heavy duty casters for tool cabinets-- different casters have different materials and formulas. Even if the same caster has different colors, its materials and formulas are also different. There are many kinds of castor materials, which also gives some businesses a big gap. The substitution of materials and the abuse of low-quality materials have completely disrupted the whole market. The following briefly introduces several common identification methods, heavy universal caster materials.
Incineration method of heavy duty casters for tool cabinets material identification:
1. Polyurethane: easy to burn, light white smoke is generated during incineration, easy to melt, and does not affect odor, viscosity and filamentity
2. Polyvinyl chloride (PVC): easy to burn, thick black smoke, influence of odor, no sticky line, and black toner on the surface after combustion
3.Nylon wheel: not easy to burn. When burning, there is the smell of burning hair. After burning, the outer surface is foam and sticky.
4.High temperature nylon (PA): the combustion conditions are the same as those of PA material, but there is white powder outside after combustion.
5. Polypropylene: easy to burn, with slight plastic smell. When burning, the outer surface melts evenly and has sticky threads.
6.Thermoplastics: Thermoplastics burn with a heavier smell and thicker smoke.
7. The color of nylon wheel products is light yellow or milky white. Nylon is a kind of polymer material, so it has high mechanical strength and can reach the strength of metal materials. There is a very simple evaluation method, which is to hit it with a hammer and test its hardness. If the wheel you buy is hard enough, it is a nylon wheel, and if it is very soft, it is a plastic wheel.
8. Plastic castors are the same as nylon castors in appearance and color. If you scratch the wheel on white paper, the plastic wheel will leave deep scratches, while the nylon wheel will not.
9. The quality of plastic wheels is very poor. It can only be used for light equipment. There are many problems with plastic wheels of large equipment.
10. The service life of plastic wheels is also shorter than that of nylon wheels.
The diversity of heavy duty casters for tool cabinets materials and products makes it difficult for everyone to identify these materials. However, as long as we carefully understand and analyze these materials, you will certainly get something. The authenticity of your casters can also be recognized. The price of nylon is more than twice that of plastic, so there is a big difference between the two. Plastic castors are very similar to nylon wheels in color and appearance, or even exactly the same. Of course, not only are plastic and nylon wheels mixed with fish and dragon balls, but many caster manufacturers also do so to reduce costs. Based on the consideration of cost saving, some dealers only pay attention to price rather than quality. Plastic wheels can be used for some light-weight machines, but for some machines with high load, plastic wheels cannot be used.Therefore, there are many quality problems, causing potential safety hazards and increasing operating costs.
