Chapter 233 I Am The Strongest Among People You Know

"Donglai, should we make a larger screw and use a vertical injection machine? There are too many problems with this kind of injection machine in China, and it is difficult to meet the requirements at one time."

"Let Master Ji do the electronic control system. If possible, I will ask the technical department to make the drawings!"

This rubber spring Ji Donglai opened a mold with four cavities, each rubber spring needs six kilograms of rubber, four is 24 kilograms!
Ji Donglai obtained the maximum injection volume of the injection machine from the switch accessory factory, which is only a little over eight kilograms, and the screw rod is not worn.

The machines are basically bedroom injection machines, which occupy a larger space and consume more energy. Liu Jiahui, the old man of the equipment team, has been looking at them for a long time, and this time he just took advantage of the opportunity of new product development to suggest to Ji Donglai.

"Do it, do it at the fastest speed! Our product is for export. If the first sample is successful, we will make the second one! In addition, Master Liu, look at the mold opening of this product will be very difficult, with such a large contact surface, The rubber bonded to the metal will be very firm! Directly let the master who is doing the electric control make the mold opening into an automatic mold splitting, saving the labor of the workers!"

"In the future, if there is such a thing, make the design drawings first, and then ask me to sign it directly. If you block your ass, you will be too panicked. Let's do it!"

Faced with various suggestions from his technical department, Ji Donglai was very supportive.

Liu Jiahui laughed silly for a while, in fact, it was because he had nothing to do these few days, otherwise the other party would be lazy.

The entire enterprise is not very slow now, and the group of people who came later were worried that Ji Donglai would forget his group of people, so they just showed it, otherwise the other party would not bother to get such a small device.

Because this kind of screw is not difficult, the other party immediately calculated the amount of rubber injection, then directly found an idle horizontal injection machine, and changed it on it!
The rubber injection machine is actually not difficult to make. The longest screw is no more than two meters, and it only serves to swallow material and maintain pressure.

After measuring various parameters, Liu Jiahui immediately installed a screw on the equipment group, the length-to-diameter ratio reached [-], and then went to Ji Ping to start changing the electric control.

In fact, it is PLC programming. In terms of software, Ji Ping has two knives. The ideas are ready-made in the other party's mind, and the other party dictates. Ding Aixing and his group directly input the drawings into the computer, and then convert them to the machine.

The people who modified the machine were busy, and Ji Donglai and his group were not idle. As the mold was automatically pushed out by the equipment, He Xiaolong took a copper screwdriver to pry the mold open, and nearly ten kilograms of rubber springs fell directly on the mold. on the base.

Abbas immediately went to check. To the surprise of the other party, there was no crack at the joint between rubber and metal, and the rubber surface was very smooth.

"Ji, how did you do it?"

Another rubber spring out of the mold with this rubber spring has almost the same effect, and there is no slight flaw on the surface, just wait for the product to cool down and paint the surface.

"This is a real technique. There is a saying in China that eight chefs can make eight dishes for one dish, that is, eight flavors and degrees of heat! If you don't believe me, you can go to a Chinese restaurant to order and try it!"

"The supplier you are looking for not only doesn't understand the rubber material, but also the molding process, and the adhesive they use is not good. The most important molds are all opened by outsourced units. I have my own independent mold factory. understand?"

"Just now you also saw that my equipment group is now able to make and modify equipment independently. If you go to any factory, can they do it? I dare not say that I am the strongest in China, but I am definitely the best Chinese manufacturer you know. Alright! I bet, if you take pictures of all the crafts I use to the supplier, he still can’t make the same product as mine, let’s try it if you don’t believe me!”

When Ji Donglai faced Abbas's novice behavior, he kept talking in vernacular, and Abbas kept laughing stupidly, not daring to take any pictures.

In fact, Ji Donglai is really not afraid at all, the three elements of polymer raw material molding, formula, time, and pressure!Give you any one factor, let you match the other two factors, you can try to crash.

Even if you are given two factors, and the most important formula is given to you, it will still break you down without giving you the mold design structure.

Polymer is not the most mysterious thing in material molding, but it is definitely the most troublesome thing in it.It is not important that the products produced are perfect in the initial stage, but the most important thing is that the performance of the products is stable and durable during mass production.

Ji Donglai chatted with Abbas for more than an hour. The rubber springs were basically cold. Ji Donglai took Abbas to stare at the workers for experiments.

The hardness, rubber hardness, pressure value, and shear force were all qualified, and Ji Donglai asked the workers to pack Abbas.

"Boss, the funds from Europe have arrived, and we can proceed to the next step."

Zhao Shuying walked up to Ji Donglai and whispered, Ji Donglai nodded, and directly waved his hand to let the sales department place an order, and then the compensation chain began to cut marks.

As for the lock buckle in the stamping workshop, stamping and bending have already started. With the action of the stamping machine, the round steel is squeezed into a U shape in the mold in minutes.

In the next step, the workers directly take another press to flatten and shape the ears of the buckle, and then punch holes in the middle.

The next step is to wait for the parts to cool naturally and then tap, and the last part is hot-dip galvanized.

"Ji, you are so fast! We will have other orders for you, can you give me an electronic sample booklet of the products you can make? I think we can have a lot of cooperation, you are amazing! "

Ji Donglai's workers drew a line on the field, and then began to drag the compensation chain, and then the hydraulic pliers stopped directly, and the next step was to peel off the skin, and every step was orderly.

As for the cut chain links, someone collects them and puts them in a special container for recycling. As for the skin left by the compensation chain, the workers also collect them for reuse.

The labels were printed upstairs and fixed on each compensation chain with cable ties, and someone specially took pictures of the status of the compensation chain.

As an international student from a non-industrialized country, Abbas had to admire the efficiency of Ji Donglai's group of people. Although they joked sometimes, they were absolutely quick at work.

"There will definitely be more cooperation. To tell you the truth, I am now making elevator accessories. In the future, I will take elevators. If your relatives can sell elevators or even sell elevators there in the future, we can do the same. It’s not enough now, I don’t have enough people!”

"The compensation chain will finish working overtime tonight, just come and arrange delivery tomorrow!"

After signing the sales form, Ji Donglai waved his hand and the engineering department pulled a small reducer out of Gao Gaohe's warehouse.
