Kinecoil Division - Precision coiling systems

What does Kinecoil offer the medical device market?

David Willens: The Kinecoil division at Kinefac provides multiaxis servo-controlled systems for the medical device industry. We offer high-precision CNC single-point and two-point coiling systems designed to produce precise coils and helical spring forms typically found in medical device applications.

These coils are commonly used in guide-wire delivery systems and stent delivery systems, marker bands, pacemaker leads and aneurysm intervention devices, and in other high-precision medical devices typically found in cleanroom environments. All systems are capable of forming coils in stainless steel, platinum alloys, tungsten, music wire and other materials. Kinecoil also offers precision coiling tooling to meet the stringent high-accuracy needs of most medical device coils.

We offer two standard coiling systems. The Micro-Coiler system is designed to produce very precise small coils and springs using wire diameters from 0.025mm (0.0010in) to 0.152mm (0.0060in). The new Kine-Coiler system is designed to produce larger coils using wire diameters from 0.127mm (0.0050in) to 0.762mm (0.030in) with the same level of precision.

Coils can be made and automatically cut in discrete lengths of up to 5m with varying diameters and pitches, depending on coil configuration. Kinecoil offers coil support units based on specific user needs.

What's the advantage of your coiling process?

Kinecoil micro-coiling systems use the deflection coiling process to make coils complete, without the need for secondary operations such as stretching and trimming the coils. This results in higher production rates than other methods. Variations in coil diameter and other complex shapes are easily obtainable by simple programming. Simple changes in programming can have a controlled effect on coil diameter, pitch and droop or stiffness. Tool moves can be programmed as low as 0.000254mm (0.00001in). With Kinecoil Micro-Align tooling, the precise placement of the tools into the machine is simplified, reducing operator set-up time.

What other types of services do you provide?

Kinecoil application engineers work with customers in the early stages of product development to design coil attributes that are technically feasible. Prototype and development services prove out design concepts and, through process development, confirm that the technical requirements of the product can be achieved in a production environment. In-house laboratory equipment allows us to provide sample coils as well as small-lot production as required.

Customised equipment and parts-handling units are available to meet each customer's requirements. Full application engineering support, including mechanical, electrical, process and tooling development, is available from our knowledgeable team. In-house and on-site service, as well as phone support, training and troubleshooting, are also available.

Where do you see the industry going in the future?

Based on customer feedback, we are seeing a greater demand for coils made out of nitinol and other exotic materials. Alongside this, there is a demand for coils made from smaller diameter wire sizes, as access to the smaller arteries and passages in the human body becomes more critical. We are also seeing an increased level of interest in being able to produce a coil directly over cylindrical pins and tube-like components.

What new developments are planned?

The new Two-Point Kine-Coiler Coiling System with six-axis CNC controls will be introduced at MD&M 2018 in California, in the US. Some of its unique features include user-friendly coil program generation, coiling-point digital skew angle readout and onscreen programmable feed roll pressure. Our development team is working to address the future needs of the medical device market and are currently in the development and testing phases of several different areas. We are excited to complete our developments and introduce new innovative processes to meet the evolving industry needs at upcoming trade shows and media outlets.
