Moulds used in die-casting

proceso de cromado

Moulds are an indispensable and invisible part of the die-casting process.

At Funmak, we use them in materials such as zamak, either to create a component or a fully finished product.

Following this line, we can state that the mould is a vital component in the value chain.

If you want to find out more about moulds in die-casting, read on.

What is the injected function

Injection function is a manufacturing process for metal parts in which molten metal is poured or pressed into steel moulds. These moulds are designed for each project.

As a result, each component is created with precision and repeatability.

What is the injected function for

The benefits of using the injected function injection model include cost savings and total cost of production.

When casting a zamak part, complex shapes such as threads and complex geometries can be produced.

In addition, multiple metal parts can also be combined into a single part, eliminating assembly operations and reducing labour costs.

How the die-casting process is carried out

When it comes to the die-casting process, there is no single process that can be adapted to each project. Thus, at Funmak we offer different solutions for injection moulding.

There is no single injection moulding process for injection moulding, so here are two different types of injection moulding processes.

Hot chamber

The hot chamber is a great choice for alloys that do not easily attack or erode metal crucibles, cylinders and plungers.

Cold chamber

The cold chamber is usually the most recommended when working with high melting points. During this process, the metal is liquefied and then strained into a cold chamber where a hydraulically driven piston pushes the metal into the mould.

What are the benefits and alloys of die casting?

Zamak die casting can have advantages in manufacturing processes that often lead to significant cost savings. By casting metal parts, all kinds of shapes can be created.

In addition, multiple metal parts can also be combined into one, eliminating assembly operations and reducing labour costs.

Other benefits of this process are: Variable wall thickness, tighter tolerances, fewer production steps from raw material to finished part, fast production cycle times, reduced scrap material and long tool life.

As far as cast function alloys are concerned, these are non-ferrous metals and can be adapted to almost any type of application a manufacturer may need.

Cast alloys are fully recyclable and withstand high operating temperatures.

In addition, they enjoy other benefits such as: good corrosion resistance, high strength and hardness, high thermal conductivity, high electrical conductivity and good finishing characteristics.

How do we use the moulds when die casting?

The way we use moulds in die casting has a very simple process: thanks to their high creep, the material, in this case Zamak, is pushed into the mould under high pressure.

The mould cavity is completely filled, allowing the metal to enter any corner of the mould.

Each machine has a crucible into which the base material, which in this part of the process is in ingot form, is introduced and melted at a temperature of 430 °C. Once the Zamak is molten, it is injected into a die.

After injection moulding, the metal parts are automatically or manually separated from the feed channels by rotating drums installed next to the machines.

Moulds in the die casting process

At Funmak, we have a great deal of professionalism in the die casting process, as well as creating high quality parts for the market.

We also offer products made from Zamak material and you will be impressed by their effectiveness.
