(1) EVA foam manufacturer lamination time is too long or too high

EVA foam manufacturer laminate was applied to maintain the pressure on the assembly time. Vacuum time, pressing time, and EVA foam manufacturer EVA lamination time is the sum of the curing time. Under the pressure of the airbag begin the assembly process is internal residual gas discharge process, and apply some pressure components, so that after curing EVA film molecular structure is more compact, with better performance if EVA foam manufacturer to master without lamination component is good bubble phenomenon possible.

(2) the presence of a foreign body, the wetting angle greater than 90 degrees

As workers in the work and actions are not standardized careless in the production process is adhered on a component or components of a foreign body when you sprinkle tin soldering presence, resulting in lip angle greater than 90 °, in EVA foam manufacturer lamination process because there is a large foreign cause bubbles generated.

(3) heating plate temperature is uneven, so that the local Advance Curing

(4) EVA foam manufacturer lamination time is too long or too high, decomposition of the organic peroxide, to produce oxygen gas

(7) EVA foam manufacturer EVA lamination temperature exceeds the limit will produce dense small bubbles. (Figure)

Measures:

1 should focus 6S management, particularly in the laminate this procedure, try to avoid falling into foreign matter

(2) to strengthen workers' skills training, awareness-raising, appear to have spread all do, but off the phenomenon of tin processing.
