The rejuvenation of a great nation: from educated youth to national treasure scientist

Chapter 68 PPS Mass Production Issues
Wang Haoran said: "Let's see how the corn harvest is this year."

Li Gang said: "I have also seen that the corn is growing well this year and it looks like we can have a good harvest."

"That plant growth regulator of yours is really useful."

Wang Haoran smiled and said, "I estimated that the yield of corn per mu this year should be more than 7 kilograms."

Li Gang was very happy: "If it is true, it would be great."

“Also, it would be even better if wheat production could increase significantly.”

Wang Haoran said: "Yes, we can also research the growth hormone of wheat. When we plant wheat this year, we can use it to mix with seeds. Maybe it will be very useful."

As they were talking, they arrived at the brigade headquarters.

A green military jeep was parked in the compound of the brigade headquarters.

Two soldiers were standing there, talking to Li Jieshi.

The leading soldier was tall and had a majestic and domineering look.

Seeing Wang Haoran coming over, the soldier smiled and nodded, then came over to shake hands with Wang Haoran: "Comrade Haoran, hello!"

"I am the head of the Fifth Machinery Department. My name is Wang Cunxian."

Wang Haoran hurriedly greeted: "Hello, Comrade Cunxian!"

The Fifth Ministry of Machine Building is a department specifically responsible for conventional weapons.

Wang Haoran thought, the other party should be here for the Type 77 rifle?
Li Jieshi invited several people to sit down in the brigade headquarters.

Wang Cunxian said to Wang Haoran: "Comrade Haoran, the evaluation results of the Type 77 automatic rifle you designed are excellent."

"There are many eye-catching innovations in the gun you developed. After evaluation by our experts, they all believe that this gun is a groundbreaking product."

"At present, we are ready to organize the new production line to start production."

"However, there are some technical issues that I still need your help to solve."

Wang Haoran bowed and said, "No problem, just follow your instructions."

Wang Cunxian said: "I see that you used a lot of engineering plastics in the Type 77 rifle. The plastic you made in the laboratory has high strength, stable chemical properties, and good heat resistance and corrosion resistance."

"Experts say this is PPS polyphenylene sulfide. We don't have the conditions to mass-produce this material yet."

"Can you help us solve this problem?"

In fact, when Wang Haoran was drawing the comprehensive process design drawings of the Type 77 rifle, he had already written out the refining method of the engineering plastics used on the gun.

But laboratory manufacturing is obviously different from large-scale industrial mass production.

This must be taken into consideration.

In fact, Longguo's industrial production of engineering plastics began in the late 50s.

By the 60s, three major production bases had been built in Beijing, Shanghai and Liaoning Province.

After the emergence of PPS polyphenylene sulfide, Longguo began to develop and produce it in the early 70s.

However, the scale has always been relatively small, and the production method is not simple enough, mainly because the production equipment and process flow have not been properly processed.

This has clearly become a problem.

Wang Haoran naturally knew that engineering plastics were indeed a problem at present.

He had the ready-made mature production process of PPS polyphenylene sulfide in mind.

Just take it out.

In addition, Wang Haoran was also considering another issue: a war would break out in less than two years.

Should I also try to come up with some new weapons with more powerful lethality?
I need to talk this matter over with Wang Cunxian.

On that day, Wang Haoran followed Wang Cunxian to a firearms research institute under the Fifth Ministry of Machine Building.

The various research equipment here is more complete.

The director of the Firearms Research Institute is Sun Shitong.

As you can tell from the name, it means world peace.

Sun Shitong was very enthusiastic when he saw Wang Haoran.

"Hello, Comrade Haoran! I finally meet you, haha!" Wang Haoran exchanged a few polite words with the other party.

Then, everyone started to enter work mode.

Sun Shitong told Wang Haoran that the main obstacle to the mass production of the Type 77 rifle is engineering plastics.

Of course, a new bullet production line also needs to be built.

The ability to mass-produce standard bullets is also a symbol of industrial strength.

In fact, in 1977, Longguo already had a very strong industrial base.

At this time, industrial development is still carried out in a large-scale battle mode.

Once we are ready to make a breakthrough, we mobilize forces from all over the country.

Then try to get it done in the shortest time possible.

Therefore, at this time, it would not be difficult for Longguo to prepare to build a 5.8mm bullet production line.

If you are determined, there is nothing you can't accomplish.

Wang Haoran spent two days helping Sun Shitong solve the problems of mass production equipment and processes for PPS polyphenylene sulfide engineering plastics.

As long as this is done, there will be no problem in mass producing high-performance engineering plastics.

Sun Shitong said with emotion: "Comrade Haoran, thank you so much!"

"You are quite smart. In fact, we have been able to produce materials like PPS in the laboratory for a long time. But we just can't mass-produce it."

Wang Haoran smiled and waved his hand, saying, "You're too kind."

"By the way, you should be able to easily make other models of the Type 77 gun family, right?"

A standard weapon that is equipped on a large scale must appear in the form of a family of guns.

Wang Haoran didn't have that much time at the time, so he only drew the process drawing of the Type 77 automatic rifle. He had not yet designed the other guns in the family.

“We originally wanted to do it ourselves,” Sun said.

"But then I thought, what we do ourselves may not be consistent with your original design ideas."

"So, we hope to listen to your suggestions this time."

Wang Haoran said, "It's actually quite simple."

"My idea is to make sure all the guns in the family can share most of the parts."

"This will help improve production efficiency and reduce production costs."

Sun Shitong nodded and said, "This is a good idea. If it can be done, it will be quite groundbreaking!"

Next, Wang Haoran began to develop the Type 77 light machine gun and the Type 77 sniper rifle.

In fact, the biggest difference between the three is the barrel.

The light machine guns have slight differences in magazines.

In the previous life, the Type 95 light machine gun used a drum magazine, which was difficult to disassemble and was very heavy.

Machine gunners generally don't like to use this thing.

Therefore, in this life, the drum must be removed.

For the Type 77 sniper rifle, the main feature is to increase shooting accuracy and lengthen the barrel.

It took Wang Haoran more than an hour to draw the design drawings of the Type 77 squad light machine gun and sniper rifle.

Next comes the lab manufacturing process.

The production of prototype guns in the laboratory went relatively smoothly.

After it was built, various tests were carried out in the institute’s shooting range.

The performance of both guns is also amazing.

The Type 77 sniper rifle can even accurately shoot targets 1500 meters away, which is quite amazing for a small-caliber sniper rifle!
However, this is the result of Wang Haoran's transformation.
