Die Casting Offer Rapid Tooling

GC Die Casting Offer Rapid Tooling

Cleveland, OH – Advancements in rapid machining and prototyping are being developed at Case Western Reserve University (CWRU) that will considerably shorten the lead time for die casting tooling. Rapid tooling is important when a relatively small number of parts are required. This is important to DLA when tooling is no longer available to produce spare parts for aging weapon systems. Tooling lead time can play critical role to the overall procurement lead time, significantly affecting weapon system readiness. Rapid tooling methods that shorten lead times and reduce costs will expand the DLA casting supply base for high quality, dimensionally accurate parts.

Over the past year, CWRU has been working with NADCA and GC Die Casting company to develop a higher quality heat sink for military-tracked vehicles utilizing rapid tooling methods. Rubberized tank tracks are subjected to demanding operating conditions. In addition to normal wear and tear, they are exposed to temperature extremes that can affect performance and result in separation between the rubber and the track. To prevent separation, an aluminum heat sink that absorbs excessive heat from the rubber is embedded between the track and the rubber. Die casting is the most cost effective fabrication method for this heat sink because of the large production volumes involved.

GC Die Casting company, the die caster for these parts, had to frequently replace the HI3 steel dies because of excessive thermal fatigue cracking. The project team recommended replacing the HI3 steel dies with two alternate grades of steel. The new dies were completed in record time utilizing rapid tooling methods. Compared to HI3, a die set fabricated from one of the alternate steel grades produced twice as many castings before any welding repair was deemed necessary. The die set fabricated from the other alternate steel grade made three to four times as many castings. NADCA and AFS are supporting the technology transfer to their membership and CWRU is applying the lessons learned on Rapid Tooling to recent USCAR and DOE projects. In the the coming year, CWRU will collect, process, and report performance data from the rapid tooling production guidelines for fabrication of rapid tooling. The close collaboration and synergy fostered by the AMC program between the R&D teams, the CAST-IT application engineers, and the metalcasting associations and their members is very unique, making significant contributions to DLA and the metalcasting industry.

China Die Casting Process

China Die Casting Process

Aluminum Die Casting is a 6000 year old manufacturing process. Aluminum die Casting is a manufacturing process by which a liquid material is usually poured into a die mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process. Casting is most often used for making complex shapes that would be otherwise difficult or uneconomical to make by other methods. Die Casting China was grow up since 1960, and rapidly grown up in recently 20 years.

Die Castings are used in areas like transportation, aerospace, defense, mining, construction, maritime, fluid power, & domestic household. Some cast components include: engine blocks, suspension parts for  auto mobiles, cooling fan components & fluid flow components like valves, pumps, pipes, and fittings. To cut the emissions there is a need to improve the fuel efficiency and make the vehicle lighter in weight. Non ferrous metal like aluminium is lighter than steel and has density one third of that of steel. Aluminium has a lower density of 2.7 gm/cc compared to 7.8 gm/cc of steel. Aluminum and aluminum alloys are lightweight with good corrosion resistance, ductility and strength. Aluminium is a light silver coloured metal placed 13 on the periodic table and is important group 3 element. It has good resistance to corrosion and due to its aesthetics it makes a suitable alloy for varied applications.
 Dr. Dinesh & Ramesh is in the process of manufacturing Aluminium die casting of various alloys including LM6, LM9, LM25, A356, 413, AlSi8Mg3, AlSi10Mg amongst others. There are various casting processes including Gravity Die Casting (Permanent Mold Casting), Low Pressure Die Casting, High Pressure Die Casting, Investment Casting, Sand Casting processes. Dr. Dinesh & Ramesh have expertise in the Gravity Die Casting and Low Pressure Die Casting processes since 1979.
In Gravity Die Casting process the metal is filled under the influence of gravity hence the name Gravity Die Casting.  The metal is carefully directed through an ingate under the influence of gravity to fill the die. There are various gates and sprues through which Aluminium enters the dies (usually made of iron alloys).There is provision of various risers to allow proper feeding and give defect free homogenous casting. It is the experience and knowledge of the foundry engineer to provide optimum risering and gating to give defect free parts. Dr. Dinesh & Ramesh has that experience and knowledge of more than 30 years to give customers value and quality. At DRE, we have always been up to speed with technology and have developed various equipments at our facility to increase productivity and sustained quality of our products to our customers.
Die Casting China Companies has also developed its own proprietary equipment for Low Pressure Die Casting. This is a relatively newer process in which metal enters into a die in a very controlled and turbulence free manner. An air tight furnace is kept underneath the metallic mold, and under air pressure (upto 25 psi – depending on the size of the casting) the liquid metal rises up from the furnace into the metallic die on top of the furnace. A very good control of the molten metal is achieved in this process resulting in reliable, pressure tight and homogenous parts. Various critical components in the industry are made through this process for eg: Engine blocks of automobiles, cyclinder heads, alloy wheels, crticial electrical components, special purpose pressure tight parts to name a few.

