Plastic Ultrasonic Welding – Powered by SWISS-SONIC Ultraschall AG
How Swiss-Sonic Ultrasonic Technology been used in Industries
Written by : Managing Director SNRSONIC Sdn Bhd Abd Wahab (awahab@snrsonic.my)
🔥 Ultrasonic Technology developed and produced 100% in Switzerland by SWISS-SONIC ULTRASCHALL AG since 2000, are used to help industries in many ways. SNRSONIC SDN BHD is the authorized partner for Malaysia, Singapore, Thailand and Indonesia Market.
Plastic Ultrasonic Welding, mainly used to joint 2 Thermoplastic materials permanently. A frequency between 20kHz to 100kHz are used. Ultrasonic travel through a given material causing heat to develop in the material itself, thus resulting in local melting of the plastic due to absorption of vibration energy. Industries that used these techniques: Electronics, Medical, Packaging, Appliance, Automotive, Textile/non-woven and..…many more
🔥 Ultrasonic Welding are widely used due to below benefits:
✅No consumables: no glue, screw or any consumable or any additive
✅Very fast cycle time: Welding take around 0.5 – 2second only (no other process can beat it)
✅Very Accurate: up to +/- 0.1mm part thickness
✅Highly Repeatable: Very low dppm
✅Versatile Equipment: Some equipment can last until more than 30 years…not good for me, as cannot sell more welder…. 🤣🤣🤣
Main technique of Welding are :
✅Metal Insertion – Cheaper moulding option (avoid adding insert during moulding)
✅Plastic Staking /Spot Welding – used a lot in automotive industries, If you do not believe me, break your internal car door panel, break you dashboard. (Refer video Spot Weld – Auto)
✅Welding – Mostly plastic……and yes, we can weld Metal too.
✅Blister Packing / Packaging Seal- When you buy toothbrush, notices how they are packed?
✅Cut n Seal – rubber, textile non-woven and woven material
✅Cut of Food – Clean, hygienic, and precise cut (did not damage the food)
We share some of video that we are able to capture. There are many more we cannot share due to P&C. We have all the solutions from a simple handheld welding until a standard Press. For Complex system, we can customize the welder for your needs.
