What are plastic springs?

Plastic springs are components made from advanced thermoplastic materials such as Polyether Ether Ketone (PEEK), Polyoxymethylene (POM), Polycarbonate (PC), Polyetherimide (PEI), and Polyphenylsulfone (PPSU). These springs are designed to provide exceptional mechanical strength, chemical resistance, and thermal stability. They are ideal for demanding applications across various industries, including medical devices, aerospace, automotive, industrial machinery, electronics, and food processing. Each material offers unique properties, ensuring that the springs perform reliably under specific environmental conditions, such as high temperatures, corrosive substances, and repeated sterilisation processes.

Industry applications for plastic springs

Plastic screws, particularly those made from polymers like PEEK, POM, PC, PEI, and PPSU, are used across various industries due to their unique properties. In the aerospace industry, they are utilized in lightweight, high strength fastening applications that require resistance to extreme temperatures and chemicals. In the medical field, biocompatible plastic screws are used in medical devices and implants, benefiting from their sterilisation resistance and non-reactivity. In electronics, they provide electrical insulation and corrosion resistance, making them ideal for securing circuit boards and electronic components. The automotive industry uses plastic screws in engine compartments and electronic systems for their chemical resistance and lightweight properties. Additionally, plastic screws are employed in chemical processing equipment where corrosion resistance is critical, and in food processing machinery where cleanliness and non-contamination are paramount.

What are the benefits of using plastic for springs?

Using plastic for springs offers numerous benefits, particularly when made from polymers such as PEEK, POM, PC, PEI, and PPSU. These springs provide exceptional corrosion resistance, making them ideal for use in corrosive environments, and are significantly lighter than metal springs, reducing overall weight and easing installation. They offer a high strength-to-weight ratio, excellent thermal stability across a wide temperature range, and are non-magnetic, making them suitable for sensitive applications. Additionally, plastic springs provide superior electrical insulation, low friction, and wear resistance, extending their lifespan. Certain plastics, like PEEK and PPSU, are biocompatible, perfect for medical and pharmaceutical use. Their ability to be moulded into complex shapes offers design flexibility, making plastic springs a versatile and reliable choice for various demanding applications across multiple industries.

Offrono vantaggi unici che le viti metalliche non possono offrire. Sono altamente resistenti alla corrosione, il che le rende ideali per l'uso in ambienti chimici difficili dove le viti metalliche si degraderebbero. La loro leggerezza riduce il peso complessivo degli assemblaggi, un aspetto cruciale in settori come quello aerospaziale e automobilistico, dove il risparmio di peso si traduce in migliori prestazioni e risparmio di carburante. Le viti in plastica offrono anche un eccellente isolamento elettrico, evitando cortocircuiti nei dispositivi elettronici. Inoltre, hanno un elevato rapporto resistenza/peso, sono amagnetiche e possono resistere a un'ampia gamma di temperature. Queste proprietà rendono le viti in plastica essenziali per le applicazioni che richiedono durata, affidabilità e caratteristiche prestazionali specifiche che le viti in metallo non possono offrire.
