新加坡采购需求：胶带切割机，超声波切割，胶带切割机，超声波切割

Hi there! I'm interested in some details regarding the ultrasonic cutting machine. I noticed that the specifications on your website list a frequency of 18KHz; is there an option available for a 35KHz version? Additionally, could you clarify what certifications come with the machine, such as CE, CB, or CCC? I also watched the video with the thicker nylon tape, and I'm curious if this machine is suitable for cutting laundry labels, typically made from nylon or polyester, often referred to as satin ribbon in the industry. Furthermore, could you provide the retail price for a single unit? Lastly, would your company be open to accommodating custom requirements? Looking forward to your prompt response! Thanks!
