Envision Plastics Expert Announces Part Six in the Series: How to Design Plastic Enclosures Using NMR Technology.
White Bear Lake, MN (PRWEB) July 16, 2013 -- The last installment in this “How to Design a Plastic Enclosure” series described the NMR Technology CNC Milling process Envision Plastics uses to create custom plastic electronic enclosures. This installment will move on to detailing the forming process.
After the individual part components are milled, they are deburred as necessary and go through a sawing application that puts a 90 degree miter in the flat component to essentially remove material. This miter serves as a consistent bend line that will “close” to a sharp inside 90 degree angle after the part is formed (the outer angle is also 90 degrees, but has a nice form radius equivalent to the material thickness).
The bending process itself is not complicated. The flat part component is placed on a granite bed and heated with an element which aligns with the newly sawed bend line. After a specific interval of time (depending on plastic type and thickness), a portion of the bed rotates up to the desired bend angle which is most often 90 degrees to create a plastic enclosure. Then the part sets for a few seconds in this position and is released to reveal a formed part component.
All necessary plastic enclosure components will be formed in this manner and then staged for the next step in the process - Bonding. In the next installment, we’ll describe this solvent bonding process in depth.
