How long do workers have to file an asbestos claim?

Overview Product Facts Trades

Litigation Record: Information below reflects allegations in publicly filed asbestos litigation — plaintiff allegations, not findings of fact.

Product Description

Watson Stillman Company was a U.S. manufacturer of hydraulic injection molding presses during the 1940s through 1970s era. Watson Stillman small-shot machines — including the 6-ounce injection model — were widely installed in plastic molding operations producing electrical components, household products, packaging, and industrial moldings.

Per publicly filed allegations in U.S. asbestos litigation, Watson Stillman injection molding presses incorporated asbestos in components of the heated process system.

Asbestos Content

Plaintiffs alleged that Watson Stillman presses incorporated asbestos in one or more of the structural roles common to small-shot injection machines of the era:

Heating cylinder insulation — The heated injection cylinder operated at process temperatures of 350°F to 600°F. Plaintiffs alleged the cylinder was wrapped in asbestos-containing thermal insulation.

Band heater insulation and gaskets — The electric band heaters clamped around the cylinder were alleged to be insulated and gasketed with asbestos-bearing material.

Nozzle insulation — The heated nozzle was alleged to be wrapped or gasketed with asbestos-containing material.

Hydraulic system gaskets and packing — High-pressure hydraulic flanges and packing were alleged to incorporate asbestos sealing material.

How Workers Were Exposed

Workers were exposed during routine press operation and maintenance:

Band heater replacement disturbed asbestos cylinder insulation
Cylinder rewrap during major rebuilds required handling asbestos-bearing material
Mold changes required working at heated nozzles and platens
Hydraulic gasket and packing replacement released asbestos fiber
Heater wiring and electrical maintenance required work in asbestos-insulated areas
Machine rebuilding for resale required handling asbestos-bearing components

Plaintiffs alleged that plastic molding operators, machine setup workers, mold-change crews, plant maintenance mechanics, millwrights, plant electricians, and bystander workers were exposed to airborne asbestos fiber during these routine activities.

Watson Stillman 6-ounce hydraulic injection molding machines appear in contemporaneous Modern Plastics for-sale equipment listings alongside Reed-Prentice, HPM, Stokes, and Farrel-Birmingham equipment from major U.S. plastics manufacturers — indicating broad distribution into the postwar U.S. plastic molding industry.
