Tesla patents aluminum “spray quench” process for molecular-level strengthening
Tesla has submitted a patent that describes a new, more effective cooling process for manufacturing high-strength aluminum components to be used in its product line.
The patent entitled, “System and Method for Facilitating Pulsed Spray Quench of Extruded Objects”, describes a quenching process that aims to increase the strength, rigidity, and energy absorption of aluminum alloy components. A multi-way spray nozzle system would cool extruded aluminum with an atomized spray of liquid.
“A system includes a billet die at a proximal end configured to accept a billet and form an extrudate, a quench chamber located adjacent to the billet die for receiving the extrudate and comprising at least one pulsed width modulation (PWM) atomizing spray nozzle and a control module in communication with the at least one PWM atomizing spray nozzle and configured to independently control a liquid pressure, a gas pressure, a spray frequency, a duty cycle and flow rate of each at least one PWM atomizing spray nozzle,” reads the patent abstract.
Vehicles today use 6XXX aluminum alloys, which make up the front and rear bumpers, side and back steps, and knee bolsters of a car, the Kobelco Technology Review stated. Tesla also indicates within the patent that it uses 6XXX alloys for its vehicles. After these parts are extruded, they enter a quenching process, which is simply the process of cooling the metal after it has been heated.
Currently, Tesla utilizes a quenching process that involves cooling recently extruded aluminum alloys by soaking the parts in water. This process of quenching is recognized as “quick cooling.” While other cooling means are available, such as air cooling and furnace cooling, soaking the parts in water is the most time-effective method for automotive manufacturing.

However, Tesla’s patent recognizes the adverse effects that quick cooling aluminum alloy parts can have on the structural integrity of the metal. Quick-cooling can not only lead to deformation and warping of metal parts, but things can change chemically as well.
Magnesium silicide, or Mg2Si, is present in these aluminum alloy parts, and quick cooling them can inhibit the compound’s ability to set in the metal. Without the proper setting of Mg2Si by quick-cooling the aluminum alloy in water, the metal requires a higher extrusion pressure and becomes more sensitive to heat, according to Light Metals 2014. The combination of these two properties can effectively compromise the mechanical properties of the final product, making the frame of the vehicle lose strength through the manufacturing process.
Tesla plans to utilize a multi-way spraying system to cool extruded aluminum parts, eliminating the soaking process that is used by so many manufacturers of aluminum alloy. In the patent, the company describes a quenching system that would spray newly extruded metals at varying rates depending on the size of the part. Between one half-gallon and 10 gallons of water per minute would cool the metal in question.

Two pyrometers would be placed at both the proximal and distal ends of the quench chamber. These would hold the responsibility of maintaining the metal’s temperature through the quenching process. The pyrometers would communicate with the system to ensure proper cooling temperatures, making sure the aluminum does not cool too quickly, allowing the Mg2Si to set. In conjunction with the temperature control, spray frequency, liquid pressure, gas pressure, and flow rate will also be monitored to ensure maximum strength after extradition is complete.
Tesla’s recognition of the flaws in quick-cooling extruded metals indicates the company’s realization that increased strength of a car’s frame could improve with a more efficient cooling technique.
In the teardown of the Model Y, Sandy Munro complimented Tesla’s use of what he called the “aluminum rear crush plate.” The piece is located at the trunk hatch and is designed to fold in the event of a rear-impact. The part saves the sides of the body from being compromised in a crash, which can ultimately total the vehicle if the chassis bends excessively.

While the crush plate is durable and prevents excessive damage to the body of the Model Y, the quick-cooling process used during manufacturing could ultimately make the crush plate less sustainable than what it could be. Not to mention, the front bumper, rear bumper, side and back steps, and knee bolsters are also made of aluminum. Using a different cooling technique could eventually lead to an even safer Tesla vehicle, which already has many five-star crash safety ratings from several organizations located around the world.

Tesla investors will be shocked by Jim Cramer’s latest assessment
Jim Cramer is now speaking positively about Tesla, especially in terms of its Robotaxi performance and its perception as a company.

Tesla investors will be shocked by analyst Jim Cramer’s latest assessment of the company.
When it comes to Tesla analysts, many of them are consistent. The bulls usually stay the bulls, and the bears usually stay the bears. The notable analysts on each side are Dan Ives and Adam Jonas for the bulls, and Gordon Johnson for the bears.
Jim Cramer is one analyst who does not necessarily fit this mold. Cramer, who hosts CNBC’s Mad Money, has switched his opinion on Tesla stock (NASDAQ: TSLA) many times.
He has been bullish, like he was when he said the stock was a “sleeping giant” two years ago, and he has been bearish, like he was when he said there was “nothing magnificent” about the company just a few months ago.
Now, he is back to being a bull.
Cramer’s comments were related to two key points: how NVIDIA CEO Jensen Huang describes Tesla after working closely with the Company through their transactions, and how it is not a car company, as well as the recent launch of the Robotaxi fleet.
Jensen Huang’s Tesla Narrative
Cramer says that the narrative on quarterly and annual deliveries is overblown, and those who continue to worry about Tesla’s performance on that metric are misled.
“It’s not a car company,” he said.
He went on to say that people like Huang speak highly of Tesla, and that should be enough to deter any true skepticism:
“I believe what Musk says cause Musk is working with Jensen and Jensen’s telling me what’s happening on the other side is pretty amazing.”

