Brief Introduction to Vacuum Forming Technology
Vacuum forming is a type of thermoforming process. It heats and clamps the plastic sheet and the mold. The plastic sheet softens and reaches a plastic state that can be processed. The mold built into the vacuum forming machine lifts up and fits the softened sheet, forming a three-dimensional product through the mold. The cooling equipment above blows air, and the plastic sheet cools down while maintaining the shape of the mold, thus completing the production process of the vacuum formed product.
Compared with other plastic processing technologies, vacuum forming can produce simple or complex products at a relatively low cost and is widely used in various fields. Especially compared with the injection molding process, which is also widely used on the market, the cost of the mold is only one-tenth of that of the injection molding process, and the mold production cycle is reduced by about 85% compared with the injection mold production cycle. At the same time, the vacuum forming mold is relatively simple and can be modified during the product development stage or later, so it has great advantages in prototyping and mass production of products.
Relevance of Vacuum Forming in the Aerospace Industry
Over the years, vacuum forming has become increasingly popular and now allows us to produce some plastic parts for aerospace, drones and helicopters. We can not only manufacture individual parts, but also provide a comprehensive assembly service, including all the internal structures of the aircraft. Vacuum formed plastics are lightweight, durable, flexible in design, relatively low in cost, and have a fast production cycle.
1. Plastic parts produced by vacuum forming can replace heavier metal parts without affecting the durability and performance of the aircraft.
2. The vacuum process itself has excellent design flexibility. Aerospace parts generally require a lot of product testing during the development phase. For complex aerospace parts, the difficulty of modification is relatively low. Low mold costs are also very suitable for the rapid iteration of aerospace parts.
3. Aerospace products generally have high material requirements. We have two large sheet extrusion machines, providing high-performance PC, ABS, and Kydex materials to meet the strict regulatory standards of the aerospace industry.
Why Plastic Components Are Essential in Aerospace
Plastic parts are essential in aerospace because they offer unique material advantages that significantly improve aircraft performance, durability and cost-effectiveness. These benefits include reduced weight and improved fuel efficiency, superior durability and environmental resistance, compliance with fire, smoke and poison (FST) standards, noise reduction and improved passenger comfort, design flexibility and customization capabilities, reduced maintenance and operating costs, as well as sustainability and recyclability. The lightweight properties of plastic allow aircraft to consume less fuel and produce fewer emissions while increasing range and lowering operating costs. High-performance plastics such as polyetherimide (PEI) and Kydex offer excellent heat and chemical resistance and are suitable for harsh environments such as engine compartments.
Aerospace-grade specialty plastics offer excellent safety properties and can be used directly in cabin components without additional processing, meeting strict industry standards. These plastics also have excellent soundproofing properties, greatly improving the passenger experience. Its unique plasticity allows manufacturers to efficiently produce a variety of customized parts to meet the needs of different machine models. Due to their excellent corrosion resistance, plastic components significantly reduce maintenance frequency and extend their service life, thus reducing overall operating costs. It’s worth mentioning that many plastics used in aviation are recyclable, which not only reduces waste but also helps lower the carbon footprint of the entire industry. To sum up, plastics have demonstrated a full range of advantages in the aerospace field, from improving performance to promoting environmental sustainability, making them an indispensable key material in the manufacturing process of modern aircraft.
Common Plastics Used for Aerospace Vacuum Forming
Aircraft Windshield
Polycarbonate (PC): High heat resistance, optical clarity for windows or lenses
Aircraft Table Assemblies
Acrylonitrile Butadiene Styrene (ABS): High impact resistance, lightweight
Aircraft housing
Kydex: Flame retardant, used in interior panels and cockpit components
Drone Housing
Polyvinyl Chloride (PVC): Chemical and corrosion-resistant
Applications of Vacuum Formed Plastic Components in Aerospace
Internal Aircraft Cabin Interiors
This is an Aircraft and it’s a top secret in Ditai. All I can tell is the whole crafts’ covering are made by the Vacuum Forming Process. And then after the complex gluing, assembly, painting, and silk screening, with some hardware accessories to support, making it safe and at the same time very beautiful!
Single-Pilot Aerial Vehicle Housing
This is a single-pilot flight project from Singapore, the main purpose of which is to facilitate travel and relieve some of the traffic pressure. The red color of the fuselage is shown by the later painting and these products also require very complicated gluing and assembly! But we are so proud that we can make it!
Drone Housing For Agricultural Use
This is an agricultural drone housing. With the development of modern technology, in some places, the spray of pesticides has moved to be carried out in the air. The benefits of using drone for spraying are that human body can be protected from harm, avoiding repeated or less spraying, improving the utilization of pesticides wgile reducing the time and greatly reducing the time of operation!
Quality Control and Compliance Standards
In the aerospace industry, strict quality control and regulatory compliance are the cornerstones to ensure the safety, reliability and performance of aircraft components. Vacuum-formed plastic parts must meet strict aerospace certification standards, such as ISO 9001 Quality Management System and AS9100 Aerospace Manufacturing Process Specification. These standards ensure that each part produced meets the precise requirements of high-performance applications.
Aerospace parts are also subject to strict fire, smoke and toxicity (FST) regulations, such as FAR 25.853. This is particularly important for plastic parts in aircraft interiors, including seat backs, cabin panels and overhead bins. The materials used must undergo rigorous testing to ensure low flammability, minimal smoke emissions, and no toxic byproducts when burned.
Traceability is another key aspect of quality control. Each production batch must be carefully documented and traceable to the original material. This is not only critical for regulatory audits, but also facilitates product recalls if problems arise. In addition, comprehensive quality checks are performed during the production process, including dimensional inspections, surface finish assessments, and pressure testing to ensure that parts meet precise tolerances and performance requirements.
At DitaiPlastic, we have not only obtained ISO 9001 quality management system certification, but also AS9100 certification specific to the aerospace industry. At the same time, our ERP digital management system plays a key role in tracking production data, managing quality inspections, and maintaining compliance records. Every step will be uploaded and recorded, from raw materials to finished products, to fully control the quality of the product.