Mechanical Properties of Malleable Iron

The different grades of malleable iron are essentially the result of different heat treatments. Just as a medium carbon steel can be heat treated to a wide range in properties so can malleable iron, but malleable is even more versatile. The combined carbon content, on which heat treatment depends, can be adjusted from none, as when the microstructure is entirely ferritic, to that of a fully pearlitic structure. Read more

Mechanical Properties of Cast Carbon and Low Alloy Steels

For the purpose of this article, carbon steels are considered to be those steels in which carbon is the principal alloying element. Other elements that are present and that, in general, are required to be reported are manganese, silicon, phosphorous and sulfur. In a sense, all of these elements are residuals from the raw materials used in the manufacture of the steel, although the addition of manganese is often made during the steel making process to counter the deleterious effect of sulfur and silicon is added to aid in deoxidation.

White and High Alloy Irons

An important group of alloyed irons that fall outside of the ordinary types of Alloy Die castings have been designated the white and high alloy irons, or the special irons. The high alloy irons are considered separately because their alloy content exceeds 3% and they cannot be produced by ladle additions to irons of otherwise standard compositions.

The high alloy irons are usually produced in foundries that are specially equipped to produce the highly alloyed compositions. These irons are often melted in electric arc or induction furnaces, which provide for precise control of composition and temperature. The high alloy irons are sold at premium prices and are expected to outperform ordinary compositions in applications that involve severe service conditions. The foundries that produce these irons may be equipped with heat treating furnaces and quenching equipment or cooling facilities to provide for the most economical use of alloys. Read more

Cast Copper Alloys

A Primer on Selecting Cast Copper Alloys

Traditionally, cast copper alloys were classified by a variety of systems including the ASTM letter-number designation based on nominal composition, by trade names, and by descriptive terms such as “ounce metal,” “Navy M” and so forth. However, with technological developments, new alloys were produced and existing alloys modified, making the old designation systems inadequate and misleading.

A new system was developed based on a precise description of the composition range for each alloy, which is now the accepted alloy designation system used in North America for cast copper and copper alloy products. Originally developed as a three digit system by the copper and brass industry, the designations have now been expanded to five digits that follow a prefix letter “C,” and have been made part of the Unified Numbering System (UNS) for Metals and Alloys. The UNS is managed jointly by the American Society for Testing and Materials, and the Society of Automotive Engineers. Read more

Aluminium Casting

A Basic Guide to Choosing Aluminum Casting Alloys Part 2

Alloys 319.0, A319.0, B319.0 & 320.0
Alloys 319.0 and A319.0 exhibit very good castability, weldability, pressure tightness and moderate strength. They are very stable alloys (i.e., their good casting and mechanical properties are not affected seriously by fluctuations in the impurity content). Alloys B319.0 and 320.0 show higher strength and hardness than 319.0 and A319.0 and are generally used with the permanent mold casting process. Characteristics other than strength and hardness are similar to those of 319.0 and A319.0. Read more

Aluminum Casting Alloys

The mechanical properties of alumi- num casting alloys are obtainable only if the chemical and heat treating specifications are followed carefully. It should be noted that the properties obtained from one particular combination of casting alloy, foundry practice and thermal treatment may not necessarily be identical to those achieved with the same alloy in a different foundry or with a different thermal treating source. In all aluminum casting alloys, the percentages of alloying elements and impurities must be controlled carefully. If they are not, characteristics such as soundness, machinability, corrosion resistance and conductivity are affected adversely. Read more
