As with any major acquisition or purchase, there are several factors that will need to be considered and analyzed before parting with your hard-earned money. And not the least will be the price you have to pay. The analysis will require even more careful consideration when the purchase is a complicated piece of manufacturing machinery – such as a RF welding machine.
During the RF welding manufacturing process, two sections of the material to be pressed are aligned and pressure is applied to the surface of both materials. When the sealing process begins, the press collectively comes together and RF waves are diffused through the electrodes (RF sealing matrices) into the area between the materials – where the sealing process will take place.
Radio frequency waves will be ‘excite’ material molecules, which travel in RF waves and become hot as energy is released. The application of both heat and pressure promotes molding between the two parts within the device.
High Frequency Welding Machine Division
High frequency welding machines can be classified according to industry standards as follows:
- HF dielectric welding machine: RF heat sealing equipment that creates a wide range of medical supplies and car interior accessories.
The prices for these types of HF welding machines can range from $ 2,000 to $ 25,000 used, and newer models can range from $ 6,000 to $ 20,000 from China. Some brands made in the US or Europe may start from $ 100,000.
Key factors to consider when buying an RF welding machine
When you do a major purchasing decision within any companywhether it’s a new hire or a new retail campaign, can often be intimidating. Policymakers will want to ensure that they are investing company funds wisely and in a way that will produce a beneficial return. The following questions can help in this decision making process and can be applied to the purchase of an RF welding machine:
- What is the proposed or planned budget for the acquisition?
- Will the purchase be new or used?
- Can the welding machine really perform the functions you need?
- Will the machine’s throughput or output match its intended use? And for what periods can this outing be used?
- What have previous customers of this product say or say about it? Do they recommend its purchase to others?
- What exactly are the warranty and post-purchase support and maintenance options?
- Is machine support available 24/7?
- Will extensive training on how to effectively use and manage the machine be available?
- Will the supplier design, manufacture the RF sealing tooling and take samples during the machine acceptance cycle?
- What is the process for ordering spare parts – their availability, the time it takes between ordering and delivery, and the availability of an experienced workforce to service the parts?
Specific factors to consider when buying an RF welding machine
Radio frequency welding machines come in many shapes and sizes and operate within various power limits. The choice will depend on the type of product required for manufacturing and the number of products to be welded. The size of an RF welding machine depends on the contact area of the material or the size of the product and the thickness of the materials that will be used during the bonding process.
Specific manufacturers use steel, brass and aluminum to produce dies used in RF welding. The type of die determined for the particular project will depend on a variety of factors including design complexity, cost, and robustness.
- Steel dies cost less, but are prone to rust and other problems and can be difficult to repair.
- Brass dies cost much more, but have high energy efficiency and strength, and are easy to repair.
- Aluminum dies, sometimes described as magnesium dies, mean inexpensive and simple machines to build. They work well for complicated designs but require up to 25% more power than brass dies to achieve comparable bond strength.
Maintenance of an RF welding machine to avoid unforeseen breakdowns
In order to maintain and protect the longevity of any RF welding machine, periodic and skillful maintenance is essential. When an RF welding machine suddenly goes offline, there can be serious ramifications such as loss of productivity and delays in order fulfillment resulting in lost revenue and hence profits.
A structured and systematic maintenance plan should contain clear and concise steps for the following periods:
- Daily maintenance,
- Monthly maintenance,
- Annual maintenance,
- Ad hoc maintenance.
Conclusion
The attraction of RF welding is the flawless, flawless weld it renders, and RF welding can be performed on common materials. like pvc, Polyurethane and EVA, etc….
Asking how much an RF welder can cost is like asking the length of a piece of string. The most prudent purchase of such an expensive machine will depend on the precise business requirements which stipulate exactly what the welding machine will manufacture, the environment in which it will be used and with what materials, and to satisfy which models or models. Also, how much to produce, and when, is also a crucial determining factor.
