T4 Quad Headlight Project.
Latest prototype headlight mounting bracket, just a quick video on how I created a back-up of my resin tooling plug. Material used was 0.75mm PETG, machine is my Formech 508DT.
Next time I'll try and keep the finished part in the frame ! Sorry about that !
Enjoy ; )

Love the "Tap test" ..... Such a professional looking machine and the forming itself is so fast! Tight to the tool. VERY cool Turk. - Slimjim
Hi Jim, Many thanks for the kind comments my friend , very much appreciated. The 'Tap Test' also known as the 'Finger Nail' test, that I'm sure you already know is to test just how pliable the plastic sheet is, as your finger nail would leave as small indentation in the surface of the plastic when it's ready to be formed. This vacuum forming test also shows just how well the design of the tooling plug works ( self releasing ), forming plastics of 0.75mm and 1.0mm is pretty straight forward, but as you've clearly seen in the forum photos, things become very complicated when using materials such as 3mm ABS ! www.vwt4forum.co.uk/showthread.php?t=249064&page=279 Thanks TURK
Does the master mold have to be metal. Can it be any other material?
Says in the description that the plug ( mould ) is made of resin Buddy. The industry use aluminium plugs for thermoforming, but anything that will resist temperatures of about 120°C will work ............... so you could make moulds out of MDF if you like. The resin I use is 'Vac-Cast Epoxy resin' as it very stable. Hope that helps Buddy ; ) TURK
