TechneMed maintains a HEPA filtered environment specifically for the sub and finished assembly of medical devices. Beginning with the silicone elastomer parts, we mold or extrude to your specifications and assemble your devices to strict QSR and industry standards. Our secondary equipment and facilities include specialty jigs and fixtures, automated machinery, multiple assembly stations, environmentally controlled clean rooms, flow booths, and experienced people.

There is almost no limit to the configurations in which two or more silicone rubber components may be joined to create assemblies for special functions.

TechneMed provides the assembly of silicone subcomponents in special environments, such as clean rooms and HEPA filtered facilities, to meet OEM cleanliness requirements.

The most common assembly methods for joining multiple silicone rubber subcomponents include insert molding and bonding. The insert molding process involves injection molding around an existing part or parts. The bonding process entails joining one or more silicone components together with silicone adhesives. Other methods include tipping, reinforcing, dipping, and cuffing.

Silicone rubber assemblies can include airways, shunts, occluders, laparoscopic devices, and many others.

A multi-component assembly - This catheter begins with a molded tube, which is internally reinforced with a stainless steel spiral wire. The wire, specified by the customer to provide kink resistance, is inserted into the mainshaft I.D. and then encapsulated. Next, a molded balloon is bonded onto the distal end. The tip of the mainshaft is beveled and coated for ease of insertion. The check valve assembly is then attached through bonding for cuff inflation. The assembly also has several secondary processes, including holes pierced in the sidewalls for drainage and printing on the side for identification.

Secondary Operations
After components are molded or extruded on our manufacturing line, we do secondary operations or completely assemble silicone devices using these operations:
  • slitting and punching
  • trimming and beveling
  • tipping
  • bonding
  • marking
  • skiving
  • cuffing
  • assembling purchased components

We perform: inspection, bundling, leak testing, fabricating, silk-screen printing and full assembly of accessories such as valves, electrical connectors, and locks as required.

Assembly Applications
Some of the many assembly applications include:
  • airways
  • nasal splints
  • occluders
  • shunts
  • epistaxis catheters
  • paired tube assemblies
  • many laparoscopic devices
  • feeding and oxygen catheters
  • your design requirement
