Heating temperature: The infrared filament-type cathode tool and hot plate tool both can be up to 550-600℃. But the heating time is totally different. Infrared welding machine heat preservation 350℃ to 600℃(preheating product)time is only 1s. But hot plate welding machine heat 0℃ to 600℃(preheating product), Time: more than 45mins.
The heating way of a normal hot plate using heating tubes can’t meet the quick heating-up effect, which will greatly reduce the machine’s usage rate.
Heating method: IR filament only heats the welding ribs area, while heating tubes heat the whole hot plate.
when heating up to upper than 550℃, it needs a very high requirement of hot plate material, heating tubes, and other accessories of a normal hot plate, and it’s very difficult to control large deformation of the hot plate under high temperatures.
Heating distance: when heating, between IR filament and product welding ribs, there is a distance.
Due to the hot plate’s function being to heat the product welding ribs surface, the hot plate can’t touch the welding ribs, if the hot plate touches the welding ribs, then the welding ribs surface will be damaged before closing together.
Product welding ribs surface temperature: both methods are above 200 ℃, To minimize closing dust, welding ribs surface should heat up to a molten state.
Heat conduction: IR filament only conducts heat partly. The whole hot plate tool conducts heat.
The whole normal hot plate conducts heat inside of the hot plate welding machine, this will cause the inner machine temperature will be very high, and the machine’s internal components to be protected.
