78: Bringing his wife and children to Harbin Institute of Technology

Chapter 130 Clash

The applause gradually subsided, and then the host went on stage to ask:

"Anyone else have a question?"

A middle-aged man wearing glasses in the front row raised his hand.

Liu Xiaojun saw someone raise their hand and said:

"Please speak."

The middle-aged man pushed up his glasses and said:

"Comrade Liu Xiaojun, the motor of your mixer is old, the speed controller is modified by yourself, and the dispersion disc is outsourced. How can you guarantee the long-term stability of this non-standard equipment? In other words, what will you do if it breaks down?"

After listening, Liu Xiaojun, who had asked Zheng Shuyun this question before, smiled and said:

"I have a backup. I also modified the old mixer. The parameters are the same, so it can be used anytime."

"What if both of them break?"

Liu Xiaojun thought for a moment, then spoke:

"No, the motor is from Shenyang Motor Factory, it's high quality. I connected the circuit myself, and I tightened every terminal. I have twenty rubber pads in stock, that's enough. Even if it breaks, I can fix it within two days."

After answering the question, the middle-aged man didn't ask any more questions.

At that moment, someone else raised their hand on the right.

"Have you considered standardization in your renovation plan? In other words, can other factories replicate it?"

Liu Xiaojun thought for a moment, then answered slowly and deliberately:

"Yes, we can, but we haven't written it out yet. Professor Zhou said it can be written into an industry standard, and we are preparing it."

People below started whispering and discussing it.

A moment later, a young female teacher on the left raised her hand.

"Comrade Liu Xiaojun, I have a question about the data. You said the impact strength increased by 34%. Was this data measured under laboratory conditions or under mass production conditions?"

Liu Xiaojun glanced at Chen An below the stage.

Chen An nodded to him, and Liu Xiaojun said confidently:

"Tested under mass production conditions, three batches of twenty samples were randomly selected for inspection, and all passed. The original records are in the test report and can be viewed at any time."

The female teacher nodded and didn't ask any more questions.

The room remained quiet for a long time, and no one raised their hand to ask a question.

Just as Liu Xiaojun thought it was over, another person in the back row raised their hand.

He was an elderly man with gray hair, wearing a dark gray jacket, and instead of a school representative badge, he wore a guest badge.

"Young comrade, I have a question."

His voice wasn't loud, but it was very steady.

Liu Xiaojun looked at him, suddenly a little nervous, and said:

"Please ask."

"How much did you spend on this renovation?"

"The motor cost twenty yuan, the rubber pads were free (found at a scrap yard), the speed controller parts were salvaged from scrapped equipment, and the dispersing disc was processed by the school for free. In total, it cost less than fifty yuan."

Some people below gasped when they heard the cost.

The older comrade nodded as he looked at Liu Xiaojun on the stage.

"Fifty dollars to increase the impact intensity by thirty-four percent, do you think it's worth it?"

No one spoke in the meeting room.

The veteran answered it himself.

"It's worth it, so worth it!"

"I worked at the Commission of Science, Technology and Industry for National Defense for forty years. During the most difficult times, we used these rudimentary methods to produce things. If we didn't have the conditions, we created them; if we didn't have the equipment, we made the equipment ourselves."

He glanced at Liu Xiaojun on the platform.

"This young comrade from your Hongqi Factory has a lot of drive. We technicians are afraid we don't have that kind of drive."

The meeting room was silent for a few seconds.

Then someone applauded.

This time, more people applauded than before.

Liu Xiaojun stood on the stage, his eyes a little red.

He bowed deeply to the audience and began to speak:

"Thank you, teachers. Thank you for your recognition."

............................................

Liu Xiaojun stepped off the stage and sat back down next to Ye Bingwen, his hands still trembling.

Ye Bingwen patted him on the shoulder.

"Well said."

Liu Xiaojun took a deep breath and remained silent.

Chen An handed over the notebook.

"I wrote down all the questions the experts and professors asked, and we can compile them into a Q&A booklet when we get back."

Liu Xiaojun glanced at it; the entire page was filled with dense notes.

"So many?"

"Seven questions, not many."

The afternoon meeting has ended.

The organizers arranged a dinner party in the evening.

The three of them arrived at the restaurant together for dinner, and there were already quite a few people inside.

Ye Bingwen and his two companions found a table in the corner and sat down.

Liu Xiaojun sat next to him, still thinking about what happened that afternoon.

"Uncle Ye, who is that old comrade?"

"I don't know, there was no introduction."

"What he said was really inspiring."

Just then, the old man came over carrying a plate.

Is this seat taken?

Ye Bingwen stood up.

"No, please have a seat."

The old man sat down and placed the plate on the table.

"Where is your Hongqi Factory located?"

Harbin.

"How long have you been working on carbon fiber?"

"It's been less than a year, but our process parameters have been fixed, and mass production has been successfully implemented."

The old comrade nodded.

"I was really touched when I heard about your mixer. It's only fifty yuan, but many people these days are unwilling to put in the effort and thought that's necessary."

He looked at Liu Xiaojun.

"Young man, did you come up with that rubber pad idea yourself?"

Liu Xiaojun nodded.

"After trying it a few times, I found that adding pads stopped the shaking. Later, after learning about vibration theory, I realized it was due to the principle of shock absorption."

The old man smiled and then said.

"You're on the right track: practice first, then theory."

He turned to look at Ye Bingwen.

"Are you the factory manager?"

"Yes, comrade, my name is Ye Bingwen."

How old are you?

"I'm a sophomore now."

The older man was visibly taken aback for a moment, then smiled and nodded repeatedly.

"He became a factory manager in his sophomore year of college. Was he from Harbin Institute of Technology?"

"Yes."

"What major should you study?"

Mechanical Engineering.

The old comrade nodded.

"Besides mixers, what else does your factory have?"

"We have our own carbon fiber layup process, which has increased daily output by 50%. The phenolic resin toughening formula is developed by ourselves, and the impact strength is 34% higher than the national standard. We dug vibration isolation trenches in the equipment layout, which reduced the vibration error from 0.8 microns to 0.08 microns."

The older comrade listened in silence for a while before speaking again.

"Your factory isn't very big, but you've done a lot of work."

He took out a business card and handed it to Ye Bingwen.

"This is my business card. When you get back, please compile a copy of your project information and send it to me."

Ye Bingwen took the business card, which read "Commission of Science, Technology and Industry for National Defense, Wang Jianguo".

"Director Wang..."

"Don't call me Director, just call me Lao Wang."

Then Wang Jianguo stood up and left.

Liu Xiaojun approached, looking quite puzzled.

"Uncle Ye, what does the Commission of Science, Technology and Industry for National Defense do?"

Ye Bingwen looked at the business card.

"In charge of national defense scientific research."
