Cams used in oil and gas or chemical processing applications convert rotary motion in the machine into reciprocating linear motion. D2 tool steel is critical to this application due to its hardness and corrosion resistance, and when the cam interacts mechanically with the sliding pin, it ensures a longer service life. In addition, since these components are usually integrated into machines operating in harsh environments, the corrosion resistance provided by D2 ensures that the components operate as expected and will not deteriorate.

D2 tool steel is a high-carbon, high-chromium air-hardening tool steel with a wide range of uses. It is characterized by high hardness and compressive strength after heat treatment. This tool steel also has extremely high wear resistance, dimensional stability and corrosion resistance under hardened conditions, which is a key advantage for conformal cooling applications. D2 is used for various cold work tools that require both wear resistance and medium toughness, such as stamping and sizing tool components, blanking and forming molds, shearing tools, gauges, polishing tools and other wear-resistant parts.

Jonah Myerberg, co-founder and chief technology officer of Desktop Metal, said: "Our materials science team has been committed to developing new materials and new processes to make 3D printing suitable for all industries and applications." "We are responding to customers in the manufacturing and industrial industries. There is a demand for materials such as D2 tool steel that can produce critical forming and cutting tools, as well as various other applications where high hardness is important."

Desktop Metal's material science team printed out qualified and fully characterized D2 tool steel on the production system technology according to ASTM test requirements.

Rotating cam cams used in oil and gas or chemical processing applications convert rotary motion in the machine into reciprocating linear motion. Usually, these parts require multiple manufacturing steps, starting with CNC machining and then broaching the splines on a separate machine. Adhesive jetting can produce cams in a single printing step, reducing part cost and delivery time, while also supporting the production of multiple sizes of cams in a single build to suit different machines, all without any fixtures or tools . D2 tool steel is critical to this application due to its hardness and corrosion resistance, and when the cam interacts mechanically with the sliding pin, it ensures a longer service life. In addition, since these components are usually integrated into machines operating in harsh environments, the corrosion resistance provided by D2 ensures that the components operate as expected and will not deteriorate.

Production System-The fastest way to 3D print metal parts on a large scale in the world

The production system created by the inventor of adhesive jetting and single-pass inkjet technology is an industrial manufacturing platform supported by Desktop Metal's SPJ technology. It aims to achieve up to 100 times the speed of traditional powder bed fusion additive manufacturing technology, and can produce up to millions of parts every year at a competitive cost compared with traditional mass production technology.

The production system platform consists of two printer models: P-1, a solution for process development and mass production applications, and P-50, a large-scale mass production solution for end-use parts. The production system combines desktop metal engineering adhesives with an open material platform, enabling customers to produce high-performance parts using the same low-cost metal powders used in the metal injection molding (MIM) industry. The inert processing environment is compatible with a variety of materials, including high-performance alloys and even reactive metal powders such as aluminum and titanium.

After pausing their social media chaos at the Ryder Cup, the gloves were apparently taken off again.

A subscriber asked Lithium Americas Corp., which is part of the VanEck Vectors Rare Earth/Strategic Metals exchange-traded fund.

(Bloomberg)-President Joe Biden's move to release supplies from U.S. oil reserves will flood the market with sour crude oil that refiners are currently avoiding. Bloomberg Asia’s richest man pays attention to the Walton family succession plan. The 24-year-old aims to overthrow Victoria’s Secret. New York City is building an oyster wall to withstand floods.

After President Joe Biden used strategic oil reserves in a move by five other countries to join, oil futures rose sharply. This is what is happening.

Biden hopes to provide American drivers with cheaper refueling, but oil-producing countries want prices to rise.

New data shows that as the Biden administration and its allies scramble to provide more oil to the market by releasing inventories, shale oil producers are putting the brakes on reinvestment. This is a sign of widening differences between American Petroleum Corporation and Washington. This restraint has become the latest point of friction between oil producers and the White House. On Tuesday, after efforts to persuade OPEC and US oil-producing countries to speed up production failed, US President Joe Biden coordinated with China, India, Japan and South Korea to release oil inventories.

Goldman Sachs analysts said that the coordinated release of government oil reserves led by the United States may increase the supply of crude oil by about 70 to 80 million barrels, which is lower than the market price of more than 100 million barrels. The bank said in a report entitled "A drop in the ocean": "According to our pricing model, such a release value will be less than US$2/barrel, which is much lower than the selling of US$8/barrel that has occurred since the end of October." November 23rd. After the United States and other consumer countries released oil from the Strategic Petroleum Reserve (SPR) in an attempt to cool the market, global oil prices rebounded to a one-week high on Tuesday, but failed to meet some expectations.

In the first executive decision part of last Friday's "Crazy Money" show, host Jim Cramer sat down with Nikesh Arora, chairman and CEO of network security giant Palo Alto Networks. Arora said that Palo Alto's recently announced first fiscal quarter was the best in five years, which proves that the company has finally begun to take cybersecurity seriously. According to research, Arora said that when a hacker discovers a vulnerability, you have up to five hours to patch it and protect yourself.

The U.S. pressured OPEC to increase oil production and cool down hot crude oil prices. This puts the producer group facing a relatively new problem: Even if it wants to increase production, it does not have much extra capacity to increase production faster. . However, OPEC cannot even achieve these goals. According to data from the International Energy Agency (IEA), OPEC’s September and October production was 700,000 barrels per day less than planned, which increased the prospect of tight markets and high oil prices.

Samsung said it plans to build a $17 billion semiconductor factory outside of Austin, Texas, in a global shortage of chips used in mobile phones, automobiles and other electronic devices.

The Democratic President announced the largest release in the history of what he called the US Strategic Petroleum Reserve to coordinate with other countries to increase domestic supply. The White House is also investigating possible illegal actions by oil and gasoline companies, saying that these companies are artificially raising natural gas prices.

As part of its efforts to reduce gasoline prices, the Ministry of Energy will release 50 million barrels of oil from the Strategic Petroleum Reserve.

Although Worthington Industries hopes to improve the product, the Environmental Protection Agency may let them eliminate it.

Launceston, Australia (Reuters)-For the first time in ten years, the construction of a large new liquefied natural gas (LNG) project in Australia has been approved, but the structure and market reality of the Scarborough project indicate that it is likely to be the last such project Woodside Petroleum and BHP Billiton finally supported a $12 billion plan on Monday to develop the Scarborough gas field near Western Australia and expand the onshore Pluto LNG plant to process fuel. The transaction also saw the merger of Woodside and BHP Billiton's oil division. BHP Billiton shareholders will issue new Woodside shares and eventually receive approximately 48% of the enlarged share capital.

Almost a month ago, Indian farmer Suresh Dhane harvested soybeans from an acre of land, but like millions of others, he has been keeping his crops instead of selling them to oilseeds Processors hope that prices will rise. Farmer sales have slowed down India’s oilseed crush and may force the country to increase imports of edible oils such as soybean oil, palm oil and sunflower oil, even though local soybean production is expected to increase by more than one-tenth from a year ago. “Last year, I sold the soybeans at 4,000 rupees ($53.70) per 100 kilograms immediately after harvesting them. A few months later, the prices soared to more than 9,000 rupees,” Dhane said while drying the soybeans outside his home.
