CNC machining, which stands for Computer Numerical Control, is a manufacturing process in which pre-programmed computer software dictates the movement of tools and machinery.
The process can be used to control a range of complex machinery, from grinders and lathes to mills and CNC routers.
But in our case, Gallagher is utilizing this process to cut both custom and standard seal profiles for our customers.
Material certifications, seal geometry and even seal color must also be factored in to allow for maximized seal life, minimized risk and reduced total cost of ownership for both the seal and the rotating equipment.
The most challenging operational environments for sealing mixers, agitators and pumps are often found in the food and pharmaceutical industries. When designing, selecting, or implementing a dynamic seal into operation in the food and pharma space, it is crucial to consider all the physical challenges the seal may face to ensure sealing success. Further, material certifications, seal geometry, and even seal color must also be factored in to allow for maximized seal life, minimized risk and reduced total cost of ownership for both the seal and the rotating equipment.
In this article, we will highlight some of the common environments found within these industries, discuss how the operating conditions affect seal design and selection, and finally, share some

This is the last of a three-part article series about silicone processing operations for life science applications. In the first article, we shared the versatility and unique qualities of silicone as the medical device material of choice. In part two, we covered the different methods of manufacture for medical silicone components and devices. This article discusses how design for manufacturability (DFM) aids in selecting the right manufacturing process for your medical device application.
As a full-service solutions provider, Parker CSS Division’s Life Science Business Unit provides design for manufacturability services and offers highly responsive assembly and testing of medical instrumentation — from simple electromechanical devices t
Freudenberg Sealing Technologies announced they developed special, innovative seals that are in high demand for solar energy facilities.
The groove profile in the customer‘s plastic application proved to be a challenge for the seal’s design. Available tolerances and specific installation spaces had to be taken into account. “We were looking for the right material as we proceeded with calculations and simulations,” recalled Ralf Schmid, Senior Vice President, Special Sealing Division at Freudenberg Sealing Technologies. In the end, the company’s expertise in engineering and materials won the day – all the more because the sealing rings were designed for an operating life of 30 years. “We developed the optimal product at the optimal cost, eliminating the customer’s concerns relating to a c
Seals are small components that have a big function. At their most essential purpose, they keep fluid in and debris out. Failure to do this can lead to costly machine destruction, and even endanger the lives of people working around these machines. Preventing seal failure is very important on many different levels.
Many factors can cause a seal failure. Being aware of these factors will help you in preventing an avoidable failure. Seals are under constant pressure because of the liquid or gas being contained. Typically, the seals in pipes or machinery have some type of matter within transferred at high velocities. This is a huge part of what they were designed to do, but too much or too little pressure could wear down the seals.
In addition, extreme temperatures can cause the seal to become brittle. A mixture of extreme temperatures and pressure is a recipe for cracking and leaking. Also, debris can contaminate the integrity of the seal. Even
When engineers at Hoover Dam determined that the original cast iron lantern rings built into some of its turbines needed to be replaced, they were looking for a solution to help them overcome the corrosion issues they experienced with the cast iron.
The maintenance team also faced another challenge. The Colorado River serves as a water source for the Hoover Dam hydropower station, and the water in this area is commonly referred to as “hard water” due to its high mineral content, specifically high levels of calcium and magnesium ions. Aluminium lantern rings that were first tried as a replacement, were corroded by chemical reactions with the minerals in the water.
KLINGER® Quantum is the first fiber reinforced gasket material in the world that is exclusively HNBR-bound. Together with a unique production process developed specifically for the purpose, this material can be used at higher temperatures and with a much wider range of media than any other fiber reinforced gasket material that is currently available.
This material is suitable for use in oils, water, steam, gases, salt solutions, fuels, alcohols, weak organic and inorganic acids, hydrocarbons, lubricants and refrigerants. KLINGER Quantum is manufactured with a high-quality fiber and filler compound reinforced with a high temperature resistant HNBR matrix.

Heavy duty equipment moves industry forward in all climates, from the sunny Caribbean to icy Greenland. Effective, reliable sealing is what allows hydraulic systems in heavy duty equipment to do work, no matter the temperature. Reliable sealing solutions allow cylinders on dump tr
In appliances used for water purification and carbonated water, the valve of a carbon dioxide cartridge and the pressure-reducing valve on the device itself must be joined with a secure seal. Now, Freudenberg Sealing Technologies has developed a patented, high-performance polyurethane seal for a customer that has a specific geometry that not only accommodates different valve dimensions on the various gas cartridges, but also offers high impermeability under long-lasting pressure.
