I believe that many machine repair workers have had this idea when they opened their own knitting factory, the machine can be repaired, what’s so hard about buying a bunch of accessories and putting them together? Of course not.

Why do most people buy new phones?

We discuss this matter from two aspects: whether it is good or not to assemble it ourselves, and whether it is worth it.

Let’s start with assembling it ourselves.

First: from the foot of the machine, cambox, plate, gear, top plate and other components need natural aging to eliminate stress to ensure the stability and accuracy of the components. Strong quality machinery factories will be at least half a year in advance, purchase enough inventory through wind, sun, rain, four seasons temperature changes to eliminate stress on the components, assembly of their own waiting time can be available?

Second: There are three kinds of cams, knit cam (into a circle /knit), tuck cam (set circle /tuck),miss cam(floating line /miss), very simple right. But do you know how many times the curve of the cam has been opened and tested repeatedly in the machinery factory? The pressure needle time is a little deeper or a little shallower, the pressure needle time is a little longer or a little shorter, the slope of the curve is a little slower or a little steeper, the needle is a little higher or a little lower, and so on, the difference is very small, the cloth effect is a thousand miles away. These are the best solutions to be found after repeated modification and debugging after feedback from market demand and test. Are the trial and error costs worth it?

Note: The difference between the two cam’s curves is only a little bit, but the effect is very different.

Third: the circular knitting machine only the cam box is important, the other does not matter! Is this really the case? The accuracy of the cam box (loop system) is important, but it does not mean that other systems are not important. Just as the car engine is important, the chassis and brake system are not important? Computer CPU is important, graphics card, memory is not important? No matter how good the cam box is, it does not have a stable and precise transmission mechanism, yarn feeding mechanism, pulling mechanism, and supporting members, can it come out with a good cloth? Of course, you can say that I buy the best yarn and other parts, but don’t forget that the original intention of their own assembly is to save costs, transmission mechanisms and support components need natural aging and finishing, and excellent machinery factories can choose the most appropriate combination according to their own brand price and market positioning, in their own pricing range balanced preparation of the best results.

Fourth: patchwork is the most deadly, each brand of machine systems have been adjusted for years, and some people assemble is here to choose a little bit over there. Parts manufacturers are based on the design of the circular machinery factory to produce parts, the specific collocation and scope of application is not clear, and the various brands of machinery are not necessarily suitable. Of course, some friends will say that I found a certain model of a certain brand, found his spare parts manufacturers one by one, and bought them back for assembly.

We assume you’re connected, remove all barriers. After some operation, let’s see if it is worth it: the average gross profit of machinery factories in the circular machine industry is less than 10%, which also includes natural aging, the cost of inventory, the cost of collection period, the cost of after-sales, and the risk of bad debts. The amount of spare parts you buy is not an order of magnitude with the machinery factory, and the price can be the same, in addition, you have to talk with each spare parts manufacturer about the delivery period and the account period. In this way, it costs a lot of time and energy, and it may not save the cost, but also at great risk, in case the assembly of the cloth effect is not good, can not find the reason, even the basic after-sales is not available, you can not dismantle the accessories to return it.

So professional things should be left to professional people to do!
