titanium nitride (TIN) coatings
For metal implants, burrs, drills, blades, electrosurgical paddles and all types of medical and industrial applications. Offers outstanding wear resistance and improves ease of cutting. Super hard and corrosion resistant, TiN coatings feature non-stick properties and eliminate galling and seizing where metal-on-metal contact is necessary. A metallic gold appearance is typical, but other colors are available.
Advantages offered are:
- The PVD (physical vapor deposition) process ensures uniformity and cleanliness.
- Thin film coatings (typically 3 microns) to minimize dimensional impact
- Uniform coating with no edge build up
- Dense, non-porous
- Non-toxic and FDA compliant for implants and food processing equipment and gear
- Conductive, non-oxidizing
- Low fatigue (high compressive stress)
- Three times harder than chrome and “off the Rockwell C scale.”
- Inert and stable
- High temperature resistance up to 1,100 deg. F (600 deg. C)
- Three dimension coating -- not line-of-sight
- Excellent adhesion beyond mechanical, with no blistering, flaking or chipping
- Environmentally friendly alternative to plating
PTFE coatings are a popular choice to improve lubricity on wire mandrels for better release, as well as on needles and probes to improve fluidics. We offer these coatings on all types of metal products. Recent developments include a dry-release PTFE coating which has significantly improved lubricity without flaking over time.
pfte coated mandrels
304 SS Fine Wire Mandrels in stock from .004" - .060", PTFE coated and uncoated wire. Quick turn, low minimum orders.
New proprietary technology permits coating of fine wire with a thin, smooth, pinhole-free finish of Teflon®-PTFE fluoropolymer resin to provide release or slip properties and/or electrical insulation.
Applications include providing an internal forming mandrel for extrusion of small-diameter plastic tubing with extremely accurate bore and use as magnet wire in electrical coils.
Release coating thickness is typically 0.0002 ±0.0001 in. (5.1 µm ±2.5 µm). For electrical insulation, coating thickness is typically 0.001 in. (25.4 µm).
The manufacturer has coated silver-plated copper wire with diameters from 0.012 to 0.080 in. (0.3 to 2.0 mm) and on stainless steel wire from 0.001 to 0.040 in. (25 µm to 1 mm) in diameter.
Lubricious coatings are available in specialized UV-cured formulations with hydrophilic properties for use in medical devices such as introducer sheaths, cardiovascular and urology catheters and short-term implanted devices. While there are many coatings solutions available, we offer the ability to provide either contract coating of your device or a fully manufactured, OEM catheter that includes the application of this proprietary hydrophilic coating. Samples, coatings engineering support and regulatory consulting are available.
Parylene can be the optimal choice for improved lubricity when applied to wire, tubing and other metal substrates. This coating is ideal on silicone rubber and other elastomers, transforming the “sticky” surface into a smooth, even finish.
- Nitinol thin film sputtering
- Polymer coatings
- PAD printing
Parylene is an industry standard for conformal coating, providing chemical, electrical, mechanical and biological barriers for implants and electronic components used in everyday life.
- Key advantages of these coatings for our clients are:
- FDA approved, biocompatible
- MIL-spec and UL approved
- Fully conformal and pin-hole free; not prone to crack initiation
- Inert and transparent yet with excellent adhesive properties
- High dielectric strength
- Barrier to oxygen, CO2, moisture, chemicals and solvents
- Non-fouling properties
- Room temperature process allowing coating of thermally sensitive materials
- Applied in a vacuum, offering excellent control and cleanliness
- Thicknesses from 1 – 76 microns in a single process
In house cleaning capabilities include automated aqueous washing machines, plasma equipment, ultrasounds, ovens and vapor degreasing.
Quality control is assured by statistical process control, sampling, thin film analysis, gauges and microscopes managed and implemented by highly experienced and capable staff. Cleanliness testing is via an Aqueous Technologies Zero Ion G3 organic tester.
nitinol thin film sputtering
Via a vacuum physical deposition process, Nitinol is sputtered onto surfaces to create nano and micron thin coatings. Applications include electrodes, neurovascular devices and implants, micro-actuators, drug delivery systems and bioMEMS.
silicon implant coatings
Silicone polymer dip coatings offer corrosion resistance, low coefficient of friction, and electrical insulation. These coatings are pin-hole free, hydrophobic and chemically inert.
Medical grade printing services utilize medical grade inks done in a controlled environment. Pad printing is a specialty, including all colors, custom design and art work done in –house, but we also use offset and screen printing, Unusual capabilities include radiopaque inks for marking implants and delivery systems.
