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 aerial work platforms and scissor lifts?
Yes, leaf chains are commonly used in aerial work platforms and scissor lifts for their reliable lifting capabilities and durability. Aerial work platforms and scissor lifts are equipment designed to elevate workers or materials to various heights, and they require robust and safe lifting mechanisms.
Leaf chains are well-suited for these applications because:
1. High Load Capacity: Leaf chains are capable of handling heavy loads, making them ideal for lifting platforms with varying weight requirements.
2. Strength and Reliability: In aerial work platforms, safety is paramount, and leaf chains are known for their strength and reliability, providing secure lifting operations.
3. Simple Construction: Leaf chains have a simple construction with fewer moving parts, reducing the risk of mechanical failures and simplifying maintenance.
4. Compact Design: The compact design of leaf chains allows them to fit into the limited space available in scissor lift and aerial work platform mechanisms.
5. Cost-Effective: Leaf chains offer a cost-effective solution for lifting applications compared to other more complex lifting systems.
However, it's essential to ensure that the leaf chains are regularly inspected and properly maintained to ensure safe and efficient operation. Regular lubrication and inspection of the chain and sprockets are crucial to extending the chain's lifespan and preventing unexpected failures.
In conclusion, leaf chains are a suitable and widely used choice for aerial work platforms and scissor lifts due to their strength, reliability, and cost-effectiveness. When correctly selected and maintained, they provide a safe and efficient lifting solution for various applications in construction, maintenance, and material handling industries.
What are the benefits of using a leaf chain in dock levelers and loading ramps?
Using a leaf chain in dock levelers and loading ramps offers several advantages, making them an excellent choice for these applications. Dock levelers and loading ramps are critical components in material handling, facilitating the smooth and safe transfer of goods between different heights, such as between trucks and loading docks or warehouse floors.
Here are the benefits of using a leaf chain in dock levelers and loading ramps:
- High Load Capacity: Leaf chains are known for their high tensile strength and load-carrying capacity, making them suitable for handling heavy loads typically encountered in loading and unloading operations.
- Smooth and Reliable Operation: Leaf chains provide smooth and consistent lifting and lowering movements, ensuring a reliable and controlled transfer of goods.
- Durability: Dock levelers and loading ramps are subject to frequent and heavy usage. Leaf chains' robust construction and resistance to wear and fatigue ensure a long service life with minimal maintenance.
- Compact Design: Leaf chains offer a compact and space-efficient solution for material handling applications, which is particularly important in confined loading dock areas.
- Adjustability: Leaf chains can be easily adjusted to accommodate different heights, allowing for versatile use in various loading and unloading scenarios.
Dock levelers and loading ramps require precise and secure handling to prevent accidents and ensure the smooth flow of goods. Leaf chains provide the necessary strength, reliability, and control needed for these critical material handling applications.
When designing and selecting leaf chains for dock levelers and loading ramps, factors such as load capacity, chain length, and environmental conditions should be carefully considered to ensure optimal performance and safety.
