Hot plate welding uses thermal energy to melt the welding zone through heat
conduction. It is a cost-effective process and large batch sizes are possible.
However, the process is time consuming; typical cycle times being 10 to 60
seconds. This results in a strong bond that can bear heavy mechanical loads.
The molten polymer is exposed to air during the process, which may reduce the
weld strength due to oxidation of the polymer.
