Die Casting Tooling Construction and Design

Die casting tooling construction and design. In die casting procedures, the die casting tooling takes an important role. The tooling is the equipment that forms the product, and in the case of die casting in auto industry the tooling will help shape the auto part or accessory. This is also known as the die and the product is often made from the alloy tool steels and will have two general sections. In other tooling, it will have more than two sections.

The first section in the diecasting tooling is the fixed die half or the cover half and the second major component of the tooling is the ejector die half and this tooling component will allow for the removal of the castings. The casting may be crafted from a variety of materials. Some popular materials used include the non-ferrous metals like zinc, copper, aluminum, magnesium, lead and the tin-based alloys.

Aside from the two distinct components in most tooling, some dies will also feature that moveable slides and sections so as to produce other characteristics on the finished products. There will be holes in the fixed die half and these holes will allow for the entrance of the molten metal into the cavity. The cover half on the other hand will have passageways that can route the molten metal into the cavity. To ensure that no amount of molten metal will get out of the cavity, the die cast tooling will also feature locking pins. Ejector pins can be observed too and these pins will help remove the cast part.

Die Casting Molds 101: How The System Works

Die Casting Molds 101: How The System Works.

Die casting molds can be called by a host of names including die casting tooling, die casting dies or even insert dies. However, to simplify matters, these die casting molds may be simply referred to as “die casting tooling”. Regardless as to whether the dies are used in cold chamber machine production or hot chamber machine production, the principle behind its use is the same.

Die casting tooling molds come in two halves: the cover half and the ejector half. These two pieces are usually secured with locking pins that are now automatically fastened and released. The cover half is the immovable part. This remains as is all throughout the operation and usually does not contain any holes or passageways. The ejector half, on the other hand, can be detached during production since this is integral in the automatic ejection of the pieces within the dies. This half also contains spruce holes where the molten material is allowed to be squeezed through and eventually fill up the die cavity.

With more sophisticated dies, especially those that are designed to have pieces that have holes and tubes running within, the ejector half usually contains the gates (inlets) and runners (passageways) where it can route the molten material to. When the molten has taken the desirable shape, die casting mold tooling usually utilize ejector pins to automatically remove the pieces from the dies. Some machines even have openings for coolants (to speed up the cooling process considerably) and lubricants (in preparation for the next stage in production.)

Die Casting Mold Processes

Filed under: Die Casting Tooling — Tags: , , — admin @ 6:47 pm

Die Casting Mold Processes. Die casting has a similarity to permanent mold casting. The exception is metal is injected into the mold or die casting mold under the high pressure which results to a good surface finish and accurate dimension. Die casting can use cold chamber or hot chamber process.

In a cold chamber process, molten metal is gradually transferred into the cold chamber for every shot. This is useful especially for metals like Aluminum, Copper and its alloys. There is less time exposure of melt to the plunger.

In a hot chamber process, the pressure chamber is connected to the die casting tooling cavity. It is permanently immersed in the molten metal. Pressurizing cylinder inlet port is uncovered as plunger moves to open portion, which allows molten metal into the cavity. This hot chamber is useful for metals of low melting point and high fluidity. Examples are Zinc, Tin and lead that does not alloy easily with the steel.

Die casting molds and tools have a tendency to be expensive because they are produced from hardened steel and has a long cycle time to build. Also, iron and steel are very strong and hard metals and therefore cannot be die cast.

Zinc has high melt fluidity and can therefore be made to close tolerances and with thinner walls than Aluminum. It is alloyed with Aluminum and this makes it hard and strong. Casting is at fairly low temperature (425ºC). Zinc alloys are used to manufacture precision parts like connector housings, sprockets, gears, etc. Copper alloys are useful in electrical, marine and plumbing. They are corrosion and wear resistant.

Die Cast Mold Tools

Die Casting Molds and Die Casting Tools. There are several different Die Cast Molds Tools used for the process of die casting. They can be very expensive but the returns are also great as die casting is known to generate a lot of revenue for metalwork companies which have led for it to become top if the industry in terms of revenue.

Die casting is a process used by manufacturers in the metalworking industry in order to turn molten metal into parts or whole products for their clients. The best application for this process is to fulfill large orders for the same part of the same size, shape and dimension. This results in smooth surfaces of the part, good quality detail and consistent dimensions. The process has known to work so well to a point that it post machining can be removed entirely.

The main Die Casting Molds Tools that remain to complete the process are molds, hot chambered machines and cold chambered machines. The molten metal is first forced into the mold under high pressure before the die casting mold is machined into a die cast tool. Both hot chambered die casting machines and cold chambered die casting machines have different pros and cons. The former is known to work faster compared to the cold chambered machine however the hot chambered machine cannot be used for all types of metal alloys namely zinc, aluminum, magnesium and copper alloys.

These Die Casting Tooling can be a bit expensive, but they are worth every penny as they proved the manufacturer with better profits and revenue.

Better die casting molds

Filed under: Die Casting Tooling — Tags: , — admin @ 4:24 pm

Better die casting tooling from new materials could benefit auto manufacturers. The dies or the die casting molds are expensive parts since these are made from hardened steel. Another reason that contributes to the parts high-price range is the kind of production that is involved in making these die casting tooling molds. The cycle time that is used in building these products is long too. And finally, an important reason why these items are expensive is that the stronger and the harder metals like iron and steel cannot be die-cast. For this reason, these products are highly expensive in the market and this is true for one sector like the automotive industry.

For example, in the auto industry, the traditional die-casting molds that are made from hardened steel and those that are used in making the engine blocks and other auto parts and accessories can reach $500,000 or more. The equipment is pricey and it takes time to build. And this is one issue in the industry that has made some lives of the manufacturers a bit harder. But there is a new breed of materials that is now available in the market that can be used to address this issue. These new batch of materials are materials that can withstand the heat and at the same time not compromising its durability.

According to one researcher, these materials are called the functionally gradient materials. These materials have the capability to shift from one material to the next. And if the future die casting tooling molds are to be created using these materials then the usual cracking expected on the die casting molds can be removed. Plus products like auto parts and accessories made from the molds will have a longer lifespan.
