Compression molding is one of the oldest method for thermosetting plastics.<\/p>\n

It is not possible to make PBI stock shapes by injection or extrusion molding because the fluidity of PBI is little. Therefore, PBI Advanced Materials modified compression molding procedure to optimize for PBI production and established the special method: PBI Method.<\/p>\n

The advantage of PBI Method is low residual stress and low warpage. To take the advantages, PBI Advanced Materials has applied this PBI Method to not only PBI but also other high performance plastics, e.g., polyimide (PI), thermoplastic polyimide (TPI), polyetheretherketone (PEEK), and so on.<\/p>\n

PBI Method<\/div>
PBI Method is a unique compression molding technology developed and patented by Sato Group.
\n<\/strong>PBI Method is different from a well-known compression molding procedure on which articles are pressed at room temperature and then sintered in a furnace, which is normally allied to PTFE etc. On PBI Method, articles are systematically pressed and heated in a mold and then gradually cooled. PBI Method can easily control degassing through molding process. Therefore, PBI Method can prevent voids in the articles.<\/div><\/div>\n
