This guide covers everything you need to know about die casting mould.

Whether you want to learn about design, features or specifications – you will find all information right here.

So keep reading to learn more.

What Is Die Casting Mould?

Die casting mold is a tool made of firm steel or hard steel consisting of a cavity, core, and ejection system.

You use a Casting mold to fabricate casting components by pouring the liquefied metal into the Die casting mold cavity.

After this process, you will wait for the liquefied metal to cool so that it solidifies to desired die casting parts.

How Do You Make Die Casting Mould?

Firstly, you come up with the design you want basing on the analysis of the product’s material, structure tolerance, and other needed requirements.

Then look at the layout of the product, ensure all the lifters is accurately placed, and secure movement of sliders to move smoothly.

Then source for the mold base, steel, and other accessories first.

The second step Follow by removing excess matter-

Remove 95% (percentage) of excess material from the mold core, cavity, or sliders when utilizing the machine.

On the 3rd step, proceed to do a heat treatment on the mold-

Because the die casting mold tool needs to withstand elevated temperature when casting or In the casting process.

So that you harden casting mold, you will use a heating gadget depending on the life of mold; this is called heat treatment.

After heat treatment, proceed to drill or wire cut or milling-

Use the machine to give accurate dimensions and component characteristics while considering the shrinkage rate; it is the primary fabricating process.

Then polish die casting mold as this is a necessary process to achieve a good appearance on the surface of the mold.

Afterward, proceed to send the mold to the assembly and trial stage-

And this is where you fit and check all parts in assembly if it’s correctly done and try them if they work.

The final is when you look if there was interference during casting and the shrinkage rate of the design, mold cavity, slider, and other accessories.

What Are The Components Of Die Casting Mould?

It has two major components, the stationary and the ejector mold halves.

The stationery is on the machine, while the fixed plate ejector is on a movable fixing plate.

On casting, two mold halves are closed in the machine by die locking force; the contact surface between two is called mold parting.

These opening and closing movements, which apply to the ejector die cavities, are remolded by mechanically operated core slides.

Some other parts include;

Short sleeve, retaining insert, clamping slot, plate cavity, overflow, venting passage, vent insert, return pin, gold pin, safety lock, etc.

Runner plate, B-plate, core, heel block, ejector pin, ejector plate, ejector retain plate, water connector, support pillar, and the rails.

Which Are The Best Die Casting Mould Material?

Steel die casting mold.

Aluminum die casting mold.

Primary die molding metal is very lightweight and gives accurate dimensional stability, making it an excellent choice for complicated components.

518- It is good corrosion resistance; this gives you the ability to produce products like aircraft hardware fittings, decorative hardware, and escalate components.

How Do You Choose Die Casting Mould Design?

You have to consider some factors before deciding on the die casting mold design; they include;

Die draft, fillets, parting lines, bosses, ribs, holes and windows, symbols, and wall thickness.


The extent to which mold core is taper; you need an accurate draft to eject cast from die smoothly.

But because draft differs according to wall angle, characteristics like molten type alloy, wall shape, and mold depth effect process.

You should ensure that the untapped holes are air taped because of shrinkage; inner walls need more drafting because they also shrink.


The filter is a concave junction, and you use it to smoothen angled surfaces and make them round on edges.

Because of the role of smoothing surfaces, fillets will help you fabricate components with no errors;  add them anywhere on mold.

Parting line

It would help if you considered parting line because it joints various mold sections as one, ensuring part-line not deformed from work –station.

The deformed part-line leads to a gap in between, making the material drip out of the opening, giving a non-uniform molding.


In your mold design, bosses are die-cast knobs that have a purpose as mounting points or stand-offs.


You should ensure that the ribs are in use to improve matter strength in molds that don’t have the required wall thickness.

Rib placement helps decrease the chance of cracking and non-uniformity in thickness; it assists you in reducing weight and fills capabilities.

Holes and windows

Adding properties like overflow, flashovers, and cross-feeders is essential when you want to prevent unwanted casting around the holes.


It is a brand name, product logo, mold design of the die-cast mold, it affects most of your production costs.

You will need an extra liquefied metal on every fabricating part to cover the logo or brand name.

It gives you more cost results in more molten metal than recessed symbol, which needs few raw materials.

How Do You Clean Die Casting Mould?

First, consider laying out a mold cleaning plan for the different components like internal press cleaning, edge wiping, routine cleaning, and central clearing.

Use various cleaning methods to those parts to help you achieve the goal of cost-effectiveness.

The next is to do an appearance test of electroplating wear, track marking, and residual content of the vent and non-vent places.

Afterward, the technician will decide on the cleaning procedure and the frequency of cleaning by inspecting the appearance.

The reason for appearance inspection is to help one understand the operation cycle of mold to report residual accumulation and wear in mold.

For example, when you want to clean aluminum die casting mold, you will have to follow these stated steps here down below-

Use kerosene to clean mold; the reason is to ensure that there is no dirt at corners, holes, and other places.

Follow by drying mold using compressed air to ensure the limit switch and plug position is entirely free and dry.

Then inspect mold parts and transfer the defective components to the mold repair area in time.

