SCHAUMBURG, Ill. -- Sodick injection molding machines from Plustech Inc., Schaumburg, Ill., will showcase the unique capabilities of its equipment by injection molding microfluidic chips made of TOPAS® cyclic olefin copolymer (COC) from TOPAS Advanced Polymers, Florence, Ky., (Booth 662) at the MD&M West 2017 show Feb. 7-9 at the Anaheim Convention Center in Anaheim, Calif.

At booth 4071, Sodick will feature the Sodick GL30 micro-injection molding machine producing a microfluidic part incorporating micro details.

Live Molding Demonstration

The live molding demonstration includes a mold supplied by Plas-Tech Engineering Inc., Geneva, Wis. (Booth 541). Automation will be provided by Star Automation with a side-entry robot that will remove the part from the mold.

Features of TOPAS COC

  • The prototype application demonstrates the growing use of COC in diagnostic products such as microfluidics and microplates. 
  • It is also much easier to manufacture in volume via simple injection molding compared to alternatives like glass and silicones. 
  • With the exceptional (92%) clarity and mold detail of TOPAS COC, well counts are maximized, flow channels can be incorporated, and analyses are optimized. 
  • Due to its ultra-high purity, TOPAS COC has lower leachables and extractables than competing materials, resulting in the most reliable and repeatable results. 
  • The inert nature of the material prevents interference with reactions and analyses. 
  • Other important features include the best available UV transparency of any plastic, heat resistance suitable for PCR or sterilization, and low auto-fluorescence. 

TOPAS COC is making strong inroads in these microfluidic applications including a unique crystallization microplate from MiTeGen LLC, Ithaca, N.Y., a provider of innovative consumables for X-ray diffraction, crystallography, and protein crystallization for academic, pharmaceutical, industrial, and government research. MiTeGen’s new In-Situ-1TM crystallization plate uses TOPAS® COC for its superior moisture vapor resistance and x-ray transparency compared to competitive thermoplastics.

Applications of TOPAS COC

• The strong capability of TOPAS COC for fine detail is a key benefit for advanced microfluidic designs. One customer has used TOPAS 5013S-04 to create a line of products featuring thousands of highly consistent 3-micron diameter wells.
• Others have developed microfluidic discs for medical analyses, modular kits for microfluidic device development, and a 3D printer that utilizes TOPAS 8007S-04 for prototyping of microfluidic designs.
• Some customers have taken advantage of the strong dimensional stability and low shrinkage of TOPAS COC grades. In one example, a customer has created cylinders with a zero draft angle.

Sodick GL30

  • The Sodick GL30 is a high-performance model that offers excellent repeatability and accurate plasticization. 
  • The machine provides advanced injection for micro features with extremely tight tolerances. 
  • It includes Sodick’s V-Line two-stage plunger system, which separates the plasticization and injection processes for consistent measurement and injection of the melt stream. 
  • The 30-ton machine incorporates a true hybrid clamping mechanism utilizing an upgraded servo motor-controlled hydraulic pumping system.
