Progressive Components Introduces New Roller Pullers™ for Parting Line Sequencing

Wauconda, IL, U.S.A. – Progressive Components, a leading supplier of components for the injection mold, blow mold and die cast tooling industries worldwide, announces the addition of its new Roller Pullers™, advancing the standards over other devices for controlling the sequence of openings for parting lines within a mold.

Progressive’s new Roller Pullers feature these advantages:

Smooth, Friction Free action ideal for cleanroom operations
No grease required on external components
Spring ‘sight window’ for adjusting pull force
Mounting pattern compatible with industry standards
Competitively priced

“There are many ways to hold a plate when controlling parting line sequences,” explains Glenn Starkey, president of Progressive Components. “Roller Pullers are simple and effective approach, engineered especially for mid-volume production runs targeted to perform beyond a million cycles.”

In 3-plate molds, use the Roller Pullers to draw the “A plate” away from the “X plate”, exposing the runner. For stripper plate molds, Roller Pullers are a means to retain a B side, “X plate” or hold the cavity side plate while side actions are being pulled. In addition to parting line sequence control, Roller Pullers can be used to pull or retain double ejector plates, or to retain any other floating mold plate.

Should “real world” conditions require additional pull force, tool room personnel are able to adjust pulling force up to 2-1/2 times the original setting using the spring sight window.

“Sometime it’s overkill, or worse yet detrimental, to contend with a mechanical latch lock for controlling parting line sequence,” comments Steve Johnson, maintenance systems manager at Progressive. “Roller Pullers are very straightforward and can easily be installed in new tools or stocked in the molder’s tool room to use as replacements for other devices.”

Roller Pullers fit within Progressive’s Friction Free™ engineering standards with no lubrication required for the product to function long-term, making it a unique choice for medical molds or tools with downstream paint operations where part contamination is a concern.
