Product welding requirements:
First, we must understand the structural shape and typeface of the product, size, welding area, material properties,
dimensional accuracy, welding strength, whether watertight, and whether surface requirements are
Clear whitening prevention, production efficiency, finished product rate, output, use and life of molds and equipment.
The more complex the product structure, the more difficult the welding process, and it is related to whether ultrasonic
welding and manufacturing can meet its welding needs.
General thermoplastic plastics can be used for ultrasonic welding, but there are some such as: PC, PP, PET, PBT and other
high-temperature high-strength fiber composite industrial plastics need large
Power digital circuits (output power is strong and stable) are soldered with ultrasonic waves. The low power of normal
ultrasonic conversion causes fake welding or non-melting of the product. By dissecting
The welding surface of the product looks at the phase melting effect, or drops test and use tensile force to determine
whether the welding strength of the product meets the requirements.
Dimension accuracy: The size of the product welding finished requires that each product welding size be consistent
(within the allowable tolerances), the smaller the tolerance, the higher the accuracy.
Watertightness: That is, electronic or vacuum container products become watertight (watertight) and can withstand
certain pressures after welding.
Clear protection against whitening: After welding on a transparent product is completed, there can be no whitening
at the melting position. To avoid affecting the appearance.
Finish rate and output: improve the speed of production of qualified products, ensure quality and finished product
rates, and reduce non-performing products to fewer / none. Improve efficiency and competitive advantage. It's modern.
A swords for innovation in manufacturing.
The use and life of molds and equipment is the key to cost control. The longer the life, the lower the cost (many people
think that cheap equipment costs less to produce).
The cost calculations of equipment life, maintenance, product quality, output, scrapping of sub-products, management
labour, etc. were ignored. Stable and reliable production requires output power
A powerful and stable ultrasonic welding machine with the right function - save time and effort. Save your mind and be
efficient. The device's matching power leaves as much excess or space as possible,
Do not run at full capacity for a long time to avoid causing damage to the ultrasonic system components and shortening
the service life of the equipment. Mold structural design, materials, amplitude, connection empty load
Power consumption is related to maintenance.
Product welding requirements: Firstly, it is essential to understand the product’s structure, shape, parting surfaces, size,
welding area, material properties, dimensional accuracy, welding strength, watertightness, surface requirements for
transparency and prevention of whitening, production efficiency, yield rate, production volume, the usage and lifespan of
molds and equipment. The more complex the product’s structure, the higher the difficulty of the welding process. This
affects whether ultrasonic welding and manufacturing can meet the product’s welding needs. Generally, most
thermoplastics can be welded using ultrasonic technology. However, certain materials such as PC, PP, PET, PBT, PPF, PPS,
and POM, which are high-temperature, high-strength, and reinforced composite engineering plastics, require powerful
digital circuits (with strong and stable output power) for ultrasonic welding. Low-power ultrasonic conversion can
result in false welding or incomplete fusion. By examining the product’s welding surface through sectioning,
one can assess the degree of fusion.
