Product Description

Industry heavy duty injection molding POM-C Derlin Acetal plastic flexible transmission convey leaf chain

POM (Polyformaldehyde)
 
POM (Full-name: Polyformaldehyde), is a engineering plastics of non-side-chain, high density, high crystalline and linear polymer, which is praised “Plastic Steel”, and has comprehensive excellent performances, such as: wear-resistance, high hardness, anti-impregnant, good rigidity (Tensile modulus of elasticity), chemical stability, isolation resistance and dimensional stability. POM has widely applied in Automobile industries, electronic and electric products, commodity, pipeline & fittings, exact apparatus and so on, which can be instead of the bronze, Zinc, tin and other metals.
 
Except POM-H, is often copolymerized with ethylene oxide together, in order to avoid the melting of POM material in the high temperature. POM-H has the better performances than POM-C in its high crystalline, mechanical strength and rigidity. And POM-C has the better performances than POM-H in its low melting point, temperature stability, fluxion characteristic and machining capability.
Father more, POM-H+PTFE, which is made from the Delrin POM Resin that maxed Teflon fiber symmetrically, has the low co-efficient of frication, good lubrication, wear-resistance, non-creepage resistance.
 
Automobile industries: POM has a large application in car industries, because the mechanical parts made by POM, which has the advantages of high mechanical strength, high hardness, good wear-resistance, low co-efficient of friction, easy to maintain, reducing cost and so on, can be used in cars instead of coppery half stalk and planet gear. It not only saving copper materials, but also improving service life. At the engine fuel system, components for hose valves and case cover of radiator, cooling fluid’s standby case, water valve, oil box’ cover, pump impeller, shell of gasification machine and accelerator pedal and so on.
 
Electronic and electric Industries: because of its lower power consuming, high dielectric strength and insulation resistance and electronic arc resistance,  POM has widely applied in electronic and electric Industries, such as: shell of electronic spanner, shell of electronic scissors, shell of coal drilling machine ,handle of switch, parts also for phone, wireless recorder, video tape recorder, television, computer, electrograph, calculagraph, bracket of recorder tape and so on.
 
Agricultural machine: part of manual sprayer, joint and transport part of seeder, parts of milk machine, shell of irrigation and drainage, valve, joint and bush of water and so on.
 
Other field:
Pharmacy & packing Machine: transporting screw, planet gear, gear bar, chain wheel and cushion bar and so on.
Construction industries: water tap, window frame, wash pot, water tank, pulley for portiere, shell of water meter and tie-in of water pipe.

Can leaf chains be used in hydraulic and pneumatic lifting systems?

Yes, leaf chains can be used in hydraulic and pneumatic lifting systems. Leaf chains are known for their high-strength and durability, making them suitable for various heavy-duty lifting applications, including those involving hydraulic or pneumatic systems. Here are some reasons why leaf chains are compatible with these lifting systems:

  • Strength: Leaf chains are designed to withstand high loads and forces, which makes them ideal for hydraulic and pneumatic lifting systems that require substantial lifting capacity.
  • Reliability: Leaf chains have a simple design with fewer moving parts, reducing the risk of failure in lifting systems where reliability is crucial.
  • Compactness: Leaf chains have a compact profile, making them suitable for applications with limited space, such as hydraulic and pneumatic lifting systems.
  • Wear Resistance: Leaf chains are manufactured using high-quality materials and heat-treated components, enhancing their wear resistance and longevity even under demanding conditions.

However, it’s essential to consider the specific requirements of the lifting application, including the load capacity, speed, and environmental factors. Regular maintenance and lubrication are also vital to ensure the optimal performance and longevity of the leaf chain in hydraulic and pneumatic lifting systems.

How do leaf chains handle extreme weather conditions such as rain or snow?

Leaf chains are designed to perform well in various environmental conditions, including rain and snow. However, their ability to withstand extreme weather depends on the material and surface treatment used in their construction.

Most leaf chains are made from high-quality alloy steel, which offers good resistance to corrosion and adverse weather conditions. Additionally, manufacturers may apply various surface coatings or treatments to enhance the chains’ durability and protection against moisture.

Here’s how leaf chains handle extreme weather conditions:

  • Corrosion Resistance: Leaf chains made from stainless steel or treated with corrosion-resistant coatings are better equipped to handle prolonged exposure to rain or snow. These chains are less likely to rust or corrode, ensuring their longevity in challenging weather environments.
  • Lubrication: Regular and proper lubrication of leaf chains can help protect them from moisture and reduce friction, even in wet conditions. Lubrication prevents the chains from seizing up and helps maintain their smooth operation.
  • Sealed Joints: Some leaf chain designs feature sealed joints or bushings that help keep contaminants, such as dirt, water, or snow, out of the chain’s interior. This sealing minimizes the chances of foreign particles causing wear and damage to the chain components.

It is important to note that while leaf chains can handle rainy or snowy conditions, they may require more frequent maintenance in such environments. Regular inspections, cleaning, and lubrication will help ensure optimal performance and extend the lifespan of the chains.

When selecting leaf chains for applications exposed to extreme weather, it’s essential to consider the environmental factors and consult with chain manufacturers or experts to choose the most suitable chain type and material for the specific weather conditions the chains will be exposed to.
