By having an in-house Tool & Die shop, OGS can have better control over the design of customers’ tools and fixture needs. Our die shop maintains, repairs, and builds tools complete for our Stamping needs and those needs of our customers.

A compound tool or die is designed to simultaneously perform more than one operation with each stroke of the press. For example, a compound die may blank and pierce in a single stroke.

Compound tooling allows for faster production because a single movement on the press can create more than a single feature on a part. Multiple compound tools can be used in lieu of progressive tooling to offset a larger capital investment. The challenge then becomes, this directly affects the cost of the part being produced as now there are more operations added.

Progressive die stamping is a multi-stage sheet metal forming process, where the final shape is given in two or more sequential operations. In progressive die stamping, coil is fed through all the stations and the blank is pierced and formed in the earlier stations. In the last station, the part is blanked and discharged from the skeleton. If the part cannot be formed within the metal strip (i.e., very deep drawing is present or the part size is large), transfer die stamping is used. In transfer die stamping the part is first blanked and then formed and pierced.

Since a progressive die (generally) is used in a single press, the part size is limited to small and medium parts. Larger parts may require transfer die stamping and a tandem press line. Progressive tooling is great for high-volume stamping projects where design changes are few. Operations such as blanking, forming, drawing, piercing, tapping, staking, etc. can all be performed in a single tool and highly efficient.
