Hot Forming | Super Plastic Forming (SPF) Hydraulic Press

Beckwood manufactures hot forming and superplastic forming (SPF) presses to withstand and thrive in the high temperatures and demanding conditions associated with forming aluminum, titanium, and other high-strength materials.

During the hot forming process, both the tool and blank are heated to temperatures up to 2,000°F to increase the plasticity and elongation characteristics of the material. This introduction of heat allows the formation of high-strength materials at significantly lower tonnages when compared to cold forming operations. This is ideal since parts formed in this manner experience limited spring-back and residual stress.

While some similarities exist between hot forming and superplastic forming, the SPF process has its own unique characteristics.  SPF uses extreme temperatures in conjunction with argon gas to form high-strength alloys into complex shapes in a single step. During the cycle, the heated material is clamped between a cavity and a plate and the material is forced into the cavity by gas that is injected into the forming chamber. The resulting parts have a fine surface finish and are near net shape, eliminating the need for subsequent machining.  

Common to all Beckwood hot forming or superplastic forming machines are options to efficiently handle the extreme temperatures inherent to the process.  Platens can be fabricated from ceramics, stainless materials, or other exotic metal alloys depending on the specific application requirements.  Automated insulated door systems can be provided in order to contain the heat within the forming chamber, while also allowing adequate access during part or tool loading and unloading sequences.  

Beckwood hot forming and SPF presses provide ultimate precision, optimal temperature control and uniformity, and extreme process repeatability.  Our proprietary Active Leveling Control (ALC) also ensures bed-to-ram parallelism is maintained despite tool warpage or off-center loading.