Then follow by applying an anti-rest oil to the guidepost, guide sleeve, cavity, parting surface, and various sliding parts.

Ensure that you store the mold in the mold storage area to be fixed on position and stored, fill out mold handling repair and maintenance.

An excellent method to use when cleaning mold is the top to down principle to eliminate all-aluminum slag, oil, dust.

Fabrication of automotive products, the die casting mold makes gear, cylinders, small engines, glad hands, transfer cases, and components used in vehicles.

You can utilize casting mold in the fabrication of aerospace parts because it is economical and gives light and quality products.

What Determines Quality Of Die Casting Mould?

Design of mold is among one of the factors that determine the quality of the mold, and they are stated and explained below-

Design of casting mold

As a designer, you must first understand the users’ requirements and working conditions of the die casting mold system and the stress.

Then choose the suitable material according to the uses needed on the working condition and understand the material performance.

In design, pay attention to detail when making casting mold structure of the wall must be accurate and straightforward.

Ensure that the wall thickness is uniform and smooth, and the reservation of die inclination is also necessary when designing.

If you don’t follow this during design, you will have defects such as air holes, pit, and shrinkage porosity.

Dimensional accuracy is a requirement because it would lead to problems with the design, which causes the volume production of low-quality products.

Die structure, Machining accuracy, and Die Material selection-

The sign you choose and how you process the die-cast mold will relate to the quality of the product.

It becomes challenging to make a product qualified when die-cast mold structure is not reasonable; it won’t matter precautions you take.

Quality of product is affected by the accuracy of manufacturing, surface roughness, and the die material micro-crack of heat treatment.


When designing mold, pay extra attention to material shrinkage; it’s essential to make mold tests before manufacturing them in volume.

Ensure that you know the type of material you choose to work with and the shrinkage percentage of fabric with a temperature change when designing.

Formulation and implementation of die casting mold process-

This stage is critical as it is related to the quality of die-casting equipment and the technical level of operators.

Ensure that the processes and the main parameters are actually not carried out strictly; die casting gets shrinkage deformation, under-casting, and unqualified dimensions ion.

How Do You Maintain Die Casting Mould?

Check mold components and essential dimensions because running a machine for a long time may need repair to damaged parts.

After this, clean up components, check if there is residue matter in the cavity,  check the material runner if it’s clean, and ensure the parting surface of the mold is neat.

Then you scrutinize the cavity surface to see if there is water or rust, then polish again.

So to prevent rust right after the cleaning, you will proceed precisely to apply the anti-rust oil on the cleaned surface.

Then maintain mold by removing the residual cooling water in mold and residual oil in pipe fixing moving plate with locking plate to prevent opening.

Afterward, place it inside the mold storage, which is flat, dry,  clean, and convenient for handling and lifting when needed.

What Are Some Of The Die Casting Mould Principle?

Die casting mold adapts to the needs of casting production, gating system and overflow is selected following the die casting process.

The flow of molten metal is smooth and stable; the gas produced is gotten rid of in the cavity to have a good filling and prevent defects in the mold.

To enable safe production of die-cast, the quality and stability of die casting need to have the following features-

Ensure the structure of die mold is simple, advanced, and reasonable, this enables the process to be accurate, reliable, and procedure reduced.

It is pretty easy to operate, fast, safe, easier to dismantle components maintain, and has low cost in the manufacturing.

The efficiency of die casting is high, filling mold is fast, operating well, reliable and flexible demounting mechanisms with a high degree of automation.

The die requirement is the mechanical processing and heat treatment process, selecting suitable materials with thermal deformation, corrosion, and fatigue strength.

Mold design fits your economy and feasibility other than being generally low costly; it has a simple overall mold structure.

You should choose a practical dimension that matches the accuracy and is economical and decrease consumption of surplus matter in the pouring system.

It should have been formed enough not to cause deformation or deform under the force of clamping of the die casting machine.

Mold must be lightweight or not too heavy for conveniences when loading and unloading, repairing, and transporting, reducing load.

To prevent rough edges loose mold locking, the pressure center of the die cavity must be close to the center of clamping force.

The shaping of the die is matched with a specification of the die machine, ensuring that length and width will not interfere with the ejector.

Mould thickness should be medium, not too thick or too thin that is above the range of clamping of die casting machine.

Pay attention to matching the material pipe or nozzle and putting ejection mechanisms back using a pull rod.

Screw-in lifting ring screw on both sides of the fixed die, making die to facilitate assembly of mold and handling.

Can You Recommend Die Casting Mould Design Tips?

First, you have to understand the structure, application of die casting mold, the use, and assemble with other structural components.

Consider the structural characteristics and the performance of the casting die to differentiate the primary and secondary in the mold design.

Then highlight die structure focus and join with manufacturing technology of die, you select parting surface, quantity, the layout of the cavity, and ejection.

It would help if you also understood the capability processing of the mold like the existing equipment and equipment of co-operation unit level of operators.

After understanding all of this, you then combine the actual design of the mold structure in line with the field processing capacity.

It would be best to consider the temperature effects and influence of die temperature change on the accuracy fitting of sliding parts.
