Miniature pneumatic parts made from custom rubber molding are powering a growing number of new medical devices, laboratory equipment and other devices that employ fluid power in small packages. These important components are responsible for controlling the flow and pressure of air and gases in such uses as ventilators, oxygen compressors and gas detectors. Rubber molding is often used to create seals and valves in miniature pneumatic parts that are required to function well in challenging environments, time after time. For custom rubber molding of miniature pneumatics parts, success depends upon four operations: Material selection and custom compounding Precision tooling for tight tolerances Finishing and cleaning operations Inspection and quality control Miniature pneumatic applications using custom rubber molding are growing...

Four Considerations in Designing Molded Rubber Parts Versus Molded Plastic Parts

Posted by flexan
07/30/18 03:00 PM
With the lines blurring between the use of thermoset elastomers or rubber and thermoplastic elastomers in product design, what distinguishes rubber from plastic in the context of micro-precision, molded parts? Although product designers may think that a part design using thermoset elastomers is interchangeable with plastic, the chemical properties and molding characteristics of the two are very different, requiring parts designed to suit the material. With applications requiring smaller parts with difficult configurations growing in demand, new product designers must address the challenges of part design and material specification early on in the development process. Four considerations in choosing molded rubber parts or plastic The function of the part and its application The part’s operating environment Aesthetic considerations Production costs...

Answers to Eight FAQs about Molded Rubber for OEMs

Posted by flexan
07/30/18 02:59 PM
Manufacturers in a wide variety of industries rely on molded rubber parts for high performance in their products. With rubber being only one of many materials used in developing a new product, OEM engineers and purchasing managers pose similar questions about how elastomers work and which rubber material is right for their application. Following are answers to eight questions that OEMs often ask.   Q.  What is a thermoset elastomer? A.  An elastomer is a polymer with viscoelasticity, which simultaneously exhibits the properties of a very thick fluid and a flexible solid. Thermoset elastomers are a class of polymers that are cured
 by cross linking molecular chains during the molding process, which requires the right amount of pressure and temperature...
