Live Stream 1980: Netizens Teach Me How to Make a Rocket by Hand

Just then, the office door deep inside the workshop opened.

Wang Bin came out wearing a military overcoat.

He looked somewhat tired.

After the launch of Red Star 2, various data still need to be processed and archived.

Seeing the standoff, Wang Bin frowned:

"Old Chen, what's going on?"

"Director, you've come at the perfect time."

Master Chen pointed to the aluminum mold,

"These guys want to use aluminum molds for injection molding!"

"Isn't this just wasting the machine?"

"I'm too scared to drive it."

Wang Bin's gaze fell on Lin Xi.

Then, without making a sound, he glanced at Wang Yu, who was hiding at the very back.

"Lin Xi, are you confident?"

Wang Bin's voice wasn't loud, but it carried a sense of pressure.

"This machine is used to make insulation components for satellites."

"If it breaks, you couldn't afford to pay for it even if you sold your service center."

"Director Wang, I'm confident."

Lin Xi stepped forward, her eyes resolute.

"Aluminum molds are indeed soft, but as long as the parameters are controlled properly,"

"Not only will it not break, but it can also achieve a mirror-like effect."

Wang Bin stared at Lin Xi for a full three seconds.

"Old Chen, let him try." Wang Bin waved his hand.

"I'll be watching from the sidelines; if anything happens, it's on me."

Since the director had spoken, Master Chen couldn't say anything more.

He snorted and directed Wang Dapao to hoist the mold up.

He was still muttering to himself:

"Young people these days are so arrogant and ignorant..."

After the mold was installed, Wang Yu quickly poured the white, dried ABS granules into the hopper.

"How do I set the parameters?"

Master Chen placed his hand on the control panel and asked impatiently,

"Should I set the clamping force to the minimum?"

"Should we reduce the injection pressure to 50?"

"No."

Lin Xi took out a piece of paper from her pocket, speaking calmly.

"Clamping force 35 tons."

"First stage injection pressure 110, second stage holding pressure 85."

"Rate of fire 95%, pressure holding time 2.5 seconds."

"Cooldown time: 15 seconds."

"How many?!"

Master Chen's hand trembled violently, and he looked at Lin Xi as if she were a madman.

"Injection pressure 110?"

"95% rate of fire?"

"Are you trying to shoot through the mold?!"

"Could the aluminum mold withstand such a large impact?"

Such radical parameters require even the steel mold to be handled with extreme care.

This kid actually dared to use it on aluminum molds?

This is like driving a tractor and drifting on the highway!

Even Wang Bin, who was standing next to him, raised an eyebrow.

"Lin Xi, are you sure?" Wang Bin asked in a deep voice.

"Sure."

Lin Xi pointed to the temperature control gauge on the machine.

"ABS material has the best fluidity at 230 degrees Celsius, but aluminum molds dissipate heat extremely quickly."

"If we don't shoot quickly, the material will cool down halfway through, and the product will be undercooked."

"High pressure and high speed are required to fill the cavity with plastic within 0.5 seconds."

"Then, the high thermal conductivity of aluminum is used to instantly cool and shape it."

"This is called—in all martial arts, speed is the only thing that cannot be broken."

Master Chen, furious, laughed coldly: "Fine! Fine!"

"You want to destroy the mold, right?"

I'll grant your wish!

Although that's what he said.

But as she typed in the parameters, she still subconsciously glanced at Wang Bin.

Seeing that Wang Bin did not stop him, he gritted his teeth and pressed the start button.

"Buzz—"

The hydraulic pump emitted a dull groan.

Everyone held their breath.

Wang Dapao clenched his fists, his palms sweating profusely.

Screw propulsion, high-pressure injection.

"Bang!"

A dull thud.

That was the sound of high-pressure melt instantly filling the mold.

Master Chen subconsciously closed his eyes, waiting for the crisp sound of the mold shattering.

one second.

two seconds.

There was no explosion.

It did not break.

The only sounds were the steady hum of the machine running smoothly and the ticking of the cooling timer.

Master Chen suddenly opened his eyes and stared intently at the mold-locking mechanism.

As stable as Mount Tai!

"drop--"

After cooling is complete, the mold is opened.

"Click".

As the thimble moved, a grayish-white fan blade appeared.

Still warm from the previous day, it glided lightly into the receiving tray.

Master Chen grabbed the fan blades, ignoring the heat, and brought them close to his eyes to examine them closely.

No cloak.

There was no reduction in size.

The break at the flow channel opening was clean and crisp.

The most terrifying thing is the surface—

Its smoothness was like that of a mirror.

It reflected Master Chen's shocked and distorted face!

"This...how is this possible?"

Master Chen took off his gloves and gently stroked the surface of the fan blades with his fingertips.

Aluminum mold?

Is this made from an aluminum mold?

This quality is even better than the satellite parts he made using imported steel molds!

"Amazing..."

Master Chen muttered to himself, his gaze towards Lin Xi changing.

"Young man, your parameters... are pretty impressive."

"show me."

Wang Bin, who had been silent all along, walked over and took the fan blade from Master Chen's hand.

He didn't check the smoothness or whether there were any rough edges.

As a top aerodynamics expert, his focus was on the shape of the fan blades.

Those are not ordinary flat blades.

It was an extremely complex hyperbolic variable cross-section design.

The leaves are thick at the base and thin at the tip, with a strange twisted angle.

"NACA 4412 airfoil..."

Wang Bin squinted, his fingers gently tracing the edge of the leaf.

"This design is usually only used in..."

"On a propeller-driven fighter jet."

He looked up, his eyes sharply fixed on Lin Xi: "Did you come up with this?"

Lin Xi's heart skipped a beat.

Oops, I overdid it.

This silent fan blade design for 2025 is indeed a bit ahead of its time.

"Uh..." Lin Xi's mind raced, and a simple, honest smile appeared on his face.

"that……"

"I flipped through an old foreign journal in the library called 'Nonlinear Fluid Dynamics'."

"There was a similar picture above, so I just copied it..."

"In addition..."

"My master craftsman is skilled; he made it for the car."

"Nonlinear Fluid Dynamics?" Wang Bin nodded thoughtfully.

"That's a Soviet theory."

No wonder.

Although this explanation is far-fetched, it is actually the most reasonable for a tech fanatic like Wang Bin.

He looked at the fan blades in his hand again, but this time, his focus was no longer on the fan itself.

"High temperature, high pressure, rapid molding..." Wang Bin muttered to himself.

"Aluminum molds have fast thermal conductivity and high crystallinity, which actually increases their strength..."

Suddenly, Wang Bin's eyes lit up.

That was a problem that had been troubling him for half a year—

The internal structural support of the Red Star-3 satellite.

If this process were used to replace the bulky metal parts with this high-strength engineering plastic...

You can lose at least 30% of your weight!

In the aerospace field, one gram is equivalent to one gram of gold!

Lin Xi's seemingly childish "fan-making" inadvertently broke through a layer of window paper for him!

"Lin Xi".

Wang Bin's voice suddenly became serious.

Even when speaking to his subordinates, he never used such an almost equal tone.

"Compile these process parameters into a document and submit it to me tomorrow."

"in addition……"

Wang Bin paused for a moment, then took a notebook out of his shirt pocket.

With a "rip," a piece of paper was torn off, and a few lines of text were quickly written.
