"Shuisha..."
"Buy a 61128, otherwise the length is not enough, and you will need three tool holders! I told Da Qizi that the ingredients are 38CrmOAl, which does not require very good materials. They do not understand the mechanical properties when using this processing. Our current domestic materials can already Reached!"
"Pour one, and then roll it three times with our press. You need to order three knives! We can't do surface spraying. I'll give you the contact information later. You can contact them. They are right in front of us. It's not difficult! We polish it It can be done in the mold shop, and heat treatment is not difficult!”
"As for the price, how many pieces? By the way, show me the cannon barrel! This best cannon barrel is also made at my place to prevent the tolerances from not being done properly!"
Master He divided the screw into four sections and finally wrote the craftsmanship on it. The people in the inspection group opposite were dumbfounded. This is too damn fast.
According to the progress in the south, it would take at least three days to get a quote for the screw. There were various phone calls, and the other party even asked three or four times about the key tolerances in some places.
As for the screw barrel? Few people call this thing a cannon barrel. Only people in the industry know about it. The leader of the team quickly took out another drawing and enlarged it again to make a copy. Master He looked at it and nodded.
"This is not easy to process. It requires a long-arm knife, a honing machine, and a boring machine! We also have to customize the tool, which is a bit troublesome! This is the price!"
After reading all the drawings of the gun barrel, Master He wrote a small quotation to Ji Donglai. Ji Dong took a look at it and couldn't help but clicked his tongue in his heart, but after looking at the complicated craftsmanship on the drawings, he finally nodded.
"One hundred thousand barrels and one hundred thousand screws each? Why don't you go and grab it? We definitely don't have that much money to make one, huh!"
Ji Donglai wrote a quotation on the other party's drawings. The old man leading the team remained silent, but Mr. Cai was the first to jump up.
In the other party's impression, this thing definitely doesn't have this price, at least it won't cost so much to process it in China. The price surprised the other party. The price of this thing seemed to be very cheap last time abroad.
Ji Donglai didn't say anything here, because Ji Donglai absolutely believed in Master He's quotation. A set of 200,000 yuan was definitely not a bargain.
Mr. Cai wanted to say something else, but the old man waved his hand.
"Mr. Ji, please provide me with the performance of the alternative material you mentioned. I don't understand 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 men hurriedly moved the "Mechanical Design Manual" from the technology department.
From the performance of the materials to the comparison of domestic and foreign materials, the old man carefully checked, including the carbon content and various performance parameters.
"Well, Mr. Ji, have you successfully used screws processed with this material? Can you show us the quality of your processing? The screw and barrel are the core components of our equipment. You know that, what do you think? ?”
Taking off his glasses, the old man rubbed his eyes to hide his inner excitement.
The price of this screw in Mr. Cai's memory was actually US dollars, 30,000 US dollars a piece. Ji Donglai quoted 100,000 yuan. The other party thought it was high, but in fact he had never seen it on the market.
"This is simple, please follow me! Ai Xing, do we still have screws on site that have not been installed on the machine? If not, the maintenance equipment will pull out a screw!"
"To tell you the truth, all the screws for the extruders in our factory are manufactured by our own factory. From the establishment of the factory to the present, we have processed and manufactured corresponding screws for more than one factory, but it is difficult to process and manufacture such a complex screw as yours. It’s the first time.”
"And most of our screws are carburized or surface nitrided. What you require is hard chromium plating. The application situations of the two are different. We don't know what products you produce. The friction may be greater!"
Ji Donglai is no stranger to manufacturing screws. When production first started, Ji Donglai was also worried that the design in the factory did not meet the requirements. Later, after using it, he found that it was better than the original configuration, and he was completely relieved.
After using it for such a long time, the factory’s extruder has almost never had a problem.
"This screw is made well. Was it processed by a CNC lathe?"
Looking at the dismantled screw, the old man looked around with his glasses on. Whether it was the rounded corners at the root or the sharp corners at the top of the thread, the entire screw was well made.
Although it is only a three-stage model, the workmanship is not rough at all, and it can be seen that the craftsman is very careful.
"They are all processed by ordinary lathes. We can carburize ourselves, but nitriding needs to be done outside. This screw has been on the machine for six months. It is made of neoprene and the wear is not very large. If If you work in vain, the wear and tear will be great, and your materials may be in vain!"
Ji Donglai took the screw and took a few glances at it. The screw on Master He's car was absolutely fine.
As for splines and other small mechanisms, factory equipment makes them very easy.
"Do you make the screws for these extruders yourself?"
Looking at the large row of extruders in the molding workshop, the old man had questions in his eyes.
"That's not accurate. We modified this row of extruders ourselves. We just kept the frame of the original equipment after we bought it. We simply made the next few machines ourselves, with larger tonnage and more practicality."
"These large vulcanizing machines here, each with a capacity of 500 tons, are all made by ourselves. We are currently producing the bumper material for the car plate of the dumper. We have sold this product to all over the world."
"If you need our help in designing and manufacturing the extruder, we can do it!"
Ji Donglai pointed to his equipment and explained with a smile. The old man nodded and turned around to see the partition. The transparent window above was a little dark.
"Mr. Ji, what kind of equipment do you have here? We have visited this place, why don't you give us a look?"
These workshops were originally not within the scope of the inspection. Ji Donglai hesitated and asked Ding Aixing for dust caps. In addition, only five people from the other party were allowed to visit the site, including the old man, Lu Lu, and three technicians.
"The tipping bucket internal mixer seems to be a product of Big Rubber and Plastic, but it doesn't look like it. Some of the structures have changed!"
The old man was almost lying on top of the internal mixer to look at it. The other party also looked at the open mixer over there carefully. The 55-inch open mixer is not that big now. It does not refine rubber materials during the day. The plan is all Concentrated at night, when electricity prices trough.
"This set of equipment is also processed and manufactured by ourselves. Our factory's equipment manufacturing capabilities have always been strong, so foreigners choose to cooperate with us. The equipment is manufactured here, and you can even test the machine directly. We process everything from raw materials to post-processing The finished product, the whole set can be made.”
Pointing to the various equipment on site, Ji Donglai was filled with pride.
