Hey all,
i'm renewing my windscreen..keeping the frame but replacing the plastics.I want to keep the bend but make it alot deeper,if you know what i mean?!

Does anyone know any good suppliers in the portsmouth/southampton area that wil bend it too,yes i know with a heat gun it can be bent.. just try pricing this way first?

Many thanks..
 
Worth trying Talking Plastics in Horndean, Sunlight Plastics in Waterlooville in that area.

http://www.talkingplastics.com/
http://www.sunlightplastics.co.uk/

Both have the facility for oven forming.

(Beyond that two posibilities in Colchester. UK Plastics Fabrications and Project Plastics. )

Lexan is just one registered name for polycarbonate. Lexan Excel D is the general purpose grade and is suitable for your application.

SEE HERE for a guide on working with Lexan

Gilbert Curry from whose website I've cribbed the above guide are another possibility.

If the old windscreen can be used as a former then you should have no problems but it will cost many gold bars if they have to make male and female moulds.
 
When we were doing Princess panels, we had to bend the helm panels, these were polycarb.

It is a last resort job, total pain the butt.

We used a hot air gun, but the problem was getting a consistant heat over a area. What you need is a heat panel, so that you have a general heat, avoiding hot spots and burning to the polycarb. May work with a number of hot air guns, but I think it is a pay for job.

[/ QUOTE ] Yes they heat the panel to the correct temperature in a thermostatically controlled oven. The people I got my windows from used the old ones as formers.
 
Not Lexan, but I made a no. of panels out of Perspex using a home made oven to get the 120ºC and forming over a Formica faced mould. Absolute cleanliness was needed, as any specs of dust showed up as dents. Used 10mm material.
What is the temp for Lexan forming? (I know, read the link, but I'm lazy! and the type is small)