Robotaxi Launch
Many media outlets are being extremely negative regarding the early rollout of Tesla’s Robotaxi platform in Austin, Texas.
There have been a handful of small issues, but nothing significant. Cramer says that humans make mistakes in vehicles too, yet, when Tesla’s test phase of the Robotaxi does it, it’s front page news and needs to be magnified.
He said:
“Look, I mean, drivers make mistakes all the time. Why should we hold Tesla to a standard where there can be no mistakes?”
It’s refreshing to hear Cramer speak logically about the Robotaxi fleet, as Tesla has taken every measure to ensure there are no mishaps. There are safety monitors in the passenger seat, and the area of travel is limited, confined to a small number of people.
Tesla is still improving and hopes to remove teleoperators and safety monitors slowly, as CEO Elon Musk said more freedom could be granted within one or two months.

Tesla gets $475 price target from Benchmark amid initial Robotaxi rollout
Tesla’s limited rollout of its Robotaxi service in Austin is already catching the eye of Wall Street.

Venture capital firm Benchmark recently reiterated its “Buy” rating and raised its price target on Tesla stock (NASDAQ: TSLA) from $350 to $475 per share, citing the company’s initial Robotaxi service deployment as a sign of future growth potential.
Benchmark analyst Mickey Legg praised the Robotaxi service pilot’s “controlled and safety-first approach,” adding that it could help Tesla earn the trust of regulators and the general public.
Confidence in camera-based autonomy
Legg reiterated Benchmark’s belief in Tesla’s vision-only approach to autonomous driving. “We are a believer in Tesla’s camera-focused approach that is not only cost effective but also scalable,” he noted.
The analyst contrasted Tesla’s simple setup with the more expensive hardware stacks used by competitors like Waymo, which use various sophisticated sensors that hike up costs, as noted in an Investing.com report. Compared to Tesla’s Model Y Robotaxis, Waymo’s self-driving cars are significantly more expensive.
He also pointed to upcoming Texas regulations set to take effect in September, suggesting they could help create a regulatory framework favorable to autonomous services in other cities.
“New regulations for autonomous vehicles are set to go into place on Sept. 1 in TX that we believe will further help win trust and pave the way for expansion to additional cities,” the analyst wrote.
Tesla as a robotics powerhouse
Beyond robotaxis, Legg sees Tesla evolving beyond its roots as an electric vehicle maker. He noted that Tesla’s humanoid robot, Optimus, could be a long-term growth driver alongside new vehicle programs and other future initiatives.
“In our view, the company is undergoing an evolution from a trailblazing vehicle OEM to a high-tech automation and robotics company with unmatched domestic manufacturing scale,” he wrote.
Benchmark noted that Tesla stock had rebounded over 50% from its April lows, driven in part by easing tariff concerns and growing momentum around autonomy. With its initial Robotaxi rollout now underway, the firm has returned to its previous $475 per share target and reaffirmed TSLA as a Benchmark Top Pick for 2025.

Tesla blacklisted by Swedish pension fund AP7 as it sells entire stake
A Swedish pension fund is offloading its Tesla holdings for good.

Tesla shares have been blacklisted by the Swedish pension fund AP7, who said earlier today that it has “verified violations of labor rights in the United States” by the automaker.
The fund ended up selling its entire stake, which was worth around $1.36 billion when it liquidated its holdings in late May. Reuters first reported on AP7’s move.
Other pension and retirement funds have relinquished some of their Tesla holdings due to CEO Elon Musk’s involvement in politics, among other reasons, and although the company’s stock has been a great contributor to growth for many funds over the past decade, these managers are not willing to see past the CEO’s right to free speech.
However, AP7 says the move is related not to Musk’s involvement in government nor his political stances. Instead, the fund said it verified several labor rights violations in the U.S.:
“AP7 has decided to blacklist Tesla due to verified violations of labor rights in the United States. Despite several years of dialogue with Tesla, including shareholder proposals in collaboration with other investors, the company has not taken sufficient measures to address the issues.”
Tesla made up about 1 percent of the AP7 Equity Fund, according to a spokesperson. This equated to roughly 13 billion crowns, but the fund’s total assets were about 1,181 billion crowns at the end of May when the Tesla stake was sold off.
Tesla has had its share of labor lawsuits over the past few years, just as any large company deals with at some point or another. There have been claims of restrictions against labor union supporters, including one that Tesla was favored by judges, as they did not want pro-union clothing in the factory. Tesla argued that loose-fitting clothing presented a safety hazard, and the courts agreed.

There have also been claims of racism at the Fremont Factory by a former elevator contractor named Owen Diaz. He was awarded a substantial sum of $137m. However, U.S. District Judge William Orrick ruled the $137 million award was excessive, reducing it to $15 million. Diaz rejected this sum.
Another jury awarded Diaz $3.2 million. Diaz’s legal team said this payout was inadequate. He and Tesla ultimately settled for an undisclosed amount.
AP7 did not list any of the current labor violations that it cited as its reason for
