SpinStack® is patented tooling technology used in the injection molding industry to manufacture plastic related products.
What is SpinStack®?
SpinStack® is integrated into injection mold to reduce manufacturing operations to create, but no limited to:
• Multi-material
• Mechanical assemblies, some of which cannot be done thru external automation
• Tamper Evidence
• Large wall section parts
SpinStack® reduces cycle time and improves product quality thru the method of “not letting go” of the part to perform additional operations or tasks.
Gram Technology SpinStack® technology is patented across the world. To date over 20 patents have been issued to our organization.
Several of our patents have gone thru reexamination and as a result have become even stronger in the marketplace.

Definition of Spin-Stack®
Rotation of mechanical inserts or blocks, whether inside the mold itself or part of the mold frame, with a common goal of rotating the least amount of insert or block weight in the process. With the least amount of insert or block weight, Spin-Stack® molds can run faster, safer, and longer. Spin-Stack® is not axis specific which means you can perform rotations not only on the vertical axis but also on the horizontal axis too.
Using Spin-Stack® mechanical inserts or blocks, molded parts can be held and controlled in a more effective / positive manner between locations. Essentially the mechanical inserts or blocks become fixtures to maintain control of the molded parts while being moved or transferred to a new location.
Various multi position techniques or combinations thereof can be applied such as additional cooling, secondary material (i.e. 2 shot, 3 shot), assembly of product, labeling, painting, insert loading of label / metal / electronics, inspection, and part removal to name a few.
Other names Spin-Stack® can go by in the industry are:
- Spin Cube Mold
- Rotary Cube Mold
- Rotating Stack Mold
