New standards of the plastics industry for devices and robots published

The Plastics Industry Association has released some new safety standards, one focusing on equipment that reduces the size of plastics for processing and recycling, and the other on robots for injection molding.

The device standard is a 47-page update on the manufacture, maintenance and use of granulators, strand granulators, dicers and single-shaft rotary mills that are driven manually, mechanically, hydraulically or pneumatically and use a rotating cutting process.

This standard does not apply to any other type of shredder or pulverizer.

The new safety requirements were issued by the machine safety standards committee of the trading group after a three-year review by representatives from all industries.

The update is accredited by the American National Standards Institute (ANSI) and was published as ANSI / PLASTICS B151.11 Safety Requirements for Granulators, Strang Pelletizers and Dicers Used for Size Reduction of Plastics.

“This document contains important information that is critical to the safety of those who work on or near very powerful machinery, said in a press release.

The machinery committee had the task of reviewing the 2004 version of the standard, in particular its scope, normative and informative references and definitions of clarity and uniformity. It was chaired by Jason Forgash, President of Bay Plastics Machinery, and David Miller, General Manager, Shredding, Conair Group.

“Our goal was to update a standard that wasn’t reviewed for too long and to ensure that our industry segment met the most current security requirements available,” Forgash said in the press release.

The committee succeeded in the collaboration that was required because the devices were used for a wide variety of applications in a variety of configurations, said Jennifer Jones, director of industry standards for the trade association.

“This group was able to apply knowledge of multiple systems to ensure that the standard accommodates the complexities of security considerations in a diverse industry,” Jones said in the press release.

The machinery committee has also published an ANSI-accredited safety standard (ANSI B151.27-2021) that covers the design, implementation, setup, operation, maintenance and modification of robots with injection molding machine systems.

These security requirements are the result of two years of collaboration between 46 voting members of the committee. Duane Royce, Vice President Robots and Automation at Wittmann Battenfeld, chaired the working group.

The resulting 36-page standard will guide users through the complexities of amalgamating plastic and robotic technologies and the corresponding safety standards for those machine systems, Jones said.

“The committee has been careful to incorporate references to existing industry standards while filling in gaps related to the integration of the systems,” she said. “Consensus standards like these help the industry safely invent and manufacture plastic products while ensuring fairness in the market.”

The two standards are available on the association group’s website for $ 100 at a member discount.
