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 -30â to 120â, while fluoropolymers (such as PTFE) have a temperature resistance of up to 260â.
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 reduced weight (approximately 30% of metal weight), excellent corrosion resistance, electrical insulation, non-magnetic properties, and lower production costs in mass manufacturing. They also eliminate the need for rust prevention treatments.
For high-temperature applications, fluoropolymers such as PTFE offer temperature resistance of up to 260â, making them ideal for demanding thermal environments. Engineering plastics like POM are suitable for moderate temperature ranges of -30â to 120â, covering most industrial and automotive applications.
Yes. Plastic fasteners, especially those made from PEEK material, produce no metal contamination and are suitable for food contact equipment and medical devices. PEEK is also used in implants such as artificial spinal columns and joints due to its superior biocompatibility and its non-interference with medical imaging examinations.
Materials such as PVDF and PEEK exhibit excellent resistance to strong acids and strong bases. PVDF fasteners, for example, can last for more than ten years in corrosive industrial workshops, making them a reliable long-term solution in chemical processing, coastal construction, and other harsh environments.
Absolutely. PEEK fasteners are widely used in aerospace applications due to their high-temperature resistance and lightweight properties, suitable for aircraft structures and cabin components. In semiconductor manufacturing, anti-static PEEK profiles are used for precision components such as wafer carriers, meeting the strict requirements of cleanroom environments.
In the automotive industry, push-in fasteners (such as anchor-type and Christmas tree fasteners) are commonly used for rapid assembly of body panels, interior and exterior trims, and chassis components. PEEK-based fasteners are also used in new energy vehicle battery modules and motor components, offering up to 40% weight reduction compared to metal equivalents.
