Ultrasonic welding is to transfer energy to the welding surface through high-frequency vibration to cause the temperature to rise, then the plastic melts, and then through a holding time to cause the plastic to solidify to complete the welding. The ultrasonic welding machine is not pressure welding, because there is no pressure to complete the entire welding, and only pressure can not complete the entire welding process.
are also often used for welding plastic pallets.
Welding plastic pallets are that are welded into a whole plastic tray by ultrasonic welding machines. Nowadays, most of the welded plastic trays are double-sided plastic pallets that can be used on both sides.
Ultrasonic can weld the pallet HDPE material: the advantage is non-toxic, tasteless, odorless white particles, melting point of about 130 °C, the relative density of 0.941-0.965. It has good heat resistance and cold resistance. The welded tray has good chemical stability, high rigidity and toughness, good mechanical strength, dielectric properties, and good resistance to environmental stress cracking.
Advantages of ultrasonic welding of plastic pallets: the use of recyclable plastic pallets is about 10 to 15% lower than the cost of purchasing disposable wooden pallets; 2, to solve the quality problems when using wooden pallets; 3, the use of high-quality plastic pallets can improve product safety; 4, the use of plastic pallet packaging cycle mode to improve corporate environmental image and social responsibility.
2. Flexural force: Instant deflection force can prevent the goods on the pallet from scattering when lifted by forklift. 2. Bending: After the plastic pallet is placed on the shelf, its bending will gradually increase, and the bending in the automatic warehouse cannot exceed ten millimeters. 3. Impact resistance and durability. 4. Usability: light weight, simple operation, forklift easy to enter, stable size. 5. Hygiene: no decay, no moisture absorption, easy to rinse, easy to dry.
