Metal Tubing Capabilities

In addition to laser cutting and CNC machining, Wytech offers a variety of advanced stainless steel tube grinding and forming technologies.

Tube Forming

With the integration of additional resources into the expanded Rahway, NJ, facility, Wytech now has under one roof a host of advanced and conventional tube forming and fabrication technologies.  This includes Four-Slide, punch presses, end forming, swaging, and more. Also, Wytech’s engineering and toolmaking staff are ready to assist in the design and development process to assure maximum production efficiencies are achieved.

We offer a complete listing of tube forming features including:

  • Bending
  • End shape
  • Expansion
  • Forming
  • Flaring
  • Bulging
  • Notching
  • Slotting
  • Lancing
  • Dimpling
  • Swaging
  • Skiving


Tube flaring is the process of tube end forming to create a tight seal. Flaring creates a funnel shape at the tube’s end so it exactly matches the dimensions of whatever the tube is to be fitted against.

  • Max flare + flange ─ 1.5x tube OD; OD flaring with tubing starting as small as 30 Ga (0.0120″)
  • Equipment ─ Vaill end formers, Wauseon end formers, and more


Tube skiving, also known as scarfing, is the process of cutting metal material off in slices. Skived tubing is often used in catheters and other applications where guide wires exit the shaft of the tube.


Tube swaging is the process of reducing the outer and inner diameter of a tube. Swaging is generally used in the medical industry, as well as in industrial and aerospace applications.

  • Reduce tubing sizes, pencil points, and more
  • OD as small as 25 Ga (0.0200″)

Expansion / Reduction

When you need sound, thin-walled tubular parts, expansion and reduction is the process used to achieve that. We use quality, precision machines that are built to provide defect-free products, quickly.

  • Maximum expansion ─ 1.5x tube OD
  • Equipment ─ Vaill end formers, Wauseon end formers, and more

Stainless Steel Hypotube Grinding

In the medical device industry, precision components are essential. Making sure that accuracy in measurement is strictly maintained, as well as providing a wide range of products and services, are both important factors when choosing a grinding company. When you choose to work with Wytech, you can rest assured that we will adhere to your exacting specifications to provide you with quality components.

Wytech’s proprietary point grinding systems offer burr-free electrochemical point grinding that provides fast set-up and fast changeover times while creating varying grind angles for needle sets.

Needle Styles include:

  • Back Bevel
  • Bias Grind
  • Diamond Point
  • Menghini
  • Razor Edge
  • Stylet
  • Tri Facet Lancet
  • Trocar

We provide exemplary grinding services for a variety of materials

When you choose to work with Wytech, you will appreciate the speed of development we strive to provide. We know you need your components in a timely fashion, which is why we work hard to take you from concept to product quickly. However, we never cut corners or provide you with an inferior product. You can rest assured that our grinding services are of the highest quality, using the latest technologies.

We are able to work with various tensiles of the following materials:

  • Stainless Steel
  • Cobalt
  • MP35N
  • 17-7
  • 17-4
  • 420 SS

Learn more about our FlexGrind needle tips and points

Wytech’s proprietary 5-Axis systems produce unique, multi-profile grinds and features not possible with conventional tip or point grinding equipment. Particularly, Menghini features or skived and scalloped tubes with varying grind angles for biopsy, aspirator needle sets, and more are ideally suited for Wytech’s FlexGrind program.

  • Types: bias grinds, lancet points, blunt ends, trocars, bevels, diamond points, trephine, and other unique tip geometries and profiles
  • Needle Tip: typical A & B bevel syringe-type grinds
  • Point Grinding: conical point for wire
  • Chemical-etch marking and anti-core capabilities


  • Bonding Mandrels
  • Biopsy Needle Stylets
  • Neuro Interventional Guidewires
  • PTFE Guidewire Cores
  • Sizing Mandrels
  • Stylets
  • Hypotube Skiving
  • Orthopedic implants/instrumentation
