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-plank/ ). It is only now that we are becoming aware that the original inventor of injection molding was Fritz Schmedke who patented his method shortly after similar efforts by other individuals elsewhere.

As a leading manufacturer of injection molding machines, we specialize in manufacturing, designing and exporting a wide range of the products to meet customers' requirements. Our company has been committed to the development and production of injection molding machines for more than 50 years, with excellent quality control system. Our products are widely used in various industries such as electrical appliances and toys

Engel injection molding machine history. Engel injection molding machine is a production equipment for plastic and rubber molds, it has been used in the fields of medicine, electric appliances, plastic packaging, toys and other fields of industry and engineering.

In 1949, Yale and his research team began working on the development of a new type of plastic machine. The design was patented in 1954. A year later, in 1955, the first Engel injection molding machine was given to John McKean, president of Chicago based plastic machinery corporation Case International Corporation.  In 1956 Case bought out Engel's patent and started production under their own name.
