Ultrasonic Welding Plastic PP Filter

For situations where ultrasonic welding of such PP plastics requires sealing, the first requirement is to have a reasonable structure of the product joint surface, usually designed as a convex groove structure. If the structure is limited, it can be designed as a shear type ultrasonic structure, and the effective height of the ultrasonic fusion line is about 1mm;

Furthermore, for suggestions on the selection of Ultrasonic Welding Plastic PP Filter, we can use our company's H-80 ultrasonic welding machine, which has a frequency of 15khz, a power of up to 3200W, and a high ultrasonic amplitude, which has a good effect on welding PP materials. In most cases, it can meet the welding needs;

For the material itself of PP plastic, it is recommended to use a type with harder hardness points. During the welding process, there may be overflow situations, which can be overcome by setting mechanical limit devices of ultrasonic machines;

FAQ

Q:  What are the operational risks of ultrasonic welding plastic PP filter?

When the ultrasonic welding is processing, its upper die will drop and the lower die will rise. The larger the range of up and down, the larger the processing area. The operation steps of the ultrasonic automatic welding machine require the operator to first carry out the upper mold and lower mold of the plastic processing workpiece from the right front and left front, and then heat it with ultrasonic to make the upper and lower molds reach the appropriate temperature, and then press, because the high temperatures between the upper and lower molds fuse with each other to form a complete plastic product, Then take the product out of the operation area of the ultrasonic plastic welding machine.

The upper and lower dies of ultrasonic welding plastic PP filter move faster, and operators are prone to certain risks when feeding. If the operation speed cannot reach the speed of its upper and lower molds, it may have a certain impact on human health. In the whole operation process, people's head and hands are more likely to be injured, and in serious cases, they may become disabled or die. In this case, the rapid production of ultrasonic plastic mold is not the main problem, and the safety production is the important problem that the factory needs to consider. There can be no fluke about this safety problem, which needs to be solved in time.

Q:  What about high frequency ultrasonic plastic welder application scope?

High frequency plastic welding is used for general thermal welding of plastics, leather and cloth. High frequency ultrasonic plastic welding machine has accurate positioning, good performance and strong flexibility. It is usually used for small product processing, with high production efficiency and convenient operation. High frequency plastic welding applications: soft and hard rubber, leather and cloth for special purposes. It can be used for welding, fusion, thermal bonding, hot pressing, etc., which is applicable to watch belts, belts, leather goods, CD bags, tents, luggage, packaging bags, hot water bags, air cushions, infusion bags, blood bags, catheter bags, car cushions, car floor mats, car synthetic leather chairs, sunshades, door armrests, sporting goods, stationery, medical supplies, etc.

Q：Can PP plastic sealing strips be welded using ultrasonic waves?

Yes, ultrasonic welding is related to materials and product design structure. The plastic sealing strip welds black and blue plastic sheets together, and the selection of materials is very important. The ultrasonic fusion of PP material is good, but some customers may say that the welding is not firm and has a significant relationship with the material. PP should be harder, and softer PP material is not easy to weld.

The structure of plastic sealing strip products requires the design of ultrasonic welding lines.

The ultrasonic mold for PP plastic sealing strips will be made into the shape of a knife mold and welded in one go.

Can PP plastic sealing strips be welded using ultrasonic waves? It is possible. As long as the material has good fusion performance, there is no problem with welding.
