'Spin Stack' components are now standardized.

A new line of off-the-shelf components has been developed for the Spin Stack tooling of Gram Technology, Scottsdale Scottsdale, city (1990 pop. 130,069), Maricopa co., central Ariz.; settled in 1895 by Winfield Scott, inc. 1951. It is a resort and retirement center in the Phoenix metropolitan area. , Ariz. Gram Technology of Denmark Denmark (dĕn`märk), Dan. Danmark, officially Kingdom of Denmark, kingdom (2005 est. pop. 5,432,000), 16,629 sq mi (43,069 sq km), N Europe. has partnered with Progressive Components, Wauconda, Ill., to supply standard components for Gram's rotating ro·tate

1. To turn around on an axis or center.

2. center-stack technology. This development allows molders licensed by Gram to purchase the components to build their own molds. It also helps customers obtain replacement parts more quickly. Gram and Progressive are developing pre-engineered Spin Stack kits for single and multi-component tools, and they will provide joint engineering support to customers.

The Spin Stack concept typically uses four-sided indexing core sets between the stationary Stationary can mean:

Fixed in position, or mode: immobile.
Unchanging in condition or character.
In statistics and probability: a stationary process.
In mathematics: a stationary point.
In mathematics: a stationary set.

and moving platens. The center stacks allow for multi-component molding that can incorporate in-mold decorating, coating, and/or assembly. Gram: (480) 659-0426/PTDirect: 984UV * Progressive: (847) 487-1000/PTDirect: 242FR
