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

Pedals – MDI Products in Action

April 13, 2018

To the left is an example of a custom molded foot pedal used in large excavation equipment. The chemically-bonded urethane pad exhibits wear resistance, making it look better and last longer despite highly abrasive environments.

 

  • Material Compound: Most pedals are made with 80 Durometer Shore “D” Black Pentathane®. Hardness, as applied to elastomers, is defined as the relative resistance of a surface to indention by an indenter of specified dimension under a specified load. The most commonly used measuring instrument is a durometer. Numerical hardness values are derived from the depth of penetration. The harder the sample, the further it will push back the indenter point and the higher the readings. On the durometer A scale, 0 is very soft, and 100 is very hard. Values are usually read immediately after firm contact has been established. The hardness range of elastomers is so broad that a single durometer cannot indicate practical measurable differences of hardness. For this reason durometers are available in more than one scale model, (eg., A and D scale durometers). The A scale durometer is widely used throughout the rubber industry. The durometer D model, which has a stiffer spring and a more pointed indenter, is used to measure the hardness of hard rubbers.
  • Special characteristics: abrasion and cracking resistance helps keep the pedal looking brand new for years to come.

MDI Chemist Explains Updates in Polyurethane Industry

July 31, 2015

Written By: Tony Lukas, Chemist Molded Dimensions Inc

screen-shot-2015-07-31-at-9-33-35-amPolyurethane 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.
