What is the process used in injection molding?
Go to wikipedia and look up injection molding. You can also try www.mozdex.com/injection-molding-basics. Injection molding involves first having an injection molding machine. Second you must choose what shape you want to create, and have it drawn by a mechanical engineer. Then you must have the dies made at a machine shop to your specifications. Third you must select the type of plastic you want to make it out of, and set up your injection molder accordingly, and set it to run.
When was the sewing machine patented?
In 1846, Elias Howe patented the first sewing machine.
When was the first sewing machine patented?
1869
How do I use injection molding?
The injection molding process requires the usage of an injection molding machine, raw plastic material, and a shape. The plastic is liquefied inside the injection molding machine at that point injected into the shape, where it cools and solidifies into the definitive part.
What toy company is famous for using injection molding?
Almost all solid plastic toys manufactured today are made using injection molding. It is unclear that any one toy manufacturer is particularly famous for using this technique. Injection molding was first developed for use in other industries, and later spread to the toy industry.
How do you calculate the length of injection molding zones?
Runners and Gates are determined by the design of the part being molded and the size of the injection molded machine and is best left to molder's tool maker to determine and usually fine tune during the first run of parts
Does injection molding use high energy levels?
yes, whatever is injected is melted first
What is the keyword for plastic blow molding?
A keyword term for plastic blow molding is "blow molding." The first blow molding machine was created in the 1930s by Enoch Ferngren and William Kopitke.
What was the first machine patented in the US that showed animated pictures or movies?
The first machine patented in the United States that showed animated pictures or movies was a device called the "wheel of life" or "Zoopraxiscope" which was patented in 1867 by William Lincoln .
Injection Molding: Plastic Made Easier?
An injection molding is a scientific process of creating plastic materials through a machine that is convenient and widely used around the world. The first machine was invented in 1872 by John Wesley Hyatt. The machine and the process helps produce materials faster, cuts labor cost, use more materials and has few production loss. Molds are made out of hardened metal or elements and is used to press designs. It is made out of two types of machine, standard machine and electrical discharge machine. For example, plastics are very easy to process, have high chemical resistance, low thermal and low electrical conductivity and are reusable; they are great material for molding. There is a great deal of physics, science and mathematics behind the whole concept of injection and molding methods. First the process starts with filling a mold with resins, such as polypropylene or polyethylene, with colorant into the machine. When the resins fall into barrels it is heated and becomes liquid through a melting point. Then this heated substance which becomes solid and this mold is injected into another device to produce the material. We use products such as bottle caps, combs, Ziploc bags, dashboards which are created by this method on daily base. The injection molding process revolutionized the plastics industry. It is estimated that this process produces about 32% by weight of all the world's plastics. One of the best source to learn more on the precise calculation and scientific methods of the process of molding, authors Gerd Potsch and Walter Michaeli, have a book “Injection Molding: An Introduction” written in detail about the topic. There have been numerous changes in the studies about this process over the years. There are hundreds of published articles and scientific findings on the improvements, advantages and disadvantages about the molding process as well.
How do you estimate the capacity of plastic injection machine?
The injection machine capacity depends on both mould and product. first you need to know what product you want to produce. For the same injection machine, if the product is different, the injection machine capacity is different.

Who invented the mowing machine?
The first mowing machine was a scythe, but, in 1830 Edwin Budding an Engishman patented the first cylinder lawnmower.
