Dielectrics is the leader in the design, development, and manufacture of medical devices and other products using thermoplastic materials. Whether you’re a larger OEM or a start-up company, leverage our advanced suite of technologies, innovative processes and highest quality materials to successfull.   RF (HF) welding can also be referred to as dielectric welding, and is a relatively mature technology with regard to welding plastics. It has been around for over 50 years, starting in Europe, as a result of theoretical knowledge of the first radar systems and post-war experience accrued in the field of inductive and capacitive heating of materials.

APPF Inc. is a privately owned domestic manufacturer operating out of a mod square foot facility located in Orange County, California. We specialize in contract manufacturing work building products to customer prints and specifications. We have over 30 years’ experience building medical, military and consumer products including inflatables, like structural air-beams and radar. Radio Frequency (RF) Welding: Rigid plastics, foams and films. Radio Frequency (RF) welding (or high frequency welding) is the process of bonding together materials through the use of electromagnetic energy. Electromagnetic waves are used to heat the material to a point where it begins to melt and form a bond. No external heat is applied.

New Vimko Plastics is a front runner in the manufacture of high frequency plastic welding machines, P. P. stationery machines & induction cap sealing machines. Our commitment to deliver quality at economical prices with product innovations suited for the existing & new end user have helped us to earn market across Middle Eastern countries. Our radio frequency (RF) welding services are well suited to handle both small and very large components like ’ long lb Shelter Panels (LAMS), tank liners, Oil Boom and Spill containment systems as well as inflatables, and other plastic components for the military and medical industry.

The focus on practical aspects such as weldability, optimizing part design, troubleshooting, and testing makes this book an indispensable tool for everyone involved in welding of plastics. At the same time it also conveys the basic theoretical principles of plastic welding, such as squeeze flow, molecular diffusion, and heat transfer by:   Process Description.

Radio frequency (RF) welding, also called high frequency welding, HF welding or dielectric welding, uses high frequency (normally MHz) electromagnetic energy to generate heat in materials by virtue of their electrical properties; the material to be welded must be able to convert the alternating electric field into heat.

Radio-frequency welding, also known as dielectric welding and high-frequency welding, is a plastic welding process that utilizes high-frequency electric fields to induce heating and melting of thermoplastic base materials.

The electric field is applied by a pair of electrodes after the parts being joined are clamped together. The clamping force is maintained until the joint solidifies. Radio frequency welding/sealing, also known as RF or high-frequency welding has been around for more than 60 years.

It is the process of bonding together materials through the use of high-frequency electromagnetic energy (radio waves). High Frequency welding, also known as Dielectric Sealing or Radio Frequency (R.F.) Heat Sealing is a very mature technology that has been around since the s.

High frequency electromagnetic waves in the range of radio frequencies can heat certain polymers up to soften the plastics for joining. Radio frequency welding uses high-frequency radio waves to heat the plastic surfaces of two different items as they face one another.

This heat reaches the point where the plastic surfaces begin to melt, and the two surfaces or materials blend together. Once the radio waves stop and the plastic cools down, the two different materials remain. Induction welding uses induction heating from radio frequency alternating current to magnetically excite an implant placed at the joint interface of the two parts being welded.

This implant, or gasket, is normally a composite of the polymer to be welded with either metal fibers or ferromagnetic particles. RF welding (also known as High Frequency (HF) welding or Dielectric welding) is a method of joining thin sheets of polar thermoplastic material together.

It uses high frequency (13 to MHz) electromagnetic energy to fuse the materials. A rapidly alternating electric field is set up between two metal welding bars.

High Frequency welding is the process of fusing materials together by applying high frequency energy to the area to be flexible thermoplastics can be HF welded; the suitability of a plastic for HF welding is determined by its molecular construction.

For example, polyethylene sheeting is not suitable whereas nylon 66 Stationery Book. The focus on practical aspects such as weldability, optimizing part design, troubleshooting, and testing makes this book an indispensable tool for everyone involved in welding of plastics. At the same time it also conveys the basic theoretical principles of plastic welding, such as squeeze flow, molecular diffusion, and heat transfer mechanisms.

The RF welding station uses an air cylinder activated press to compress the plastic materials while applying Radio Frequency energy. As the plastic material heats up under the RF energy, it melts and forms homogeneous bond, under the press force, taking the shape of the RF sealing dies (electrodes).

High Frequency (HF) or Radio Frequency (RF) welding is the joining of materials by supplying HF energy in the form of an electromagnetic field ( MHz) and pressure to the material surfaces to be joined.

A generator produces the energy. The tool used to supply the energy is called an electrode. The electrical energy causes the molecules.

Radio Frequency welding/sealing, often referred to as RF welding in short, is a very organized technology that has been widely used for well over 60 years. Commonly used elements for RF sealing are polyurethane and PVC.

However, other polymers like EVA, PET, Nylon, and a few ABS plastics can also be welded using this process.

RF Welding. Like with ultrasonic welding, pressure is applied to the plastics materials, but instead of heat created through friction, a high frequency electromagnetic energy (radio waves) is used to fuse the materials together.

The energy generated by this process causes the molecules in the material to vibrate, which creates heat and allows. MWGSS Plastic Welder. Designed for the welding of PVC sheeting and other plastics, in range of micron total thickness.

Compromising of a Radio Frequency (RF) generator and a fixed guillotine applicator, pneumatically operated from a built-in air compressor. Principles of High Frequency Welding. High Frequency welding or Radio Frequency welding is a very mature technology that has been around since the s.

Two pieces of material are placed on a table press that applies pressure to both surface areas. Dies are used to direct the welding process. RF welding relies on the vibration and orientation of charged molecules within the polymer chain to generate heat; consequently its use is restricted to plastics containing polar molecules.

Polyvinylchloride (PVC) and polyurethanes are the most common thermoplastics to be welded by the RF process. RF Welding. The RF Welding is also popular as it does not require special joint designs and takes less time for welding. It is exclusively used for welding of thin sheets as well as films of thickness between to in.

In RF Welding electrodes are interfaced with high frequency.
