Audi Quattro, an ’81 Saturn metallic car with period spot lights (in reality the quad lights weren’t up to much) and a glass sun roof!! The ‘VRP’ plate is sequential with the other Audi U.K. press cars
Glass Industry Terms – Everything You’ve Always Wanted to Know About Glass But Were Afraid to Ask What is free? Free is an industry designation for the color applied around the perimeter of the car glass parts. One of the most important ingredients in free is a glass ceramic particle that melts into the glass surface, making it a very durable and scratch-resistant surface.Why is free (color) on the glass? Frit serves two roles on the glass. First, it is a cosmetic function that is used to hide interior and nipple details. Early model vehicles used widescreen to hide what would otherwise be vulnerable areas. As lists became smaller to the point of non-existence on several current models, the fritus had a greater role in covering unfinished parts of the vehicle. Secondly, free UV inhibition of urethane glue inhibits. While the freezer does not completely block the UV rays from passing through the glass, it greatly reduces the UV light transmission. Most urethanes are not UV-stable. If the urethane is left exposed to sunlight for long periods of time, it turns yellow and twists critically. The occurrence of leisure time extends the life of the urethane adhesive system.How many types of free are there? There are hundreds of types of frits developed for automotive glass applications. The most common glass fryers we use are black, gray and white, although other colors are available. Free pastes are developed to work in combination with the treatment requirements needed for a certain part. Each paste is designed for specific oven and temperature parameters used to manufacture parts at a manufacturing site. It is not uncommon for a glass production plant to work with a dozen different frites pasta.How to apply freely to the glass? Freely applied to the glass using a silk screen method. It is very similar to the method used for silk screen T-shirts. An image of the free design is developed for the glass in curved or curved form. Then the image is unopened and flattened. A silk screen is made to allow the frit to pass through openings in the screen. The openings correspond to the final design image. The fries are a thick paste that is put on the screen. Squeegees are used to push the fry through the screen openings and on the glass. Freely applied to the glass while in flat position before being processed through the oven. The oven helps to harden the fryer and melt it to the glass surface. Each part with every other design has a unique silk screen. Silk screens are constantly kept throughout life. Due to the fragile properties of the screen, they will wear out and usually need to be restored throughout the lifetime of some in the production.What is batch glass? Batch is a reference period for glass that identifies part of the manufacturing process. The raw glass constituents are properly proportioned and mixed in batches for delivery to the oven. Although glass is made in a continuous process that runs 24 hours a day, every day of the year, the raw materials are added.
