...Tips from the Pros
:: Injection Molding: The Art & Science of Overmolding

Have you ever wondered how these items were made?

    

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 elastomeric) is molded “over” a secondary “substrate” material (usually a rigid plastic or object).

Overmolding can add immeasurable value to product design by enhancing the end users experience in terms of comfort, ergonomics, and ease of use. In order to achieve this level of manufacturing there are two important concepts that must be understood for success to take place:

1. Know Your Materials 

The materials used need to be compatible so that your designs attain a high level of molecular adhesion. Know what the melt temperature is of your substrate and overmold. If the melt temperature is lower on your substrate than your overmold material, then you are in for a big problem! Also, if you are using color, make sure your color concentrate is compatible with your other materials and won’t degrade their properties. Using the right materials could make or break your designs.

2. Understand Your Designs 

When designing, you need to consider how much or how little you want your substrate and overmold to stick. Don’t count on the material alone to create the adhesion that you want. To ensure that the components “mesh” well with one another use mechanical interlocks. 

Knowing the proper rules for overmolding can yield a very successful and aesthetically pleasing product. Feel free to contact your Tooling and Production

What’s NEWS at Quickparts
:: NEW TangoPlus Rubber-Like Material Offering for Rapid Prototyping

Quickparts is now offering the new TangoPlus rubber-like material for use in Rapid Prototyping. This new material offers exceptional elongation at break, excellent strength, and a high resistance to tearing. It addresses a broad range of prototyping applications requiring rubber-like flexibility and durability, such as gaskets and hoses, seals, athletic toys, footwear and more.

TangoPlus offers an unmatched combination of mechanical properties that sets a new standard in rubber-like performance. At 218%, the elongation at break of this material is more than double that of any other rapid prototyping material available on the market. It is highly resistant to tearing and has a Ross Flex measurement in excess of 150,000. Thus, TangoPlus offers outstanding resistance to deterioration, making it ideal for models that are likely to be exposed to long use or rough handling.
