Re inventing the art of sewing

  Sew Fine, LLC is a small invention shop in San Francisco. We specialize in developing hand crafted robotic sewing equipment for manufacturing class 3 medical devices. Our sewing machines are custom made not converted and are clean room ready. Many implantable devices  have been FDA approved that are sewn on our machines. Harry Shonteff (owner) often works as an industrial sewing consultant offering:

• Design and 3D motion modeling.

• Prototyping and production sewing equipment.

•  We have a complete machine shop including  4 axis CNC machining.
   

Most medical devices are designed then prototyped using hand stitching. When the product goes into production often there is no sewing technology capable of producing the correct stitch in the required locations.  Class 3 medical device manufacturing is generally a combination of new technologies and highly skilled hand sewing operations. This combination of talent and technology is used to produce finished implantable devices. Many medical devices manufacturers have replaced much of the hand sewing with automated sewing equipment often utilizing  vision guided robotics. This offers a  large reduction in manufacturing time, reduced labor related injuries, and a more precise sewn product as each stitch is positioned by computer controlled motors
 

We work directly with our customers as industrial sewing consultants. To develop custom made sewing equipment to replace many hand sewing processes, one seam line at a time.

Specializing in sewing small ( .750 and under) and very small ( .080 and under) tubular device. We are interested in working on extremely challenging sewing applications. If you have a sewing project that can not be sewn with conventional sewing technology we would be happy to work with your team to develop a automated solution to your sewing challenges.
