What is Rotational Moulding?

Rotational moulding, also known as rotomoulding, is a manufacturing process used to produce parts and products like tanks, containers, and toys. Rotational moulding involves filling a mould with powdered or granulated plastic and placing the mould in an oven. Heat is applied to the material, causing it to melt and flow into the cavity as the mould rotates around two axes. The finished product is removed from the mould after it has cooled.

What is Plastic Extrusion?

Plastic extrusion is the process of melting plastic and shaping it into a continuous profile. The process begins by heating raw plastic material to the point where it becomes viscous and flowable. The heated plastic is forced through a die, which is a tool that shapes the plastic. The plastic solidifies and takes on the shape of the die as it exits the die.

What is Blow Moulding?

Blow moulding is a method of producing hollow plastic parts such as bottles and containers. The process starts with melting raw plastic material and creating a parison, a tube-like piece of plastic with a hole on one end. The parison is then placed in a mould, and air is blown into the hole with a rod, causing the parison to expand and take the shape of the mould. The plastic is then cooled and solidified before being removed from the mould.
