1, roller gluing
Melt is supplied to a rotating glue groove on rollers rotate in the groove of the scraper with glue, hot melt adhesive on the melt on COTS scraping uniform product contact rotating rollers uniformly gluing. This glue is mainly used for fabric coating composite plate, glue and so on.
2, foaming glue
In some special applications, in order to get the buffer or shock function, and reduce the use amount of glue, can use a special foaming glue machine in HMPSA melt in mechanically mixed with nitrogen, the formation of HMPSA inflatable. HMPSA on the workpiece through the nozzle will have a mechanical foaming on the foam coating technology has been widely used in the combination of auto parts to replace the traditional rubber gasket.
3, spiral spray
This is one of the most common usage. By controlling external air pressure of the spiral wire glue spray HMPSA from the nozzle with micro spray hole of the spray rules. In this way can greatly reduce the amount of glue glue per unit area. The structure of plastic diapers and sanitary napkins are used spiral glue way glue

4, flat die scraping
This is a common way. Scraping molten HMPSA through heating pipes, evenly distributed in the flow in the die, the die lip from the predetermined film thickness and the width of the mouth is out. Most industrial use of hot-melt pressure-sensitive adhesive tapes and labels are used die scraping glue coating process
5, dot sizing
Dot gluing is an economical and simple process when the two binder is only partially bonded. Dot gluing is commonly used in folding cartons or paperboard
6, strip gluing
Similar to dot gluing, this process can be used in conjunction with two patches only in strips. Common applications include edge of plastic boxes, such as PET curtain boxes, bottle boxes and cosmetic boxes
7, curtain spray
When the object to be coated because of low heat resistance (PE film) or the workpiece surface is not flat, but need to get the glue coating area full, non-contact (left) curtain spray can provide a similar contact die scraping effect.
8, fibrous glue
It's basically a glue spray process and spiral spray is quite similar, but the shape of silk glue spouting is irregular glue quantity per unit area from lower than the spiral spray application market. The most common is the disposable sanitary materials, such as disposable mattress, surgical clothes, hats, shoes and so on.
