When the industrial caster appears degumming, burst how should do? During the period of visiting customers, I met a customer who made mechanical equipment. He told me that they had used a batch of industrial casters before. During the use of these wheels, a large number of castor tires burst and other phenomena occurred. They could not be used at all, and they had to buy a new batch later. After hearing this case, I had a detailed understanding of its use, as well as a parameter of various aspects of this industrial caster, as well as a situation of the company. Only then did I know that the industrial caster could not meet the requirements of load-bearing driving. Because the customer's equipment is often mobile and push type, once the load driving time is too long, it is easy to appear degumming or bursting phenomenon.
Generally speaking, if the industrial casters used by customers are often moving and pushing, then we should carry out load walking test on the samples of the industrial casters before leaving the factory, or if the customers have special requirements, we will carry out the relative test, so as to prevent defective products and improve the quality of industrial casters. Therefore, an industrial caster manufacturer is very important in product quality inspection Key. When the industrial caster appears degumming and bursting, the inspection of product quality should be strengthened.
Wear resistance test of industrial caster under load
1、Test purpose: to test whether the industrial casters meet the requirements and ensure the product quality.
2、Ambient temperature: no special environmental requirements, ordinary indoor environment is OK.
3、Testing instrument: caster multifunctional testing machine.
4、Walking obstacle height: the soft wheel is 3% of the wheel diameter, and the hard wheel is not. The obstacle and the wheel travel direction are 45 ° angle, and the two obstacles are placed alternately.
5、Test timing: complete cooling after single round injection molding, bracket riveting and assembly.
6、Tread hardness: TPU (85a-100a), TPE / TPR (65a-90a)
7、Test standards: mainly according to customer standards.
8、All products randomly sampled in normal production shall walk continuously for 5 hours at 1.2 times of the conventional load capacity; the incoming materials shall be tested according to the load of 1.2 times of the conventional load capacity and continuously walk for 8 hours, and the tires shall be free from cracks, spalling and local excessive wear; all parts of industrial castors shall be free from abnormal damage and permanent deformation affecting the use, and the bearing (sleeve) shall rotate normally without looseness and jam Grid.
There are many advantages of industrial caster load-bearing walking test, which can detect the service life of this caster in long-time working condition. Under the same production process, through the comparison of industrial casters produced by different materials, the good and bad of castor materials can be identified. In the current profit driven environment, in order to reduce their own costs, some industrial caster manufacturers use recycled materials (some of the recycled materials have been recycled many times, with poor toughness and easy to break). Not only are there many burrs, but also the differences are poor transparency, dim color, poor elasticity, poor high temperature resistance and easy fracture. Therefore, these factors can lead to poor overall performance of industrial casters. As buyers and consumers, we should strengthen the awareness of this aspect in order to better protect their own rights and interests.
