A, EVA hot melt edge definition: 
      EVA based hot melt edge EVA (ethylene - vinyl acetate) based raw material, a tackifying resin, accelerators, fillers, etc., furniture edge for a thermoplastic resin. Typically granular, rod or sheet. After the hot melt adhesive and strong, with liquidity, strong cold, room temperature recovery after physical properties, chemical properties remain basically unchanged. 
Depending on the edge material, edge banding machine, bag stickers different (cover) machine, there is a corresponding matching models use. 
Second, the hot melt adhesive sealing definition: 
    Through automatic linear edge banding machine or manually tune straight edge banding machine, edge banding decorative materials to fit in straight edge or outline the edge of the substrate to play a decorative role and closed. 
Third, the hot melt equipment categories: 
By device type can be divided into manual song straight edge banding machine, edge banding machine for small and medium straight, medium and large automatic linear edge banding machine three. 
Fourth, the operational definition of temperature: 
    Operating temperature, there are two, one for the rubber roller temperature; one for glue roller temperature. Refers to the usual operating temperature generally refers to the temperature of the glue roll. In short, the use of hot melt temperature is the most important, many of the problems are generated and temperature. 
Five operating conditions: 

1, the substrate moisture content 8-12% moisture content is too high, when the sealing, high temperature steam will stick together to produce the film formation shear force, destroy the adhesive force. 

2, the coating weight :180-250g / m2, generally does not overflow glue, no glue or glue line of fine lines is appropriate, otherwise, it will affect the appearance and increase the difficulty of cleaning, also affects the cost. 
3, pressure: pressure 3-5kg/m2, the pressure varies greatly in different adhesion. Pressure is small, the impact of wettability and permeability; pressure, will lead the work shift and excess glue. 

4, the operating temperature settings: 

High temperature plastic: plastic cans glue roller 180 ~ 1900C temperature: 200 ~ 2100C 

The temperature glue: glue pot 150 ~ 1700C temperature glue roll: 160 ~ 1800C 
       Low-temperature glue: glue pot 120 ~ 1400C temperature glue roll: 140 ~ 1500C 

5, the feed speed: the faster the longer the effective combination of the operation, the better the adhesion, the speed is too slow, the shorter the operating time of the effective combination, for adhesion, in order to ensure optimal adhesion effect, sealed under domestic different side of machine, we have different opening hours with suitable models.
