Manufacturing

the answer is thermoplastics can be melted down and moulded into something different, hence why they are so easy to recycle. Where as thermosetting plastics cannot be melted down after it has already set.

This is due to the bonds in the hydrocarbon formula (plastics are made out of hydrocarbons, hydrogen and carbon atoms). Thermoplastics have an alkene bond which means the hydrocarbon shares an atom with two bonds making it more reactive; and hence easy to recycle. Thermosetting on the other hand has normal bonding.

Household products such as cleaning agents (detergents, soaps), personal care products (shampoos, lotions), paints, and adhesives may require viscosity testing during manufacturing to ensure they have the right consistency for proper application and performance. Ensuring the correct viscosity can also impact factors like shelf life and user experience.

Rubber bands are affected by temperature because they are made of polymers that become more rigid and less elastic at colder temperatures, and softer and more stretchable at higher temperatures. These changes in temperature can cause rubber bands to become brittle and break more easily in cold conditions, and stretch out and lose their elasticity in hot conditions.

A Net Smelter Royalty (or Net Smelter Return) is a royalty that is a certain percentage of the revenue generated by the mine by selling its product, minus the expenses of producing the product, usually with a limit on what can be deducted.

Most royalties include more deductions: the costs of building the mine and infrastructure, the cost of exploring to find the deposit, the cost of repaying the loans needed for construction, and so on. It's possible for a mine to operate for years (indeed, theoretically possible for it to go its entire lifetime if it;s not making much money) without paying a royalty.

Most examples of an NSR, on the other hand, either don't take those "sunk costs" into account, or have a limit on how much of them can be used as deductions.

Example:

A mine costs $200 million to build, paid for by bank loans (we'll ignore interest) that has to be paid back. The mine produces $100 million worth of product a year, and spends $50 million a year to produce it, netting them $50 million in net revenue (we'll also ignore taxes and other fees).

At $50 million a year net revenue, it will take them 4 years to pay back the loan, after which they will actually generate real profit. If there was a 10% government royalty, the money it would collect would look like this:

Years 1-4 - $0

Years 5-10 - $5 million a year, total $30 million.

If there was an NSR, the $200 million that has to be paid back is ignored; the NSR focuses only on what's sold versus expenses to sell the product. So if there was a 3% NSR, it would look like this:

Years 1-10 - $1.5 million a year (3% of $50 million), total $15 million.

While the 10% royalty sounds like a better deal, if the mine wasn't as profitable it wouldn't be. Imagine that the annual costs are $75 million: at $25 million gross revenue per year, it will take 8 years to pay back the loan (rounding up). In that case, the result would be:

10% Royalty

Years 1-8 - $0

Years 9-10 - $5 million a year, total $10 million

3% NSR

Years 1-10 - $1.5 million a year (3% of $50 million), total $15 million

The advantage of a normal royalty is that, when a mine is generating good revenue, the royalty will generate more income than an NSR. However, it may be some time before a royalty starts paying.

The advantage of an NSR is that while it can pay less than a royalty, it starts generating income immediately.

10.9 grade steel is a common type of high strength structural steel that is typically used in construction and manufacturing applications. The "10.9" refers to the minimum tensile strength in MPa, which is 1000 MPa for the 10 part and 900 MPa for the 9 part, making it a strong and durable material for various purposes.

when the amount of alumina in the hall heroult electrolytic cell decreases to a certain level then the voltage of the cell abruptly increases which leads to the failure of the cell.this effect is known as anode effect.

Provide evidence of your skills and experience through past projects or relevant accomplishments. Offer to take on a small project or task in the new area to demonstrate your capabilities. Emphasize your willingness to learn and adapt to new challenges.

Yes, there are still some companies that manufacture mp3 players in the USA, such as Astell & Kern and HiFiMan. However, many mp3 players are now produced overseas in countries like China and South Korea.

Iron is commonly used in construction for making steel, which is used in buildings, infrastructure, and vehicles. Additionally, iron is used in the manufacturing of household appliances, machinery, and tools. It is also an essential component of hemoglobin in red blood cells, helping transport oxygen throughout the body.

Acrylic plastic is typically made from methyl methacrylate monomer, which is a liquid compound derived from natural gas and petroleum. It can be produced through a process called polymerization, where the monomer molecules are chemically bonded together to form long chains, creating the acrylic plastic material.

