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 are fastening components made from engineering plastics such as PEEK, PVDF, nylon, POM, or PTFE. Unlike metal fasteners, they are significantly lighter (approximately 30% of the weight of metal), corrosion-resistant, electrically non-conductive, and do not require rust prevention treatment, making them ideal for specialized industrial applications.
Fluoropolymers such as PTFE offer the highest temperature resistance among common plastic fastener materials, withstanding temperatures up to 260℃. For moderate temperature ranges (-30℃ to 120℃), POM engineering plastic is a reliable and cost-effective choice.
Yes. Plastic fasteners produce no metal contamination, making them suitable for food contact equipment and medical devices. PEEK material, in particular, is widely used in medical implants such as artificial spinal columns and joints due to its excellent biocompatibility and non-interference with medical imaging.
Absolutely. Materials such as PVDF are specifically designed to resist strong acids and strong bases, with a service life of over ten years in corrosive workshops. Plastic fasteners are also ideal replacements for metal fasteners in humid environments like basements or coastal buildings where rust is a concern.
In mass production scenarios, plastic fasteners typically have lower manufacturing costs than metal alternatives. They also eliminate the need for additional rust prevention treatments, further reducing long-term maintenance and operational expenses.
PEEK fasteners are widely adopted across multiple high-demand industries including aerospace (aircraft structures and cabin components), new energy vehicles (battery modules and motor parts), semiconductor manufacturing (wafer carriers and precision components), and medical devices (implants and surgical instruments) due to their outstanding strength, thermal stability, and chemical resistance.
