Cold Chamber Die Castings – A Look at the Procedure

Cold Chamber Die Castings – A Look at the Procedure. Die casting is a process that is in one way or another like to that of permanent mold casting. The only point of distinction lies in the fact that the metal is essentially injected into the mold by utilizing a high pressure. This allows the production of a more precise dimension and better surface finish, so to speak. In many circumstances, the use of post machining can already be eradicated since the output is utterly awesome. Light machining methods may be necessary in some occasions just for the function of sizing up the dimensions. Now the cold chamber die castings are also among the many procedures utilized these days.

With the popularity of cold chamber die castings comes the value of zinc or aluminum alloy castings. It is owing to the reality that among other alloys, the zinc die casting alloys and aluminum have high melting points. The cold chamber is also known as the cylindrical sleeve and it is where the melted metal is dispensed. The medium utilized is either a manual hand ladle or an automatic ladle. There is also a hydraulically operated plunger which shuts the cold chamber port and then forces the metal straight towards the locked die utilizing high pressures.

In terms of the method of cold chamber die castings, the melted metal that is inputted into the cold chamber or cylindrical sleeves experiences a compact time exposure to the plunger or its walls. Along with aluminum parts, the brass parts die casting are also utilized along with iron because of their properties which are very much conducive for use with higher temperatures.

Cold Chamber Die Castings

Cold Chamber Die Castings. Die cast processes utilized in aluminum alloy like 380 aluminum, as materials provide work for machines planned for cold-chamber die castings. Throughout this cold-chamber method, the material is first melted in a detached furnace. From the melted metal, an exact amount is taken and encouraged into the cold-chamber machine to be fed into an injection cylinder or an unheated shot chamber. A mechanical or hydraulic piston then forces this shot into the die or mold.

The cold chamber die castings have a comparatively slower cycle time measured up to the hot chamber method, because of the time necessary in transferring the molten metal to the cold-chamber machine from the furnace.

Be that as it may, cold chamber die castings remain as an economical and well-organized method. There is a broad variety of aluminum parts like aluminum heatsinks and aluminum hardware that could be fashioned from this process. Long-lasting service may be derived from these cold chamber die castings as aluminum is not only light but is also tough and non-corrosive. Mass production of parts at comparatively quicker speed is similarly probable as the components already come out in their net shapes. Little or no further machining is essential as the cold chamber die castings by now roll out in their design specifications. The strength of the aluminum alloy is equally harnessed to the fullest with designs that need no welding of parts together. And even if there are components that require to be fastened, the dies or molds could integrate self-fastening holes and studs for a ideal fit of the parts, possibilities that make cold chamber die castings among the precious tools of contemporary industry today.

Kinetic Die Casting utilizes die casting to manufacture parts like aluminum car parts, airplane parts, lighting parts and much, much more. If you would like to request a quote, please visit our website:Die Casting quote

Porosity in Aluminum Die Casting Parts

Aluminum Die Casting Parts Porosity – Porosity in Die Castings

There are many forms of Die Casting Porosity, many are caused by these die casting variables:

  • Metal Temperatures and Mold Temperatures.
  • Material Cleanliness.
  • Die Casting Mold Design.
  • Die Casting Part Design.
  • Die Casting Machine Pressures.
  • Die Casting Machine Shot Speed.
  • Die Casting Spray or Die Casting Mold Release.
  • Other forms of porosity can be from “shrinkage” or wall thickness.

What is Die Casting Porosity? In order for you to know what die casting porosity is, you need to know the die casting basics. The most common form of Die Casting Porosity is a kind of factory defect in which die cast parts contain small pockets of void space and air within the metal, causing it to become porous.

Porosity in Die Casting is the air trapped by the metal inside the die casting parts. To know more, a basic knowledge of the die casting process is necessary. Die casting is a process wherein a particular amount of molten metal is put inside a shot cylinder, then it is applied (plunged) with great force with a piston so as to force the metal into a die cast mold or die cast die. During this “plunging process”, air inside the cylinder is forced along with the metal into the die casting mold. It is a very fluid turbulent process. The air forced into the mold with the metal and the metal already inside the mold is forced out of the mold through a series of gates, vents and overflows.

After this, the metal is left to cool down and harden or freeze inside the mold. The metal is then removed as a die cast part. The same process is repeated over again.

Die casting companies use metals which are non-ferrous, or do not contain Iron, as this is the highest factor for oxidation and rusting. Several examples of non-ferrous metals include zinc, aluminum, lead, magnesium, tin and copper. Kinetic Die Casting only uses aluminum and zinc.

In the worst case, porosity in die casting parts, weakens die casting parts, if the voids or pockets are very large. Porosity typically matters most in pressure tight die casting parts. When the air escapes through a die casting part, it is typically caused by porosity.

Employees of Kinetic Die Casting are POROSITY EXPERTS in die casting parts that need to be free of porosity.

Draft Angle in Die Castings

Aluminum Die Casting Parts Draft Angle – Draft Angle in Die Castings

When someone asks me “what is draft angle in a box?” or “why do I need a draft angle on my aluminum die casting box part?” The technical answer is, all aluminum die castings require a draft angle on the walls of die cast box parts perpendicular to the parting plane or parallel to the slide interfaces. Since I have selling die cast parts for over 20 years, I find simple answers and provide simple calculations for my customers. What does that mean to the typical engineer (any engineer other than tooling or mechanical) or professional buyer?

I try to give examples that most people can relate to, because most people do not have a need to concern themselves with how things are made, only what is made, and will it be what they need. I ask, “Have you ever noticed on a cupcake the bottom diameter is smaller that the top diameter?” or “Have you noticed that a cake pan has sides that slope in toward the middle of the pan?” That would be an extreme example of a draft angle. Aluminum die castings would stick inside the die casting tool, molds, or die casting die if there was not enough draft angle in the tool and part. The typical draft angle for an aluminum die casting part is two degrees per side. The calculation for that is simple if a person is familiar with die casting production part design, but is not familiar to most people.

Picture an enclosure (or Aluminum Box) sitting on a table with the open side up. The aluminum box is 2″ deep inside with the height and width 4″ each way on outside. The walls of the box are 0.10″ thick. Due to the wall thickness, a few things are evident to a part designer concerning this simple box:

  • The overall height of the box is 2.10″ tall.
  • The interior of the box at the top of the opening is 3.80″ x 3.80″.

A 2 degree draft angle will change the dimensions in the following on the interior and exterior and should be considered if something needs to fit inside the box or outside the box:

  • The top inside dimension of the box will be 3.80″ and the bottom inside will be 3.664″
  • The top outside dimension of the box will be 4.00″ and the bottom outside will be 3.864″

If the box was designed for the interior of 4″ x 4″ at the bottom: box:

  • The top inside box dimension needs to be 4.136″
  • The outside top box dimension will be 4.336″.
