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.

Plastic Molding Company

Plastic Molding Company

Plastic molding is a popular method that is used when manufacturing toys, injections, and other plastic products. In fact, many of the plastic products that we use on a daily basis (like our cellphones) are manufactured by a process called preform molding. in that case if you need and type of custom plastic molding parts then you need plastic mold maker and plastic molding company to support your business.DONGGUAN SINERE TECH CO.LTD will be the best option for you.

In the year 1872, the injection molding machine was introduced; the process that it uses later became knowns as blow molding. This technology proved to be essential in the manufacturing of plastic bottles, and in recent years, the molding industry has seen rapid growth due to a number of technological advancements. Now there are a number of different types of molding machines available to help companies manufacture plastic cap molds, bottle cap molds, bottle closure molds, and more.

Most of the plastic products that preform molding customer uses today have complex shapes. Therefore, to get the optimal shape for their products, they must utilize the services of an innovative and technologically advanced preform molding manufacturer. Using advanced technology enables the manufacturer to provide their clientele attractive shapes for their various products.

The manufacturers who use modern technology for their plastic molds cause less environmental damage; for example, the preform bottle Cap Mold can be reused and recycled. An added benefit to this eco-friendly practice is the reduction of costs, in this way they are able to charge less money for their plastic molds.

When individuals are looking for the best preform mold manufacturers for their plastic products, it is important to look for certain traits. For example, it is essential to give credit to the mold manufacturers who spend a lot of time, resources, and who use the latest technology in order to design and purchase the tools that they need. If that manufacturer is able to provide its clientele with budget-friendly methods and technical expertise, then it is wise to invest your resources in their product.

Another consideration when choosing the perfect preform molding supplier for your needs is experience. If a company has been manufacturing plastic bottle molds or bottle cap molds for over five years, then you can be sure that it is a trusted company and that it is safe to do business with them. A good way to get your hands on this type of information is to check out client reviews and testimonials. In addition, most reputable plastic mold manufacturers tend to provide high quality products at a suitable price. So, before choosing your supplier, check out some of their products to see if it is worth your investment.

Thermoset Compression Molding

Thermoset Compression Molding

Thermoset compression molding is historically the most common method of molding thermosetting resins; it is certainly the oldest, and many existing molds are of this type. Compression molds typically have a single cavity, although dual-cavity and even multi-cavity molds are possible.

A preheated preform is placed in the open mold

As the mold closes, the preform is compressed and starts to flow

The heated mold is held shut until the resin cures …

… then the mold is opened and the finished part ejected.

What characterizes compression molding is the method of charging the mold with resin: the plastic resin is placed directly in the bottom cavity of the open, heated mold, and then the top half of the mold is closed down on the resin under tremendous pressure, causing the resin to flow throughout the cavity until it completely fills the now-closed mold and assumes the shape of the finished part.

COMPRESSION MOLDING WORKS

The compression action itself generates heat, and in conjunction with the heat of the plastic mold, raises the temperature of the resin to the point where a chemical reaction called “crosslinking” takes place. It is this crosslinking that gives thermoset molded parts their characteristic strength, hardness and rigidity.

The heated mold is held closed for sufficient time to ensure that the crosslinking reaction is complete; this is called “curing,” and the length of time required for the cure cycle is almost entirely dependent on the wall thickness of the finished part. The thicker the part at its maximum cross section, the longer the curing time required for a given mold temperature.

Thermoset molding resins typically come in a powder or granulated form. Metering the correct amount of resin (called the “shot”) into the mold is accomplished in one of two ways. One is called “preforming” and the other is called “direct charging.”

PREFORMING
In preforming, the exact amount of raw resin required to completely fill the mold (plus a small excess percentage to allow for squeeze-out) is compressed into uniform “pills” — sometimes called “hockey pucks” in industry slang, because that’s what the larger ones look like. These preformed “pills” of resin are produced in batches prior to molding using machines called, appropriately enough, preformers. Preforms are made in various sizes, depending on the size of the mold.

