Delta Plastics‚ Inc. Delta Plastics‚ is a company that designs and manufactures plastic containers for household and kitchen use. The R&D group working for Delta is constantly thinking of new ways to develop‚ design and produce new plastic materials for the company. The new containers that the R&D group is currently working on are designed to be able to be removed from the oven and immediately stored in the refrigerator if necessary‚ with no wait time to cool. The group will be looking to see

Background The overuse of plastics in today’s society has become major environmental issue for our oceans. Plastic pollution is the dumping‚ littering‚ or disposing of any type of man-made plastic that has been produced and has ended up in our ocean and has not been recycled. History of Plastic "Plastic" entered the world through chemistry in 1909 and was originally coined to describe Bakelite‚ the first fully synthetic resin. What make’s plastic so unique is when it is heated it can be molded

September 26 we toured PCPM. I found out they specialize in plastic injection molding and have been in business since 1978. At the beginning of the tour we were informed on the process the plastic goes through from the time it enters the factory in pellets to the time it leaves as a finished product. When we actually toured the factory it was difficult to hear our tour guide but I believe heard him say they add nylon to the plastic for certain molds to make it stronger. Seeing the molding process

how many reusable bottles to order from Greaves Brewery’s German glass supplier. The decision this year is complicated by the possibility that a new bottle design could be introduced that would make all existing bottle inventories obsolete. In the past‚ however‚ Benson had delayed production by not ordering enough bottles to keep up with demand. The case provides an opportunity to employ a number of forecasting methods and the challenge of integrating the forecast with the bottle purchase-quantity

ADVANTAGES Plastic is very useful in the building and construction‚ electronics (laptops wouldn’t work well if they were made from glass)‚ packaging (gladwrap)‚ transportation industries. Very easy to make - water bottles‚ plastic bags‚ pens‚ cups etc etc The main advantages of plastic materials are also the reason why plastic is such a problem. It lasts forever and it is very cheap to make. When I say it last forever‚ I mean it does not biodegrade. There is a flotilla of plastic the size

Plastics are synthetic substances produced by chemical reactions. Almost all plastics are made from petroleum‚ except a few experimental resins derived from corn and other organic substances. "Plastics" derived their name from their properties to be molded‚ cast‚ extruded or processed into a variety of forms‚ including solid objects‚ films and filaments. These properties arise from their molecular structure. Plastics are polymers‚ very long chain molecules that consist of subunits (monomers) linked

plastic pollution‚ the accumulation in the environment of man-made plastic products to the point where they create problems for wildlife and their habitats as well as for human populations. In 1907 the invention of Bakelite brought about a revolution in materials by introducing truly synthetic plastic resins into world commerce. By the end of the 20th century‚ however‚ plastics were found to be persistent polluters of many environmental niches‚ from Mount Everest to the bottom of the sea. Whether
