How to change the caster of suitcase?

When we choose enough luggage, we should not only pay attention to the material of the case, but also pay attention to the purchase of casters is also a crucial issue. The key to the quality of caster is whether solid, smooth, noiseless, shiny, etc., these are the problems that we need to pay special attention to when we buy the pull box. In addition to the quality of caster, we also need to pay attention to the type of caster. Wanda caster below to introduce the choice of what kind of caster bar box.

The caster of the pull rod box on market now is divided into two kinds generally: one kind is universal wheel: universal wheel is very save effort when pushing horizontally, more suitable for those flatter road surface; The other is the one way wheel: the caster's pull box can be pulled easily and is also suitable for some uneven gravel roads, so the pull can be applied to many different roads. Let's take a look at the user's experience with these two casters.

1. The stability of one-way wheel is better; Universal wheel of effort, but the road requirements are higher.

2, suitcase or one-way wheel is good, in the case of heavy objects easy to grasp the direction, but the quality of the wheel is not good to say, when the general choice is mainly to see the appearance, with the thickness of the material, the general good rubber looking not dirty.

3, in fact, or to see their own journey use, I generally use universal wheel, because of the comparative effort saving, one-way I also used before, feel sometimes no universal convenience, as for the wheel? Can say oneself look carefully point, choose those who are more reliable manufacturer to make.

The key to the quality of caster is whether solid, smooth, noiseless, shiny, etc., these are the problems that we need to pay special attention to when we buy the pull box. In addition to the quality of caster, we also need to pay attention to the type of caster, now on the market of the caster box generally divided into two kinds, one is the universal wheel, one is a one-way wheel, universal wheel is very easy to push, more suitable for those more flat road surface.

One-way wheel the caster of the pull box can be very easy to pull, and for some uneven gravel road walking is also very suitable, so that the cable pull can be suitable for a lot of different road surface, and one-way wheel stability is better; Universal wheel of effort, but the road requirements are higher, one-way wheel in the case of heavy weight easy to grasp the direction, so let's say the selection of wheels.

We usually use ordinary TPE castor material, because the TPE castor material itself has stop slippery, so relatively TPU material wear-resisting performance will be better, but the TPE castor castor with material, the increase of load bearing requirements in TPE castor material to join the appropriate slip agent to improve its surface smooth, reduce the TPE castor material's surface friction coefficient, thus reducing friction heat production increase friction loss. So what advantage does wear-resisting TPE caster material have specifically? Then li en will introduce to you:

Bearing capacity of TPE materials is generally not very high. At present, the maximum bearing capacity of TPE as outsourcing adhesive in the domestic market is 300kg. Because the TPE material itself is relatively soft and rigid, and it is formed by bonding with the skeleton, a lot of heat will be generated during the load movement, which will accelerate the deformation of the material, thus causing the skeleton and rubber of the caster to fall off or break. The bearing capacity of the caster material can reach up to 300kg.

Common TPE material wear-resisting performance, because itself has slide relative to other material wear-resisting performance better, but the castor with TPE material along with the improvement of bearing, TPE castor material will join the appropriate slip agent to improve the surface smooth, reduce the material surface to reduce friction coefficient of friction heat production increase friction loss.

Different skeleton material selection method is not the same as castor skeleton for PP, PP, nylon, etc., commonly carry lower casters are commonly use PP skeleton, do some low-end material selection and even back to the material PP do skeleton, this kind of frame is more brittle, part at the same time there is mixed with other materials or degradation, so it is more to the bonding performance requirement of the TPE. If the PP is strengthened, it is generally strengthened by adding glass fiber, so it has higher requirements on the bonding performance of the material. The ordinary original package PP generally chooses homopolymer TPE caster material.