Plastic as we know it today was first invented in 1907 by Leo Baekeland, who created Bakelite, the first synthetic plastic. However, the use of natural plastics dates back centuries, with materials like shellac and rubber being utilized for various applications.

Factors affecting aviation include weather conditions, airline regulations, fuel prices, government policies, technological advancements, and global economic factors. These elements can impact operations, safety, profitability, and overall performance in the aviation industry. Adaptability and strategic planning are vital for aviation stakeholders to navigate through these challenges.

Plastic syringes are typically manufactured by a process called injection molding. The machines used are called injection molding machines. These machines inject liquified plastic into a mold which is the shape of a syringe. When the plastic cools, it forms a syringe.

Cotton fabric is generally considered to be a lightweight fabric. Its weight can vary depending on the thickness of the weave and any additional treatments it may have undergone, but it is typically lighter than fabrics like denim or wool.

Hydroelectric energy would not be suitable in areas with low water availability or where there are no suitable water sources like lakes or rivers. Additionally, regions prone to droughts or with unstable water flow may not be ideal for hydroelectric energy generation.

A motion and time study involves observing and analyzing how a task is performed to improve efficiency. For example, timing how long it takes a worker to complete a specific assembly process and then identifying any unnecessary motions or steps that can be eliminated to streamline the task and reduce time.

Metals are typically extracted from ores through processes such as smelting and refining. First, the ore is mined and sorted to extract the metal-bearing materials. Then, it undergoes processing to remove impurities and isolate the desired metal, which can involve heating, chemical reactions, and electrolysis. Finally, the metal is further purified and shaped into its final form for commercial use.

No, SJ cord is only rated for 300 volts and is not suitable for use with 480 volts. It is important to use the correct voltage rated cord for safety and to prevent damage to equipment. Look for cords that are specifically rated for 480 volts.

-Nylon was the first man-made fabric to function as a synthetic substitute for silk. Now, as one of the strongest fabrics available, it is used in clothing, household goods, and other commercial and industrial products.

-Nylon was invented in the E. I. DuPont de Nemous & Company laboratory by the organic chemist, Wallace Carothers. He discovered the structure of natural polymers and used the information as the basis of his formula for synthetic polymers. He patented the fabric in 1935 and the first duPont nylon stockings became available for sale in the United States in 1939. Part of the original motivation for creating nylon was to produce a silk substitute, because of problems with importing Japanese silk into the United States at that time just prior to World War II.

Well, that all depends really. Let me share a real life story with you as I am an Independent IT Consultant.

A Customer of mine owns a sign and graphics shop. He is using a Dell home computer as his main production machine. It takes this machine literally 30-45 minutes or more to RIP the graphics (Generate and process them) to his $200K ish graphics printer that is capable of extremely fast printing. He does not see the benefits of having a machine that would RIP in less than 1 minute, but what he does see is the cost of such a machine.

Now, looking at this scenario, he "saved" about $1,500 on the computer, but over the course of the 3 years he has had it, what has it really cost him? Well if you calculate in that a normal work day is 8 hours and he has been wasting 1-2 hours a day at say a standard rate of $65/hour; you find that it is costing him $65-$130/day X 260 normal working days in a year = $16,900 - $33,800/year.

So you tell me if productivity is the same as Profitability or Cost Reduction. In my opinion, Cost Reduction is the lazy route Accountant's take to show CEO's how they are going to save a company money and make it more profitable, at least for the short term. What the hell, why not just have the electricity, gas, and all other expenses shut off and imagine all of the money the company will save.........

Pressure die casting is the term used when metal is forced under high pressure into a die casting mold or die. The die casting process in USA is "pressure die casting" but referred to simply as "die casting" refer to http://www.kineticdiecasting.com/what-is-die-casting.html

As of 2021, the cost of lanthanum is approximately $750-$800 per kilogram. The price can fluctuate depending on factors such as supply and demand, market conditions, and the purity of the lanthanum being sold.

If there was no wind resistance they would both hit the floor at the same time... however, and since such an atmosphere doesn't exist, (Wind resistance acting on cotton is greater because it has a greater surface area..) so iron will fall faster ... .
