Here are 5 key things to acquaint to your RF welding able
Radio Frequency welding is a circuitous and accepted welding to band High Frequency Welding Machine acute abstracts calm by appliance electromagnetic activity and burden to actualize abounding altered types of products.
But afore the assembly action begins, it is actual important to accommodate your RF welding able with key advice for authentic and expedient artefact assessment.
Here are 5 key things to acquaint to your RF welding able if accepting your artefact assessed:
Intended Function
The aboriginal angle in free if your artefact is RF Weldable is the advised action of your product. Burden is one of the key factors in free RF Weldability.
If you are bearing a artefact appropriate to accommodate awful aeroembolism air and the autogenous burden of the artefact measures added than 30 psi, it will not be a acceptable applicant for RF Welding, as some RF Welds will not be able to authority beneath the acute pressure.
If the advised action of the artefact is to bear abrasion, again it is important to bethink that a added able bolt that is RF Weldable will accept to be used. If the artefact will be acclimated for absolute animal contact, customer use, or aural the medical industry, the actual acclimated will a lot of acceptable be appropriate to accept a specific rating.
Size
The additional angle to accede in artefact appraisal is the admeasurement of the artefact you are searching to accept RF Welded. An RF welding apparatus works like a columnist columnist or a bite columnist application. Ample articles could affectation a botheration to the RF welding able due to size.
The bigger custom applique RF welding machines are those acclimated to band mattresses. An RF welding able will charge to apperceive if their accessories will plan calmly with your product.
Many ample articles such as accident covering tops, landfill liners, and barter tarps are fabricated with assorted (sometimes hundreds of bar welds) that anatomy continued seams and bend hems
Configuration
RF welding is a two dimensional process, but added circuitous three dimensional articles can be created with erect seams. How your artefact is configured is key. The accomplish acclimated to actualize that three dimensional artefact are two dimensional and are completed one footfall at a time. However, not all three dimensional articles are acceptable candidates for an RF Weld.
For example, abnormally shaped three dimensional articles that cannot be configured appliance a accelerating two dimensional action may not be achievable for RF welding due to its complexity.
Application
Application is the fourth angle that requires accurate appliance in RF Welding. Your best in abstracts acclimated accept to be carefully called based on the advised appliance of your product.
As with the advised function, the appliance may crave abstracts that backpack specific ratings, abnormally for industries with abundant accent in medical, animal contact, or customer use. It is analytical that these articles be fabricated with RF acute materials, (materials that are able to be RF Anchored together), yet still accommodated the binding guidelines for that industry.
Drawings
Lastly, it is important to accommodate your RF welding able with assets of your advised or absolute product. CAD blazon assets are the best way to back your concept.
Your assets do not accept to be three dimensional or CAD, but they do charge to acutely back the abstraction of the artefact to anyone that has never apparent it before. If you move to the acquirement of tooling, we would charge DXF or DWG cartoon files to actualize the tooling.
With these 5 key things in mind, you are now bigger able to accept your artefact adjourned by an RF Welding professional. At davison-machinery, we can calmly actuate if your artefact is applicable to produce, as able-bodied as accommodate you with appraisement on tooling, prototyping, and assembly for as abounding units as you require.

Basic Properties of An RF Welder
The properties of electromagnetic energy have always lent themselves well to sealing plastics. Just as a microwave oven heats food, an RF Welder heats a plastic part to the point at which it can bond with another plastic part or to another surface. The technique is faster and cleaner than conventional thermal welding and also produces a stronger bond.
As with any system that generates high levels of electromagnetic energy, there are potential safety problems associated with RF welder operation. When designed, operated, and maintained properly, the systems produce extremely low levels of radiation in the vicinity of the operator.
If the shields designed to protect the operator from overexposure conditions are not properly deployed, if the shields are in some way defective, or if the design of the welder itself does not pay adequate attention to shielding, the level of radiation to which the welder operator may be exposed can be orders of magnitude higher than what is considered safe. Clearly, the potential for severe overexposure exists.
The power generated by an RF welder ranges from about 1,500 Watts to more than 60,000 Watts, a power level comparable with the highest power radio and television transmitters. While the power radiated by a broadcast antenna is emitted from an antenna located high on a tower, an RF welder delivers its energy inches from the operator.
For years, many RF welders were not well designed in terms of RF safety. That situation has changed, and the vast majority of the welders being sold today address the RF safety issue. However, there are countless older welders still in use.
However, there are basic steps to achieving RF safety with RF welders, see as follows.
1. Determine the RF field levels under normal operating conditions. This usually requires measurements.
2. Establish a simple safety program that includes procedures for both operators and maintenance personnel. Periodic equipment checks are a good idea.
3. Train both operators and maintenance personnel. For example, RF Welding Machine operators should constantly check to be sure that the shields are functioning properly. Much can be achieved by simple observation.

