Precision Machined Components

Using state-of-the-art equipment and highly skilled personnel, we are able to produce small, tight tolerance components made from stainless steel, titanium, platinum, MP35N, various plastics and other materials in prototype through production volumes.

Our capabilities include CNC turning machines, CNC conventional lathes, wire, sinker, and small hole EDM, centerless grinding, CNC milling, precision deburring, laser welding, light assembly, special cleaning processes, automated passivation, die casting and injection molding service. We can manufacture complex configurations from micro-miniature up to 1” maximum diameter capability. We excel on parts 3/16” diameter and smaller. Our tolerances range from +/-.0001 to +/-.001 and even +/- .00005 on certain features. Lastly, our surface finishes typically range from 8u” to 32u” (capable of 4u”) with tight cosmetic requirements.

Tube Drawing

SINCERE TECH draws precision tubing for the stent market, including alloys in Nitinol, and 304 Stainless Steel, Cobalt Chrome alloys like L605, MP35N, and other proprietary or custom alloys by customer request. Sizes range from .100″ outside diameter down to .020″ and smaller. Mechanical properties can be tailored to customer requirements.

Precious Metal and Clad Tubing

SINCERE TECH defines the industry standards for the tightest tolerances, thinnest walls and radiused edges for tubing, marker bands and electrode rings. With our dimensional control and size capabilities, we can help reduce the profiles of medical devices. We also offer clad tubular products that incorporate two or more materials into one tube. With a clad, various materials may be combined to achieve unique properties.

Deep Drawing

SINCERE TECH is a world leader in the design and manufacture of miniature, ultra-high precision tubular components. Utilizing deep drawn technology, we are one of the few manufacturers in the world that can produce custom miniaturized parts to 50-to-1 length-to-diameter ratios, with tolerances as low as ±0.0001″ (0.0025 mm).

Precious Metal and Clad Wire (Wire Drawing)

SINCERE TECH manufactures precious and high-value metal drawn wire products. We focus on materials that offer specialized engineering properties for pacing, defibrillation and other medical device applications. In addition to single alloy wire, we also offer a clad wire (two or more materials clad together into a single wire). With a clad, various materials may be combined to achieve unique properties.

Fabricated Wire Products

SINCERE TECH specializes in every aspect of precision wire component fabrication and assembly. Beginning with a basic spool of wire, SINCERE TECH transforms many materials into a range of products, from straightened and cut tooling mandrels to sophisticated coronary guidewires that include complex core grind geometries and platinum coil spring tips. Included in our wire expertise is the ability to engineer Nitinol wire products that capitalize on the unique super-elastic and shape memory properties of this material. We also manufacture both single and multi-filar coil assemblies for the most demanding applications, from cardiac rhythm management to catheter reinforcement. Whether you require a simple straight or complex wire component involving winding, coiling, grinding, welding and assembly, SINCERE TECH can deliver.

Extrusion

Precision Monomer and Composite Tubing Manufacture

SINCERE TECH manufactures precision monomer and composite tubing and catheter sub-systems to desired properties with the thinnest walls, tightest tolerances and smallest profiles for the best performance. We offer precision tubing that can be constructed from multi-layers of different materials, braid or coil reinforcement, and with variable flexibility along with the tubing. Additional capabilities include multilumen, tapered tubing, wire coating/insulation and coextrusion.

Materials include Polyimide, PTFE, FEP, Tecoflex, Tecothane, Memory Plastic, Nylon 11, Nylon 12, Pebax (several durometers), Nylon 6/6, and Polyethylene. Tubing sizes can range from .002″ ID to .200 with walls ranging from .0003″ to .010″. Braiding can consist of ultra-small flat or round stainless steel, Nitinol to non-metallic materials.

Virtual Tubing Model

SINCERE TECH offers tubing and catheter shaft modelling through the use of propriety software. The model will predict the optimum layer thickness and the combination of materials for the designer’s desired performance. The output of the model based upon material and dimensional inputs are crushability, flexibility, stretch, pushability, torquability, and kink radius. This allows the design to be developed with the shortest development time possible as design iterations can be made within the software instead of the manufacturing process.

Metal injection molding

SINCERE TECH’s proprietary precision metal injection molding process offers net shape metal parts to tight tolerances, which can be exceptionally cost-effective in volume in comparison to precision machined parts.
