Moulded Diaphragm are required for a functional operation role. As such they should be moulded with that criteria. They are not the same as general component mouldings. The tool designs are different to attain the equal balance through the diaphragm and the materials also have to be designed to attain the repeatability.
Meadex moulds approx 400 to 500,000 Diaphragm seals per year in many different sizes for a variety of applications. Diaphragms are used for switch activation in Automotive / medical or building valves. There application is very diverse, and the design and materials have to reflect that.
Moulding diaphragms that are FDA and WRAS approved compounds and other technical compounds. All will be supplied with data sheet and full traceability if required. Meadex offer Diaphragms in FKM, Silicones , EPDM and Neoprene. We also offer clean room manufacture.
Meadex Precision Rubber Mouldings Ltd. has over thirty years experience specialising in the manufacture of precision rubber components for over 30 years.
By definition, rubber diaphragms are flexible seals that prevent unwanted transmission of substances between two places. These substances can be liquids, gasses or solutions. They are characteristically tough and dynamic and essential in many flow control applications. We provide full production capabilities from prototype and short run quantities through large production runs. Meadex Precision Rubber Mouldings Ltd takes pride in its ability to consistently produce precision custom rubber diaphragms guaranteed to meet your most stringent requirements and function perfectly within your application.
We offer Material compound selection for your engineering requirements.
Homogeneous Rubber Diaphragms
Meadex Precision Rubber Mouldings Ltd. provides diaphragms produced entirely of rubber. These homogeneous rubber diaphragms are used in very low-pressure applications when the strength of a fabric reinforced diaphragm is not required. Homogeneous rubber diaphragms offer similar functional advantages as fabric reinforced diaphragms and tend to be more economical for our customers not requiring a sturdy construction.
Fabric Reinforced Rubber Diaphragms
Meadex Precision Rubber Mouldings Ltd. provides a variety of custom moulded fabric reinforced rubber diaphragms designed and engineered for specific industry applications, including:
• Pneumatic actuators
• Pumps and control valves.
• Gas controls
• Valve diaphragms
• Air compressors
The fabric reinforcement ensures stability and consistent functional performance over the required range of temperature and pressure conditions, whilst providing greater sensitivity and improved sealing performance than typically possible with alternative fabric reinforced materials. The application also requires very tight dimensional tolerances, with thickness being controlled to less than the ISO 3302-1 Class M1 allowance
Our years of experience in the gasket manufacturing industry has proven that certain applications demand that a rubber elastomer layer must be very flexible and tough in order to withstand repeated flexing over a long lifetime. It is required that each and every custom moulded rubber diaphragm be able to handle mandatory operating temperatures and also be resistant to any chemicals, fluids or gases it may come in contact with. The construction of fabric reinforced rubber diaphragms is achievable using special reinforcement materials including:
• Polyester (Dacron)
• Polyamide (Nylon, High Strength)
Rubber Diaphragm Industry Applications
Rubber diaphragms and fabric reinforced rubber diaphragms are critical to the operation of equipment and systems in the industrial, automotive, aerospace, oil, gas, medical instrumentation, and pump and valve industries.
If a dependable and accurate response to a hydraulic or pneumatic pressure change is needed then almost certainly a diaphragm seal is required. Meadex Precision Rubber Mouldings Ltd. is experienced in engineering and manufacturing solutions for diaphragm applications including:
• Pneumatic diaphragm pumps
• High pressure diaphragm pumps
• Pressure gauges
• Vacuum pumps
• Air compressors
• Actuators, pneumatic actuators
• Thermal actuators
• Control valves.
• Automotive Carburettors
• Gas Control & Valve Equipment
• L.P.G. & Methane Gas Actuators & Regulators
• Diesel & other fuel pumps
• Gas & Fuel metering equipment
Diaphragms are widely used in chemical industries, food processing, pharmaceutical, beverages, etc. The main function of the diaphragms is used to protect the process fluids from the pressure sensor.
We have also developed special thin wall diaphragms for actuator applications; these diaphragms have critical sealing requirements and are manufactured within a tolerance of (or ±0.015 mm).
