Ultrasonic Lace Machine For Vacuum Bag

Ultrasonic Lace Machine For Vacuum Bag – Cheersonic

What’s cacuum bag? Vacuum bagging uses atmospheric pressure as a clamp to hold laminate plies together. The laminate is sealed within an airtight envelope. The envelope may be an airtight mold on one side and an airtight bag on the other. When the bag is sealed, pressure on the outside and inside of this envelope is equal to atmospheric pressure: approximately 29 inches of mercury (Hg), or 14.7 psi. As a vacuum pump evacuates air from this envelope, the air pressure inside is reduced while air pressure outside of the envelope remains at 14.7 psi. Atmospheric pressure forces together with the sides of the envelope and everything within the envelope, putting equal and even pressure over the surface of the envelope. The pressure differential between the inside and outside of the envelope determines the amount of clamping force on the laminate. Theoretically, the maximum possible pressure that can be exerted on the laminate, if it were possible to achieve a perfect vacuum and remove all of the air from the envelope, is one atmosphere, or 14.7 psi. A realistic pressure differential (clamping pressure) will be 12–25 inches of mercury (6–12.5 psi).

Ultrasonic cacuum bag welding means the cohesive bonding of thermoplastic fabrics through internal friction, heating and fusion of the material. The ultrasonic sewing technology is a modern, innovative and economic alternative and complementary to conventional sewing technology. Workpiece is held between the sonotrode and the anvil wheel and welded continuously under pressure. Ultrasonic energy provides savings, efficiency and clean production opportunities in the area where it is used. The ultrasonic sewing technology is widely used in producing Dust Collection Bags. Flat-layed goods, three-dimensional structures, hard-to-reach small parts, closing or closed mouldings – an optimal free arm is available for every application.

Cheersonic has focused on the technologies of ultrasonics and automations for more than 20 years, and supply a series of standard ultrasonic sewing machine as well as bespoke ultrasonic sewing solutions for different industries, such as automotive, hygiene and medical, filtration, industrial safety and so on.
