Trump, who could not raise enough money, was furious and scolded all night!

On the 18th, a lawyer for former US President Donald Trump told the court that Trump did not have enough cash to appeal against a $45.4 billion fine. Media analysts believe that this may lead to Trump facing asset forfeiture.

Rumors of imminent bankruptcy followed on the Internet, dealing a humiliating blow to Trump’s carefully crafted image of a self-made business tycoon.

Related terms such as Trump’s bankruptcy have been on the top search list of social media platform X.

That night, Trump cursed all night on his social media platform TS, posting more than a dozen posts in a row.

Trump’s fury was triggered by a lawsuit he lost that exaggerated his assets. On Feb. 16, New York State Supreme Court Justice Arthur Ngoren ruled that the Trump family had been granted loans and tax breaks by exaggerating their net worth for years, a move suspected of fraud and sentenced to a fine of $45.4 billion.

It is reported that Trump is appealing the outcome of the trial, but if he wants to continue the appeal and prevent New York from enforcing the verdict, he will need to pay the deposit in full, which is due at the end of March.

Even if there is more money, it will be difficult to come up with more than $400 million at once, not to mention the chances that Trump does not have so much liquidity. The New York Times recently calculated that Trump has about $3.5 billion in cash on hand, while most of his wealth is related to real estate investments.

Trump reportedly said he had contacted about 30 guarantees through four different brokers and spent countless hours negotiating with one of the world’s largest insurances. However, potential guarantees seek to get Mr Trump to pay cash so that they do not consider using Mr Trump’s assets as collateral for margin.

To make matters worse, earlier this month, Trump paid a $91.6 million deposit in an appeal against the Carroll libel case.

Therefore, it is a bit difficult to spend more than US $400 million.

In response, Trump complained in a post on social media on the 18th that the amount of the deposit was unconstitutional, unAmerican, unprecedented, and almost impossible for anyone (including anyone as successful as me).

Trump posted a short composition on social media after 6: 00 a.m. on the 19th.

It is precisely because it is impossible that Trump seems to have insomnia, scolding the relevant sentences and judges and prosecutors all night. I will be forced to mortgage or sell important assets and may be able to sell them at a low price, and even if I win the appeal, they will cease to exist, Trump said in the post. Does it make sense? it’s witch hunting, interfering in elections!

Trump also raised the impact of the case to a level that affected the New York state economy, saying bluntly that New York companies would be scared to run away when they saw the case.

If you scold, the problem must be solved. Analysts believe that there are several options in front of Trump.

First, the time given by prosecutors is not yet up, so Mr Trump still has time to sell assets quickly or seek help from wealthy supporters.

In addition, his lawyer has appealed to a higher court for a deposit of about $100 million. At the same time, New York State prosecutors may, out of tolerance, give the former president more time to raise money.

As Trump’s last card, he can also ask the Trump Organization involved in the case to file for bankruptcy, which will automatically suspend the verdict against the entity. However, Trump is running for the US presidential election in 2024, a politically worrying choice, and he is likely to be reluctant to file for bankruptcy because of the trauma left by Trump’s bankruptcy filing in the 1990s.

To say the least, filing for bankruptcy is not a panacea. Legal experts say seeking court protection could raise a series of new problems, such as the risk of default on his loans after filing for bankruptcy, which could further spark lawsuits over whether Mr Trump is still liable to repay his debts. About a week ago, Trump locked in the Republican presidential nomination in the 2024 election, and there are still about eight months to go, during which time the campaign expenses are not small.

If none of these options happens and Mr Trump is unable to raise the money, Mr Trump’s assets may indeed be confiscated after March 25.

　　The mold steel material used in mold parts processing has high hardness, and the mold processing equipment is required to have thermal stability and high reliability.At the same time, moulded plastic parts It is no longer a relatively unfamiliar industry, and it enters the public’s sight more and more frequently, gaining more attention and recognition. https://www.dghrjmmj.com

　　For complex cavities and multifunctional composite molds, as the shape of the parts becomes more complicated, the design and manufacturing level of the mold must be improved. Multifunctional composite molds that form or assemble multiple grooves and multiple materials in a set of molds require a large amount of processing programming, high deep hole comprehensive cutting ability and high stability, which increases the difficulty of processing. The processing quality of mold parts includes processing accuracy and surface quality: processing accuracy is the degree of conformity between the three geometric parameters of the actual size, shape, and position of the surface of the part after processing and the ideal geometric parameters required by the drawing; the deviation value between the actual geometric parameters of the part and the ideal geometric parameters is called processing error.

