The Injection Molding Machines

The Morgan-Presses are versatile injection molding machines designed to reduce the costs of production.  Its unique design was especially developed to make injection molding of plastic molded parts practical and economical in the quantities required for rapid prototyping and low-volume production.  This makes it ideal for model shops,medical device manufacturers, R & D labs, and many other plastic injection molding applications that require short-run production needs.

Features on all Morgan’s injection molding machines:

  • Solid State Temperature Controllers – featuring digital set-point and readout, 3-mode proportioning and programmable controls, 0-800°F/0-430°C 1/8 DIN modular units.
  • Injection Speed Control – for adjusting injection speeds slower and faster where cavity fill rates are critical
  • Heavy duty cast aluminum construction
  • Hardened and chrome-plated barrels (material melt cylinders)
  • Precision ground chrome-plated stanchion rods
  • Generous 8″x11″ (maximum) mold plan area

Theory of injection molding


The theory of injection molding can be reduced to four simple individual steps: Plasticizing, Injection, Chilling, and Ejection. Each of those steps is distinct from the others and correct control of each is essential to the success of the total process.

Plasticizing – describes the conversion of the polymer material from its normal hard granular form at room temperatures, to the liquid consistency necessary for injection at its correct melt temperature.
Injection – is the stage during which this melt is introduced into a mold to completely fill a cavity or cavities.
Chilling – is the action of removing heat from the melt to convert it from a liquid consistency back to its original rigid state. As the material cools, it also shrinks.
Ejection – is the removal of the cooled, molded part from the mold cavity and from any cores or inserts.
Repetition of these basic steps in sequence is the process of injection molding.

The practice of injection molding
The practice of injection molding varies from the theory, only in as much as process limitations and available equipment affect it. Step by step process is explained in ST’s Cutting Costs in Short-run Plastic Injection Molding guide.

High-Performance Inspection Probe

High-Performance Inspection Probe
Introduced for Machining Centers

Renishaw Inc.‘s new OMP40 probe is a significant development that brings the benefits of automated part set-up and in-cycle gaging to small machining centers and high-speed cutting machines. With the OMP40, you can realize the benefits of probing, including reductions in set-up times of up to 90%, reduced scrap due to setting errors, reduced fixture costs, and improved process control.

The OMP40 uses miniaturized electronics that allow an ultra-compact probe that is 40 mm (diameter) by 50 mm (length), while still delivering a metrology performance of 1µm repeatability.

The OMP40 operates with Renishaw’s optical signal transmission system and is a further development in the company’s extensive range of products for machining centers. It was designed to meet a demand for probing on small machining centers and an expanding family of high-speed machines fitted with small HSK and small-taper spindles.

The OMP40 features a 360° optical transmission system with a range of up to 3 m, allowing probe operation in any spindle orientation. The result is simplified system installation and set-up on small machine tools, making the OMP40 suitable for retrofitting to machines without probing.

 

Latest Version of Handbook on
Machine Tool Resources Now Available

The latest version of a valuable resource on the world machine tool industry is now available from The Association for Manufacturing Technology. The 2002-2003 Economic Handbook of the Machine Tool Industry offers the latest information on the US and global machine tool industries. It covers employment, machine tool shipments, machine tools in use, and the financial condition of the industry by location.

The handbook contains approximately 300 pages including written overviews and an explanation of terms. Both product-specific and country-specific data are included. Information on capital equipment purchases is broken out for several major consuming industries.

 

AMBA Creates New Chapter for
Northern Ohio; 22 Firms Sign On

One of the more extensive association for the mold industry and one dedicated to mold makers is the American Mold Builders Association which has announced the organization of its 12th chapter, the Northern Ohio Chapter. In a summer meeting, 36 individuals from 22 companies throughout Ohio agreed to the formation of an official chapter. Dave Hunt, vice president of Hunt Machine & Manufacturing Co. in Tallmadge, Ohio, will serve as chapter president. Hunt is the third generation of his family to operate the 50-year-old mold making business. Assisting Hunt on the steering committee to select officers and committee members are Tom Nahodil and Dave Kuhary of Industrial Mold & Machine in Twinsburg, Ohio.

AMBA has grown from its original roots as a Chicago-based group to a national trade association with over 400 member companies with 9,000 employees and representing in excess of $2 billion in annual tooling sales. AMBA has chapters in Arizona, the Carolinas, California, Chicago, Milwaukee, Indiana, Minnesota, Upstate New York, and three chapters in Michigan.

With plastic injection molding, many parts might be made simultaneously (using the same mold). Plastic injection molding companies apply various different molding techniques to produce plastic components. These strategies incorporate thermoplastic and thermosetting injection molding, transferring to resin, blow molding, gyratory molding, compression molding, thermoforming, structural foam molding and many others.

Plastic injection molding is an extremely technological process. It requires experts in this kind of manufacturing business it to be competitive to the market. Consequently, a very scientific and systematic study must be first made before starting this opportunity. If you are planning to go directly into plastic injection molding business, you need to first know the different processes. Choose from a plastic injection molding process that matches your budget, your expertise, and your resources. Some plastic injection molding manufactures take your current strategy from primary prototype by means of production, delivery and finishing.

They’ve got an experienced staff of experienced engineers, designers and toolmakers who work with clients from building the concept to making the prototype also to the manufacturing from the precise custom mold. Serious trading mistakes sophisticated computer system assisted design and technology and also the latest equipment, they might produce clients with a technically exceptional mold and assure every product’s success.

It’s recommended to decide on vendors that are quickly, flexible and customer-driven, especially if you would like great amounts and quick transformation or specific little volume operates. Choose plastic injection molding companies which may have state-of-the-art injection molding amenities and machines that differ within weight from 75 to 500 tons.

See if they have full scale thermoplastic and thermosetting capabilities with computer aided manufacturing, skilled machine operators and first class level of quality assurance team. This guarantees that their output experiences high-quality plastic injection molding, which it appears the test of time.
