Molded Dimensions is Essential Business: Open and Shipping Product.

The Coronavirus situation continues to change daily. Here are the updates from Molded Dimensions.

1) Employees: We are initiating work from home for positions where this is possible. Our manufacturing employees, and other essential staff, in Wisconsin continue to report for work and production continues as normal. In addition to regular workplace sanitizing, we continue to provide ways to social distance ourselves and reduce cross-contamination between departments and facilities.

2) Raw Material Supply: We continue to monitor our supply base to assure our raw material stock is available to provide uninterrupted supply for our customers.

3) Production Commitment: Our manufacturing employees are considered "Essential Critical Infrastructure Workers." We do not plan to shut down manufacturing and shipping unless required to do so by governmental restrictions.

Best regards,
Patrick Roddy

Chemist’s Corner – Part II: Success From Failure

September 7, 2021

“Failure is success if we learn from it.” — Malcomb Forbes

When a component fails, it is imperative that the root cause of the failure be determined quickly and accurately, and that proper corrective measures be taken in order to prevent future occurrences. When Molded Dimensions is asked to provide an estimate for a part that is not meeting the expectations of a customer, they will request samples of the part and take it through a simple five step process:

Chemist’s Corner — Why Parts Fail

July 27, 2021

This is the first of two articles about parts that fail and why. Rubber components are generally known for their durability, elasticity, strength, and reliability. However, when subjected to certain conditions, the rubber material is susceptible to fatigue and failure. These can be avoided through proper testing and good chemistry, but if a part does fail to meet your performance expectations, how do you determine why?

Technically, there are a number of possible causes related to a rubber part failure, but three leading indicators would come from knowing the component’s working environment, tolerance for temperatures, and mechanical performance. Let’s look at each area:

PU Design Suggestions

April 29, 2016

urethanedesign1c2We take pride in designing the best possible polyurethanes the industry has to offer, and that is due to the strict guidelines and standards we set for our self.

Sharp Edges
Sharp edges or corners, externally or within the polyurethane part, should be avoided, particularly where the polyurethane is stressed.

Silicone Products Can Be Found All Around Us

January 27, 2016

silicone-partsSilicone rubber is an elastomer that combines silicon, carbon, hydrogen, and oxygen.  It is a material that maintains its properties at very high and low temperatures, making it desirable for use in many applications.  Because of this, you see silicone used in your everyday home life in the kitchen as spatulas, and even oven mitts. In the office, Postit® note utilizes silicone-based adhesive systems.  This material offers such diversity that it is also used in many industries including automotive, medical, and power distribution, along with many more

History
Dating back to ancient times, the Romans used silicon-based sand to make glass.  In the 1930s, Chemists of Corning Glass and General Electric are credited as having created the first silicone polymers.   Recognizing the potential of the polymer, Corning Glass and General Electric spun off a group called Dow Corning in 1943 to continue the development of the material, which we use today.

Design For Manufacturability: Rubber and Cast Polyurethane Raw Material Selection

December 14, 2015

13-046_362One of the most important items in the design for manufacturability process is selecting the lowest cost rubber or urethane material capable of meeting the application requirements.  Design Engineers are often not elastomer experts, although they have the most direct impact on part cost.  Certainly you could choose a fluoroelastomer for a simple wire grommet application in ambient temperatures with no chemical or fluorocarbon exposure, and it would function.  But why would you spend upwards of $15 per pound on material when you could spend $3 per pound to do the same job?  Molded Dimensions believes in not over specifying the elastomeric material.  Choosing a cost effective rubber or urethane compound not only saves money at project start up, but keeps on giving for the life of the project.  Continue reading
