The Process

How Emabond Welding Works

A proven four-stage process from part analysis to production-ready welds — all engineered in-house.

01

Joint Design

Our engineers design optimal joint geometry for your specific part and application requirements.

02

Susceptor Formulation

Custom electromagnetic susceptor material formulated for your resin and weld requirements.

03

Fixture & Machine Build

In-house design and fabrication of welding fixtures and RF welding equipment.

04

Test & Verify

Full RF coil, power, and fixture testing before customer sign-off on part specifications.

Key Differentiator

Everything Built
In-House

Emabond engineers design, build, and test customer welding fixtures, manufacture machines, and validate applications — all before the customer gives verification. This means tighter control, faster iteration, and guaranteed results.

View All FAQs
No surface preparation is required. Unlike adhesive bonding, Emabond welding does not require cleaning, priming, or surface treatment — the process welds directly to the thermoplastic substrate.
Yes. Emabond technology is uniquely capable of welding dissimilar thermoplastic materials — such as PC to PP/TPO — that cannot be joined by traditional welding methods. This opens significant design opportunities.
Cycle times vary based on part size, geometry, and material. However, Emabond welding is typically fast — often 5–30 seconds per weld — and there is zero cure time, so parts are ready for the next process step immediately.
No. The RF heating is precisely targeted to the weld joint interface only. Internal components, electronics, or sensitive materials inside the part are not exposed to damaging heat or vibration.
Absolutely. Emabond welding is highly suitable for robotic and automated production lines. Emabond engineers can design fixtures and systems for robotic application of susceptor material and automated welding cycles.
Yes. Emabond Solutions holds IATF 16949 (automotive quality management) and ISO 9001:2015 certifications, both verified by DNV·GL. We are also a proud member of the Plastics Industry Association.
