Trunk truckle to how to choose?

When we choose enough luggage not only pay attention to the body material problem, also note the choose and buy of castor is also crucial problem. Caster and whether the key to the quality of the firm, whether smooth, there is no noise, whether luster, etc. , these are all we buy pull rod box need special attention. In addition to the quality problem of the caster, we also note is the problem the kinds of castor. Wanda castor is to introduce for everybody below pull rod box to choose what kind of castor. Now on the market of the pull rod box of castor generally fall into two kinds: one kind is universal wheel, universal wheel flat when pushed very effort, suit to the road that are flat; There is a round is one-way: this castor of pull rod box can be easily sew, and for some rough gravel road is also good for walking, so suspension can be suitable for many different roads. Take a look at below the user experience of the two kinds of casters. 1, the stability of the one-way wheel is better; Universal wheel and effort, requiring only on the road. 2, luggage or one-way wheel is good, in the case of a heavy easy to grasp the direction, but the wheel quality is bad to say, generally choose the basically is to see the appearance, the thickness of the material, generally good rubber is not corrupt. 3, actually still depends on his own journey purposes, usually I use universal wheel, because it's effort, one-way I used before, sometimes feel not universal convenience, as for the wheels? Can only say that they see careful, choose those made in reliable manufacturers. Caster and whether the key to the quality of the firm, whether smooth, there is no noise, whether luster, etc. , these are all we buy pull rod box need special attention. In addition to the quality problem of the caster, we also note that is the problem of castor varieties, now on the market of the pull rod box of castor generally fall into two kinds, one kind is universal wheel. It is a one-way wheel, universal wheel flat push very effort, when is suitable for surfaces that are flat. One-way round this castor of pull rod box can be easily sew, and for some rough gravel road is also good for walking, so suspension can be suitable for many different pavement, and the stability of the one-way wheel is better; Universal wheel and effort, but on the road is higher, one-way wheel in the case of a heavy easy to grasp the direction, then we talk about the wheels for selection. 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 wear-resisting TPE castor material specific what are the advantages? So well to introduce for you: bearing capacity TPE material bearing capacity does not generally high, the current domestic market with TPE do outsourcing rubber bearing up to 300 kg. Because the TPE material itself is soft and rigid is not high, and the skeleton is made of bonding way of forming, so the load movement will produce a great quantity of heat, accelerate the deformation of the material, resulting in castor frame and the rubber appear fall off or broken, caster wheel bearing up to 300 kg of material. 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 it is reinforced PP inside generally adopt the way of joining fiberglass enhanced, so the bonding properties of the materials also have higher requirements. The original ordinary PP type generally choose homopolymerization of TPE castor material. / news_184。
