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

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
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.

Aluminum sand casting

Aluminum sand casting Description:

Aluminum Sand casting, the most widely used casting process, utilizes expendable sand molds to form complex metal parts that can be made of nearly any alloy. Because the sand mold must be destroyed in order to remove the part, called the casting, sand casting typically has a low production rate. The sand casting process involves the use of a furnace, metal, pattern, and sand mold. The metal is melted in the furnace and then ladled and poured into the cavity of the sand mold, which is formed by the pattern. The sand mold separates along a parting line and the solidified casting can be removed. The steps in this process are described in greater detail in the next section.

Shell Moulding produces castings with close dimensional tolerances, good surface finish and excellent reproduction of detail. The process often reduces the amount of subsequent machining, assembly, and finishing when compared to conventional moulding.

Die Casting Technology

What is die casting?

Die casting is a casting liquid die forging method. Die casting die forging process is a kind of special casting forging machine to accomplish the process. Its basic technological process is: first metal liquid in low or high-speed casting filling into the mold cavity, die with a moveable type cavity surface, it with the liquid metal cooling process pressure forging blank, both the elimination of shrinkage defects, also make the rough internal Aluminum Die Casting organization to forge the broken crystal. Rough comprehensive mechanical properties are improved significantly.

Aluminum die casting is a method of using high pressure forced the molten metal into complex shapes of hydraulic die within a precision casting method. In 1964, Japan Die Casting Association for die casting is defined as” in the high temperature melting alloy pressing precision molds, in a short time a large number of production of high precision and excellent casting surface”.

The United States said casting for Aluminum die Casting, the UK Pressure Die Casting is called die casting, and the most common domestic industry are familiar with is the Japanese version, called die casting. Through the method of die casting produced in the casting, is called die casting ( Die-castings ).

This material tensile strength, compared to ordinary casting alloy high nearly doubled, for aluminum alloy automobile wheels, frame and hope to use more high strength and impact resistant material production parts, have more positive significance.

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

Power solar “wings” using new technology

For manned space flight, the aircraft power subsystem has always been the lifeline.

This time, Temple One pressure on the semi-rigid solar wing, the technology of China’s first spacecraft power subsystem applications. Externally, two solar wings like a pair of “wings” covered with horizontal black solar film, artful. The face of low-orbit space station environment, before the full use of high-orbiting satellites are obviously not applicable to rigid panels. After a number of technology experiments, researchers identified the Shanghai grid panels with fiberglass glue and glue concentration in the actual operation and other parameters to determine the carbon-fiber frame with glass fiber mesh of semi-rigid structure.

The characteristic of die casting

High Pressure die casting or gravity casting, is a molten gold poured into the pressure chamber, to the high speed filling steel mold cavity, and the alloy liquid under pressure solidification and casting method. Die casting is distinguished from other casting method is mainly characterized by the high pressure and high speed. The metal liquid is under pressure to fill the cavity, and at higher pressure solidification under common pressure, 15 to 100MPa. The liquid metal to the high speed filling cavity, usually in the 10 – 50 meters / second, some still can exceed 80 m / s, ( through the gate into the cavity of the line speed gate speed ), thus the filling time is very short, about 0.01 – 0.2 seconds ( must be considered casting size different ) can fill the cavity. Die casting machine, die casting alloy and die casting is a casting production of the three elements, are indispensable.

die casting process is called the three major elements of organic ground be used, enabling stable rhythmically and efficient production of appearance, inherent quality good, size consistent with patterns or the agreement in accordance with the requirements of qualified casting, even high-quality casting. Die casting is a kind of precision casting method, through casting and metal die-casting dimension tolerance is very small, the surface accuracy is very high, in most cases, die castings without further machining to assembly application, threaded parts can also be directly cast.

From the general photography, typing machine, mechanical computing devices and accessories and other small parts, as well as the automobile, locomotive, aircraft and other means of transport complex parts using mostly die casting manufacturing.

