Die Casting Design

Die-casting can be done using a cold chamber or hot chamber process.

1. In a cold chamber process, the molten metal is ladled into the cold chamber for each shot. There is less time exposure of the melt to the plunger walls or the plunger. This is particularly useful for metals such as Aluminum, and Copper (and its alloys) that alloy easily with Iron at the higher temperatures.

2. In a hot chamber process, the pressure chamber is connected to the die cavity is immersed permanently in the molten metal. The inlet port of the pressurizing cylinder is uncovered as the plunger moves to the open (unpressurized) position. This allows a new charge of molten metal to fill the cavity and thus can fill the cavity faster than the cold chamber process. The hot chamber process is used for metals of low melting point and high fluidity such as tin, zinc, and lead that tend not to alloy easily with steel at their melt temperatures. die casting, aluminum die casting, aluminum casting, ADC-12 die casting, automotive die casting part, motorcycles spare part, aluminum pressure die casting

3. Die casting molds (called dies in the industry) tend to be expensive as they are made from hardened steel-also the cycle time for building these tend to belong. Also, the stronger and harder metals such as iron and steel cannot be die-cast

Aluminum die casting process introduction

Though the term die casting can refer to any kind of casting using a die such as gravity die casting or low pressure die casting, yet here die casting only refer to high pressure die casting. Aluminum die casting is a process of casting Aluminum alloy under pressure, can produce precision parts in high volume at low costs. There are two processes of aluminum die-casting namely hot chamber die casting and cold chamber die casting. Parison die casting introduced cold chamber die casting process from1980’s. Now the die casting machines which Parison die casting is applying are cold chamber die casting machines.

Illustration of cold chamber die casting process

In a cold chamber die casting process, the molten aluminum alloy is ladled into the cold chamber for each shot. There is less time exposure of the melted alloy to the plunger walls or the plunger. This is particularly useful for aluminum alloy that alloys easily with Iron at the higher temperatures.

After the molten aluminum alloy is ladled into the cold chamber, the piston will inject it into the cavity of the die casting mold through three different pressure phrases. The pressured molten aluminum alloy gets in sequence through spure system, running system, and gate system into the cavity of the die casting mold.

The filled cavity with affection of cooling system shapes the desired aluminum die casting products. Then the moving die moves away from the fix die, while the ejectors push out the casting.

Advantage of aluminum die casting process

A.high volume but low cost Compared with aluminum sand casting and gravity casting, aluminum die casting can produce precision parts in high volume at low costs.

B.good surface finish and good dimensional accuracy Aluminum die casting generally has good surface finish and good dimensional accuracy. For many parts, post-machining can be totally eliminated, or very light machining may be required to bring dimensions to size.

The disadvantage of aluminum die casting process

A.high cost of die casting mold The cost of tooling of die casting is much more expensive than those of sand casting, gravity casting, and investment casting.

B.high porosity Though the porosity of die casting can be adjusted by using much higher pressure with a much larger and heavier mold, the porosity can not be avoided and is much more than that is of low-pressure casting and gravity casting. Furthermore, porosity leads die casting parts to be not suitable for heat treatment. Thus the consistency can not be compared with gravity castings.

Alloy Die Casting

Alloy Die Casting Description:

Aluminum Alloy Die Casting A380 is the most common of the aluminum die casting alloys. It offers the best combination of casting and product properties. It is used for a wide variety of products such as garden equipment, chassis for electronic equipment, engine brackets, housings for automotive alternators, starters and water pumps, home appliances, furniture, office equipment hand tools, and power tools. Alloys 383 and 384 are alternatives to 380 that are specified when very intricate components require improved die filling characteristics and improved resistance to hot cracking. Alloy 360 offers high corrosion resistance and superior strength at elevated temperatures than 380. Other properties are essentially equivalent. Alloy 413 offers the best die fill characteristics making it excellent for pressure tightness applications. it is the choice for products such as hydraulic cylinders and pressure vessels. Its casting characteristics make it useful for very intricate components.

Alloy 390 was developed for automotive engine blocks. Resistance to wear is excellent, but ductility is the lowest of the die casting alloys, with elongation less than 1%. Special surface treatment systems allow engine pistons to run directly on the alloy surface, eliminating the need for ferrous alloy liners. It can also be used for valve bodies and bearing surfaces subject to abrasion and wear.

Alloy 518 is used in escalator components, conveyor components, and marine and aircraft applications It offers good ductility and very good corrosion resistance. It can be polished and anodized for a decorative finish. Zinc Alloy Die Casting Zinc alloys are versatile, cost-effective materials which can be used in a diverse range of die casting applications. As precisely formulated metal alloys, they offer the mechanical properties of medium strength metals. Advantages of Zinc Alloy Die Casting Overall, zinc alloys have significant advantages as casting materials for small components, with excellent physical and mechanical properties, castability and finishing characteristics. Hot chamber die-cast zinc alloys can be cast to tight tolerances, complex detail, net shape, and the alloy¡¯s dimensional stability ensure part-to-part consistency over long production runs. Net shape manufacturing is one of the main advantages of hot chamber die-cast zinc alloys.

