Hi Steve, no I'm not referring to injection moulding. The method I witnessed was made of a 1 mm thick mild steel plate mould that was filled with plastic pellets grounded to a finer powder. The steel mould is then heated with gas burners at +- 45 deg C for two minutes to melt the plastic in to a form. then the access powder tipped out the mould. The mould is then cooled down and form de moulded. The inside of the form where the powder was is then heated with a gas flame to give a glossy finish.
Hi Steve, could you manage to obtain any info on the plastic forming I asked you about ?
Rotational molding is the name for the method you are interested in.
This website describes different methods and has contact information for a company that can likely get you any further information you may need.
I hope this helps. Thanks for using JA!
No, I'm quite familiar with rotational moulding and this method I'm referring to is not rotational moulding.
It works on the same principal but the mould is stationary.
Hi P.J., Thanks for your reply, I could not find the link of the company you think may help me. Please send it to me on the answering page.
appreciate your time,
