The manufacturing and installation of specialty seals must be handled in a certain way to ensure their quality and longevity.
The following guidelines and/or rules are the basics for regulating the engineering of seals to ensure top performance.
Performance vs Knowing Your Seals
The performance of your machine(s) depend on the quality of your seal and the conditions they succeed in. They can directly affect how well or how poorly your machines function. By extending the life and care of your seals, you can, in turn, extend the life of your equipment.

For the sealing expert, the world of sealing terminology comes naturally.
But for those who don't live and breathe seals every day, the list of terms can quickly become quite daunting.
Thanks to our partners at Minnesota Rubber, this blog post will examine Part 2 of Sealing Terminology - the terms you may come across when looking for fluid sealing products.
Hardness – A measurement of the resistance to penetration of a rubber sample by an indenter. High values indicate harder materials while low values indicate softer materials. (See also durometer, IRHD, and Shore A
HDPE – High-density polyethylene

Abrasion – Surface wear caused by relative motion between contacting objects
Abrasion Resistance – The ability of a rubber compound to resist surface wearing by mechanical action
ABS – Acrylonitrile-butadiene-styrene
Accelerator – A chemical compound that speeds up the vulcanization of natural or synthetic rubbers
Adhering Flash – Extremely thin flash (usually less than 0.002′ thick) that adheres to the finished part during molding or deflashing processes

Failure is not an option in the most demanding sealing applications. Valves continually strain the capabilities of sealing solutions, and elastomer solutions are often not enough. The unparalleled reliability of high-performance metallic seals from our partners at Technetics can help excel in the face of these challenging scenarios.
In these extreme environments, high-performance metallic seals combine state-of-the-art engineering with advanced materials design to deliver a product that exceeds expectations and stands up to the rigors of these applications.
Why Use High-Performance Metallic Seals?
Traditional sealing methods, such as elastomers or graphite seals, present limitations when extreme environments come into play. Under the tremendous workload of valves in these applications, they can lose tightness or deform, presenting distinct challenges.

Fluids play a critical role in sustaining life. Keeping animals and humans hydrated and helping plants grow are obvious ways. Less obvious ways include moving cargo around the world and keeping equipment operating (hydraulic oils, coolants, engine oils, etc.). All these applications require seals of some sort ranging from public water systems to hydraulic pumps. What happens when these fluids become aggressive? People typically think of acids as being an aggressive media, but for many fluoroelastomers, bases are more aggressive presenting severe challenges.
Using material science and technology, Parker has created a new class of Base Resistant (fluoro) Elastomer (BRE) compounds.

Using GORE® Low Friction Film, a tissue-thin coating material made from graphite-filled expanded PTFE (ePTFE), enables a new level of performance in dynamic elastomer seals: Lower friction. Longer life. Better tightness.
GORE Low Friction Film – an innovative, tissue-thin coating material for dynamic elastomer seals – creates a permanent mechanical connection with the elastomer during the molding process.
Made from graphite-filled ePTFE (expanded polytetrafluoroethylene), this new solution opens up new opportunities and potentials in design, performance and application of dynamic seals. In automotive applications, it reduces friction and improves wear-resistance while maintaining excellent elasticity and sealability. Quite simply, this material is made for designing the future of mobility.

Valves for the process industry must meet particularly high demands in terms of hygienic design, industry-specific approvals and resistance to CIP/SIP media. This also applies to the seals. Gallagher Fluid Seals' partner, Freudenberg Sealing Technologies, has developed a new series of high-performance seals for butterfly valves. This was done in cooperation with their French customer Definox.

In this brief blog, we will go over the high-level aspects regarding injection molding - what it is, the benefits, and how it generally works. Give us a shout if you think it might be a great fit for your next project or application!
What is injection molding?
Injection molding is a way to manufacture and produce parts in large quantities. It is often used in production scenarios where the exact same part is being produced over and over again in the thousands.
The main advantage of using injection molding is the ability to scale production in enormous portions, resulting in price per unit becoming much lower. While the initial investment may come with some added costs, it will eventually for itself over time and ultimately result in profit.