The most commonly used zinc alloys are ZAMAK™ 2, ZAMAK™ 3, ZAMAK™ 5, Acuzinc. These alloy families offer higher tensile strengths than most aluminum and magnesium alloys, higher yield strengths, greater impact resistance, higher Brinell hardness, and better ductility. ¡¡è Zinc alloys facilitate higher die casting cycle speeds versus aluminum and other metal alloys, more complex shapes, thinner sections, smoother surface finishes, surface finishes, and higher standards of dimensional accuracy. Compared to plastic, zinc alloys are several times stronger and many times more rigid. Their mechanical properties compare favorably with powdered iron, brass, and screw-machined steel. Zinc has inherent EMI/RFI shielding properties.

CNMCast uses only high-grade zinc alloys certified for purity. Although these materials are completely recyclable, scrap is never re-melted or re-used within our process. Zamak 3 die casting is the standard for the Zamak series of zinc alloys; all other zinc alloys are compared to this. Zamak 3 has the base composition for the Zamak alloys (96% zinc, 4% aluminum). It has excellent castability and long term dimensional stability. More than 70% of all North American zinc die castings are made from Zamak 3. ZAMAK #5 offers high tensile strength, hardness, and creep resistance than zamak# 3, and somewhat lower ductility.

It is preferred whenever these properties are required. Some die casters use only zamak# 5, which is usually an acceptable alternative to zamak# 3. ZAMAK #7 is essentially a high purity form of zamak# 3 with slightly higher ductility and lower hardness. The other mechanical properties are identical to zamak# 3.

The alloy also exhibits higher fluidity than zamak# 3 or3 5, which theoretically allows slightly thinner walls. Zamak# 7 may be specified when high ductility is required. ZA-8 is rapidly growing in popularity for pressure die casting.

ZA-8 can be cast in hot chamber die casting machines for fast cycle rates, It has improved strength, hardness and creeps properties over the ZAMAK alloys with the exception of a No. 2 alloy which is very similar in performance. ZA-8 is readily plated and finished using standard procedures for ZAMAK. When the performance of Zamak No. 3 or No. 5 is in question, ZA-8 is often the die casting choice because of high strength and creep properties and efficient hot chamber castability.

Zamak 5 die casting

ZA-12 is also a good pressure die casting alloy, using the cold chamber process, which provides a sounder structure than ZA-27, as well as higher die-cast elongation and impact properties. For these reasons, die-cast ZA-12 often competes with ZA-27 for strength application. An excellent bearing alloy, ZA-12 is also platable, although plating adhesion is reduced compared to the ZAMAK alloys. ZA-27 is the high strength performer of the zinc alloys and is die-cast using the cold chamber process.

It is also the lightest alloy and offers excellent bearing and wear resistance properties. ZA-27, however, requires care during melting and casting to assure sound internal structure, particularly for heavy wall sections. It may also need stabilization heat treatment when tight dimensional tolerances are required. ZA-27 is not recommended for plating. However, when brute strength or wear-resistant properties are needed, ZA-27 has demonstrated extraordinary performance.

New material of aluminum-lithium alloy

Yesterday, reporter learned from Shanghai Academy of Spaceflight Technology, the hospital in Temple One goal of the task assumed aircraft cabin structure and assembly of resources, power sub-systems, docking mechanism subsystem, control and communication subsystems supporting stand-alone subsystems and overall circuit Resource module cable network research task.

Resource tank “fuel” an increase in total weight was reduced by 10%

Temple One of the energy as a source of resources and power module, and the JEM to be connected with the launch vehicle, in addition to ensuring a reliable connection, the cabin is also equipped with a number of subsystems within and outside the nearly 200 sets of equipment and a large pipe, cable and so on. The structure of the resource module design, installation and testing have brought a lot of problems. Development process with a large number of new technologies, new processes.

Designed from the start, the resource module is facing, “weight” problem. Because the resources to carry propellant tank before the Shenzhou spacecraft than an increase of 50% or more, but the construction of the main cabin still hope for the implementation of weight loss. In this way, before the use of aluminum is difficult to meet the requirements, the first use of aluminum-lithium alloy as the raw material, 10% of successful weight loss for the cabin.

In order to maintain long-term in-orbit requirements of the target aircraft, the entire device carried by the lofty air and oxygen-carrying capacity of a single spacecraft, for environmental control and life support sub-system uses a large-capacity high-pressure composite cylinder for gas storage. It is reported that the inflatable cylinders before and after the change in the direction of larger diameter, the resource module assembly with a certain flexibility in design of cylinders installed bands, difficult to install to solve the problem of the cylinder, greatly reducing the weight of the cylinder mounting bracket for the entire device contributed to weight loss. Aluminum Casting Heat sink parts

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.

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.