PREHEATING
Just before use, these preformed pills are warmed up in a preheater — which is essentially an industrial-strength microwave oven — which softens the pill into a pliable, dough-like consistency so that the resin will flow more easily under compression. In the molding process, one of these preformed, preheated pills of resin is placed in the bottom cavity of the mold, and the mold is closed, compressing the softened resin into the shape of the mold. (Exceptions to preheating include Bulk Molding Compound (BMC) materials, which are typically formed in logs or used in bulk and are normally molded cold.)

DIRECT CHARGING
Direct charging is used in situations where the mold cavity is too small, too shallow, or too convoluted, to conveniently accept a preform. In these cases, a measured scoop of cold resin is distributed directly into the open mold cavity.

INSERTS
Metal inserts — electrical contacts, female threaded holes, male threaded studs, bushings, and the like — can be placed in the mold cavities, using holes or locator pins, prior to molding. Under compression, the plastic resin flows around these inserts, molding them into the finished piece. Even though thermoset plastics are machinable to a degree, the judicious use of molded-in metal inserts can often eliminate costly secondary operations and add value to the finished parts.

Metal inserts can be molded into the bottom surface, the top surface, or both surfaces of the finished parts. They can even extend completely through the piece. In cases where the inserts are especially small, or cannot be properly supported within the mold, they can be epoxied in as a secondary operation.

THERMOSET COMPRESSION MOLDING:
ADVANTAGES and DISADVANTAGES

In general, thermoset compression molding is well suited for larger pieces of relatively simple design with large, well-anchored inserts. A properly designed and well maintained compression mold will produce very little scrap, and through the use of preheated preforms, total cycle times can rival those of injection molding, plastic molding company

On the PLUS side …

  • Less expensive molds. Compression molds are generally less expensive than other types, both in initial cost and in maintenance.
  • Tighter tolerances, made possible by relatively small shrinkage. Because of the way direct compression packs the preheated preform into the mold, the result is a denser piece that tends to cure solid to the exact dimensions of the mold cavity, without “relaxing back” to create shrinkage. (Exception: dimensions across the parting line are harder to control.)
  • Less scrap can lower material costs.
  • Low-volume jobs are more economical, due to the simplier process and reduced start-up times. Compression jobs can be cycled in and out of the workflow more quickly, and on shorter notice.

On the MINUS side …

  • Heavier flash than other methods is possible. Deflashing is a secondary operation that may add to both labor costs and scrap loss.
  • Labor costs vs. cure time trade-offs. Labor costs can be reduced by using BMC materials and other cold molding techniques which forego preheated preforms, but the cure cycles will be longer.
  • Parting line thicknesses can vary making dimensions across the parting line more difficult to control tightly.
  • Metal inserts may be flashed, leading to more labor-intensive deflashing and clean up.
  • Deep, small diameter holes are difficult to mold reliably; in general, cored holes should be limited to 2.5 times their diameter in depth.

Typical Applications

Thermoset compression moldings are all around you. From the knobs on your stove to the electrical boxes in a jumbo jet — if it’s plastic, hard, rigid, heat-scratch-and-chemical-resistant, an electrical insulator, and it’s got molded-in metal inserts, and it’s black (or shades of reddish brown) — chances are it’s a thermoset molded product.

  • Aerospace — an aircraft terminal housing is just one example where thermoset moldings provide the excellent dielectric properties, lightweight rigidity, and dimensional stability required by precision in-flight systems.
  • Household Appliances — a blower fan blade for a residential clothes dryer illustrates the ability of thermoset compression molded products to meet critical density and dimensional stability requirements.
  • Industrial Machinery — an adjustment wheel for an industrial milling machine displays the rugged workhorse qualities of a typical thermoset compression molding.

Other Molding Methods

Compare with Thermoset Transfer Molding, which is similar to compression molding, but with important differences.

