Rotational moulding, also known as rotomolding, is a manufacturing process used to create large hollow plastic products. For a Calf Shed, this technique would involve using a heated hollow mold that is filled with a charge or shot weight of plastic. It is then slowly rotated (usually around two perpendicular axes), causing the softened material to disperse and stick to the walls of the mold. Read More

Rotational plastic products can be applied in industries such as transportation, traffic safety facilities, entertainment, river and waterway dredging, construction, water treatment, medicine and food, electronics, chemicals, aquaculture, textile printing and dyeing. Read More

Rotomolding as a process dates back to 1855 with R. Peters of Britain using biaxial rotation and heat to create metal artillery shells and other hollow vessels.

Peters of Britain using biaxial rotation and heat to create metal artillery shells and other hollow vessels. Rotomolding was introduced in the plastics world in 1950 as a way to manufacturer doll heads. In the 1960’s an indirect high velocity air system replaced the direct gas jets as a way to heat the products allowing for the manufacturing of large containers from low-density polyethylene. In the 1980’s other plastics like polycarbonate, polyester, and nylon were introduced to rotational molding allowing for the production of fuel tanks and industrial moldings. Read More

Most beef producers wean around seven months of age, according to John B. Hall, Ph.D., PAS, a University of Idaho professor and extension beef specialist. However, there is more to consider than age.“The time of weaning should be matched to the producer’s forage availability and post-weaning goals,” he said. “So, we need to be flexible on timing.” Read More
