Superplastic molding machine

Dalian Tianyi can equip the production of superplastic molding machines for aluminum, titanium and other high-strength materials related molding equipment. During the thermoforming process, both the mold and the blank are heated to high temperatures of up to 950°C to improve the plasticity and elongation properties of the material. This introduction of heat allows high-strength materials to be formed at significantly lower tonnage compared to cold forming operations. This is ideal because the components formed in this way are subjected to limited springback and residual stress. While there are some similarities between press hardening and superforming, the TSPF process has its own unique characteristics. TSPF uses extreme temperatures combined with argon gas to form high-strength alloys in one step, forming complex shapes. During the cycle, the heated material is sandwiched between the cavity and the plate. The material is then pressed into the cavity by injecting argon gas into the forming chamber. The resulting parts have a fine surface finish and a near-net shape, eliminating the need for subsequent machining.

All Tianyi equipped thermoforming or supermolding machines are the choice for the extremely high temperatures inherent in the effective handling process. Depending on the specific application requirements, flat panels can be manufactured from ceramic, stainless steel or other special metal alloys. Automated insulating systems can be provided to efficiently contain heat in the forming chamber, while also allowing sufficient access during part or tool loading and unloading. Dalian Tianyi can be equipped with thermoforming and TSPF presses that provide precision, optimal temperature control and uniformity, and extremely high process repeatability. 

The advantage of TSPF superplastic forming, it only requires one mold, one core or one cavity. Ability to manufacture designs with freely combinable surfaces. Complex shapes that are difficult to form can be formed through the cold forming process, with low environmental impact and low noise.

Superplastic molding process:

Titanium alloy superplastic forming generally adopts the mold furnace heating method. That is, put the mold into the furnace for high temperature heating, until heated to the temperature of superplastic forming (700 °C ~ 1000 °C), and then put the titanium alloy raw material into the mold, relying on the heat conduction of the mold to heat the titanium alloy raw material to the superplastic forming temperature, there is an inert gas (such as argon) that requires a certain pressure during the process to prevent the titanium alloy from oxidizing and hydrogen absorption at high temperature, and the inflation rate should be slow, and the variable air pressure time curve is used to achieve the required molding speed and part thickness.
