Injection molding is an efficient process for producing polycarbonate parts in nearly any shape for nearly any industry.
During the process, thermoplastic pellets are fed into a heated barrel, mixed and forced into a mold at high pressure. The heated thermoplastic cools and hardens, forming a part that takes the shape of the mold.
Some key advantages of this process include:
·Fast cycle time
·Ability to produce large quantities of parts
·Ability to accommodate a variety of part sizes
·Excellent part-to-part repeatability
·Creation of parts with tight tolerances
Polycarbonate can be readily machined and Rebling is able to provide a full range of secondary machining operations, such as turning, drilling, tapping and grinding, as well as ultrasonic insertion, ultrasonic welding, pad printing and assembly. When designing parts that are to be fastened, it is recommended that self-tapping vs. thread forming screws be used. For repeated assembly and disassembly, threaded metal inserts should be used. Ultrasonically installed insert is preferred over a molded-in insert as the knurls on a molded-in insert can cause notch effects on the plastic, reducing its strength.
