Hi there, Ive seen a method of plastic products being made

Customer Question

Hi there,
I've seen a method of plastic products being made where a steel mould of an object is heated and then filled with a plastic powder for a couple of seconds (time depend on how thick plastic part must be). It's then cooled and de moulded. inner surface (where plastic powder's is not melted) is then closed by flame.
Could you advice me on what this method is called and where I can obtain more info on this method please.
thank you kindly,

Kobus

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 again.

I am not aware of that process. I am going to opt out of this question which will allow other experts to chime in.

Hold on.

Hi Kobus,

 

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!

Hi Expert,


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.

I understand. I hope the company's website link I provided will help get you the information you're looking for.

Thanks again. P.J.
