We need to know:
You will typically need a fork lift, operators, resin, secondary finishing equipment such as router, and, of course, a building.
With fixed-arm turret machines, 3- or 4-arm, all the arms index simultaneously. This means heating, cooling, and servicing operations need to be accomplished within same time allotment. The independent-arm machine, with 5 stations, allows one arm to index while the other arms may remain stationary, providing more process flexibility.
The most common types of molds are cast aluminum, fabricated aluminum, fabricated steel, and stainless steel. Other types are available, such as machined and electro-formed.
Polyethylene (LPDE, LLPDE, MDPE,HDPE, XLPE), PVC, EVA, Fluoropolymers, Polypropylene, Nylon, and Polycarbonate.
Yes. There are some highly regarded and very knowledgeable independent consultants that serve the worldwide rotational molding community.
No. Rotational molding is a low- to no-pressure process in which molds are charged with resin, fastened shut, and rotated in two axes at low speeds. Typically, the major axis revolves four times to every one time of the minor axis (4:1). Speeds are slow enough that no centrifugal force is involved.
