Roto Moulding Comparison to Other Methods

Comparison of Rotational Plastic Moulding with Other Plasitics Manufacturing Processes

Plastic Blow Moulding:

Rotational moulding is a good alternative to blow moulding where wall thickness is to be anywhere between 3mm and 10mm. This is due to controlled wall thickness and durable outside edges. There is also the ability to add reinforcing ribs into the part during production.
With plastic blow moulding, tooling costs are also very high and not economical unless hundreds of thousands of items are being produced.

Plastic Injection Mouldings:
As with plastic blow moulding, the tooling costs for the plastic injection moulding can be a hundred thoudand dollars or more per item.

Plastic Vacuum Forming:
The main problem with plastics vacuum forming is inconsistent thickness occurring at product bends.

Plastic Thermoforming:
This is an alternative to plastic blow moulding where products of wall thicknesses over 3mm in quantities between 250 to 3000 are needed. The disadvantages of plastic thermoforming are:
a) The high cost of production
b) Inconsistency of wall thickness on bends