　　Processing accuracy and processing error are both terms for evaluating the geometric parameters of the processing surface. Processing accuracy is measured by tolerance grade. The smaller the grade value, the higher the accuracy; processing error is expressed by numerical value. The larger the numerical value, the greater the error. High processing accuracy means small processing error, and vice versa; the actual parameters obtained by any processing method will not be absolutely accurate. From the function of the part, as long as the processing error is within the tolerance range required by the part drawing, it is considered that the processing accuracy is guaranteed.

　　The quality of a machine depends on the processing quality of the parts and the assembly quality of the machine. The processing quality of the parts includes two parts: processing accuracy and surface quality. Machining accuracy refers to the degree to which the actual geometric parameters (size, shape and position) of the parts after processing are consistent with the ideal geometric parameters. The difference between them is called processing error. The size of the processing error reflects the level of processing accuracy. The larger the error, the lower the processing accuracy, and the smaller the error, the higher the processing accuracy; the main aspects that affect processing accuracy: dimensional accuracy, the degree to which the actual size of the part after processing is consistent with the center of the tolerance zone of the part size.

　　In the fastener forming process, cold heading (extrusion) technology is a main processing technology, which belongs to the category of metal pressure processing. In production, at room temperature, external force is applied to the metal to form the metal in a predetermined mold. This method is usually called cold heading. In fact, the forming of any fastener is not only achieved by cold heading. In the cold heading process, in addition to upsetting deformation, it is also accompanied by positive and negative extrusion, compound extrusion, punching, rolling and other deformation methods. Therefore, the name of cold heading in production is just a habitual name. To be more precise, it should be called cold heading (extrusion).However, with the development of the industry, non standard fasteners It will also bring us more and more consumer experiences, so that users can really feel the upgrade and change. https://jieruifasteners.com/

　　Cold heading (extrusion) has many advantages, and it is suitable for mass production of fasteners. Its advantages can be summarized as follows:

　　High steel utilization rate. Cold heading (extrusion) is a method with little or no cutting. For example, when machining hexagonal bolts and cylindrical hexagon socket screws of rod type, the steel utilization rate is only 25% to 35% by cutting method, while by cold heading (extrusion), its utilization rate can be as high as 85% to 95%, which is only some process consumption of material head, material tail and cutting hexagonal head edge.

　　High productivity. Compared with general cutting processing, the efficiency of cold heading (extrusion) is more than dozens of times higher.

　　Good mechanical properties. The strength of parts processed by cold heading (extrusion) method is much better than that of cutting processing because the metal fiber is not cut off.Suitable for automated production. Fasteners (including some special-shaped parts) suitable for cold heading (extrusion) method are basically symmetrical parts, suitable for production by high-speed automatic cold heading machine, and also the main method of mass production.

　　In short, the cold heading (extrusion) method for processing fasteners and special-shaped parts is a processing method with a very high comprehensive economic benefit. It is a processing method commonly used in the fastener industry. It is also an advanced processing method that is widely used and has great development both at home and abroad.

　　Cold heading, cold pressing:

　　At room temperature, the blank is placed in the mold of an automatic cold heading machine or a press, and pressure is applied to the mold. The relative movement of the upper and lower molds is used to deform the blank in the mold cavity, reduce the height, and increase the cross section. This pressure processing method is called cold heading for automatic cold heading machines and cold pressing for presses. In actual production, the cold forming process of fasteners is often accompanied by extrusion during the cold heading process. Therefore, the cold heading process of fastener products is actually a composite processing method that has both cold heading and extrusion.

　　Deformation methods of cold heading (extrusion):

　　1. Punching. Separate part of the blank from the main body, such as cutting of wire, punching of nuts, trimming of the head of hexagonal bolts, etc.

　　2. Upsetting. A processing method that shortens the height of the blank and increases the cross-section, such as ball upsetting of nuts, pre-upsetting and fine upsetting of bolt head forming, etc.

　　3. Positive extrusion. During cold heading, when the blank is deformed in the lower die, the flow direction of the metal is consistent with the movement direction of the upper die. The reduction of the thick rod in cold heading bolts and cylindrical head hexagon socket screws is a positive extrusion.

　　4. Reverse extrusion. During the deformation of the blank, the flow direction of the metal is opposite to the movement direction of the upper die. The head forming of the cylindrical head hexagon socket screw belongs to reverse extrusion.

　　5. Compound extrusion. During the deformation of the blank, part of the metal flow direction is the same as the movement direction of the upper die, and part is opposite to it, that is, there is both positive extrusion and negative extrusion during the deformation. For example, the cylindrical head hexagon socket screw has both rod diameter reduction (positive extrusion) and head forming (negative extrusion) during the deformation at the same station.
