Semi-closed die Forging

 

A Hybrid Forging Process 

Thanks to computer-aided design, close customer collaboration and creative forging techniques, Scot Forge has pioneered "semi-closed die" forgings—a process that combines the advantages of open die forging with the near-net shape of closed die forging.

With over 100 years of combined experience, our Forging Development Team of engineers works to convert previous fabrications or castings into near-net-shape forgings of higher quality.

Simulation & Modeling Reduce Risk, Time & Costs

Collaborating closely with customers, the team runs sophisticated simulation and modeling software to tailor a forging process that optimizes time/cost savings. This software also allows for process validation prior to actual manufacturing, reducing risk, and ensuring the success of each project.

Hybrid Forging Compared To Castings And Fabrications

Forging delivers significant economic, manufacturing, and quality advantages when compared to alternative metalworking processes such as directional strength, structural strength, and impact strength.

Directional Strength

By mechanically deforming the heated metal under tightly controlled conditions, forging produces predictable and uniform grain size and flow characteristics. Forging stock is also typically pre-worked to refine the dendritic structure of the ingot and remove porosity. These qualities translate into superior metallurgical and mechanical qualities and deliver increased directional toughness in the final part.

Structural Strength

Forging also provides a degree of structural integrity that is unmatched by other metalworking processes. Forging eliminates internal voids and gas pockets that can weaken metal parts. By dispersing segregation of alloys or non-metallics, forging provides superior chemical uniformity.
