Cutting only straight lines and being a fairly slow approach compared to other finishing methods, guillotining can be expensive for projects with larger, more complex quantities.[5]
As easy as it would make all of our lives, vacuum pumps are far from being “one size fits allâ€. Not only do you have the size to consider when choosing a vacuum pump, but more importantly type.
Always wear the proper personal protective equipment (PPE) when operating a vacuum pump. Your facility has rules and regulations in place for handling all types of mechanical and electrical equipment. Vacuum pumps possess electrical and moving mechanical components that can cause serious injury without the proper PPE.
For instance, let’s take a moment to look at how a rotary screw air compressor generally operates. The basic process involves two large screws (one male, one female) rotating side by side. The screws pull air in at one end, rotate together to compress the air between each other, and finally push the compressed air out of the other end.
Relatively deep parts can be formed if the formable sheet is mechanically or pneumatically stretched prior to bringing it into contact with the mold surface and applying the vacuum.[1]
Process liquids require a different type of separator to assure liquids don’t make their way into your pump. Minor liquid damage can cause couplings to break, contaminate the oil, and cause rust or corrosion of internal pump components. Moderate liquid damage can cause electrical drive motor failures due to excessive loading, broken vanes in rotary vane pumps, damage to exhaust valves, deformed internal pump components from hydraulic pressure, bearing failure from the contaminated lubricant, or sludge buildup. Severe water damage can permanently destroy the pumping module if it attempts to compress a liquid.
This process can be used to form plastic into permanent objects such as turnpike signs and protective covers. Normally draft angles are present in the design of the mold (a recommended minimum of 3°) to ease removal of the formed plastic part from the mold.

Once a vacuum forming has been created out of a sheet of plastic, a finishing operation will be needed in most cases to turn it into a usable product. Common vacuum forming finishing methods include:
Many failures during operation can be traced back to improper maintenance in some way or another. Have you been cleaning and changing your pump’s inlet filtration elements as advised by the pump’s provider?

Look at that! We’re already narrowing your search down by eliminating options simply based on the operating environment. Here are some other questions to keep in mind when searching for the right pump for you…
For the most part, the technology used to compress air is the exact same technology used in industrial vacuums. “Industrial†is a keyword here. We aren’t talking about your mom’s standard carpet vacuum. Quincy vacuums reside in a range higher than your typical household vacuum called the “Rough Vacuum Rangeâ€. Most industrial vacuums operate within this range. Medium, High, and Ultra-High ranges deal with a much different market involving more rigorous applications like simulating space vacuum levels, scientific research, producing semi-conductors, and so on.
Wood patterns are a common material to vacuum form as it is relatively inexpensive and allows the customer to make changes to the design easily. The number of samples that one is able to get from any pattern depends on the size of the part and the thickness of the material. Once the specifications of the part have been met, the pattern is then used to create a ceramic composite mold, or cast aluminum mold for regular production.
