"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 make the electronic control system. If possible, I will ask the technical department to draw the drawings!"
This rubber spring Ji Donglai opened is a mold with four cavities. The amount of rubber required for each rubber spring is six kilograms, four is twenty-four kilograms!
Ji Donglai obtained from the switch accessory factory that the maximum injection volume of the injection machine was only a little more than 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 looking at 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, The rubber bonded to the metal will be very strong! Let the master who makes the electronic control directly make the mold opening automatic, saving workers' labor!"
"In the future, if something like this happens, first make the design drawings, and then come to me to sign directly. If you block the door, you will panic, so 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 made changes on 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 material and maintaining pressure.
After measuring various parameters, Liu Jiahui immediately put a screw into the equipment team with an aspect ratio of 20, and then asked Ji Ping to come over and modify the electronic control.
In fact, it is PLC programming. In terms of software, Ji Ping is second-hand. 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 gang were also busy. As the mold was automatically pushed out by the equipment, He Xiaolong took a copper screwdriver and pried the mold open laboriously. Nearly ten kilograms of rubber springs fell directly onto the mold. on the base. qδ
Abbas immediately stepped forward to check. To the other party's surprise, there was no crack at the joint between rubber and metal, 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 different 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. understand?"
"You just saw that my equipment team can now independently make and modify equipment. If you go to any factory, can they? 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 novice's behavior like Abbas, he said all kinds of nonsense. Abbas kept laughing and did not dare to take any photos.
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 I 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 in material molding, but they are definitely the most troublesome. It doesn’t matter if the product is perfect at the beginning. The most important thing is that the product’s performance is stable and durable during mass production.
Ji Donglai and Abbas chatted for more than an hour. The rubber spring was basically cold. Ji Donglai took Abbas and stared at the workers to do experiments.
The hardness, rubber hardness, pressure value, and shear force were all 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 squeezed into a U shape in the mold in minutes.
In the next step, the workers directly get another press to flatten and shape the ears of the lock, and then punch holes in the middle.
The next step is to wait for the part to cool naturally and then tap it, and 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 book 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. Someone also 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 there were jokes from time to time, these people 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. Not yet, I don’t have enough manpower!”
"The compensation chain will be completed after overtime work tonight. Just come over tomorrow to arrange delivery!"
After signing the order from the sales side, Ji Donglai waved his hand and the engineering department pulled a small reducer out of Gao Zhonghe's warehouse.
