Handbook of Manufacturing Processes
Market/Audience This book is intended for Manufacturing and Process Engineers, Manufacturing Managers and all staff members with manufacturing responsibilities, as well as individuals who interact with manufacturing operations, including Salespersons and Sales Managers, Consultants, Government Regulators, Purchasing Agents, Quality Control and Maintenance Personnel. Also appropriate for anyone with interest in how products are made. Public and college libraries should have this book in their reference collections. General Purpose and Description Far more ambitious than any similar reference, the Handbook of Manufacturing Processes is an in-depth compilation of the workings of more than 1500 manufacturing processes in the metalworking, chemicals, textiles, plastics, ceramics, electronics, wood, and food industries; as well as a wide-ranging presentation of how more than 600 important products, components, and materials are made. Logically organized in two sections - a process section, and a products section - it describes clearly and succinctly the operations performed in the world's factories. Heavily illustrated, it is an extraordinarily comprehensive source of technical manufacturing information. Manufacturing and process engineers, factory managers and supervisors, and anyone who has an interest in or needs to know about manufacturing operations and how products are made - including those who are not technically trained - will find in this book a treasure trove of useful information. Distinctive Features

Welcome!
This is your part of this web site. Please enter your comments and questions. Particularly, if you know of some product, component or material, in which you would like to know how it is made in production, just ask us and we will endeavor to research the question and tell you. If you know how certain items are made and want to tell the world how it is done, this is your chance to do so. If you have other comments, gripes or complaints about the state of manufacturing in the world, or your part of it, particularly the operations within the factory, this is your chance to blow off steam. We want to hear from you! UPDATE: Due to excessive spamming, we are eliminating the forum in favor of a simpler eMail system. If you wish to post a comment or ask a question, please send me an eMail. My eMail address is "Jim" at this domain (which is "HowTheyMakeThings.com") So the eMail address would be: "Spammer@HowTheyMakeThings.com", except replace the word "Spammer" with "Jim".

Do You Know What You Are Eating? November 22, 2008 Some common prepared foods include some interesting
ingredients, whose source we may be unaware of. Are you a candy freak like me?
Do you eat M & M's or jelly beans? Do you chew gum? All have major
ingredients that, if they were served individually, you probably wouldn't want
to eat. Please post a comment or ask a question: Send an eMail to "Jim" at this domain "HowTheyMakeThings.com"
How They Make Things - Alkylate by Jim Bralla February 16, 2008 Alkylate, a chemical mixture that is a
by-product of petroleum refining, may become much more widely known in the
next few months. Its manufacture is discussed briefly on page 467 of the
Handbook of Manufacturing Processes. Its notoriety will come from several
factors: When used as an additive in gasoline, it raises the octane level
(anti-knock properties) of the gasoline, and it does not have the potential
undesirable environmental effects as does the more common octane-raising
additive, MTBE (methyl tertiary butyl ether). MTBE is a carcinogen and can
be absorbed into water. In some areas, it has been found in ground water,
raising safety concerns. Alkylate, and its key ingredient, isooctane, are
not water-soluble and do not have this problem. For that reason, in summer
months, alkylate replaces MTBE as an octane-controlling element in the
blends of gasoline shipped from refineries. Please post a comment or ask a question: Send an eMail to "Jim" at this domain "HowTheyMakeThings.com"
The Ubiquitous Glycerin
If consumers knew, or took the time to read the fine print list of ingredients in common household products such as toothpaste, mouthwash, shaving cream, skin and hair products, drugs, cough syrups, foods (candies, cakes, cheese), animal feeds, soaps and paints, they would know that glycerin (sometimes called glycol) seems to pop up everywhere. Even less noticeable to the consumer is its major use: as a raw material in the production of alkyd plastics. It is used in the consumer products because it has the desirable properties of absorbing and holding moisture, acting as a sweetener, solvent or softening, filling or thickening agent. It has been in the news recently because unscrupulous Chinese manufacturers have substituted the cheaper diethylene glycol for glycerin. Besides being cheaper, diethylene glycol is toxic to humans and over 100 people died in Central America when they used a cough syrup that contained dietheylene glycol. And recently, toothpaste containing this dangerous ingredient has appeared in the United States. Manufacturers were able to make the substitution of ingredients because the common test used in identifying glycerin in a mixture of materials registers the same whether the ingredient really is glycerin or diethylene glycol. The Chinese government, in defending it own industries, has stated that diethylene glycol is NOT poisonous, but there is no doubt that it is. Glycerin can be made in a number of ways. Originally, it was obtained as a bi-product in the manufacture of soap from vegetable and animal fats and about 40% is still made this way. The major production involves petroleum, in which it is synthesized from propylene (C3H6)or allyl alcohol (C3H6O). Another method utilizes the catalytic reaction of hydrogen and sugar at high pressure and temperature. It can also be made with a fermentation process. Diethylene glycol, on the other hand, is strictly a petrochemical. It is a bi-product in the production of ethylene glycol which is used extensively as anti-freeze. Ethylene glycol is made from ethylene oxide which, in turn, is produced from the gas, ethylene. (The production of ethylene is discussed on page 668 of the Handbook of Manufacturing Processes.)
Three materials that we didn't previously hear much about have been in the news lately. They are ethanol, wheat gluten and melamine. Ethanol is another name for ethyl alcohol, which is sometimes also called grain alcohol. It is the alcohol that is contained in beer, wine and other alcoholic beverages. With the name ethanol, heard lately from President Bush, it is a substitute for gasoline and can be a means for lessening America's dependency on crude oil and the products, such as gasoline, made from it. The manufacture of ethanol is discussed on page 623 of the Handbook of Manufacturing Processes. It is made from the fermentation of sugars and starches. When not used in an alcoholic beverage, it must be "denatured" by law to prevent its use as a beverage. See page 623. Wheat gluton is used as a food additive to provide more protein in vegetable-based foods. One common use is in pet foods and it made the news recently because contaminated gluten found its way into a number of commercial pet foods. Wheat gluten is made from the germ of wheat and manufacture is described on page 488. Melamine is most common as a major ingredient in melamine-urea plastic. The plastic is thermosetting and is perhaps best known when used to make "Formica" counter tops. It is also used as a coating and in handles, knobs and dinner plates. Melamine, when reacted with formaldehyde in making plastic, is highly inert, and, in the unreacted state is not classified as being hazardous to humans but apparently it can be to some animals, and, when used in pet food to simulate proteins, caused problems. Melamine production is found on page 771 of the handbook.
