Tubing
Modification and Secondary Processing
Finished
components, tubing sub-assemblies and unique molded parts
from a wide range of fluoropolymer and thermoplastic materials
can be manufactured using proprietary and cost-effective technologies.
Here is a brief overview of some of the most popular types
of components:
 Catheter
Assemblies
Catheter products include constructions from PEBAX®, FEP, PTFE
Teflon®, braided tubings and other materials. These examples
show a range of technical and production capabilities.
Flares
Flared
FEP, PFA, PTFE and PEEK tubing provide maximum sealing and
mechanical properties. Flares are molded, not stretched or
stressed. A range of custom configurations are possible at
very competitive prices.
Introducers
Custom
split introducers are made in various French (diameter) sizes,
tab lengths, transition cones, overall lengths and tab decorations.
Typically, these introducers are radiopaque white FEP material.
Mesh
or Braid
A
variety of novel components and assemblies utilizing braided
material. Typically, braided material is only one element
of a complex construction. Braids may include a variety of
polymeric fibers as well as stainless steel wire. Combinations
of processes, materials and structures make many engineered
solutions possible.
Tubing
Assemblies
Extruded
tubing of PTFE, FEP, PFA, silicone rubber, Tygon®, and
other polymers are combined with fittings, flares and other
components for use in medical, diagnostic, test and industrial
equipment.
 Molded
Parts
This
is a precise molded FEP Teflon® part for a flow control
application. Notice the thick and thin wall sections. The
inside taper is a critical compound angle. Application requirements
do not allow flash, gate marks, weld lines, distortion, surface
defects, or shrink voids. This part is an example of complex
and precise shapes that are not moldable by conventional technology.
Common injection molding defects are avoided with proprietary
technology.
Metal
Tube Micromaching (Stent Components)
In
nitinol or stainless steel our principals offer precise execution
of your designs and specialized manufacturing solutions. While
industry standard laser capabilities are available, we also
utilize alternate laser technologies to reduce the heat affected
zone. Feature sizes of under 50 microns with precise tolerances
are achievable.
Molded
Parts and O-Rings
Compression,
Transfer, Blow Molding and LIM (Liquid Injection Molding)
for all medical and industrial applications in Silicone Rubber,
Viton® and other elastomers. Medical grade materials are molded
in a Class 10,000 certified clean room at an FDA registered,
ISO-9001 facility. Molded parts may be combined in complete
assemblies with tubing or other components.
O rings
can be manufactured from 0.020” ID to over 120 inch diameters
with exacting tolerances. This type of part may also be produced
through close tolerance cutting of an extruded profile to
significantly reduce tooling charges.
Viton® is a registered trademark of DuPont Dow Elastomers.
