How can acrylic sheet be formed into different shapes?
Heating it and allowing it to assume the shape desired, usually involving a mold or guide. This is the simplified explanation of how all curved glass/acrylic items such as windshields are made.
Vacuum forming is a process where hot perspex is layed over a mould then the air between the mould and the perspex is sucked out.
When did clocks start to be made of plastic?
I would guess around 1950 when plastic record players, kid's toys, dolls and play dinnerware became popular. Domesticated synthetic household paint took off around 1947. I can remember almost all our toys were made of plastic in 1958. At the time, it did not seem noticable, but now as I look back-All the feminine toys were made of plastic or synthetics-even doll hair. The only things that were not of plastic, were my brother's Battery operated large movable airplane with lights, his baseball bats (and even those came in plastic soon after), and his BB gun and bicycle. Soon after 1958, sleds, water pistols, toy balls and face masks were all synthetic. Even skateboards, wagons and later HOTWHEELS for tots, became mostly plastic based.
What is an example of a national primary business?

Briefly discuss product and process layout with examples?
TYPES OF LAYOUT:
There are mainly three types of plant layout:
(a) Product or line layout
(b) Process or functional layout
(c) Fixed position or location layout
PRODUCT OR LINE LAYOUT:
In this type of layout the machines and equipments are arranged in one line depending upon the sequence of operations required for the product. It is also called as line layout. The material moves to another machine sequentially without any backtracking or deviation i.e the output of one machine becomes input of the next machine. It requires a very little material handling.
It is used for mass production of standardized products.
Advantages of Product layout:
· Low cost of material handling, due to straight and short route and absence of backtracking
· Smooth and continuous operations
· Continuous flow of work
· Lesser inventory and work in progress
· Optimum use of floor space
· Simple and effective inspection of work and simplified production control
· Lower manufacturing cost per unit
Disadvantages of Product layout:
· Higher initial capital investment in special purpose machine (SPM)
· High overhead charges
· Breakdown of one machine will disturb the production process.
· Lesser flexibility of physical resources.
PROCESS LAYOUT:
In this type of layout the machines of a similar type are arranged together at one place. This type of layout is used for batch production. It is preferred when the product is not standardized and the quantity produced is very small.
Advantages of Process layout:
· Lower initial capital investment is required.
· There is high degree of machine utilization, as a machine is not blocked for a single product
· The overhead costs are relatively low
· Breakdown of one machine does not disturb the production process.
· Supervision can be more effective and specialized.
· Greater flexibility of resources.
Disadvantages of Process layout:
· Material handling costs are high due to backtracking
· More skilled labour is required resulting in higher cost.
· Work in progress inventory is high needing greater storage space
· More frequent inspection is needed which results in costly supervision
FIXED POSITION OR LOCATION LAYOUT:
Fixed position layout involves the movement of manpower and machines to the product which remains stationary. The movement of men and machines is advisable as the cost of moving them would be lesser. This type of layout is preferred where the size of the job is bulky and heavy. Example of such type of layout islocomotives, ships, boilers, generators, wagon building, aircraft manufacturing, etc.
Advantages of Fixed position layout:
· The investment on layout is very small.
· The layout is flexible as change in job design and operation sequence can be easily incorporated.
· Adjustments can be made to meet shortage of materials or absence of workers by changing the sequence of operations.
Disadvantages of Fixed position layout:
· As the production period being very long so the capital investment is very high.
· Very large space is required for storage of material and equipment near the product.
· As several operations are often carried out simultaneously so there is possibility of confusion and conflicts among different workgroups.
I really hate to say this, since I was trained so long ago at AlliedSignal as a black belt and then as a Master black belt in product development. You shouldn't use Six Sigma today. Here are the problems that are most detrimental to using Six Sigma to your business. First, there is no concept for robust process or product design. There are just too many things you DO NOT want to reduce the variation. In fact often you want to do the opposite of what Six Sigma was based on is design products and processes where the spec limit is so wide, reducing variation buys you nothing. This is called robust engineers. Second, what six sigma project do you do. There is no mechanism within Six Sigma that does a really good job of aligning the project to a really important business initiative that will cause the company to leap frog the competition.

What is the qualification for six sigma course?
There is no certifying body for six sigma. Most people are satisified if they have a certification from a reputable consulting firm or a large corporation. They real test is can you use six sigma to solve process problems. Visit www.bmgi.org - there are some training courses there at no cost.
What raw materials is cotton made from?
Cotton is a plant. The seeds of the plant are contained in a roundish pod called a boll, and surrounded by a fibrous material. When immature, the bolls are green, and the fibrous material is wet. As the bolls mature, they turn black/brown, the fibrous material swells, and the bolls split open, after which the fibrous material dries. This is raw cotton. The raw cotton is removed from the bolls, and the seeds are separated by machinery in a cotton gin. The fiber is then compacted into rectangular bales, generally weighing around 500 lbs, wrapped in burlap and banded with metal straps. The bales are then shipped to be processed into cloth and other articles. The seeds can be processed into cotton seed oil, and the bolls are often used as compost or mulch.
What are the three overhead absorption rates?
As far as I know there is only an overhead absorption rate and a full absorption rate. The alternative being marginal costing.
There are 3 methods of absorption costing. These being Activity, Time and Efficiency but I'm not sure what you are asking exactly.
Were did nylon get it name from?
Nylon was first established by New York and London. It couldn't be decided what country should get the credit for this new material. The first two letters "n" and "y" stand for New York and the last three letters; "L", "O" and "N" are the first three letters of London. So it reads New york, London.
What is the manufacturing date of a model 38 smith and Wesson 38 spl j frame 5 shot?
Impossible to answer without a serial number.
What is the difference between a direct and indirect employee in manufacturing?
Those employees who are directly related in manufacturing process are regarded as direct employees whereas there are several susidiary services required like machine repairs etc. which are not directly related to production but are inevitable. Employees falling under this category are namely indirect employees.
What is One potential cause of Total Manufacturing Overhead Variance?
If the estimated materials, labor or overhead costs allocated for a manufacturing order is different from the actual cost of the MO then the potential result is a Manufacturing Overhead Variance.
What is the difference in thermal and constitutional supercooling in steel?
Thermal Supercooling occurs when an advancing planner solid liquid interface becomes unstable andtriggers a spike that will appear on the interface which will then grow into a cellular type structure.
While Constitutional Supercooling occurs due to compositional change, and results in cooling a liquid below its freezing point ahead of the solid liquid interface.
Why is the color of a product important?
The more aesthetically pleasing to the eye a product is, the more likely a potential customer is to buy it. For example, if a drink was pale brown in hue, some people may be put off by the colour.
Also, it is important because it may show off what chemicals have been used in it. Some products are naturally an off-putting colour, so E-numbers and other damaging chemicals are added.
What is the manufacturing year of a S and W 78G with serial number Q006078?
Models 78G and 79G are vintage models of air-powered pistols. Each model chambered either a .177 or .22 caliber pellet. The S&W G-series pistols were designed with attention to accuracy and weight in particular, making them idea in developing short-range marksmanship skills while using a less-penetrating, air-driven pellet as the projectile. However, as these vintage airguns were manufactured in the '70's (when the research behind American airgun technology was less sophisticated) there are several drawbacks, including the fact that each model can only chamber one pellet at a time, requiring reloading after each shot. Also worth noting is that, while each model uses small pellets driven by CO2 cartridges, an airgun is still a potentially dangerous weapon requiring attention to all the basic safety premises followed when using regular combustion-driven firearms.
