Our turks heads play a valuable role in the medical device industry because they have high accuracy, they are extremely adjustable, and produce high-quality metal products. Turks heads use a draw die technique, yet they incorporate two pairs of rolls, one set is vertical, and one set is horizontal, to provide even more options for the medical device industry.

Turks heads are used for the direct formation of round material to squares, rectangles and special shapes. A turks head is a metal forming machine that can be compared to an adjustable draw die but is infinitely adjustable in its limiting dimensions. A turks head machine operates on the rolling mill principle and imparts the same qualities to metal as a rolling mill does superior surface finish, accurate size and shape, and improved grain structure of the metal.

For the medical industry, FENN turks heads have been used to produce:

  • Shaped wire for orthodontic devices
  • Various medical devices
  • Eye glass frames
  • Research and development

Nitinol, titanium wire, and stainless steel are commonly alloys used among the medical industry for various applications.

FENN turks heads can be customized to suit your specific medical applications. To those unfamiliar with this type of equipment, the question naturally arises – “Why use a turks head in place of other drawing methods?”

  • Turks head permit forming directly from round to square, rectangles and special shapes
  • A turks head can take a bigger reduction per pass, when compared to other forming methods
  • Because the rolls are infinitely adjustable there is great flexibility in production capabilities
  • Lower maintenance costs since rolls can be reground for continued use
  • Turks heads maintain uniform tolerances
  • The turks head rolling principle produces less inherent friction

FENN Manufactures a range of precision standard pull-through and power-driven Turks Heads with high bearing capacities at high speeds. Our design and manufacturing techniques ensure that our metal forming machines are able to hold close uniform tolerances on shaped wire.

Our swaging machines service many facets of the medical industry. Swagers are a popular method to shape or resize tubes, rods, and wires because the chip-less forming processes produces no waste – so precious materials are not scrapped. Not only are FENN swaging machines cost effective, the end product they produce offers an impeccable grain structure and strength, which is vital in the medical device industry. Integrating automation into the swaging process provides the capacity for exact replication with each production run. In the medical industry precision is crucial to quality production. Using automation during the swaging process can ensure face-paced production of both quality and quantity.

NF and 1F sized FENN swagers are commonly used to produce fine points on a variety of medical related devices such as needles and surgical needles with no radius. Small OD material is possible on FENN NF swaging machines.

Swagers can be used for multiple applications, simply by switching the dies a new application can be performed. On FENN NF and 1F sized swagers, the changeover time is very fast which allows for maximum productivity and uptime. FENN designs and manufactures dies in-house – contact us for spares.

Our swaging machines have been used to make:

  • Marker bands for catheters
  • Hypodermic needles
  • Medical & surgical tools
  • Surgical needles
  • Optical instruments
  • Dental water picks
  • Dental implants
  • Cable and wiring for electrodes

FENN’s swaging equipment is fully integrated by the OEM. We are a single source supplier, eliminating the need for multiple vendors for the production of one system. Integrated automation improves equipment safety and product quality. Save time with collaborative robotics and allow FENN to design, coordinate, test & validate your system for you.

 

Flat wire has many uses in the medical industry. FENN wire flattening and shaping lines use extreme precision to make high-quality wires out of both ferrous and non-ferrous materials. In the medical device industry, reliability and quality are of the utmost importance, which is exactly what our wire flattening and shaping lines have to offer – and with a full line of optional accessories, there is no requirement too demanding.

FENN drawbenches and draw blocks are used for drawing various medical tubing.

A majority of medical drawbenches are hydraulic, because this configuration lends itself well to shorter drawing applications.

Titanium, nitinol, and stainless steel tubing can be used on FENN drawbenches to produce:

  • Hypodermic tubing
  • Medical tubing

Within the medical industry, FENN drawbenches can be used to draw out tubing, reducing it for the next step on the production process. Some of these next steps can include:

  • Cutting
  • Internal isolation
  • Internal wiring

FENN’s drawbenches can be designed with different levels of automation including but not limited to:

  • Part loading
  • Part unloading
  • Inline cutting equipment – which creates additional efficiency within the process

Draw Blocks: FENN draw blocks are used with continuous coil of wire or tube – much larger lengths than what is drawn on a drawbench – the block can draw tube or wire down to a certain size then the material can come off the block and go to another process such as:

  • Annealing
  • Cutting
  • Machines for twist and cut
  • Machines for applying coating onto the product
