This means paying attention to factors that influence the price of steel, or are otherwise likely to cause disruption or fluctuation in the market. Like other commodities, metal prices are always shifting in ways that are critical to the life of our business and those in adjacent industries.
Due to their inherent physical properties and characteristics, rubber materials are not capable of supporting the same level of dimensional tolerances that can be achieved with some other materials such as steel or hard plastics.
Dimensional tolerances are an important factor to consider and specify when sourcing or buying cut or molded parts, including cut parts manufactured from solid sheet rubbers or cellular materials such as sponges and foams.
Tolerance designations for cut or molded parts relate to the variability that normally occurs when producing parts from solid or cellular rubbers. In this blog, we examine some of the factors that can affect the tolerances of cut or molded rubber parts, and which in turn determine the final dimensions of a finished part.
Factors affecting the tolerances of cut or molded rubber parts: Numerous factors can cause variation in the dimensions of a cut part. Material age and cure time, storage and processing temperature, and the pressure imposed on the material as it is being cut can all affect the final dimensions.
In addition, secondary operations, such as buffing and finishing, may affect the final dimensions as well as the reproducibility of those dimensions within a batch of parts. At CRG, we use GFA Gasket Fabricators Association best practices in our production processes to assure that the tolerances agreed to with a customer are achieved when cutting solid rubber parts.
When cutting parts from cellular rubber materials, such as open or closed cell sponges and foams, we follow the guidelines and tolerance tables published in the ARPM Association for Rubber Products Manufacturers, Inc. In addition to these best practices for tolerancing, all production at CRG takes place under controlled conditions designed to assure quality, following the processes and procedures implemented under our ISO Because of the variability inherent in both solid and cellular rubber materials, and the processes used to cut parts from these materials, it is unrealistic to expect the same precision of tolerances that are achievable when machining solid metals such as steel or aluminum.
When specifying desired tolerances in a cut rubber part, design engineers and buyers should take care to refer to tolerance tables, such as those published by the ARPM, which are followed by reputable part manufacturers.
These include the following: In molding rubber parts, there may be difference between the mold dimensions and the completed part.
This difference can be caused by material shrinkage as the part cools and by shrinkage of the base compound used to produce the part. While the amount of shrinkage can be minimized, it cannot be eliminated entirely.
These variations can result in dimensional differences of the completed part. As with cut parts, secondary operations, such as flash removal, can result in dimensional variation in the finished part.
Subjecting finished parts to stresses, such as those caused by moving or packing, can distort the part and result in dimensional differences. Environmental and storage conditions. Rubber changes in dimensions as temperature and humidity changes.
For molded parts that are used in critical applications that require precise dimensioning, the temperature and humidity under which a part is to be measured should be specified. For customers seeking molded rubber parts, CRG follows the tolerancing guidelines and requirements contained in ISO The relevant test methods necessary for the establishment of compliance with ISO The tolerances specified in ISO CRG supplies a variety of cut or molded rubber parts for a wide range of industrial and automotive applications.
These include gaskets and seals, parts for isolation, damping and load bearing, connectors, bumpers, caps and grommets, and many more. We carry a wide range of performance materials which allows to produce cut or molded parts for almost any application.

With the rise of steel prices in the market, the price of diesel generator sets is also rising, especially in some places, electricity supply is short, some areas have been limited electricity, which makes the price of diesel generator set rise again.
This presentation was presented by me to explain the various factors affecting industries by taking the case study of Tata Steel, Gujarat and Punjab. There are different factors affecting the efficiency of a supply chain and the attempt of this paper is to find the most important elements in agile supply chain.
