Celanese Material Expertise Helps IVP Plastics Advance Gas-Assist Injection Molding Technology For Tubular Auto Parts

Celanese Corporation (NYSE: CE), a global technology and specialty materials company, is helping to advance gas-assist injection molding by providing material and processing expertise that IVP Plastics, a provider of solutions for thermoplastic components and assemblies, is using to reduce weight and costs of tubular cooling system parts for automotive engines.

“Celanese has a long relationship in working with IVP Plastics to solve material challenges, especially those found under the hood. Fortron ® polyphenylene sulfide (PPS) excels in these extreme heat and aggressive operating conditions that are pushing material limits,” said Edward Hallahan, Fortron PPS global marketing manager for Celanese.

Auto designers and engineers are looking for new material solutions that will help them meet fuel economy and emission standards. As engine compartments are becoming smaller and more compact, traditional metal tubing and rubber hoses are no longer an option.

“Our unique application of gas-assist molding technology can create a one-shot injection-molded, non-linear hollow shape with 90 degree turns and molded fastening points,” said James Mechowski of IVP Plastics. “Glass-filled, low-viscosity Fortron PPS is the ideal solution from a molding and performance perspective.”

The IVP Plastics molding process:
  • reduces steps in the manufacturing process;
  • eliminates traditional welding, brazing and plating processes;
  • provides a more dimensionally accurate component with no chance of rust;
  • reduces component cost and weight by as much as 50 percent.

“Celanese has a long history of working with global automotive original equipment manufacturers and tier suppliers on powertrain and underhood applications,” said Bob Newill, Celanese application development manager for powertrain systems. “Fortron PPS is a proven, high-temperature, chemical resistant material. In this application, Fortron PPS provides cost savings via lower reject rates, reduction in number of fabrication steps, shorter cycle times and higher process reliability.”
