"Brush ......"

"Buy a 61128, otherwise the length is not enough, and you have to match three with the knife holder! Tell Daqizi that the ingredient 38CrmOAl does not need too good materials, they do not know the mechanical properties with this processing, and we are now able to achieve the domestic materials! ”

"Pour one, then roll it three times with our press, and you have to set three knives! We can't do surface spraying, wait for me to give you a contact information, you contact them, right in front of us, it's not difficult! Polishing can be done in our mold workshop, and heat treatment is not difficult! ”

"As for the price, how many? By the way, show me the barrel! This best barrel is also working with me, so as to prevent the tolerance from not doing well! ”

Master He divided the screw into four sections, and finally wrote the process on it, and the group of people on the opposite side were stupid. It's also too fast for Nima.

According to the progress of the southern side, it will take at least three days to quote the screw, and all kinds of phone calls will be asked, as well as the key tolerances in some places inside, and the other party will even ask three or four times.

As for the screw? Few people call this thing cannon barrel, only people in the industry know, the leader of the team hurriedly took out another drawing, enlarged and copied it again, Master He saw it in his eyes and nodded.

"This is not easy to process, long arm knife, honing machine, boring machine! We also had to customize the knives, which was a bit of a hassle anyway! This quote! ”

After reading all the drawings of the cannon barrel, Master He wrote a small quotation to Ji Donglai, Ji Dong took a look, and couldn't help smacking his tongue in his heart, but looking at the complicated process on the drawings, he finally nodded.

"One hundred thousand barrels and one screw each? Why don't you grab it? We definitely don't have that much money to make one, huh! ”

Ji Donglai wrote a quote on the other party's drawings, and the old man who led the team over there didn't squeak, and Mr. Cai was the first to jump up.

In the impression of the other party, this thing definitely does not have this price, at least there will not be so much money for processing in China. The price surprised the other party, and the price of this thing seemed to be very cheap last time abroad.

Ji Donglai didn't speak, because Ji Donglai absolutely believed in Master He's offer, and he would definitely not bargain for a set.

Mr. Cai wanted to say something, but the old man waved his hand.

"Mr. Ji, the performance of this alternative material you said can help me provide it, I don't know it!"

Looking at the alternative materials written by Master He on the drawings, the other party frowned and asked, Ji Donglai waved his hand, and his subordinates hurriedly moved the "Mechanical Design Manual" from the technical department.

From the performance of the material to the comparison of domestic and foreign materials, the old man carefully checked, including the carbon content and various performance parameters.

"Well, Mr. Ji, do you have a screw that has successfully applied this material processing? Can you show us the quality of your machining, the screw and barrel are the core components of our equipment, you know, what do you say? ”

Taking off his glasses, the old man rubbed his eyes to hide the excitement in his heart.

In Mr. Cai's memory, the price of this screw is actually denominated in US dollars, 30,000 US dollars a piece, Ji Donglai quoted 100,000 yuan, and the other party felt that it was high, but in fact, he had never seen the market.

"It's easy, please follow me! Ai Xing, do we still have screws on site that have not been put on the machine? If not, the overhauled equipment draws a screw down! ”

"To tell you the truth, all the screws of the extruder in our factory are processed and manufactured by our own factory, from the establishment of the factory to the present, we have processed and manufactured the corresponding screw for more than one factory, but it is the first time to process and manufacture such a complex screw of yours."

"And the vast majority of our screws are carburized or surface nitriding, what you require is hard chrome plating, the application of the two is not the same, we don't know what products you produce, maybe the friction is greater!"

When Ji Donglai first started production, he was also worried that the design of the factory did not meet the requirements, and later found that it was better than the original machine configuration, which was completely relieved.

After being in operation for so long, the extruder in the factory has hardly had a problem.

"This screw is doing well, is it processed by CNC lathes?"

Looking at the dismantled screw, the old man looked around with his glasses, whether it was the rounded corners of the root or the sharp corners at the top of the thread, the whole screw was done well.

Although it is only a three-stage type, the craftsmanship is not rough at all, and you can see that the craftsman is very careful.

"It's all processed by ordinary lathes, we can carburize ourselves, nitriding needs to be done outside, this screw has been on the machine for six months, it eats neoprene, and the amount of wear is not very large. If you eat white work, the amount of wear and tear will be large, and your food may be eaten for nothing! ”

Ji Donglai also took a few glances at the screw, and the screw of Master He's car was absolutely fine.

As for splines and other small mechanisms, the equipment of the factory is very easy to do.

"These extruders are all screws that you make yourself?"

Looking at a large row of extruders in the molding workshop, the old man's eyes were full of questions.

"Not accurately, this extruder is all modified by ourselves, and we only keep the frame after we bought the original equipment. The latter ones are simply made by ourselves, with a larger tonnage and more practical. ”

"These large vulcanizers here, 500 tons, are all made by ourselves, and now we are producing the cushioning material for the dumper against the car plate, which we have exported to all over the world."

"If you need us to help design the extruder, produce it, you can do it!"

Ji Donglai pointed to his equipment and explained with a smile, the old man nodded, and when he turned around, he happened to see the partition, and the transparent window above was a little black.

"Mr. Ji, what kind of equipment do you have here? We've all visited this area, and we've seen it too? ”

These workshops were not within the scope of the inspection, Ji Donglai hesitated, and asked Ding Aixing to come to the dust hat. In addition, only five people from the other side are allowed to visit the site, including the old man, the land route, and three technicians.

"Tipping mixer, this seems to be a big rubber and plastic product, but it doesn't look like it, some structures have changed!"

The old man almost lay on the top of the mixer and looked at it, and the other party also carefully checked the refining machine over there, the fifty-five-inch refining machine is not big now, and it does not refine rubber during the day, and the plan is all concentrated at night, when the electricity price is at the trough.

"This set of equipment is also processed and manufactured by ourselves, and the equipment manufacturing capacity of our factory has always been very strong, so foreigners will choose to cooperate with us, the equipment is manufactured in our place, and you can even test the machine directly, and we can do a full set from raw material processing to later finished products."

Pointing to the various equipment on the scene, Ji Donglai's heart was full of pride.
