The weight of plastic fasteners is approximately 30% of that of metal, which can significantly reduce the overall weight of the equipment and is suitable for fields such as aerospace and automotive where weight sensitivity is a concern.
Materials such as PEEK and PVDF have excellent resistance to chemical corrosion and can be used for a long time in environments with strong acids and strong bases. The PVDF material can last for more than ten years in corrosive workshops.
Materials such as nylon do not conduct electricity and are widely used for fixing PCB circuit boards to avoid short-circuit risks.
Suitable for electromagnetic compatibility requirements of precision instruments (such as optical equipment).
Some engineering plastics (such as POM) can maintain their performance within the range of -30℃ to 120℃, while fluoropolymers (such as PTFE) have a temperature resistance of up to 260℃.
Exhibits minimal deformation under long-term loading, making it suitable for scenarios with high durability requirements such as automotive interiors.
Suitable for food contact or medical equipment (such as an alternative solution of 316L stainless steel).
Compared to metal parts, plastic fasteners have lower production costs in mass production and do not require rust prevention treatment.
Used for the fixation of body, interior and exterior trims, chassis and other components, such as push-in fasteners (anchor-type fasteners, Christmas tree fasteners) to achieve rapid assembly, and plastic nuts in combination with bolts to complete detachable connections.
Fasteners made of PEEK material (such as bearings and gears) can reduce weight by 40%, and are suitable for battery modules and motor components of new energy vehicles.
The plastic end bolts are both detachable and waterproof, and are suitable for engine compartments or electronic and electrical modules.
Alternative metal fasteners are used in humid environments (such as basements, coastal buildings) to avoid rusting problems.
Plastic cable ties are used for cable management or temporary structure fixation, providing flexible solutions in disaster relief and event setup.
PEEK material is used for artificial spinal columns, joints and other implants. It has better biocompatibility than metals and does not affect medical imaging examinations.
Aerospace: PEEK fasteners are resistant to high temperatures and lightweight, and are used in aircraft structures or cabin components.
Semiconductor Manufacturing: Anti-static PEEK profiles are used for precision components such as wafer carriers.
Plastic fasteners offer several key advantages over metal alternatives, including significantly lower weight (approximately 30% of metal), excellent corrosion resistance, electrical insulation, non-magnetic properties, and lower production costs in mass manufacturing. They also eliminate the need for rust prevention treatments.
PTFE (polytetrafluoroethylene) fluoropolymer is the top choice for high-temperature environments, offering temperature resistance of up to 260℃. PEEK is also an excellent option for high-temperature and high-performance applications, particularly in aerospace and semiconductor industries.
Yes. Plastic fasteners, especially those made from PEEK material, are widely used in medical devices such as artificial spinal implants and joints due to their superior biocompatibility. They do not cause metal contamination, making them ideal for food-contact equipment and medical applications as an alternative to 316L stainless steel.
Absolutely. Materials such as PVDF and PEEK provide excellent resistance to strong acids, strong bases, and chemical corrosion. PVDF fasteners can last more than ten years in corrosive industrial workshops, and plastic fasteners are an ideal replacement for metal in humid environments such as basements or coastal buildings.
Plastic fasteners are used across a wide range of industries including automotive (body trims, chassis, EV battery modules), aerospace (aircraft structures and cabin components), medical (implants and surgical devices), semiconductor manufacturing (wafer carriers), construction (humid environments), and general electronics (PCB board fixation).
High-performance engineering plastics such as POM and PEEK exhibit excellent creep resistance, meaning they show minimal deformation even under prolonged mechanical loading. POM maintains stable performance within a temperature range of -30℃ to 120℃, making it well-suited for demanding applications like automotive interiors and industrial assemblies.
