Filtration & Mesh

Easily and Quickly Fasten Mesh Foils and Sheets

Sunstone’s resistance seam welding technology (RSEW) makes light work of creating mesh foils and sheets. Depending on your needs, Sunstone offers two simple solutions, one which is sure to solve your mesh foil and sheet welding challenges.

It All Starts with the Power Supply

Sunstone provides two solutions, an AC power supply to create a continuous seam, or a CD power supply for a stitched seam at a lower cost. Both systems utilize a rolling electrode to deliver the energy and create the weld. With either solution, fastening mesh foils or sheets to frames or other components can be any easier.

Here at Sunstone, we have the privilege to work with and provide welding solutions to some of the largest and most successful companies in the Dental & Orthodontic Industry including Pall Corporation, Phoenix Filters and many others.  Through our years of experience and work, we have developed and built the products to help you with your application.

Filtration Welding Applications:

  • Filter Basket Welding
  • Hermetic Sealing
  • Faraday Cages
  • Multi- Layer Filter Materials
  • Expanded Metal Welding
  • Small Filter Assemblies


AC Constant Seam Welding:

AC Welding uses an AC power supply to supply a constant and precise flow of energy that creates a continuous seam weld. This is ideal when working to develop a Hermetic seal. Also, this method works great to weld every wire within a mesh. The heat of the weld is controlled both by the speed of the wheel ( or Electrode Dwell ), and the power setting that is selected.

Therefore, one can accomplish a hotter weld by slowing the electrode speed, increasing the power, or decreasing the pressure applied to the workpiece. Consequently, a seam weld can be used to create a foil pouch or pouch cell. The Sunstone AC welding systems are ideal for Pouch Cell Welding. Also, an excellent application for the AC welding system is screens and filter baskets. Filter Basket Welding can easily be accomplished using the AC welding system. Screens can be welded to backing plates and thicker materials to accomplish perfect metal screen welding.

CD Roll Spot Welding:

Roll Spot(RS) welding uses a proprietary technology with the Sunstone Capacitive Discharge (CD) welding systems. CD Roll Spot Welding is simple, as the wheel rolls across the workpiece the power supply will fire welds at a set interval. The weld Process will create a stitch weld, similar to a sewing machine. The user varies the speed of the roller electrode to get the desired distance between welds. This distance can vary in adjustable to nearly touching for a near seam weld.

Additionally, the significant advantage is the cost. Durable, reliable welds can be performed at a more affordable price than the AC welding system. If a perfect seam is not required in your application, the CD Roll Spot is an ideal fit for you.

  • Micro Resistance - AC Welder

    AC Resistance Seam Welders are used to complete AC Resistance welds. These would include both spot welds and seam welds. Ideal for creating a continuous seam weld, foil welding, Pouch cell welding, and mesh or screen welding. The primary applications include the creation of hermetic seal with a pouch or package. Additionally, AC Resistance seam welders create and build filter assemblies, filter bodies, and attaching mesh screen to a strainer basket. Additional applications include filter baskets, battery cells, and any metal filter or screen.

  • Micro Resistance - Dual Pulse CD Spot Welders

    The dual pulse industrial capacitive discharge (CD) spot welder provides a substantially larger amount of weld energy combined with a finer range of power adjustment. As with Sunstone's other spot welders, the CDDP welders produces clean, strong welds. Pulse one heats the weld area to eliminate surface contaminants and seats the welding electrodes. Pulse two then makes a strong, secure weld. Both pulses occur within milli-seconds.

  • Linear DC

    The Sunstone Linear DC welder is a completely unique resistance welding system with closed-loop feedback. Utilizing new patent pending technologies, the Linear DC welder has the power of a High-Frequency Inverter and the precision of a Linear DC. As mentioned, this is a completely unique product. It isn’t an HF welder since it does not require an external transformer, and it isn’t like typical Linear DC welders because it doesn’t use transistors to control the energy output. Yet, this product is able to perform the same functions as both of these technologies, and in most cases it has capabilities that exceed those of other HF or Linear DC welders – offering high repetition rates, fine low-energy control, and short or long weld times – without any of the drawbacks and inconveniences.
