Pedals – MDI Products in Action

Posted on April 13, 2018 by The Molded Dimensions Team

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.


Durometer. Do You Know What It Is?

Posted on August 14, 2015 by Nick Cusatis

screen-shot-2015-08-14-at-10-46-28-amThe 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
