The word DUROMETER comes from DURUS meaning hard and METER loosely meaning measuring instrument. In practical use today, durometer can be used to describe the instrument used to measure hardness, as well as the material’s hardness. Durometer is measured by the depth of an indentation into a test specimen under a standardized force. Softer material will allow a deeper indentation. Continue reading

Polyurethane suppliers and processors are continually looking to develop new materials and applications to take advantage of the unique properties of urethane. One advantage that urethane has over rubber is much higher abrasion resistance. This has historically been particularly true as the hardness reaches Shore 80A and above. Although materials of softer hardness have long been available, the physical properties and abrasion resistance has not been a good as rubber in the 50A-70A range. New developments are allowing for both polyether and polyester based materials that are great improvements over currently available urethanes and even better than natural rubber and SBR. Typical applications for these types of materials would be in systems with heavy flow of particulate containing liquids or slurries. Continue reading

Molded Dimensions was founded in 1956 as a custom molder of cast polyurethane, Pentathane®, and molded rubber goods. The business cut its teeth in the early days of our development and growth modeling our business management procedures based on the Balanced Scorecard Approach to Business Management. This approach was originated by Drs. Robert Kaplan and David Norton as a performance measurement framework that added non-financial performance measures to the traditional financial performance measures utilized by businesses.

This, in turn, draws great customers to our business. Great customers provide for stable, profitable business growth benefitting our employee owners. Continue reading
There are two types of abrasion – sliding and impingement. Sliding is the passing of an adjacent surface across the rubber surface. Impingement is wearing of the rubber exemplified by sand particles hitting the surface. Most wear in actual service occurs as a combination of both sliding and impingement.
When sliding, localized friction forces can impose high energy levels on the rubber. Abrasion and wear takes place when the rubber cannot withstand these forces.
What’s In an ESOP?
Written by: Mike Katz, President
In late 2000, when I learned about employee stock ownership plans (ESOPs), I became intrigued at the notion of shared ownership and what it could mean for an organization’s health. Imagine if each person who works at a company truly thinks and acts as an owner would. An organization where the notion of “other people’s money” does not exist because it is everyone’s money. Continue reading

If you record “How It’s Made”, have passion for hands-on continuous improvement, and thrive working on high functioning teams, you likely understand that some people are simply destined to work in manufacturing. And some of them are women, like me. I am Linda Katz, proud CEO and owner of Molded Dimensions, Inc. Despite my gender, I have always felt supported in my quest to work in engineering and business.

Cast polyurethane, formulated to have a balance of characteristics associated with premium materials, is a great solution in demanding roller applications. In addition to its superior material characteristics, urethane can be molded and finished easily.
• Superior abrasion resistance
In applications, such as manufacturing diapers, forming food product bags, or cash counting systems, urethane offers the abrasion resistance necessary to reduce wear, thereby reducing the frequency of worn roller replacement. Continue reading
A lot of what we do here at Molded Dimensions Inc. is technical, precise, and extremely detailed. This blog post breaks down compression and shape factor for molded rubber and urethane mechanical components in a way that can be understood by engineers and lay persons. These basic principles described here are useful when applied by designers throughout the part design process. Continue reading
