There are many manufacturing processes which can help us fulfill our objective. There are two types of methods, spraying as well as Powder coating. All these processes are usually used to coat Teflon pans and can be used to achieve very good results.

Powder coating is the usage of free flowing powders that are applied with conventional electrostatic powder equipment. Both spray guns and fluidized beds can be used. The powder can be applied by using different application voltages and techniques depending on particular equipment. When this technique is used, only one or two coats can be down. After this, the product becomes too insulated for any more coats. If more coats are required, the part must be sprayed hot as it is coming out of the oven from curing the previous coat. Ventilation is required as even if a small amount of PTFE decomposes during the baking processes, the people in the area will ecperience discomfort due to the fumes.

The automatic spray guns are a better option when a large area has to be coated. Since they are automatic, they require great precision and experience. They can be used in a conveyorized system, which will reduce the work and allow the production of more overpacks. Not only that, but the films can be coated more uniformly. The finishing can be fed to the guns through pressure pots which have fluid pressure in the range of about 5 to 8 psi.

Electrostatic spray gun or disc can also be used as well. In this application, the film will be more uniform and we will be able to save 10 to 15 percent of the material because there will be a reduction in the overspray. There are many low prices units available. A high voltage electrostatic charge is applied to the workpieve and the sprayer mechanism. Both powdered and liquid paint materials can be used The overpack is first sprayed with or dipped with paint particles which are

Teflon

...Teflon and Its Applications in Industry 1. Introduction Polytetrafluoroethylene (PTFE) also known as Teflon is a thermoplastic polymer. It is formed by addition polymerization using the monomer tetrafluroethylene (TFE). Teflon is a strong, waxy and non-flammable resin which is used in many applications especially in corrosive industries due to its resistance to chemicals. In addition, it is able to maintain its physical properties over a wide range of temperatures. Teflon was invented by accident by a research chemist named Roy J. Plunkett at DuPont’s Jackson Lab in New Jersey on 6 April 1938. Plunkett and his technician assistant, Jack Rebok, were testing on the chemical reactions of the refrigerant gas TFE, he noticed one of the pressurized cylinders failed to discharge when its valve was opened. Rebok suggested cutting the cylinder open to see what went wrong. They discovered the gas inside the cylinder had solidified into a white powder. Plunkett began to test the properties of the white powder. The white powder was found to be more lubricant than other slippery solids. In addition, it proved to be inert to almost other chemicals and had extremely high melting point at 335°C. Plunkett discovered that the gas had polymerized to become a PTFE resin and thus, invented a way to produce the TFE to PTFE polymerization in the lab. 2. Analysis of Fundamental Structures and Properties PTFE exhibits many useful properties. It is resistant to many chemicals, weather and UV resistance...

...PTFE is used for the non-stick coating on pans and other cooking utensils. It is not reactive because of the strength of the carbon and fluorine bonds so it is often used in containers and pipework to transport reactive and corrosive chemicals. PTFE can also reduce friction, wear and energy consumption of machinery which helps to prolong the machines life and reduce damage to the parts. PTFE is produced by free-radical polymerization of tetrafluoroethylene. The equation for this process is: n F2C=CF2 → 1/n —{ F2C—CF2}n— Tetrafluoroethylene can explosively decompose to tetrafluoromethane and carbon which means special equipment is needed for the polymerization to prevent hot spots that might start of the explosive decomposition. PTFE is also poorly soluble in almost all solvents so the polymerization has to take place as an emulsion in water. An emulsion is a mixture of two or more liquids that are normally immiscible. Properties Density 2200 kg/m3 Melting point 327 °C Thermal expansion 135 • 10−6 K−1 [21] Thermal diffusivity 0.124 mm²/s...

