Engel injection molding machine information   The history of injection molding machines follows a similar pattern to the narrative of the technology itself. The machine's first appearance in our story is as an all-metal, hand-operated hot die machine that could melt metal into ingots. The first known injection molding machine was invented by Roy Plank and Werner von Siemens in Germany in 1832, along with someone else, who we will probably never know. Plank and von Siemens were experimenting with platens that could be used in large-scale production of steam engines and other large machines when they discovered that they could apply molten metal under pressure through precisely controlled orifice openings. Their method of operation became known as the Plank process, or injection process (Die Jetztgestellung).This method was not described very clearly by either Jim Welch or Joel Engel on their respective blogs until recently (cite: http://injectionmoldmachine.com/joele...orkel-pl...

New Plastic MATERIALS Research   Pp pc pe plastic materials are a group of polymers that include, polypropylene, polyethylene, polystyrene and polyester. Plastic materials have been used in a wide range of applications in modern times. With the ability to withstand heat and electricity while retaining form they are ideal for making disposable cups and plates, bottles, toys and other items that can be reused after they are used once again. Plastics (polymers) are easily manufactured by a very varied chemistry, permitting many to be moulded into any shape and in most types of materials with little material loss. The plastics process has now become an immense industry at home, abroad and elsewhere. A large number of research papers are published every year in this area. New research about plastic materials provides new information to the use and manufacture of polymer additives for walls, floors and roofs. A new study from the US Department of Agriculture's National Institute of ...

  Plastic Materials  The plastic material category is composed of one ingredient – Polyethylene. This is the most commonly used lightweight plastic because it has a wide range of uses, ranging from cups to cutlery and even as an everyday grocery bag or storage container. Plastic material is the main raw material used in processing the plastic. If a dye is needed to color the plastic material, it can be added after molding. The thermoplastic polymers (TP) are processed by heating to temperatures above the glass transition temperature (Tg), then cooled and cooled. The addition of fillers or pigments to increase strength, structure, flexibility, or other properties are known as “combinatorial design” of plastic materials Plastic is an artificial polymer with high mechanical strength, light weight and durability. It can be used for many purposes such as construction material and fuel source Virgin polyethylene terephthalate (PET) is a rigid, transparent and lightweight material th...

  What is Plastic Plastic is a synthetic, substance of organic chemistry that can be produced from petrochemicals. Though many people think of plastic as a new invention, it has been around for only about 100 years. The word "plastic" derives from the Greek root plastics, which means "able to be shaped or molded" or "resilient". Plastic Material  The material in which this product is made of is called plastic. Plastic is an inert, synthetic polymer made from petrochemicals that can be poured or molded into various shapes and used as injection molding materials. It has been used for more than 50 years as a substitute for natural rubber, polystyrene and polyvinyl chloride (PVC). Plastic Chemical Plastics are polymers of the elements carbon, hydrogen and oxygen. They are the most widely used organic chemicals on Earth: the first synthetic plastic was a film of acrylonitrile butadiene (NBR).Fiberglass insulation is made from long, stringy cellulose fibers that...
