How choosing the correct gasket reduces risks

Health and Safety across any industry are vital, especially so in industrial facilities and settings.  Why?  Because harmful leaks and emissions must be avoided at all costs to avoid serious accidents or injury to your teams and property.  That’s why having the right...

How to tighten your bolts perfectly

How to tighten your bolts and which tools you should use to achieve the perfect seal is not as seamless and straightforward as we would like. Various factors come into play in these situations, such as bolt grade, size, and even application type.  Tightening torques...

Static and Dynamic o rings

A range of factors and application dynamics come into play when choosing a particular type of o ring.  You need to understand the type of seal exert you require, the dimensions, and even compounds.  Due to the nature of an o ring and its overall design, o rings use...

Gasket Sealants

Fortunately, no one gasket suits a range of applications, but rather we have a multitude of gasket sealants available to meet various specifications and requirements.  Ultimately, sealants are used to effectively ensure gasket seals.  Helping to extend a gasket's life...

Types of industrial gasket material

Different industry sectors will use different types of gaskets and different types of gasket materials.   And of course!  Different industrial gasket materials will be much better suited to some industrial processes and applications compared to others.  As different...

Keeping a close eye on the gaskets your applications use

Gaskets are vital elements to any piping system and application that requires creating the perfect seal in order to prevent leaks.  This is the main role of a gasket, to provide a good seal, with some gasket materials sealing better than others in certain...

O Ring Colour Identification

O rings come in various colours, and it's important to understand what these colours indicate as the o rings you choose will affect your overall process application.  Ultimately, different o ring colours are used to help differentiate between different materials. ...

Spiral Wound Gasket Compressibility and Pressure Ratings

In order to form a reliable seal, spiral wound gaskets do require a certain degree of pressure.   The applied pressure allows the gasket to be compressed tightly between the mating surfaces preventing any leaks from occurring.  Factors such as operating temperature...

Elastomeric Compounds

What is elastomer?  Elastomeric compounds are rubber seals produced using natural rubbers or manufactured by the chemicals industry.  Elastomeric sealing compounds consist of between 50-60% rubber; the remainder of the compound consists of fillers,...

Is there such a thing as the right flange gasket?

We cannot stress enough how important gaskets and seals can be. Gaskets are vital for an application's reliability and integrity, and trust us when we say, choosing the right gasket now can help you avoid costly issues in the future.  Taking a closer look at pipe...

Gasket manufacturing process explained

The process of manufacturing a gasketSpecialist Sealing Products have been providing high-quality gaskets to customers throughout the UK for many years. We pride ourselves in the range of gaskets we have available, suitable for a variety of applications across a range of industries. 

Rubber gaskets are indeed the perfect solution to, in their simplest form, fill the gap between two parts. Helping to provide a tight seal that prevents leaks, helps to reduce noise, or can act as a support mount. 

Rubber gaskets are so versatile that they can be used in any business operating in any sector needed for any application. It is primarily used in oil and gas, food processing, pharmaceutical, water, and petrochemical industries. 

Manufacturing rubber gaskets – The Process 

Cutting and punching play a big part in the manufacturing process of gaskets. Producing a range of different products in a range of volumes, all dependant on specific requirements. 

Ideally, you need to work with a manufacturing process that provides the best solution for you, and one that is ultimately fit for purpose.

Most common production techniques 

Punching 

Gasket punching is one of the most traditional methods in the manufacturing process. Gasket punching involves a bent steel strip that can be moulded into the desired shape and then fed through a sheet of the gasket, followed by a cutting board. Gasket punching involves a sharp blade being pressed into the steel to pierce through the sheet material, cleanly and with ease. The shape inside the cutter is then the finished gasket. 

Originally, gasket punching was widely used in the shoe industry; however, due to its many benefits, the process of punching is used to manufacturer a much wider range of gaskets for a variety of industries. 

Punching is the best manufacturing method if you’re looking for consistently sized gaskets that require large volumes to be produced. 

Cutting 

Gasket cutting can often be preferred to gasket punching because a number of different product characteristics come into play that cutting can work with effectively and efficiently. 

Types of cutting involve: 

Kiss cutting – which is used to support the handling of smaller punched parts. 

Water jetting – which involves a high pressure of jet water being blown through a sheet of material to cut it. This particular manufacturing method allows hard or soft, cellular, or solid materials to be cut quickly and in a wide range of shapes. All done without deformation that is often found on other punching processes. This process is also good if you’re looking for a quick run. (Note: materials that absorb water are not suitable for this process). 

Laser cutting – similar to water jetting, you’re simply just using a laser instead. The benefits are also similar, but with lasers, you can experience a flammability problem. 

Hand cutting – ideal for much larger and more bespoke gaskets. A traditional manufacturing process but still extremely useful. Hand marking out shapes and then using knives and saddle punches to create more bespoke gaskets. 

Strip cutting – which uses a rotary knife to convert the strip material into the end product. Using a rotating knife, this process cuts long sheets of material into strips using a circular rotation. The distance between each blade is then set, determined by what is being produced. 

Finishing touches 

It’s important to ensure that the products manufactured are also trimmed, finished, and packed to a very high standard. 

The product still is not 100% complete as soon as it comes off the production line, it needs to be finished, by sealing experts. 

SSP provides a range of gaskets to suit your individual needs. Give us a call to ask one of our sealing experts about the right gasket for you. 

Gasket manufacturers SSP have the flexibility, as well as the tools, machinery, and processes to offer customers a wide range of punched and cut gaskets. 

Working with a range of volumes to support several industries, we’re proud of our robust manufacturing processes.
