Description
1.1.
The RF Forming/Welding System
The RF generator is the foundation of a sealing, forming, and/or welding system. The generator
supplies RF energy to a peripheral sealing head that is used to process RF-reactive thermoplastic
materials. The peripheral component of the system controls the generator.
Vante offers many off-the-shelf peripheral devices with diverse features that can be used for
most applications. Vante also offers engineering support for those who design their own custom
peripherals.
Custom peripherals must incorporate a matching network provided by Vante.
Vante will provide all of the components needed to support custom peripherals, such as
controllers, coaxial cables, interface cables, footswitches, matching network, forming/welding
heads, etc., at additional cost.
1.2.
Theory of Operation
The 3800 / 3806MOD (3807MOD) System uses RF energy to seal, form, and weld certain types
of thermoplastic. The thermoplastic must be an RF-sensitive dielectric. The RF energy heats the
thermoplastic, allowing the material to change shape and bond, depending on the type of force
applied. When the material cools under the applied force, it retains its new shape or bond.
The 3800 RF generator produces RF power at a maximum of 200W. The frequency is controlled
by a solid state oscillator/amplifier operating at 40.68 ±0.020 MHz. The peripheral 3806MOD
(3807MOD) sealing head component applies force to a material throughout the heating and
cooling phases of the process.
The operator controls the dwell time and clamp time, so one system can process various
materials and tubing sizes.
1.3.
Operator Safety
WARNING:
Vante recommends strict adherence to the procedures specified in these user
manuals. Misuse or modification of an instrument may result in unsafe or
hazardous situations.
The 3800 / 3806MOD (3807MOD) forming system is designed to be used in a controlled
manufacturing environment by trained personnel. The 3800 / 3806MOD (3807MOD) system
applies RF equipment to form and weld thermoplastic tubing or parts.
Vante RF devices meet or exceed appropriate electric safety standards. These devices pose no
electrical shock hazard when used with properly fused and grounded outlets. Refer to section 5
for additional information on RF safety.
WARNING:
This Vante product is designed for indoor use only.
