Traditionally used in heavy industries to design prototypes and produce thousands of models, vacuum forming machine and molds have become increasingly popular with individuals wanting to produce their own works.
Identification:According to Formech International, a producer of vacuum forming machine, molds can range from simple carved wooden pieces to complicated aluminum forms that can be used to create items such as car dashboards or airline cockpit controls. Materials:Plaster and wood molds are used for low temperature plastics requiring few parts, while jobs requiring higher temperature plastics and industrial production numbers use aluminum based resins or aluminum molds. Realistically, Plastic materials are easy to manufacture and create with few costs. Most plastic products are created by using special molds, which the take the liquid plastic and construct it into the desired shape. One mold is used multiple times, making the process predictable and easy. Plastic are easier to fabricate than metal components and require less energy and time for the process. Workers don’t have to be as skilled as metal workers, which makes it possible to use workers with little experience.
almost anything can be used as a mold so long as it can withstand the temperatures of the plastic being used, according to Professor Ted Selker of the Massachusetts Institute of Technology (see Resources). In the years following the war, Regina’s competitors out-performed them, and Regina experienced dwindling profits. They attempted to broaden their sales base by adding other cleaning products to their repertoire. When that failed to increase profits, an investment group purchased majority interest in Regina.
Process:The process for using a vacuum forming mold is fairly simple. The mold is put in place on the machine first, on an apparatus that can be raised or lowered. A thermoplastic sheet is inserted into the machine and then heated. The mold is raised from below into the hot plastic, and the plastic molds around it. The vacuum then draws all of the air out of the plastic and sets it to the mold’s shape. After setting, air is pumped back in to separate the mold from the plastic. The investment group introduced the Regina Steamer, and the Regina Housekeeper and profits improved. Unfortunately, the investment group experienced management problems, and sold their rights to Regina. In 2000, the Royal Corporation purchased the rights to Regina, but sell the vacuums using the Home Depot brand name.
Types:There are two types of molds used by vacuum forming machine: male (positive) and female (negative). Male form molds project upward toward the plastic sheet, while female forms molds project downward. The top surface of the mold is what comes into contact with the plastic and is therefore better finished, and that is the determinant for using a male or female mold. Benefits:vacuum forming machine can be used in many industries. They are used by companies in the fields of aeronautics, agriculture, automotive, construction, computers, design, electronics, and many more. They are versatile and easy to produce.
