In industrial caster applications, engineering plastic wheel material is a popular choice. Engineering plastics include a wide range of plastics with many different types of properties well adapted to many continuous caster applications.

Materials are optional and work well

1) Operating in extremely humid and humid environments,

2) Operation at extreme temperatures,

3) Operating chemical exposure is a problem.

Engineering plastics include materials such as nylon, acetal, polycarbonate, and many others. This paper will discuss some advantages and disadvantages of industrial casters using engineering plastics.


Engineering plastics (EP) offers many benefits when used in industrial rounds of application.

1) The hardness of urethane compared to them greatly improves their ergonomic properties and crimp, thus making it easier to equip EP wheels in the operation of large carts.

2) Since exchange participants are softer steel or cast iron, they are also more likely to be on the floor, so ergonomics does not have to sacrifice floor protection.

3) Most equatorial wheels also withstand higher temperatures than polyurethane wheels. EP wheels also have a higher load capacity than polyurethane wheels with steel or cast iron hubs and do not rust.

Engineering plastics are generally RIM cast or extruded and can therefore be purchased in bar form. Generally, bars are cut to the required length and CNC machined to face the wheels into the specified file. For larger numbers of wheels, the material can be very near net shape or final configuration RIM cast.


Despite their advantages of good ergonomic design, while being easy on the floor, the use of EP wheels for industrial caster applications also has some disadvantages.

1) The EP material has a low coefficient of friction, which makes it easier for the wheels to slide at higher speeds when turning. Of course, this can be avoided by taking corners at lower speeds, or having rough floors.

2) Engineering plastics raw materials can be very expensive, especially for high performance grades although most plastics can have a reasonable price. This higher price can make EP wheels less attractive when compared to polyurethane or cast iron wheels. In some applications, only a well-designed plastic will perform to the required specifications and is worth the extra cost.

3) In applications where debris on the floor is a problem, especially metal makeup, EP wheels are easily embedded in the outer material, and it can have a significant effect on the operation of the wheels. EP wheels are best performed with a clean application of foreign body or material not lying prone on the floor or track.

In the concept of industrial casters, the company's engineering technicians have extensive experience and knowledge in the use of engineering plastics in industrial casters and wheel applications. These expert application discussions will allow you to specify the inclination or wheel that best suits your needs and application, providing you with hours of continuous service.
