Frequently Asked Questions

Get answers to common inquiries about our machines and services.

What is the difference between HF and ultrasonic welding?

High-frequency (HF) welding uses electromagnetic energy to heat and bond polar thermoplastics like PVC. Ultrasonic welding uses high-frequency vibrations to generate heat at the joint of thermoplastic parts. HF is ideal for large-area sealing, while ultrasonic is better for small, precise joints.

Do you offer customization for specific applications?

Yes, we specialize in custom machine design and tooling. Our engineering team works closely with clients to develop solutions tailored to unique production needs, materials, and output requirements.

What support do you provide after purchase?

We offer comprehensive support including installation assistance, operator training, technical documentation, and ongoing maintenance. Our team is available for troubleshooting and spare parts supply globally.

Are your machines compliant with international standards?

Yes, our machines are designed and manufactured to meet CE, ISO, and other relevant international safety and quality standards. Certification documentation is available upon request.
