Product Description

Injection Molders Supply Co. (IMS), headquartered at 3514 Lee Road, Cleveland 20, Ohio, was an aftermarket supplier of replacement cylinders, band heaters, heated nozzles, and ancillary components for the major U.S. injection molding machine lines of the postwar era. IMS published replacement cylinder and heater assemblies dimensioned specifically for popular machines including the Reed-Prentice 8-ounce frame, and supplied molders nationally with rebuild and upgrade components.

Per contemporaneous trade-press records, IMS marketed double-capacity replacement cylinders with twice the wattage of original-equipment heaters while operating at lower surface temperatures — products positioned for plastic molders producing thin-wall sections requiring improved heat distribution.


Asbestos Content

Plaintiffs alleged in publicly filed asbestos litigation that IMS replacement cylinders, band heaters, and nozzle assemblies were supplied with asbestos-containing thermal insulation through at least the early 1970s. The asbestos insulation was specified to retain process heat, protect operators, and stabilize melt temperature on the heated process surfaces.


How Workers Were Exposed

Workers replacing IMS-supplied cylinders and band heaters on Reed-Prentice and other injection molding machines were exposed during installation, removal, and replacement work:

  • Cylinder installation — Unpacking and installing new IMS replacement cylinders required handling asbestos insulation jackets
  • Band heater replacement — Routine maintenance work that disturbed asbestos cylinder and band insulation
  • Cylinder removal during major rebuilds — Stripping and replacing the entire IMS cylinder assembly handled asbestos-bearing components
  • Field service work by IMS technicians, used-equipment dealers, and rebuild shops handling IMS-supplied components

Plaintiffs alleged that plastic molding operators, plant maintenance mechanics, millwrights, and field-service technicians were exposed to airborne asbestos fiber during these routine activities.


Plants Where IMS Components Were Installed

IMS aftermarket cylinders and band heaters were installed at U.S. plastic molders running Reed-Prentice 8-ounce and other-capacity machines from the 1950s through the 1970s — including molders producing dispenser pumps, trigger sprayers, electrical components, household products, and packaging.

This information reflects facility history, exposure pathways, and product documentation drawn from publicly filed asbestos litigation, federal regulatory records, and industry archives. It does not constitute a finding of fact or liability with respect to any specific manufacturer, supplier, or facility operator.


If You Worked With IMS Replacement Cylinders or Band Heaters

If you installed, maintained, or rebuilt IMS-supplied replacement cylinders, band heaters, or nozzle assemblies on injection molding machines during the asbestos era — and have since been diagnosed with mesothelioma, asbestosis, lung cancer, or another asbestos-related illness — you may have legal rights.
