Unique and effective EMI gaskets and seals

          The Electro Magnetic Inference shielding seals have proved its immense worth in the electronic industries. Today, huge challenge is faced when it comes to designing and manufacturing of electronic devices or equipments for the consumer or business markets. With increase in demand and need for perfect devices complexities have increased as these devices are more inclined to electromagnetic interference. With advent of Electromagnetic shielding or EMI these complexities have been resolved but has not so far proved its worth. These shields usually implemented in a design isolate component or section of a device from one another and therefore need of these gaskets are vital.

EMI shielding seals or the Electro Magnetic Inference shielding seals are highly reliable in performance and ensure effective productivity. Incorporated between the shield and mating surface of the devices, they do wonders. While meeting compliances of EMI requirements these gaskets are of great benefit. Cost effective in nature they can be used as basic method of saving money while manufacturing a system. These unique and effective gaskets not only maximize EMI or RFI shielding but it is also helpful in reducing the number of fasteners or screws which comply the requirements. These conductive gaskets serve as an environmental seal to protect dust and moisture.
EMI shielding seals are best for controlling undesired electromagnetic energy and radio frequency interference from disrupting or radiating from electronic devices. Their availability in different shapes, sizes and configurations make them highly demandable.

The Electro Magnetic Interference shielded gaskets and seals come in a wide range with their volume resistance in order to achieve the desired shielding effectiveness. Products are available as non-hardening caulking compounds, silicone or vinyl based sheets as well as conductive adhesives and coatings.

Darcoid Nor-Cal Seal is into supplying world class EMI shielding Gaskets and Seals, O-Rings, Molded Rubber Parts, EMI or RFI Shielding products like Adhesives, Sealants, Conductive Compounds, Conductive Elastomer Gaskets, Conductive Tapes and laminates, Conductive Grounding Tabs, Metal EMI products, O-Rings and D-Rings, Shielded Windows, Shielded EMI Vents, Thermal Grease & Gap fillers, Wave Guides, Wire Mesh Gaskets and many more.

High purity PTFE seals

High purity plastic valves and PTFE seals are made from PTFE, PVDF and other high purity plastics. These types of valves are produced by specialty plastic fabricator manufacturers for use in severe and critical service applications for the Pharmaceutical, Defense, Alternate Energy, Semiconductor, Medical and Chemical industries, to remotely control fluid flow. Since these products, including PTFE seals, are most often utilized in a corrosive laboratory environment or clean room automation environment, the high purity plastics of construction ensure the best results against corrosion and their chemical resistances offers long life within the application. Custom fluid control products made from polytetrafluoroethylene (PTFE) and other industrial plastics can be found in a wide variety of specifications to meet the many possible applications and can often be tailor-made to a customer's particular requirements.

PTFE seals are used to remotely control fluid flow. Their use is becoming increasingly popular in a wide variety of industrial applications thanks to their relative simplistic nature and affordable installation cost. With an enormous range of high purity plastic valves on the market, factories and plants throughout the industrial sector are easily able to find the right valve that meets the exact specifications of their intended use.

PTFE seals and valves are electrically actuated to either their open or closed position. The valve components work by allowing or restricting liquid flow depending on whether or not they are subject to an electrical current. The trigger device is normally an electromagnet coil which activates when fed an electric current, attracting a plunger or other valve stem component to changing the state of the mechanical device, this in turn allows or prevents liquid flow. When the electromagnet is deactivated, the plunger is returned to its original position typically by means of a return spring.

Darcoid’s selection of products is the broadest offering in the industry for hydraulic and PTFE sealing systems. Darcoid Nor-Cal Seals is an enterprise that is globally renowned as an endeavor that is into delivering top quality accessories for diverse machinery. Darcoid Nor-Cal seal is a global platform in the industry of mechanical equipment related parts.

Customized quad rings

Quad rings like all other O-rings are used for sealing. These are excellent for preventing various kinds of fluids/liquids or gas loss. These O-rings has the potential to function both as a static as well as a dynamic seal. As a static seal, it is immovable and is used simply for containing pressure or maintaining a vacuum. On the other hand as a dynamic seal it has reciprocating capabilities. They are doughnut shaped and are generally molded from an elastometer compounds like synthetic or natural rubber. Among its various application areas are mechanical setups where they prevent flow of air and fluid through sealing. They are usually fixed to cavities or: grooves to achieve all kinds of resolutions in sealing as high as 1000 PSI. In fact, these O-rings can endure temperatures ranging from -200 degrees Celsius to +250+ degrees Celsius.

The quad rings are the most preferred options for engineers across the world for all their sealing needs. This is because these are dependable, safe and long-lasting. Today, these are used in industry sectors ranging from automotive to fluid power to semiconductor processing. You can find quad rings in passenger cars, construction equipment, heavy duty trucks, refrigeration and air conditioning components, commercial and military aircraft, pharmaceuticals, oil and natural gas rigs, kitchen and bath fixtures, surgical instruments, fuel handling equipment and drug delivery devices. Apart from the standard sizes, quad rings also come in different customized varieties as per their inner diameter: its cross-section diameter: material composition and hardness. And the only factor that is responsible for this is the compression which determines the O-ring cross section diameter. It is to be mentioned here that the inner diameter of O-ring should be similar to the inner diameter of the groove, so that it can get stretch and stick to the groove.

With the huge demand for quad rings, Parker has also come up with a novel idea of developing customized O-rings of nearly infinite size range as per the requirements of individual clients. Most of the authorized distributors of the quality accessories have this option of taking orders from various consumers. However, it is completely the prerogative of the customer to determine whether such data and specifications are suitable and sufficient for a particular application. The customer should also be able to foresee its applicability in components or systems. Darcoid Nor-Cal Seals supply the best parker O-rings. This globally recognized endeavor that is into supply of gaskets, sealants and sealing solutions, Darcoid Nor-Cal Seals is an excellent source for superior grade O-rings and gaskets. From the beginning to the final stage of production these suppliers ensure you lend supreme material consistency to your needs.
