Key points for selection

When purchasing rubber wheels, pay attention to the following points:

1. The weight that the wheels need to bear, and the purchased wheels should be greater than this weight to increase the service life of the wheels;

2. The usage site of wheels, smooth wheels with light glue, unsmooth wheels with thread glue, and grooved iron cores;

3. For lightweight wheels, choose light rubber wheels, while for heavy ones, choose wire rubber wheels; For slotted iron cores;

4. The choice of quality requires wheels to have elasticity and hardness, otherwise they are prone to peeling and peeling, making them cheap to buy and expensive to use. The load-bearing components must have a slotted iron core and wire adhesive, which will ensure long service life and low cost. No matter what type of wheel lacks elasticity and hardness, its quality will not be good.

Basic characteristics of rubber wheels

1. When rubber products are formed, they are subjected to high pressure compression, and due to the inherent cohesion of the elastomer, they cannot be eliminated. When forming and leaving the mold, they often experience extremely unstable shrinkage (the shrinkage rate of rubber varies depending on the type of rubber), which must take a period of time before it can be stable and stable. So, at the beginning of a rubber product design, regardless of the formula or mold, it is necessary to carefully calculate the fit. If not, it is easy to cause unstable product size and low product quality.

2. Rubber belongs to the category of thermosetting elastomers, while plastic belongs to the category of thermosetting elastomers. Due to the different types of sulfides in rubber, there is also a considerable difference in the temperature range of its molding and curing, and it can even be affected by climate change and indoor temperature and humidity. Therefore, the production conditions of rubber products need to be adjusted appropriately at any time. If not, there may be differences in product quality.
