FLASH CUTTING

Service Detail from National Rubber Corporation


PROVIDING ENGINEERED SOLUTIONS FOR YOUR FLASH CUTTING
Usually, when it comes to producing custom rubber parts, die cutting is the most common production method. National Rubber now offers the next generation alternative to die cutting, an ATOM Flash Cutter machine that eliminates the need for rule dies.

What is flash cutting?
Flash cutting is a type of CNC machining where there are no tooling costs involved. Unlike traditional die cutting, flash cutting uses CNC equipment to hold the rubber in place and cut shapes and parts with material thicknesses up to 1.00 inches. Because there are no dies involved, flash cutting eliminates the need for tooling costs.

What are some of the benefits of flash cutting?

  • Fast turn-around times
  • Rapid prototyping
  • Optimal material utilization
  • Minimal loss of material
  • Extremely smooth edges
  • Cutting capacity up to 60” X 120”
  • No dies needed for new business
  • No dies to store or repair
  • Reduces labor costs – one operator can run multiple machines simultaneously

 

The ATOM flash cutting machine is a computer controlled, high output system that produces a part from a common CAD file. You simply supply the CAD file in DFX or DWG format, or National Rubber can create the file for you. Dimensional changes to a part can be made just by revising the file or creating a new one. The system is particularly good for prototype parts, short runs, narrow widths and thick materials. Moreover, unlike water jet cutting, flash cut parts do not get wet and the cut quality is better on most materials. Unlike laser cutting, there are no gases, no odor or toxic fumes. The flash cutter’s preciseness allows us to hold tight tolerances. Fact is, the flash cut produces parts to tighter tolerances than die cutting, without the expense
of tooling. No lost time waiting for dies to be made. No die charges. Fast turnaround time with exceptional precision. Moreover, with a cutting capacity of 60” X 120”, large and complex designed gaskets and seals are fabricated with ease. Our engineers simply convert your drawings or samples into a CAD format and our flash cut system does the rest.
