ANSI Reaffirms SPI Molding Standard as "American National Standard"

February 8, 2013

The American National Standards Institute (ANSI) has reaffirmed SPI’s “Vertical Clamp Injection Molding Machines (VCIMM) - Safety Requirements for Manufacture, Care and Use” (ANSI/SPI B151.29-2002 (R2013)) standard as an American National Standard. The scope of this standard applies to all new VCIMMs that process plastic materials and inject plastic material into a mold held closed by a vertically acting clamp(s). The SPI Injection Molding Safety Committee continues to lead efforts connected to SPI’s horizontal injection molding and vertical injection molding standards.  For more information or to join the committee, contact Melissa Hockstad.