Die casting method also has the following shortcomings:

( 1) Die Casting Alloy is restricted at present only zinc, tin, lead, copper, magnesium, aluminum and other six kinds of copper alloy, with the highest melting point. Recently there have been reports of cast iron casting, but for the sake of economic factor, must be related to the research of materials, mold materials and operation method.  
( 2 ) expensive facilities needed equipment such as the production of the die casting machine, melting furnace, holding furnace and casting mold costs are quite expensive. 
( 3) the casting of poor airtightness due to melting liquid by high-speed filling to die when, can produce turbulence phenomenon, the local formation of a stoma or shrinkage, influence the airtightness of castings. There is currently an IMPREGNATION processing method, can be used to improve the resistance to airtightness.

Materials

Acetals: Delrin® – Celcon®
Acetals are available as a homopolymer (Delrin by Du Pont) or a co-polymer (Celcon by Celanese). Both materials offer excellent machining properties and are ideal for holding close tolerances. The high compression strength and stiffness of acetal make it a good material for high-load applications. Acetal is also available with additives such as moly dry lubricants and Teflon® fibers. These reduce friction and aid machinability.

Nylons
Nylon is available in several compounds and co-polymers. The most commonly used nylons for industrial components are Type 6 (cast) and Type 6/6 (extruded). Both materials exhibit excellent wear resistance and tensile strength, with Type 6 offering slightly better mechanical properties. Nylon generally absorbs more moisture than other bearing materials and therefore may be dimensionally unstable in wet applications requiring close tolerances. Nylon is available in oil or molybdenum disulphide filled compounds which offer a lower coefficient of friction for bearings and wear parts.

PTFE: Teflon®
Polytetrafluoroethylene (PTFE) provides exceptional chemical, electrical, mechanical and thermal properties for many applications. The most recognized source of PTFE resin is Teflon manufactured by Du Pont. PTFE is capable of operating at temperatures up to 550ºF, making it a versatile high-temperature material. Glass fibers are often added to improve the dimensional stability of PTFE under load.

UHMW-PE: Duro-Glide®
UItra-high molecular weight polyethylene (UHMW-PE) has the highest impact and abrasion resistance of any thermoplastic. These properties and its reasonable cost make UHMW a versatile material for many applications where abrasion, impact, or chemical resistance is desired. The low coefficient of friction and high-slip properties of UHMW make it ideal as a wear liner for handling bulk commodities. UHMW can operate successfully at temperatures as low as – 375ºF, making it excellent for cryogenic applications.

Duro Lube
Oil-filled UHMW polyethylene is ideally suited for applications such as wear strips, slider plates and some bearing surfaces where lubrication is desirable to lower the coefficient of friction. All additives in Duro-Glide (white) and Duro-Lube meet FDA requirements for direct food contact.

A major advantage of rotamoulding is the low tooling cost compare to plastic injection mold, and die casting, is you are looking for China Plastic Mold Company, you can contact us.

Since the heating and fusing of resin inside a slowly rotating closed mould does not require high pressure, moulds, therefore, need not be as costly or complex as those tooled for other processes. Depending on requirements, moulds can be made from several materials:

Cast aluminium alloy: the popular choice, with good heat transfer and excellent mould definition. It is best for small to medium sized mouldings.

Sheet mild steel: for fabricating moulds for large mouldings.

Cast beryllium copper: for quality moulds producing very detailed surface finishes.

Electroformed copper nickel: suitable for undercuts and the highest surface reproduction and finish.

90% of rotational mouldings are made of polyethylene (PE), a polymer with immense versatility ranging from food grade to vandal-resistant and flame retardant grades for handling waste materials, fuels and corrosive substances.

Cross-linkable PE has been developed with superior resistance to chemicals and environmental stress cracking suitable for the production of canoes, chemical plant and high performance containers.

In addition to polyvinyl chloride, EVA, polyester elastomers and certain rubbers for moulding flexible and inflatable products, engineering polymers have also been developed including polypropylene, nylon, polycarbonate, and polyurethane.

Some thermosets have been introduced too. However, the flow characteristics of the resin are all important for successful processing, hence the ubiquity of polyethylene. if plastic molding parts made in polyethylene, it is PP injection molding, need this service? Contact us.

These materials and technological advances, combined with well designed surface finishes and graphics, are leading to the rotamoulding process away from traditional solutions into new areas of product application.