...Classic Case 6 W. L. Gore & Associates, Inc. Frank Shipper Salisbury State University Charles C. Manz Arizona State University To make money and have fun. W. L. Gore On July 26, 1976, Jack Dougherty, a newly minted MBA from the College of William and Mary, dressed in a dark blue suit and bursting with resolve, reported for his first day at W. L. Gore & Associates. He presented himself to Bill Gore, shook hands firmly, looked him in the eye, and said he was ready for anything. What happened next was one thing for which Jack was not ready. Gore replied, “That’s fine, Jack, fine. Why don’t you look around and find something you’d like to do.” Three frustrating weeks later he found that something, dressed in jeans, loading fabric into the mouth of a machine that laminated the company’s patented Gore-Tex membrane to fabric. By 1982, Jack had become responsible for all advertising and marketing in the fabrics group. This story was part of the folklore that was heard over and over about W. L. Gore. By 1991, the process was slightly more structured. New associates took a journey through the business before settling into their own positions, regardless of the position for which they were hired. A new sales associate in the Fabric Division might spend six weeks rotating through different areas before concentrating on sales and marketing. Among other things, he or she might learn how Gore-Tex fabric was made, what it could and could not do, how...

Explain What Happened to the Gore-Tex. Brand After the Patent Expired. What Activity Can Firms Use

...Case study notes This case study explores a very unique organisation: W.L. Gore Associates. It explores the role of organisational management and culture within a very innovative firm, which is responsible for some very well-known products such as the famous Gore-Tex fabric, and yet few people know much about this remarkable organisation. It is operated in a way similar to that of a cooperative such as The John Lewis Partnership in the UK, where the employees are also owners. In addition, the organisation seeks to minimise management with the emphasis on action and creativity. Case study questions 1. Explain what happened to the Gore-Tex brand after the patent expired. What activity can firms use to try to maintain any advantage developed during the patent protection phase? Competitor products emerged (generic versions if you like). To compete, it was necessary to develop the brand. This is something that has not happened. What else could it do? 2. List some of the wide range of products that the Gore-Tex fabric has been applied? All sorts of clothing, shoes, coats, etc. Also, windsurf sales and kite surf sales. What else could it be applied to? 3. It seems that Gore Associates is heavily orientated towards technology. What are some of the dangers of being too heavily focused on technology? Myopic views such as not listening to customer views, too focused on technology. Missing opportunities that may exist, which involve minor changes. Also, marketing mix considerations need to...

...Confirming Pages g Frank Shipper Greg L. Stewart Salisbury University CASE 26 W. L. Gore & Associates: Developing Global Teams to Meet 21st-Century Challenges1 University of Iowa Charles C. Manz University of Massachusetts–Amherst n 2010, W. L. Gore & Associates celebrated its 52nd year in business. Founded in 1958 by Bill and Vieve Gore in the basement of their home, Gore had grown into a global enterprise famous for its high performance fabrics, medical products, and next-generation electronic products, as well as its use of self-empowered teams of employees (called associates at Gore). In its earlier years, the company had endeavored to restrict the size of its different corporate facilities to 200 associates or fewer, a practice that helped keep the number of teams at a given facility to a manageable number and facilitated cross-team coordination. More recently, however, to better cope with the challenges of a global marketplace, increasing numbers of teams were composed of associates in different facilities, sometimes facilities that were spread across three continents; the coordination of team members working in different facilities was enabled by online communication. In 2010, Gore’s products were sold on six continents and used on all seven continents, as well as under the ocean and in space. The company global operations required teams of associates to tightly coordinate their activities in developing, producing, and marketing...

Do you agree with this statement universally? In other words, why couldn’t an established firm test many new and diverse “playing fields” with very small beta tests via prototype new products and services? Or could the established firm do both simultaneously? W.L. Gore is a great start-up firm story Robert. I wonder how they were able to test and use their products in those very different markets without pulling to many resources (mainly R & D) from its original core-product PTFE in the wire & cable industry? It would also be very interesting to find out how they balanced their current commitments to buyers while they tested new applications of their product in different industries, especially in the beginning phases of the business. Gore serves a very diverse customer base with a lot of different needs. My bet is a big key to their success and strategy choice was finding “where not to play” as you stated earlier in your discussion post. I agree beta testing on new products provide the established firm “Where to Play” choices on what can be done to expand the enterprise. But in doing so the established firm still stands to assume some “risk” in product(s) being unsuccessful. In my opinion the firm is “wasting...
