Answered: Clarification on <R7.f> and bending plastics

[Cameron_Schiller]

Hey Karthik:

<R7.f> States:

<R7> Robots are allowed the following additional “non-VEX” components:
f. Non shattering plastic from the following list; polycarbonate, acetel monopolymer (Delrin),
acetal copolymer (Acetron GP), POM (acetal), ABS, PEEK, PET, HDPE, LDPE, Nylon (all
grades), Polypropylene, FEP; as cut from a single 12" x 24" sheet up to 0.070" thick.
i. Plastic can be mechanically altered by cutting, drilling or bending etc., but it cannot be
chemically treated, melted or cast. Teams may heat the polycarbonate to aid in bending.

Can you please clarify on “chemically treated, melted or cast.”

Would vacuum forming be an example of melting or casting a plastic, or does that fall under “heating the polycarbonate to aid in bending”

Further more, could you form a plastic by placing it around a mold and manually applying heat to it in order to bend it to the mold’s shape?

Cast is defined by as: “an object made by shaping molten metal or similar material in a mold.”

Thanks!
