New Motion System
Integral linear-rotary design
VascuLathee represents a revolutionary approach to satisfying the demanding requirements of stent manufacturing applications. The fully integrated motion system couples automated material handling functionality with high-performance direct-drive linear and rotary motion capability. The integral linear-rotary design increases throughput by two to five times when compared to traditional screw-based or other manufacturing approaches, while still maintaining submicron tolerances on tight part geometries.
The increased throughput gives much needed flexibility in the extremely competitive stent-manufacturing environment. The higher throughput of the VascuLathe implies that fewer machines are required to produce an equivalent number of stents when compared to traditional manufacturing approaches, resulting in lower total labor costs and reduced floor space requirements. Alternatively, the VascuLathe can be used to meet increased and varied product demand within the existing manufacturing space, saving the costs associated with facility expansion.
With planetary gearbox
The innovative motor technology of the low-cost MDrives, high-torque stepping motors with on-board electronics, expands product line options to include fully integrated planetary gearboxes (PLGs). The planetary gearbox option increases the application range for the MDrive product line by increasing torque at lower speeds, enabling better inertia matching, and producing finer positional resolutions. Efficient, low-maintenance PLGs come fully assembled and integrated with every version of Mdrive, including Microstepping, Speed Control, and Motion Control. PLGs are available for each size MDrive, including NEMA motor size 14, 17, 23, and 34. Select from one-, two-, or three-stage gearboxes, and a large number of reduction ratios that range from 4:1 to 308:1. All PLGs come with an optional mounting flange and shaft keys for MDrive sizes 17, 23, and 34. MDrive is a compact, powerful, and inexpensive solution that will reduce system cost, design, and assembly time for a large range of stepping motor applications.

Silicone Bonding Process
Meets medical requirements for repeat autoclave sterilization
Surgical and dental instrument safety, design, and function can be improved when silicone grips and sleeves are custom-molded to the instruments. Minnesota Rubber's proprietary silicone bonding process creates a hermetic seal between the silicone and the over-molded instrument. This seal withstands repeated autoclave cycling and inhibits the migration of body fluids between sealed surfaces. Ergonomically designed features increase rotational control of instruments while providing a light and secure grip. Silicone molded designs are possible that satisfy requirements for accuracy, durability, comfort, and, most significantly, tactile sensitivity. They also allow for color customization of stainless steel, high-performance plastics, and aluminum instruments. In addition to surgical and dental instruments, the process has a potential fit for a wide range of medical and pharmaceutical applications.