Compare also with Thermoset Injection Molding, a familiar process in thermoplastics, now equally applicable to many thermoset materials.

How To Avoid Mould Cracking Issue

How To Avoid Mould Cracking Issue

Crack is which we can see in mould .The crack in the mould will damage the life of the mould.

(1)  Unreasonable Structure design lead to crack and how to avoid

In the design of plastic mould structure, unreasonable structure design, for example, bolt hole is too closer to the edge will decrease the strength; the corner is not smooth , causing stress concentration, all these reasons will lead to mould crack  during molding process. For this structural cracks, because the mould has already done, it is not possible to change structure, we can only add frame to strength it. plastic mould

(2)  unreasonable heat treatment result in cracking in mould and how to avoid

There are many  parts in mould, such as cavity and core, guide bush, guide pillar, all these need heat treatment, to improve the abrasive resistance and prolong the mould life. But if we choose unreasonable heat treatment condition, makes big difference between spare parts material. This difference will lead to crack. For this, we should pay more attention to the heat treatment condition, controlling the heat operating strictly

(3)  The less stiffness of mould and how to avoid

Injection mould wills under big pressure when it works, if the stiffness is not big enough, mould crack will easyly appears. To solve this problem, we also should notice the mould structure, must ensure big stiffness and strength of mould

(4)  High brittleness of the mould material will make mould crack and the method to avoid.

Some material with high brittleness, we heat the material slightly, the HRC will be very high, Such as carbon steel material. So we should choose material with excellent toughness for mold manufacturer.

Thinwall Injection Mould

Thinwall Injection Mould

In order to produce the new parts any sorts of machine, Moulding process is utilized. Moulding process helps to generate the strong and worthy parts easily and instantly. Bi-color injection mold is preferred by many companies, as it will produce the component in two colors. The components, which produced in this model, will be more attractive. Mostly, toys, dolls, toothbrushes, buttons, switches will be prepared using this model. Apart from Bi-color injection mold, BMC molding and thin wall Injection molding products also have more fame among the people. The important and specialty of this process exist in the selecting the color combination. If the color combination matches well, the certain product will reach the customers in large amount and its market ranges increases a lot.

BMC injection moldings products will be more strong and stable. Thus, the plastic mold components required for the transportation, sports, electrical related works are prepared using this moulding process. The materials prepared using the BMC molding process will be very flexible and they can be extended easily. BMC objects will be great in withstanding the heat for long time. Thus, electrical appliances are mostly prepared using this model, in order to get the heat withstanding capacity. BMC material will remain constant upto 130 degree of heat. Also, BMC material will not be wasted soon and they can remain for long period without any damage, if it is handled carefully. During BMC molding, the essential materials should be mixed in the perfect ratio and suitable temperature should be applied. Then only it is possible to procure the stretchy and reliable BMC materials.plastic mold

Thinwall Injection Mould to make Thinwall Injection Mold molding parts, the process is not that much easy process as like other molding process. In order to generate the thin products, this molding process is utilized. Using this process, large number of components can be prepared in a short period. Mostly to produce the electronic components like mobile, laptop and computer parts, this molding process will be used.

As Chinese people prefer the plastic utensils in large amount, there is large demand for the plastic utensils in china. The thin plastic utensils are prepared using the Thinwall Injection Molding process. High speed plastic molding machines, thin wall moulds are very essential to carry out this process. Along with these parts Robot system also should be available to execute this process successfully. Robot system performs the work of lifting and placing the molded material carefully in one place.

Chinese Molding companies are very careful in producing the products using the moulding process. They incorporate the high quality materials during the moulding process to procure the quality rich products. Thus, the molding products created by the Chinese companies are very reliable and worthy. Not only they concentrate in materials to be incorporated but also they will focus on mold machine, mold design, cooling system and so on. They will pay attention on each and every thing. These reasons play an important role in delivering the Chinese molding products in market in large amount. Since, molding process is performed with help of machines; the shape of the products will be accurate.
