Chapter 340 You really haven't seen each other

“Brush…”

"Buy a 61128, otherwise the length is not enough, and you have to match three with the knife holder! Tell Da Qizi that the ingredients are 38CrmOAl do not require too good materials. They do not understand the mechanical properties when using this processing. Our domestic materials are now able to

It's reached!"

"Pour one, then roll it with our press three times. The tool must be set three times! We can't do the surface spraying. I'll give you a contact information later. If you contact them, it's not difficult to polish us!

It can be done in the mold workshop, and heat treatment is not difficult!”

"As for the price, how many pieces? By the way, show me the cannon barrel! This is the best cannon barrel for me to prevent the tolerance from being done well!"

Master He divided the screw into four sections and finally wrote the craftsmanship on it. The group of people from the inspection team opposite were stunned. This was so damn fast.

According to the progress of the south, it will take at least three days to talk about the screw quotation. It will be asked by various phone calls, and there are key tolerances in some places inside. The other party even asked three or four times.

As for the screw cylinder? Few people call this kind of gun cylinder. Only the people in the industry know that the leader of the team hurriedly took out another drawing and enlarged it to copy it again. Master He nodded in his eyes.

"This is not easy to process, long-arm knife, honing machine, boring machine! We also have to customize the tools, it's a bit troublesome! This quote!"

After reading all the drawings of the cannon barrel, Master He wrote a small offer to Ji Donglai. Ji Dong took a look and couldn't help but be amazed, but looked at the complex craftsmanship on the drawings and finally nodded.

"One hundred thousand gun barrel and screw are each? Why don't you grab it? We definitely don't have that much money to make one, hum!"

Ji Donglai wrote a quote on the other party's drawings. The old man who led the team there did not say anything, and Mr. Cai was the first to jump up.

In the other party's impression, this thing definitely does not have this price. At least it won't cost so much to process it in China. The price surprised the other party. The price last time this thing seemed to be very cheap.

Ji Donglai didn't say anything because Ji Donglai definitely believed in Master He's offer. If he had a set of things, he would never give a price.

What else did Mr. Cai want to say, and the old man waved his hand.

"Mr. Ji, I don't know about the performance of the alternative material mentioned by Ji!"

Looking at the replacement materials written by Master He on the drawings, 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 the material to the comparison between domestic and foreign materials, the old man carefully checked it, including carbon content and various performance parameters.

"Well, Mr. Ji, have you successfully processed screws with this material? Can you show us your processing quality? The screws and gun barrels are the core components of our equipment? You know, what do you think?

?”

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

In Mr. Cai’s memory, the price of this screw is actually denominated in US dollars, 30,000 US dollars per piece, and 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 come with me! Aixing, are there any screws on the machine on site? If not, draw a screw for the maintenance equipment down!"

"To be honest, all the screws in our factory's extruder are processed and manufactured by our factory. From the construction of the factory to now, we have processed and manufactured corresponding screws for more than one factory, but the screws that are so complicated to process and manufacture.

It's the first time."

"And most of our screws are carburized or surface nitriding. What you require is hard chromium plating. The two are not the same. We don't know what products you produce, and the friction may be greater!"

Ji Donglai is not unfamiliar with the manufacturing of screws. When he first started production, Ji Donglai was worried that the design in the factory would not meet the requirements. Later, after using it, he found that it was better than the original machine, so he was completely relieved.

After using it for so long, the factory's extruder has almost never had any problems.

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

Looking at the disassembled screw, the old man wore glasses to look around. Whether it was the rounded corners at the root or the sharp corners 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 craftsmen are very attentive.

"It's all processed by ordinary lathes. We can carburize ourselves, so we need to go outside to make nitriding. This screw has been used for six months and is consuming neoprene, so the wear amount is not very large.

The amount of wear and tear will be high when you eat it, and your ingredients may be simplified when you eat it!"

Ji Donglai also took a few glances with the screw. Master He had absolutely no problem with the screws on his car.

As for splines and other small institutions, the factory equipment is very easy to make.

"Are these extruders made by you yourself?"

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

"Inaccurate, we transformed this row of extruders ourselves. We bought the original equipment and only retained the frame. The latter ones were simply made by us, with a larger tonnage and more practical."

"We are all made by ourselves, including 500 tons of large vulcanizers. We are now producing rollover machines with vehicle plate buffer materials. This product has been sold all over the world."

"If you need our help designing the extruder and manufacturing, you can do it!"

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

"Mr. Ji, what equipment is there on your side? We have visited here and give us some insights?"

These workshops were not within the scope of the investigation, so Ji Donglai hesitated for a while and asked Ding Aixing to come to the dustproof hat. In addition, only five people from the other party were allowed to visit the site, including the old man, land, and three technical personnel.

"The dump mixer seems to be a product of large rubber and plastic, but it doesn't look like it, some of the structure has changed!"

The old man was almost lying on the dense mixer to look at it. The other party on the diving machine there also looked carefully. The fifty-five-inch diving machine is not big now, and he does not refine rubber during the day. All plans are

Concentrate at night, when electricity prices are trough.

"This set of equipment is also processed and manufactured by ourselves. Our factory's equipment manufacturing capabilities have always been very strong, so foreigners choose to cooperate with us. The equipment is manufactured here, and you can even directly test the machine. We go from raw material processing to later stage

The finished product can be made in full set.”

Pointing at the various equipment on the scene, Ji Donglai felt proud.
