Product Description
I. Core Application Areas
The frame-type composite material hot press is a critical piece of equipment for large-scale, high-tonnage, mass-production composite molding. Combining the "high rigidity of its frame structure," the "efficiency of multi-layer hot press plates," and the "reliability of precise control," it is widely used in the following high-end industries:
1. Aerospace sector (core high-value applications)
The frame-type structure boasts superior resistance to eccentric loading (with rigidity outperforming the four-column type), making it ideal for manufacturing large-sized load-bearing components such as aircraft wing skins, fuselage sections, satellite supports, and rocket fairings. Multi-layer hot press molds enable the high-volume processing of carbon fiber prepregs or composite material blanks, ensuring both dimensional accuracy—within ±0.05 mm—and exceptional mechanical properties, including tensile strength ≥500 MPa and stiffness ≥20 GPa. This capability perfectly meets the aerospace industry’s extreme demands for "lightweight yet ultra-strong" materials. For instance, a specific model of aircraft wing component requires forming using a 1,500-ton frame-type multi-layer hot press machine, capable of producing two parts per layer while achieving an impressive hourly output of 8 to 10 units.
2. Automotive Manufacturing Industry (Demand for Scalable Lightweight Solutions)
Addressing the core automotive need for "weight reduction and energy efficiency," frame-type multi-layer hot presses are used to mass-produce composite structural components—such as body frames, battery pack housings, door panels, and chassis parts. This frame-based design delivers stable, high-pressure capabilities (up to 2,000–5,000 tons), ensuring thorough compounding of carbon fiber or glass fiber with resin matrices while preventing delamination or air bubbles. Additionally, the multi-layer configuration (4–12 layers) significantly boosts production capacity—achieving 3 to 5 times higher output compared to single-layer machines—thus meeting the automotive industry's demand for "scalable manufacturing." For instance, a certain new-energy vehicle manufacturer employs a 10-layer frame-type hot press capable of producing 30 battery pack housings per hour.
3. Sports Equipment Manufacturing (High-End Customization Needs)
The framework-style structure offers precise control capabilities—pressure can be maintained within ±0.1 MPa, and temperature within ±3°C—making it ideal for manufacturing high-end sports equipment such as carbon-fiber bicycle frames, golf clubs, skis, and tennis rackets. Multi-layer hot-pressing plates allow simultaneous molding of multiple components (e.g., producing two bicycle frames per layer), significantly reducing per-unit production costs. Meanwhile, the exact temperature and pressure control ensures consistent mechanical properties across all products—such as achieving an impact-resistance tolerance of less than 5% for bicycle frames—thus meeting the tailored needs of professional athletes.
4. Industry and New Energy Sector (High-Demand for Large-Scale, High-Strength Applications)
The frame-type structure ensures stability—free from swaying or uneven loading—making it ideal for producing large-scale industrial composite components such as wind turbine blades, 5G base station antenna domes, high-pressure vessels, and tunnel-boring machine cutters. Its multi-layer design (6–12 layers) significantly boosts production efficiency; for instance, carbon-fiber skins for wind turbine blades can be manufactured at a rate of 4 to 6 pieces per hour. Moreover, the use of high-temperature, high-pressure conditions—ranging from 200–300°C and pressures of 1,000–3,000 tons—guarantees that the final components achieve exceptional strength, with tensile strengths of ≥300 MPa in applications like wind turbine blades. This meets the growing demand in the new energy and industrial sectors for "large dimensions combined with ultra-high reliability."
II. Core Features (The Combined Advantage of a Framework-Based and Multi-Layered Approach)
1. Framework Structure: High Rigidity and Resistance to Lateral Loads
It adopts a rectangular frame/Gantry frame structure (welded from steel plates), offering excellent overall rigidity and superior resistance to eccentric loading—up to 20%-30% higher than four-column types. This design is ideal for handling high-tonnage presses (1000–5000 tons) and large-sized products, such as wind turbine blades exceeding 10 meters in length. The frame-style construction ensures smooth slider movement without any shaking, effectively preventing mold damage or workpiece deformation caused by uneven loading.
2. Multi-layer Design: Efficient Mass Production with Uniform Heat Distribution
Equipped with 4-12-layer hot press plates (each layer features independent temperature control), this machine can simultaneously apply pressure and heat to multiple composite material preforms—such as carbon fiber prepregs and glass fiber-reinforced plastics. Its production capacity is 3 to 5 times higher than that of single-layer machines. The hot press plates are precision-ground using imported tool steel, ensuring minimal thermal deformation (<0.1mm). Thanks to PID-based intelligent temperature regulation, the system allows for precise adjustments from room temperature up to 300°C, with a temperature accuracy of ±3°C per layer. This ensures uniform heating across all workpieces, preventing uneven resin flow or curing defects caused by temperature variations.
3. Composite Material Compatibility: High-Temperature, High-Pressure Conditions and Defect Control
Addressing the **"resin flow + fiber orientation"** requirements for composite materials such as carbon fiber and glass fiber, we offer:
- High-Temperature Control: Temperature can reach 200–300°C (suitable for curing temperatures of epoxy resins, phenolic resins, and more), with an accuracy of ±3°C.
- High-pressure output: Up to 1000–5000 tons (ensuring resin fully fills fiber gaps, preventing bubbles or delamination);
- Resin Loss Control: By implementing multi-stage pressure settings—such as "pre-pressure, main pressure, and holding pressure"—resin loss during the molding process is minimized (resin content error < 2%).
4. Intelligent Control: Servo Closed-Loop System with Process Flexibility
Equipped with a servo closed-loop control system, the equipment enables precise control of pressure (±0.1 MPa), temperature (±3°C), and displacement (±0.02 mm). It supports flexible, multi-segment settings for both pressure and stroke, such as "fast descent—slow pressurization—pressure-holding curing—rapid return," making it suitable for various composite material molding processes—for instance, the "heating → pressurization → curing → cooling" sequence used for carbon fiber prepregs. Additionally, some models can store over 100 sets of process parameters, including mold numbers, temperature profiles, and pressure curves. When switching between products, operators simply recall the corresponding program, significantly reducing mold-change time by more than 30%.
5. Energy Efficiency and Safety: Balancing Performance with Protection
- Energy efficiency: The servo system only performs work when the cylinder is in operation, eliminating overflow losses. This results in energy savings of up to 30%-50%, while also maintaining low operational noise levels (below 70 dB).
- Safety: Equipped with a highly sensitive through-beam safety light curtain (covering the equipment’s opening area), three-sided guardrails, dual-hand operation buttons, and an emergency stop button to ensure operator safety—and prevent injuries or equipment damage caused by accidental misoperations.
