Three major applications of servo thermoforming machines in the aerospace industry

The aerospace industry demonstrates the country's cutting-edge industrial strength, and the pursuit of core parts goes beyond conventional standards, pointing directly to lighter, stronger and more reliable. Lightweight is the core path of energy-saving and load-carrying aircraft, and strength and reliability are the lifeblood of flight safety. In response to this stringent demand, servo thermoforming technology has become a “breaker” in aerospace manufacturing with unique comprehensive advantages. Through the molding machine to achieve precise temperature control, pressure closed-loop adjustment and displacement real-time monitoring, cracked the high-end aviation components “precision difficult to control, quality is not stable” pain points. The following is an in-depth analysis of the servo hot press molding machine in the aerospace field of the three core applications.

Application 1: Carbon fiber composite structural parts - to realize the lightweight revolution of the fuselage and wings

Carbon fiber composites have become the core material of modern aircraft main bearing structural parts due to their ultra-high specific strength, excellent specific modulus and outstanding fatigue resistance. Servo thermoforming machine plays a key role as the core equipment for precision molding in this manufacturing process.

Typical components: wing panels, flaps, fairings; fuselage section frames, hatches; UAV fuselage and rotor blades.

Advantages of servo technology:

●Precise temperature and pressure control: The resin flow and curing reaction of carbon fiber prepreg are extremely sensitive to temperature and pressure. The servo hot press can realize multi-stage linear precision control to ensure uniform distribution of resin, eliminate dry spots, pores and other defects, and the quality of the finished product is in full compliance with aviation-grade standards.

●Excellent parallelism and stability: For the characteristics of large area and complex shape of aviation components, the servo motor-driven slider realizes ultra-high parallelism of the table surface and ensures uniform distribution of pressure over the whole area, which ensures consistent thickness and stable molding of the components.

●Repeatability and data traceability: The pressure-time and temperature-time curves are accurately recorded and reproduced throughout the process, providing solid data support for product quality traceability and process optimization, and helping to continuously upgrade the production process.

Application 2: Engine core components and blades - building a strong defense of performance and reliability under extreme working conditions

Aero-engine as the “heart” of the aircraft, its internal components need to withstand high temperature, high pressure, high speed of extreme working conditions for a long time test. With precise molding control capability, servo hot press has become the core equipment for manufacturing key high-temperature resistant parts of the engine.

Typical components: engine honeycomb sealing rings; heat insulation tiles, firewalls; part of the composite low-pressure turbine blades

The advantages of servo technology are reflected:

●Near-net forming to reduce cost and improve quality: For complex structural components such as honeycomb sealing rings, the entire forming process is precisely controlled to minimize the subsequent machining allowance, which not only reduces the manufacturing cost, but also preserves the original structural properties of the material and avoids the influence of secondary processing on the accuracy of the components.

●Precise control of resin distribution: For high-temperature parts that require resin impregnation, precise pressure control ensures that the resin content is just right, which not only ensures performance, but also avoids waste and shortcomings in performance caused by uneven resin.

●Suitable for high-temperature special materials: together with the special heating system, the servo hot press is able to stably process advanced high-temperature-resistant composite materials such as polyimide, which meets the demanding requirements of engine peripheral parts.

Application 3: Aircraft interior trim - building a safe, comfortable and lightweight cabin space

Aircraft interior parts not only directly affect the passenger experience, but also need to strictly meet the mandatory aviation standards of flame retardancy, low smoke toxicity and lightweight. Servo thermoforming machine has become the core equipment for the mass production of high-performance interior parts due to its efficient and stable processing characteristics.

Typical parts: luggage racks, partitions; kitchen/toilet module panels; seat backs, small table boards.

The advantages of servo technology are reflected:

● High-efficiency production and fast cycle: Servo motor direct-drive design realizes instant response to start and stop, completely eliminating the action delay of the traditional hydraulic system, and greatly shortening the cycle of pressure boosting, pressure holding and mold opening, precisely matching the rhythm of mass production of interior parts.

● Energy-saving and environmentally friendly green manufacturing: The holding pressure stage consumes only a small amount of energy to maintain pressure, which reduces energy consumption by up to 60% compared with the continuous high energy consumption of traditional hydraulic stations, perfectly matching the green development concept of the aviation industry.

● Clean and low-noise optimization of production environment: no hydraulic oil leakage, significant reduction in operating noise, creating a clean, environmentally friendly, low-noise and friendly operation scene for the production workshop, reducing workshop operation and maintenance costs.

Why must the aerospace field choose servo hot press molding machine?

Beyond traditional hydraulic pressure: completely get rid of the inherent pain points of traditional hydraulic presses, such as “oil leakage, high consumption and low efficiency, and poor control accuracy”, and realize the leapfrog upgrade of molding equipment from roughness to precision.

Data-driven quality: The process parameters of the whole process of press molding can be accurately recorded, traced and reproduced to build a standardized and controllable precision production system, ensuring that every product meets the stringent aviation-grade standards.

Enabling innovative materials: Providing a highly adaptable molding platform for next-generation aerospace innovative materials, such as thermoplastic composites, to help aerospace components achieve performance breakthroughs in material upgrades.
