As a gauge that can be used to check the hardness of a given material, the durometer can be used in a number of different applications. Here is some information about durometers, and how the devices can be used in a variety of ways. The durometer functions by analyzing a given substance, and then assigning it a number to denote the level of harness and durability. A lower number would indicate a softer nature for the substance, while a higher number would indicate the product is harder and less susceptible to bending or cracking. Along with the number, there is also often a hardness rating, with softer materials being indicated by an “A” and harder being rated as “D”. Thus, a substance that had an overall rating of A30 would be considered not very hard, compared to a substance with a reading of D70. Readings are generally based on checking several spots along the surface of the material and then making a cumulative rating based on the data. While a durometer can technically be used to test the hardness of just about any substance, the main uses of the device are associated with measuring the hardness of rubber or plastic products. Generally, manufactures will have a range of hardness that they consider ideal for the type of goods they produce. For instance, the producer of various types of plastic mats would perhaps want all their products to have a hardness rating of somewhere in the middle range. This method to measure hardness would indicate durability but with a degree of flexibility as part of the final product. Being able to periodically test the production process will help to keep the hardness of the finished products within an acceptable range on the Mohs scale, resulting in products that are of equitable quality to one another. Along with plastic mats, there are also products such as the rubber wheels on roller skates. The rubber is required to be relatively hard, so the wheels will hold up to a lot of wear and tear. On the other hand, a welcome mat made from rubber or plastic would need to be supplier. Using a durometer in the process of measuring hardness during the manufacturing process to ensure the mix of materials results in the level of hardness required can save a company a great deal of time and resources. Regular checks with durometer equipment will quickly identify any deviation from the standards employed by the company.
