EMI Seals Gaskets Free Design

Complimentary Seal and Gaskets Design Service

Sealing and shielding solutions are complicated systems whose operation and service life are determined by a number of variables. These include interactions between particular system components and the various application running circumstances.

Client collaboration is at the heart of EMI Seals & Gaskets as a company and as part of our service, we offer complimentary seal and gasket design and consultation. We offer this and work this way to ensure the specific requirements of our clients and potential clients are met.

EMI Seals and Gaskets Ltd is UKAS ISO 9001:2015, ISO 14001:2015, and ISO45001:2018 design certified; our industry professional staff captures customer requirements and converts them into specific designs.

Significance of complementary design service

Sometimes what is requested, what has been used previously, or what at first appears to be the obvious choice, is not always the optimum solution. Or perhaps no obvious solution presents itself. We choose to understand the application before making any recommendation on design and material.

DetectElast Elastomers

DetectElast Elastomers

If you are involved in production or production equipment for the Food, Beverage, Pharma/Bio & Life Science Industries industry you will be acutely aware of the necessary Health & Safety legislation that governs the use of Seals, Gaskets, O Rings, and similar items. 

Certifications – EU1935: 2004, FDA 21 and NSF / ANSI 51

EMI Seals & Gaskets Ltd offer a wide range of sealing products that are certified to meet these requirements including EU1935: 2004 and FDA 21 CFR part 177 Section 2600 Allowable Substances. We also have our own NSF / ANSI 51 certification for Seals and Gaskets that come into direct contact with food on equipment and follow the HACCP (Hazard Analysis and Critical Control Point) principles and application guidelines.

C Wrap – Environmental seal and Shielding seal Combination

Birth of C-Wrap

If you make or are involved in Cabinets, Enclosures or Doors do you find that you have to make two or even three different configurations, depending on whether your client wants an environmental seal, a shielded seal or a combination of both.

Traditionally you might have fitted a sponge strip, or you use a form in place gasket for the environmental seal or finger stock for shielding or a combination of sponge strip and finger stock or maybe a knitted wire and sponge arrangement top meet the combination of both.

Problem with traditional sealing methods:

The trouble with this is time, planning and money, having to alter your principal design every time a client wants something slightly different, and having to hold stock of different seals and gaskets and expensive shielding materials.

What happens if the client then wants a V-0 fire rating or an ATEx/IECEx approval or a DEF-STAN grade or they need multiple gland plates or access plate covers that need Sealing and Shielding?

One company has a simple, cost effective, easily fitted and highly adaptable solution that can fulfil all your requirements and more.

  • V-0 fire rating – no problem,
  • ATEx/IECEx approval – no problem or
  • DEF-STAN grade – no problem.

Not All Rubbers Created Equal - EMI Seals and Gaskets

Not all rubbers are created equal

Why Test houses want full disclosure of elastomer contents and why you should too!

Commercial Quality Rubber and Regrind, Do you really know what you’re buying?

When you buy rubber sheet or specify Rubber parts you usually say “I want X rubber in Y hardness” but do you question your supplier as to where your rubber was made and what’s its composition. Unless you specify a specific rubber grade like BS2751 or BS2752 you will be quoted and given Commercial Quality Grade Rubber and that’s where your problems could be starting, Do You Really Know What You Are Buying?

Toxic smoke inhalation – the Silent Killer

Importance of UL94 V0 certification for Seals, Gaskets, and Mouldings

Were you aware that people are much more likely to die from smoke than burns during a fire?

Toxic fumes obstruct eyesight, irritate the eyes and lungs, and makes it difficult to breathe. Mental capacity loss, dizziness, fear, and finally unconsciousness leading to death are the end consequences of inhaling toxic smoke. The London Kings Cross fire incident in 1987 is one such example, the official findings stated that, “A jet of flame roared into the ticket hall, which quickly filled with toxic smoke so that even many of those who escaped the flames were overcome and died” (1), all because of toxic smoke inhalation.  Statistics reveal that 41% of fire-related deaths in the UK (2) were caused when people were overpowered by gas, smoke, or poisonous fumes.

EMI Seals and Gaskets Oscillating Knife Cutter

New Oscillating Knife Cutter

New Oscillating Knife Cutter Adds Greater Versatility

EMI Seals and Gaskets Ltd is pleased to announce that we have just taken delivery of our new oscillating knife cutter to add to our machinery stable.

It is the perfect complement to our waterjet and hydraulic press die-cut machines.

Our state-of-the-art continuous feed oscillating knife cutter has a 3m x 2m bed, a range of interchangeable heads including Stanley knife, drag knife, creasing knife, and kiss cutting knife, is fitted with a digital camera and is able to cut materials up to 50mm thick.

It repeatedly cuts with exacting precision, to within +/- 0.1mm on many materials.

Engineered to cut hard materials such as compressed non-asbestos, steel inserted graphite, hard rubber, cross-linked PE foams, composites, plastics, equally as well as softer more delicate materials such as foams, sponges, paper, and graphite. The continuous feed belt makes it ideal for long runs as well as lower quantity runs and special one offs.

Elastomer Compression

Optimum Elastomer Gasket Compression

The question of what is the optimum compression for an elastomer gasket, seal or O-ring is one that we are regularly asked. It is one that we also like to be asked as merely torquing any elastomer seal up as hard as can be is not the answer (this will just break down the cell structure and remove the properties for which it was chosen), and we always advise the use of compression stops, where possible, to limit torque.

Of course there is no one size fits all answer as the optimum interference is dependent upon the application, design and the material.

However we recommend working within the window of 25% min – 50% max, with the general sweet spot being 35% compression of the materials thickness. This applies to both solid and sponge elastomers.

These percentages are confirmed by SGS Baseefa Test House, and are also stated on our IECEx Hazaradous Area report for our pre-approved silicone.
