Step-by-step construction of rotationally moulded parts: a physical approach

Introduction Rotational moulding is now used to manufacture a wide variety of hollow parts, ranging from small products of a few hundred millilitres to industrial tanks holding tens of thousands of litres. Despite this diversity of applications, the quality of the resulting parts remains heavily dependent on the way the polymer is distributed […]

What are the influential characteristics of polymers in rotational moulding?

During rotational moulding, the intrinsic characteristics of the polymer play a decisive role in the success of the process, the final quality of the part and the stability of the thermal cycle. Rotational moulding is based on the progressive heating of a polymer powder in a biaxially rotating mould, without significant external pressure. In this context, the material must [...]
