Date:2023-04-28 09:35:22

Our customers from Finland (North Europe) placed the order one (1*) pcs of machines: Model YX-T20A Pyramid tea bags packing machine
For all the machines purchased it is clear to confirm all the information on the products so we often ask our customers to freight the samples to test and commission the machines in order that the machines and customer's products gains the best compatibility and adaptability.
After getting the confirmation &samples of the product in sizes and drawing for manufacturing the tea packing machine.
we spent only 20 working days finishing everything and made the machines ready after testing them in a satisfactory feedback.
Recently our customers sent us the positive commentar on the machines which keep running very well in their factory ever since the machines arrived their factory.
The machines was shipped via DHL courier to FI-07810 Ingermaninkylä Finland. The documentaries certificated with ISO&CO&CE together with other files necessory are sent via DHL to customer for assisting customers to clear the custom.

As below there listed the basic information on the successful transaction between PENGLAI and their Finnish counterpart:

Heat vs. Ultrasonics

Heating seals are simple: Package material or film surfaces are held together, and heated sealing bars are applied on one or both sides. Heat flows (conduction) from the bars through the material to the seal interface, where the mating surfaces melt to form a bond. Conduction sealing controls are straightforward, with temperature, pressure, and dwell time selected based on the melt characteristics of the thermoplastics being joined.


Heating samples with mould.jpg
In a conduction heat seal, a heated bar (red) is applied to either side of the mating surfaces (blue) to melt the plastic, and then pressure is applied to weld them into a bond.
Ultrasonic welding also joins thermoplastic films and materials, but it generates and applies heat and pressure differently. It generates heat by applying a vibration with a precise frequency and amplitude between the surfaces of the thermoplastic layers. The frictional heat melts the interior of these surfaces and, under pressure, creates a permanent bond.

In an ultrasonic weld, mechanical vibrations applied between two sealing surfaces create frictional heat which melts the surfaces, which are then compressed into a welded seal.

Ultrasonics Technology Advantages
Packaging engineers considering ultrasonic welding as an alternative to heat sealing are often driven by a variety of factors. These include:

• Eliminating seal failures due to contamination. Some products leave residues on sealing surfaces that can become encapsulated within conventional, static conduction heat seals, resulting in contamination, leaks, or failures. These include many food and beverage products, leafy produce, and powders, as well as feeds, viscous liquids, and oils and greases.

The vibratory motion of ultrasonic welding not only heats the sealing surfaces, it also first vibrates potential contaminants out of the seal area. For example, with thermal seals, product particles can get caught on sealing surfaces, potentially compromising them. With ultrasonics, the vibratory action and pressure not only cuts through any large pieces of a product (e.g., produce leaves), but also disperses smaller fragments and moisture out of the seal areal. This improves seal repeatability and reliability.

• Reducing material consumption and cost. A snack food packager making snack bags (6-in. size) consumes about 1 in. of total package length to produce two conventional heat seals per bag (0.5 in. each on top and bottom). Two comparable ultrasonic welds require just 0.25 in. of total package length (0.125 in. each on top and bottom), resulting in a savings of 0.75 in. (0.375 in. × 2) in material per bag with the same net product volume.

• Increasing sealing process speed/cycle rates.
Ultrasonic seals can be completed in as little as 150/msec, so cycle times for ultrasonic sealing typically do not present a bottleneck to increasing overall package cycle rates. No cooling time is required either, so sealing rates of up to 110 packages/min. are possible. By contrast, heat-seal cycles must not only complete the heat seal, but also give the melted plastic a brief cooling/set-up period to solidify, making them significantly longer.

• Need to handle temperature-sensitive products.
For heat-sensitive or potentially flammable products, including spirits and lubricants, the high external temperatures and longer cycle times involved with heat-seal bars can pose a risk of exceeding the product’s flashpoint. This problem is eliminated with ultrasonics. Similarly for heat-sensitive electronics, ultrasonic welds create strong, repeatable seals in a fraction of a second, with the heat energy constrained to the interior surfaces of the packaging material and away from the electronics.

• Reducing changeover times and improving process flexibility. If packaging demands can shift rapidly, ultrasonic welding equipment lends itself to rapid changes in production because tooling is always “cold.” When needed, operators need only swap out the converter, horn, and anvil/fixture to suit the new production requirements; input the proper process parameters to weld controls; and resume production. In contrast, conduction heat sealing equipment needs a cool-down period before the heat bars can be safely handled. Following changeover, they need a warm-up period to bring the new heat bars to proper sealing temperatures.

• Reducing energy costs. Conduction heat-sealing systems must be continually powered and maintained at a precise operating temperature, so they consume relatively high amounts of energy. For example, consider a packaging line producing 100 welds/minute over two eight-hour shifts per day. A typical conduction sealing process would require four 500-W cartridge heaters (2,000 W/hr or 32,000 W/day) to continuously maintain seal-bar temperatures.

An ultrasonic welder of the same capacity would be equipped with a power supply rated at 1,500 W. But this rating represents the unit’s peak power rating—typically not its continuous power consumption. This is because ultrasonic welds consume power only in short bursts, about 200 msec/weld, or about 20 seconds per minute of power consumption on a line running at 100 packages/min. So, an estimated power savings of 25% is extremely conservative, assuming continuous operation of the ultrasonic welder. Typical power consumption is likely to much lower, given the nature of ultrasonic welding.
