EMKA custom gaskets

While many installations of sealing gasket profiles fit the pattern of a common design, e.g. enclosure door seals, we can readily see from a quick glance at typical applications that often new sections are needed to fit new equipment designs. While being generally of a common concept, e.g. a “P” profile form, the detail design and execution required to perform correctly in-situ may be significantly different from a standard production item. Custom-made products include: frames, rings, lengths, butyl, mastic, flock coating, notching, gluing, slip coating etc.

Custom gaskets therefore fall into three categories:

  1. Standard sections with second operations, e.g. ventilation holes to release internal pressure from the tubular section or assembled and vulcanised frames where spliced joints ensure that the resilience and dynamic properties of the profile are maintained throughout the joint, thus creating an endless seal.
  2. Integral adaptations, e.g. by adhering a section to a spine so creating a “new” profile from two existing components.
  3. A complete new design with new tooling incorporating new choices of materials and design criteria.

Gasket manufacturers typically produce a “standard range” of commonly used sizes and styles which they carry in stock as extruded material – and in addition will accumulate over time a stock of tooling which covers all the other sections they have ever made – and from which it is possible to make new gasket. The number of available sections in this way can easily number many hundreds, but even so new sizes and designs are frequently needed to suit specialist applications eg. sealing sunroofs, doors, classic vehicles, buses, Teleco cabinets, or with particular features: dual hardness profiles, wire inserts, ventilated profiles, flame retardant, Nitrile (resistant to oil).

Some common materials used in rubber extrusion include EPDM, SBR, (CR – Neoprene), Silicone, (NBR – Nitrile), and (NR – Natural rubber). Read our whitepaper here for further info…..

Common concerns re materials for custom sections include:

– Comparative features of common rubber/synthetic rubber materials

– Comparative vulcanising properties of NR and other SR’s

– Fluid immersion national and international test methods

– Brittleness temperature of some Engineering Elastomers

– Compression set

– Determination of hardness

– Heat resistance and aging

– Tensile properties

– Specific gravity and density

So customers who think they may require a custom profile gasket are encouraged to contact a specialist manufacturer such as the team at EMKA who can assist with the detail specification and hand hold the process.

EMKA specialist gasket profiles for enclosures, cabinets, vehicles, HVAC

EMKA (UK) Ltd and EMKA Profiles Ltd, are looking forward to demonstrating our UK manufactured products at the PPMA Exhibition on 1st – 3rd October at the NEC on stand number G96.

EMKA Profiles Ltd specialise in the manufacture of spring steel inserted profiles which are a combination of edge protector with bonded sponge. These rubber profiles are a co-extrusion of solid and sponge rubber, which allows them a dual role as they cover sharp or unfinished edges and also offer a sealing function.

A major focus of the stand will be on Birmingham-made extruded sealing profiles for specialist enclosures, cabinets, vehicles, HVACR and other industrial sealing purposes. These standard and custom gasket sections – self-adhesive, channel mounted or edge mounted with a spring spine as with typical “P” sections – form an important part of equipping electrical housings, specialist vehicles and other industrial applications.

Here at EMKA (UK) Ltd we offer these UK-made standard profiles from stock in Coventry along with many others from the EMKA production family also from stock or available to order.

Profiles in EPDM, neoprene, PVC, black nitrate and natural rubber cover traditional expanded closed cell (self-adhesive) foam, through wiping blade and bubble or P type sections, with self-grip (clip-on), channel fixing and window type (with expansion insert), to more complex multi-functional and custom designs, perhaps with fillers or flocked weather strips and supported sections with internal or flange structural support.

This range includes EPDM, NBR, CR, PVC and silicone, as well as fire protection and hygiene specifications. Specialist considerations regarding shore hardness, tensile strength, recoil elasticity, abrasion resistance and climatic/chemical resistance can also be advised upon and allowed for in custom production.

Under our slogan of “everything but the enclosure” EMKA (UK) will also be showing  many locks, latches, hinges, swinghandles and related hardware especially suited to the industrial applications in the industries of food, beverage, pharmaceuticals, household products and toiletries, building materials and supplies, pet care, micro-brewery and distilleries, FMCG, as well as contract packers and more. For example, our stainless-steel program for food and pharmaceutical industries, and ranges for HVACR and for railway/transport applications. At the top end of the access management/protective hardware range comes the EMKA/Digitus Biometric locking program for protection and management of data centre storage devices in racks and cabinets.

Invisible, comfortable, without handle – a flat design style of locking handle is the trend for mobile homes and many other applications. As an innovation driver, EMKA have developed a new, electronic and invisible electronic ePush Lock for exactly this situation.

EMKA ePush-Lock invisible locking system

EMKA ePush-Lock mechanism The user simply opens and closes the door or flap by pressing the outside flap. The flap opens automatically without further manual intervention and fits perfectly into the exterior design of any caravan, specialist vehicle or office cabinet – without visible cut outs or corresponding dirt traps. The lock is screwed and mounted behind the flap, so there is no need to interrupt the outer seal and the integrated electronics enable integration into the central locking system. An emergency opening is also incorporated.

We are delighted to offer specialist gasket profile sections in flame retardant, low smoke, low tox materials which are primarily aimed at railway applications such as mobile units, coaches, rolling stock, enclosures, station installations and related equipment operating in elevated risk areas.

Especially for customers of the railway industry, our engineers have developed a product range with fire-protection tested or fire-protection capable locks, hinges and gasketing made of fire prevention checked material. It complies with the special requirements of the sector and is designed to meet the relevant standards such as DIN EN 45545-2 “Railway applications – Fire protection on railway vehicles”. In our in-house Technology Centre both standard and customer-specific solutions for railway vehicles are designed.

Of particular interest are likely to be custom sections including vulcanised frames for immediate installation on doors, panels, inspection windows and similar. These include EPDM gaskets fire prevention tested to DIN 5510-2 NF F 16-101/-102 and silicone sections tested to DIN 5510-2 NF F 16-101/-102 UNI CEI 11170 CEN / TS 45545-2* (*replaced by DIN EN 45545-2).
