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.
Die cutting is an all-inclusive term for the process of using a die to cut sheets or rolls of a variety of materials, such as foils, laminates, gasket materials, polyesters, polycarbonates, and more.
Valves are indispensable components in the hygienically sensitive systems used in the food, beverage and pharmaceutical industries. Until now, there were no high-pressure valves available for food-product contact applications that conformed to 3-A® standards. These global hygiene standards address the design and manufacturing of components that come into contact with food.
Bardiani Valvole approached Gallagher's partner, Freudenberg Sealing Technologies, for help in developing a solution to tap into its material expertise. As a result of joint cooperation, Freudenberg engineers developed a main rod seal that was both 3-A® compliant and capable of handling high-pressure of up to 2175 psi (150 bar) that the customer’s valve required. The main rod seal incorporates proven Freudenberg technology with advanced component design in an entirely new combination that is also compatible with other industrial high-pressure valves.
The 3-A® compliant main rod seal combines a sealing lip, manufactured from EPDM 302 or Fluoroprene® XP 43, with a backup ring made of PTFE. Freudenberg’s product engineers were inspired by the design of a proven shaft seal and an O-ring with a backup ring. In order to meet development and cost deadlines, the team initially produced one-off prototypes to share with Bardiani Valvole using the unique capabilities of Freudenberg Xpress®, a fast turnaround, high-quality manufacturing service that can generate custom seals in as little as a day. It offers machined seals made of original materials and original profiles for prototypes, spare parts or economical small series.
By eliminating the need to set up manufacturing tooling to produce sample parts, this results in considerable cost and time advantages for the customer. Thanks to special turning and milling techniques, individual designs can be tuned to exact specifications. The tailor-made sealing solution for the new high-pressure valve could also be produced economically in an extremely short time. The Freudenberg Xpress® Service is represented at numerous Freudenberg sites worldwide, enabling rapid delivery of spare parts, for example.
The seal’s design is free of dead space and prevents residue infiltration from process and cleaning media. It is hygienic, easier to clean, and compliant with all relevant material specifications for food, beverage, and pharmaceutical industry applications. Both materials used have very good thermal resistance and excellent mechanical properties. They also meet the demanding requirements for use in Cleaning in Place and Sterilization in Place (CIP/SIP) processes.
As the COVID-19 pandemic continues to impact communities around the world, Gore is working hard to identify ways in which they can apply their materials science expertise and production capabilities to help during this time of need.
Several initiatives are underway that bring together the knowledge, skills and capabilities from across Gore.
As an immediate and initial response to the personal protective equipment (PPE) shortage, Gore rapidly engineered prototype reusable mask covers to supplement clinicians’ primary face masks.
The effort went from a product concept to prototypes in less than one week. Gore currently has prototypes being evaluated at a limited number of U.S. facilities in COVID-19 outbreak hot spots.
Additionally, by providing their customers and other manufacturing companies with Gore's highly specialized component materials, they can use them to produce a variety of finished PPE items, such as:
It is through these collaborations with those who have the technical capabilities and production capacity needed to produce the finished goods in volume that together, Gore and its partners truly are improving life.
Gore has even donated medical supplies and protective gear to healthcare workers in the communities in which their facilities are stationed. They've also extended a hand to provide engineering and prototyping support to address other urgent equipment needs at local hospitals.
Precision Associates, Inc. has ramped up its production of several essential rubber components for ventilator manufacturer Ventec Life Systems. Ventec recently announced plans to partner with GM to increase the output of these crucial units in response to the COVID-19 pandemic.
Critical patients suffering from the virus have difficulty breathing and require ventilator assistance for life support. GM is now transforming one of its factories to begin assembling ventilators for Ventec in early April.
Rubber Compound Data sheets usually display a number of physical properties as recorded from standard test methods. Among the most common are three measured on the Tensometer:
The Tensometer stretches a specimen, or dumbbell, cut from a sheet of rubber, until it breaks. During the test, the force required and length of the gauged section are measured continuously. These measurements are used to calculate the various results, which considers the actual dimensions of the test specimen.
While Tensile Strength and Ultimate
