Detailed Description
35 Khz Ultrasonic Sealing Equipment Rotary Process For Ultrasonic Fabric / Film Bonding
Descripersion
Ultrasonic bonding is the process of using high-frequency compression/relaxation of materials against specially designed anvil patterns that cause them to heat at the molecular level and melt.
A systematic experimental and numerical combined study of the thermomechanical
bonding mechanisms in the ultrasonic welding (UW) process was conducted. A fully coupled thermomechanical finite element model has been built to fully understand the evolution and coupling between the in-process thermomechanical variables. The severe, localized, plastic deformation at the bond region is believed to be the major phenomenon for bond formation in ultrasonic welding. The influences of substrate dimensions on bond formation were studied and explained with an analytical vibration model. The formation of banded and cyclic stress-strain maxima in the substrate was found to be caused by superposition of vibrations. A push-pin type, combined experimental and numerical, method has been developed, validated, and applied to quantitatively determine the bond strength of UW parts. The best bond strength produced using the set of process parameters in this study was 75% of the ultimate tensile strength of the base material (Al3003-H18). Effects of UW parameters (normal pressure, vibration amplitude, and travel velocity) on bond strength have been characterized. Due to the weak vertical bond strength of UW parts, the pressurized post-weld heat treatment (PWHT) approach is originally proposed to improve the bond strength. The results show that the modified bond strength, up to 96% of the strength of the base material, can be achieved under the optimum parameters of 2.5 MPa pressure, 450 C temperature, and 1.5 h time.
This process enables the materials to flow around the shapes of the anvil and adhere to each other and to other materials that are in the web matrix. It is only a part of the ultrasonic sewing machine.
It need be assembled on the ulltrasonic sewing machine, and drive by an other rotary horn.
Characteristics:
1. Seamming,trimming and embossing without glue, thread or other consumables
2. More faster and cost effective than traditional sewing machine and adhesive ways
3. Eliminates fraying or unraveling of bonded edges and seams
4. Multifunctional and thousands of designs available
5. Requires minimum training and maintenance
6. Super strong ultrasonic power meets the needs of different fabric thickness
The ultrasonic rotary process (welding wheel and horn rotating on a parallel axis), allows a perfect sliding of the fabric to get:
Waterproof welding
Cut and weld assembly
Regular welding

Application An ultrasonic sewing machine is versatile and easy to use in order to seam, cut, slit, trim, tack, emboss, or to cut and seal at the same time. The process used by every ultrasonic sewing machine is fast, simple and efficient. It can seal up to 80 meters per minute without the need for threads nor needles.
It is indeed a flexible technology. Due to the adaptability of its design, it is possible to mount the sewing machine on a workbench or to install it into semi or fully automated systems.
Using an ultrasonic sewing machine brings forth a series of advantages:
# Fast and cost-effective weaving;
#
# Resilient seams;
#
# No need for consumables such as tape, clips or glue;
#
# Constant results;
#
# No cooling times and reduced maintenance costs;
#
# No shooting time for the stapler tool;
#
# Edging in one operation
# No need for needles, thread, spools and any activities related to color matching, inventories, winding and trimming;
#
# Environmentally-friendly because it does not need any adhesives and solvents;
#
# Edges get sealed without leaving any stitch holes, thus preventing penetration from chemical agents, bloodborne pathogens and other particles.
Advantage:
Instead of needles, thread, glues or other adhesives, ultrasonic sewing equipment uses a patented rotary system, coupled with high-frequency vibrations, to bond synthetic or blended materials containing up to 40 percent natural fibers.
Resembling a traditional sewing machine, the ultrasonic sewing machine channels the ultrasonic vibrations between a horn and rotating wheel, producing a localized heat buildup which causes the synthetic fibers to soften and fuse. This creates a strong molecular bond thats impervious to moisture. Explains Alleman, the resulting barrier seams are sealed, secure, ultra-reliable and soft-to-the-touch without the safety issues caused by stitch holes, glue gaps, fraying or unraveling.
