The Advantages of Engineering Plastics over Metals

Breakthrough in Technical Performance:

Lightweight: PEEK density is only 1/3 of aluminum alloy, with equal strength. The aviation bracket reduces weight by 60% and fuel efficiency increases by 8%;
Corrosion resistance: PTFE has a lifespan of 20 times that of ultra carbon steel in 98% sulfuric acid, reducing the annual maintenance cost of chemical valves by 70%;
Function integration: 5-axis CNC one-time molding of complex flow channel structures (such as automotive turbocharger housings), reducing the welding and assembly processes of metal parts.

Full cycle cost advantage:

Processing cost reduction: PEI injection molded connectors replace copper alloy machined parts, reducing single piece costs by 45%;
Energy consumption optimization: Nylon gears replace steel gears, reducing friction losses in the transmission system by 30% and extending equipment life by 2 times.

Sustainability driven:
Circular economy: Medical grade PEEK can be sterilized and reused at high temperatures, reducing the carbon footprint of titanium alloy implants by 60%;
Design freedom: 3D printing topology optimization of plastic load-bearing components (such as drone skeletons), reducing materials by 80% compared to traditional metal structures.

Typical Alternative Scenarios:
Aerospace: PEEK replaces titanium alloy fuel pipelines, with a temperature resistance of 260 ° C and a weight reduction of 55%;
Energy: PEI insulation replaces copper-clad aluminum high-voltage connectors, increasing arc resistance by three times;
Automobile: Carbon fiber reinforced PA66 replaces steel suspension links, increasing fatigue resistance by 40%.
