Selecting the right Plastic material for your product or application can be complicated to say the least.
Here at WKH GROUP we have decades of experience of industrial plastics and their uses, we now have stocks of the most specialised of ranges of plastics.
The following may go some way to get you started:
PLEASE NOTE
If your finished item / component is a stand alone application,
( ie No support from hinges / clasps / braces / guide rails etc )
You must consider-Thermal movement / Bowing and or twisting
