Chapter 233 I am the strongest person you know

"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 possible, I will ask the technical department to draw the drawings!"

The rubber spring Ji Donglai opened is a mold with four cavities. The amount of rubber required for each rubber spring is six kilograms, four equals to twenty-four kilograms!

Ji Donglai obtained from the switch accessory factory that the maximum injection volume of the injection machine was only a little over eight kilograms, and this was when the screw was not worn.

The machines are basically bedroom injection machines, occupying a larger space and consuming more energy. Liu Jiahui, the old man of the equipment team, has been watching them for a long time, and this time he just took advantage of the opportunity of new product development to make suggestions to Ji Donglai.

"Do it, do it as quickly as possible! This product of ours 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. It will be very difficult. With such a large contact surface,

Rubber bonding to metal will be very strong! Directly ask the electronic control master to make the mold opening automatic, saving workers' labor!"

"In the future, if there is something like this, first make the design drawings, and then ask me to sign directly. If you block the butt door and make me panic, let's do it!"

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

Liu Jiahui laughed stupidly, but it was actually because he had nothing to do these days, otherwise the other party would also be lazy.

The entire enterprise is not very slow now. The next group of people are worried that Ji Donglai will forget about his group, so they show it off, otherwise they will not bother to get such small equipment.

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 modified it!

In fact, it is not difficult to make a rubber injection machine. The longest screw is no more than two meters, and it only serves the purpose of swallowing materials and maintaining pressure.

After measuring various parameters, Liu Jiahui immediately placed a screw for the equipment team, with the aspect ratio reaching 20, and then went to Ji Ping to start modifying the electronic control.

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

The people modifying the machine were busy working, and Ji Donglai and his team were also busy. As the mold was automatically pushed out by the equipment, He Xiaolong took a copper screwdriver and pried open the mold with great effort. Nearly ten kilograms of rubber springs fell directly onto the mold.

on the base.

Abbas immediately stepped forward to check. To his great surprise, the joint between rubber and metal did not crack at all, and the rubber surface was very smooth.

"Ji, how did you do it?"

The other rubber spring that was molded together with this rubber spring has almost the same effect. There is no flaw on the surface. I just wait for the product to cool down and paint the surface.

"This is real technology. There is a saying in China that eight chefs can make eight kinds of dishes, 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. Moreover, the adhesive they use is not good. The most important molds are made by outsourced units. I have my own independent mold factory.

Do you understand?"

"You just saw that my equipment team can now independently make and modify equipment. 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 strongest among the Chinese manufacturers you know.

Okay! I bet, if you take pictures of the process I am using now and show it to that supplier, he still can’t make the same product as me. If you don’t believe me, let’s give it a try!”

When Ji Donglai faced the behavior of a novice like Abbas, he said all kinds of nonsense. Abbas kept laughing and did not dare to take any pictures.

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

Even if we give you two factors, including the most important formula, without giving you the mold design structure, you will still collapse.

Polymers are not the most mysterious thing in material molding, but they are definitely the most troublesome. It is not important that the product is perfect at the beginning. The most important thing is that the product has stable performance and durability during mass production.

Ji Donglai and Abbas chatted for more than an hour. The rubber spring side was basically cold. Ji Donglai and Abbas stared at the workers to do experiments.

In terms of hardness, rubber hardness, pressure value, and shear force, all of them were qualified. Only then did Ji Donglai let the workers pack Abbas.

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

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

As for the locks in the stamping workshop, stamping and bending have now begun. With the action of the stamping machine, the round steel is extruded into a U shape in the mold in minutes.

In the next step, the worker directly takes another press to flatten and shape the ears of the lock, and then punches holes in the middle.

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

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

"

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

As for the cut chain links, a dedicated person collects them and places them in a special container for recycling. As for the skin left over from 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 photos 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. Although they joked sometimes, they were absolutely quick in their work.

"There will definitely be more cooperation. To tell you the truth, I am making elevator accessories now, and I will ride in the elevator in the future. If your relatives can sell elevators in the future, they can even sell elevators there. We can do the same.

It’s not possible now, I don’t have enough manpower!”

"The compensation chain will be finished working overtime tonight. Just come over and arrange the delivery tomorrow!"

After signing the order from the sales side, Ji Donglai waved his hand and the engineering department pulled a small reducer from Gao Zhonghe's warehouse.
Chapter completed!
