Engineered for challenging materials like titanium, aluminum, magnesium, and superalloys, the Superplastic Forming Machine from Shuntian Equipment delivers a high-performance thermoforming solution beyond the reach of conventional stamping.
By integrating precision temperature control, high-pressure gas forming, rapid cooling, and automated operation, it consistently produces thin-walled, deep-cavity components with complex ribbed structures. This technology is a critical enabler for weight reduction and performance gains in aerospace and automotive lightweighting.
PRODUCT DESCRIPTION
1. Exceptional Temperature Uniformity – The Foundation of Precision Forming
A multi-zone independent heating system, combined with high-temperature sealing technology and radiant heat circulation, delivers temperature uniformity of up to ±5°C across the die workspace. This precision eliminates localized overheating, unlocks the full superplastic potential of the material, and ensures consistent mechanical properties across every component.
2. Hybrid Pneumatic & Servo-Hydraulic Forming for Complex Geometries
High-precision proportional valves enable stepped pressurization, pulse holding, and closed-loop pressure control. Whether running constant-pressure slow forming or variable-pressure variable-rate processes, the system handles it seamlessly—ideal for filling intricate features like ribs and dimples in TA15, TC4, and other titanium alloys.
3. Advanced Blank Holding & Sealing – Stability Under Extreme Conditions
●High-Temperature Blank Holder Control: Servo-hydraulic actuators provide precise, adjustable force during forming—preventing wrinkling while allowing optimal material flow.
●Leak-Tight Sealing: Patented high-temperature seals prevent argon or other protective gases from escaping under extreme pressure and heat, reducing costs and ensuring process reliability.
4. Intelligent Process Database – One-Touch Operation
●Built-In Expert System: Preloaded with superplastic forming parameters for common materials (e.g., TC4 titanium, 5083 aluminum). Simply input material type and thickness; the system automatically sets heating curves, pressure profiles, and dwell times.
●Full Traceability: Real-time recording of temperature, pressure, and displacement curves. Data can be stored or exported to meet aerospace-grade quality traceability requirements.
1. Tooling & Heating: Install the die, activate multi-zone heating, and ramp to superplastic temperature.
2. Blank Loading: Robot or operator places the cut sheet onto the lower die; upper die closes and applies blank holder force to seal the cavity.
3. Superplastic Forming: Inert gas (argon/nitrogen) is introduced following a preset pressure-time curve. Back-pressure control (optional) prevents excessive thinning.
4. Cooling & Part Removal: Rapid cooling system activates; finished part is removed—cycle complete.
●Aerospace: Aircraft doors, fairings, engine heat shields, missile fins, casings
●Automotive: Titanium/aluminum alloy door inners, B-pillars, wheel housings
●Rail & Defense: Complex curved skins, instrument housings
