Custom RF Tooling Services
At MarkPeri, we take pride in offering products that meet and exceed our customers’ expectations. Our capabilities include custom RF tooling to match your specific requirements. Our custom design process accounts for several essential factors, including frequency range, power levels and operating environment, to ensure a high-precision result.
This RF tooling service offers several benefits for your manufacturing operation. Customization enhances the RF system’s performance by optimizing signal integrity, alignment and connectivity. It also enables more efficient manufacturing and testing and can reduce long-term costs by minimizing RF system errors.
RF Welding Die Design for Multiple Applications
We’re experts at creating specialized welding dies that encompass several crucial aspects. We will select the most appropriate material for your project based on factors like the ability to conduct RF energy and withstand intense pressure during the welding process. We’ll also consider the die’s shape and ensure it conforms to the contours and dimensions of the newly welded parts.
Additionally, we’ll design a die with a smooth, precisely machined surface to provide appropriate material contact and prevent weld imperfections. The completed die will also have a tight tolerance to ensure accurate material welding.
We have extensive experience designing RF welding dies for a wide range of industries and applications:
- Medical: Our RF welding dies can create consistently tight seams on IV fluid and blood bags. They also form sealed connections for tubing to ensure they meet stringent medical standards.
- Automotive: We can adapt our welding design process to automotive industry applications like manufacturing upholstery and door panels. It can also form the seams in convertible tops.
- Packaging: Our design services are ideal for developing RF welding dies to secure packaging and protect the contents from contamination and tampering.
RF Tooling Experts
Radio frequency (RF) welding/heat sealing is an essential process in the manufacturing of products for the medical industry such as the intravenous (IV) fluid bags used to collect blood, urine and other bodily fluids. RF sealing entails the creation of radio frequency waves to generate heat that welds two or more layers of plastic film together. The molecular action produced by the RF waves is akin to cooking food in a microwave oven. Effective RF welding relies upon the use of appropriate techniques and equipment, along with high-performing RF tooling, to ensure the finished product contains a strong seal.
Tube/Mandrel RF Sealing
Tube/mandrel sealing is a common technique when manufacturing IV bags. This RF tooling-based process involves welding the IV bag’s insertion tube between two plastic film layers to create a tight seal around the flexible container’s perimeter and the tube weld within the perimeter.
The use of tubes requires double-cycle tooling that includes mandrels. In mandrel RF welding applications, the tubing slides over a mandrel and is positioned between the two plastic layers. The plastic material is then placed between the upper and lower dies of the sealing machine. The application of heat generated by the RF waves and pressure created by the die results in the fusing of the two plastic layers.
RF Tools for Sealing Medical IV Bags
Radio frequency tools typically used for the RF sealing process of medical bags include a brass upper die affixed to an aluminum tool and jig plate, and a lower weld nest constructed from aluminum. The weld nest normally contains a buffer board attached to the seal area. The buffer board helps prevent heat-sinking of the metal nest, while also providing an insulated landing spot for tear-seal tool edges.
Important RF Tooling Considerations
Key considerations in RF tooling include ensuring that uniform thickness is maintained, as well as the removal of any sharp edges or corners. It is also imperative to determine the appropriate level of RF energy that is fed into the seal area. Using RF sealing equipment that contains a generator with a high-quality arc suppressor will help regulate the voltage output by stopping the output before damage to the plastic film or die can occur. This will also ensure the temperature does not drop to a level that is insufficient for sealing to take place.