The material most common in High frequency welding is PVC and PU
Principle and advantage of High Frequency Welding Machine
The main principle of high frequency welding (HF welding) is based on di-electric heating of the material to be welded.
The objects that needs to be welded are clamped together between two metal electrodes and a high frequency voltage is supplied. As a result the molecyles in the material starts to vibrate and heat up. Eventually the material will melt, and the force supplied by the electrode will melt (fuse) the two surfaces together. After cooling a permanent seam has been created. The resulting weld seam can be as strong - or even stronger - than the surrounding material.
The great advantage of HF welding is the speed of welding: The material is heated from the inside and fuses quickly, within few seconds.
Compared to high frequency welding, a lot of other methods (hot air, infrared radiation, laser) the energy /heat is supplied from the outside. This means that the heat must first penetrate the material in order to heat the contact-surfaces, thus risking to burn the top layer of the welded material.
You could compare this to heating your food in the microwave oven vs in a traditional oven.
What materials can be HF welded?
The material most common in High frequency welding is PVC (sometimes called simply vinyl) and PU (Polyurethane). The material can be thick or thin, reinforced or coated. It can also be plain, coloured or structures / patterened.
Observe that bonding requires the two materials to flow and mix easily. Thus PVC Welding Machine materials can be welded with PVC components and PUR sheets needs special PUR components. Carmo has developed a unique PVC/PUR material that maintain a lot of the properties of the PVC and still allow for good bonding on PUR based foils and sheets.

Davison-machinery can be used to Automatic Blister Packing Machine weld
Davison-machinery can be used to plastics weld a variety of medical devices, supplies and Automatic Blister Packing Machine , such as this inflatable bladder used under hospital mattresses to prevent bed sores.
The usual way to connect two TPEs is to heat them up and melt them together. But Radio Frequency (RF) welding can be a better method when the plastics are made of polar resins with high dielectric loss factors. RF welding works quickly and the welded material can be handled coming off the machine.
The problem with the RF welding process is that non-polar plastics are “invisible” to RF energy unless modified with significant amounts of polar additives such as EVA (ethylene vinyl acetate).
Genesis Plastics Welding in davison-machinery has a proprietary technology which was developed in the 1980s called davison-machinery Plastics Welding. This technology can seal polar and non-polar plastics such as polyethylene and polypropylene. It may be particularly useful for medical device makers that want to replace PVC with environmentally friendly TPEs for use in disposable, single-use medical products.
The difference between common RF welding and davison-machinery lies in a proprietary bolt-on technology. Common RF welding requires a buffer underneath the plastics being welded to prevent holes and over-stimulation of the polar molecules. Instead of a buffer, davison-machinery incorporates a durable mechanical catalyst that makes RF energy visible to non-polar materials and weldable in a number of substrates including film, foam, wovens and non-wovens.
Because there’s no need for additives to boost polarity, the material and overall process costs are less. With davison-machinery, more types of plastics such as TPE can be welded.
RF Welding Machine Utilizing turn tables, in-line indexing and single and double shuttle trays, the company can weld film up to 82x42-in. and 0.00025-in. thick. Most film, co-extrusions, multi-laminates, wovens, non-wovens, foam and fabrics can be welded with this licensable technology. Types of plastic include: polyethylene, polypropylene, polyester, nylon and bioplastics.

The best high frequency welding machine suppliers
The best high frequency welding machine suppliers is davison-machinery's High Frequency Welding Machine >>> Davison-machinery is the world’s leading brand in induction welding equipment. With two decades of success in solid state technology, and over fifty years of process knowledge, Davison-machinery solid state HF Welder is the most advanced, reliable, field-proven welders available in the world today.
High frequency welding – which is also known as radio frequency welding – is a technique for passing extremely intense vibrations through a brass bar and onto two or more pieces of material with such an effect that the material melts underneath the bar.
Once the vibrations stop, the material re-forms as a solid having melted together with the other layer of material. This means in effect that you are taking the molecules of two separate pieces of material and joining them together at a chemical level.
A high-frequency weld will only occur where there is direct contact with the brass bar and so it is possible to get very thin welds and very precise detailing using this technique.
The Davison submersible case range is manufactured using this technique which gives us the precision to be able to ensure that the clamping system will work on every case.
High Frequency Welding Machine is a much more precise operation than heat welding because you are able to control the intensity of the vibrations and the time which they are applied to the material in order to create a scientifically precise bond between the two materials
