"Donglai, do you want to 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 I can, I'll let the technical department make the drawings!"

This rubber spring Ji Donglai is a mold of four cavities, and the amount of rubber required for each rubber spring is six kilograms, and four is twenty-four kilograms!

Ji Donglai got the maximum injection volume of the injection machine from the switch accessories factory was only a little more than eight kilograms, and the screw was 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 group, has been watching it for a long time, and this time he just took the opportunity of new product development to suggest to Ji Donglai.

"Do it, do it as fast as you can! Our product is exported, and the second one will be made if the first sample is successful! In addition, Master Liu, it will be very difficult for you to open the mold of this product, such a large contact surface, the rubber bonding metal will be very strong! Directly let the master who does the electronic control make the mold opening into an automatic parting mold, saving the labor of the workers!"

"In the future, if there is such a thing, make design drawings first, and then ask me directly to sign, and then pull more panic to block the ass door, let's get it!"

In the face of various suggestions from his technical department, Ji Donglai was very supportive.

Liu Jiahui laughed for a while, in fact, because he had been fine for the past few days, otherwise the other party would have been lazy.

The whole enterprise is not very slow now, and the later people are worried that Ji Donglai will forget about his group, so this is how to show it, otherwise the other party will not be bothered to get this kind of small equipment.

Because this kind of screw is not difficult, the other party immediately calculated the amount of rubber injection, and then directly found an idle horizontal injection machine, and changed it on it!

The rubber injection machine is actually not difficult to do, the longest screw is not more than two meters, but it only plays a role in swallowing and holding pressure.

After the measurement of various parameters, Liu Jiahui immediately gave a screw to the equipment group, with a length-diameter ratio of 20, and then found Ji Ping to come over and change the electronic control.

In fact, it is PLC programming, and Ji Ping is a second knife in terms of software, and the ideas are ready-made in the other party's mind, and the other party dictates, Ding Aixing's gang 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 gang were not idle, with the mold being 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 base. qδ

Abbas immediately stepped forward to check, and to the surprise of the other party, the rubber and metal joints were not cracked at all, and the rubber surface was very smooth.

"Ji, how did you do that?"

The effect of another rubber spring molded together with this rubber spring is almost the same, and there is no flaw on the surface, just waiting for the product to cool and paint the surface.

"This is the real technology, there is a saying in China, one dish is made by eight chefs, that is, eight flavors and heat! If you don't believe it, you can order food at a Chinese restaurant and try it!"

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

"Just now you saw that my equipment team is now able to make and modify equipment independently, you go to any factory, can they? I don't dare to say that I am the strongest in China, but definitely the best Chinese manufacturer you know! I bet if you take a picture of all the processes I use now and send them to that supplier, he still can't make the same product as me, so let's try it if you don't believe me!"

Ji Donglai faced Abbas's little white behavior in all kinds of vernacular, and Abbas kept laughing, 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, and you can try to crash.

Even if you are given two factors, the most important of which is the formula, will still make you collapse without giving you the mold design structure.

Polymers are not the most mysterious in material molding, but they are definitely the most headache in it. It is not important that the product is perfect in the early stage, the most important thing is that the performance of the product is stable and durable during mass production.

Ji Donglai chatted with Abbas for more than an hour, and the rubber spring was basically cold, and Ji Donglai took Abbas to stare at the workers for experiments.

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

"Boss, the money from Europe has arrived, and we can move on to the next step."

Zhao Shuying walked next 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 the mark.

As for the lock on the side of the stamping shop, stamping and bending have now begun, and with the action of the stamping machine, the round steel is extruded into a U-shape in the die in minutes.

In the next step, the worker directly took another press to flatten and shape the ears of the lock, and then punched the hole in the middle.

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

"Ji, you're moving so fast! We will also have other orders for you, can you give me a digital version of the products you can make? I think we can work together a lot, you're amazing!"

Ji Donglai's workers drew lines on the site, and then began to drag the compensation chain, and then the hydraulic pliers were directly interrupted, and the next step was to peel off the epidermis, and every step was orderly.

As for the sheared chains, they are collected and put into special containers for recycling, and the skins left over from the compensation chains are also collected by workers to be ready for reuse.

The label is printed upstairs, fixed on each compensation chain with a cable tie, and someone specially takes pictures of the status of the compensation chain.

As a student from a non-industrialized country, Abbas has to admire the efficiency of Ji Donglai's group, although there are jokes from time to time, but the work of this group is absolutely good.

"There will definitely be more cooperation, to tell you the truth, I am now making elevator accessories, I will take the elevator in the future, if your relatives can sell elevators in the future and even sell elevators over there, we can do the same, not yet, I don't have enough manpower!"

"The compensation chain will work overtime tonight, and you can come over tomorrow to arrange delivery!"

signed the list on the sales side, Ji Donglai waved his hand, and the engineering department pulled a small reducer out of Gao Gaohe's warehouse.
