Return to the exciting era of 1999

Chapter 340 You really have never seen the world
"Swipe..."

"Buy one 61128, otherwise the length is not enough, and you need to match three tool holders! I told Da Qizi that the ingredient 38CrmOAl does not need too good materials. They don't understand the mechanical properties of this processing. Our domestic materials can already Reached!"

"Pour one piece, and then roll it three times with our press, and you have to order three knives! We can't do surface spraying, I will give you a contact information later, you can contact them, right in front of us, it's not difficult! Polishing us It can be done in the mold shop, and the heat treatment is not difficult!"

"As for the price, how many pieces? By the way, show me the gun barrel! The best gun barrel is also made here, in case the tolerance is not done properly!"

Master He divided the screw into four sections, and finally wrote the craftsmanship on it. The people from the inspection team on the opposite side were all stupid.This is too damn fast.

According to the progress in the south, it will take at least three days for the quotation of the screw, various phone calls, and key tolerances in some places, and the other party even asks three or four times.

As for the screw barrel?Few people call this thing a cannon barrel. Only those in the industry know it. The leader of the team hurriedly took out another blueprint, enlarged and copied it again, and Master He nodded when he saw it.

"This is not easy to process, long arm knife, honing machine, boring machine! We have to customize the tool, anyway, it's a bit troublesome! This is a quotation!"

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 click his tongue, but he looked at the complicated craftsmanship on the drawings, and 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 quotation on the opponent's drawing, the old man who led the team over there said nothing, and Mr. Cai was the first to jump up.

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

Ji Donglai didn't say a word here, because Ji Donglai absolutely believed in Master He's quotation, which was [-] sets, absolutely not worth the price.

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

"Mr. Ji, please provide me with the performance of the alternative material you mentioned, I don't know much about it!"

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

From the performance of materials to the comparison of materials at home and abroad, the old man carefully checked, including carbon content and various performance parameters.

"Well, Mr. Ji, have you successfully applied this material to process the screw? Can you show us your processing quality? The screw and barrel are the core components of our equipment. You know it. What do you say? ?”

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

The price of the screw in Mr. Cai's memory is actually denominated in US dollars, 10 US dollars a piece, and Ji Donglai quoted [-] yuan. The other party thought it was high, but he had never seen it on the market.

"It's simple, please come with me! Ai Xing, do we still have any screws on site? If not, take a screw out of the equipment for maintenance!"

"To tell you the truth, all the screws of our factory's extruders are processed and 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 complicated screws as yours. It's the first time."

"Moreover, most of our screws are carburized or surface nitrided. What you require is hard chrome plating. The application occasions of the two are different. We don't know what products you produce, and the friction may be greater!"

Ji Donglai is no stranger to manufacturing screws. When the 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 machine configuration, so he was completely relieved.

It has been used for such a long time, and the factory's extruder has almost never had a problem.

"This screw is well made, is it processed by a CNC lathe?"

Looking at the disassembled screw, the old man looked around with glasses on. Whether it was the rounded corner at the root or the sharp corner at the top of the thread, the whole screw was well made.

Although it is only a three-stage style, the craftsmanship is not rough at all, and it can be seen 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 used on the machine for six months. It eats neoprene, and the wear is not very large. If If you eat for nothing, the amount of wear and tear will be large, and your material may be eaten for nothing!"

Holding the screw, Ji Donglai also took a few glances. The screw of Master He's car is absolutely fine.

As for splines and other small mechanisms, it's pretty easy to do with factory equipment.

"These extruders are all screws made by yourself?"

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

"That's not accurate. This row of extruders was rebuilt by ourselves. We only kept the frame after we bought the original equipment. The latter ones are simply made by ourselves. They have a larger tonnage and are more practical."

"The [-]-ton large vulcanizing machines here are all made by ourselves. Now we are producing the cushioning material for the car dumper. We have exported this product to all over the world."

"If you need us to help design the extruder and manufacture it, we can do it!"

Ji Donglai pointed to his equipment and explained with a smile. The old man nodded and turned his head to see the partition. The transparent window on it was a little black.

"Mr. Ji, what kind of equipment do you have here? We have all visited this place, so let us see it?"

These workshops were originally not within the scope of inspection, so Ji Donglai hesitated and asked Ding Aixing for dust caps.In addition, only five people from the other party are allowed to visit the site, including the old man, Lulu, and three technicians.

"Tipping bucket internal 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 was almost lying on top of the mixer, and the other side of the mixer over there also checked carefully. The 55-inch mixer is not too big now, and it does not refine rubber during the day. The plan is all concentrated in At night, when the price of electricity fluctuates.

"This set of equipment is also processed and manufactured by ourselves. Our factory's equipment manufacturing capacity has always been very strong, so foreigners choose to cooperate with us. The equipment is manufactured here. You can even test the machine directly. We process everything from raw material processing to post-production. The finished product, the whole set can be made.”

Pointing to the various equipment on site, Ji Donglai was full of pride.
