Rotational molding uses high-temperature and low- to no-pressure to form and produce usually hollow items from plastic resins; typically polyethylene. Product molds filled with the resins are heated and then rotated slowly along both horizontal and vertical axes to disperse the molten plastic through the mold in the desired form and thickness, including varying thicknesses when required. Rotation continues during cooling to maintain the finished products integrity.
Our electronic control systems monitor the molding process and adjust rotational velocity and the rate of heating and cooling to ensure each piece is produced to the required specification.
We will custom build the molds used in your process to specifications you provide or design them from scratch to meet your needs.
Molds are fabricated or cast from:
- Stainless steel
- Carbon steel
Additional product features to take into consideration:
- Double Wall
- Metal Inserts
- Flame Polishing
