Quick considerations for selecting a die casting manufacturer

Die casting is recognised as one of the most economical and fastest forming processes in the industrial sector. Its advantages include the mass production of many different kinds of products.

In this process, liquid metal is pressed into a mould at a high filling speed and under high pressure. The materials most commonly used by a die casting manufacturer are metals with a low melting point. The result is the large-scale production of complex components characterised by thin walls.

Employing the services of a good die casting manufacturer is crucial to achieving your production or industrial objectives. Choosing the right supplier for your firm can be a challenge.

To help streamline your decision-making process, here are five criteria to keep in mind when selecting a die casting manufacturer.

5 quick considerations for selecting a die casting manufacturer

Keeping these five tips in mind can help you make a selection that is most closely aligned with your organisation’s objectives and interests.

1. Complete solution provider

It is critical to find a supplier that is not limited to providing raw castings. A good provider will be able to deliver products that can go directly into your final assembly line. This may include painted, polished or machined components that are individually produced and finished.

2. Simulation

A good die casting manufacturer will be able to create excellent simulations on screen. These simulations show you how the mould is filled during production. A crucial benefit of simulation is that defective areas can be identified immediately. This allows you to take corrective measures well in advance of the next step of the production process.

3. Quality of machinery

A state-of-the-art die casting manufacturer will have high-quality machinery designed to cut the exact shape in hot-work die steel. The right machines will be able to cut to very close tolerances. As a result, the final product will not require much machining and will be of high quality.

It is also important to note that different kinds of products require different sizes of die casting machine. This depends on the weight and projected area of the final product. It is therefore necessary to find a supplier that has a wide variety of machines.

4. Right kind of material

Creating a mould or die requires an excellent venting system that can produce sound castings. A good die or mould contributes significantly to the quality and number of products created. For example, an HPDC die can produce almost 100,000 usable parts. It is therefore important to select the right material that can withstand the continuous production of 100,000 parts.

5. Final surface treatment

As the last part of the production process, a good die casting manufacturer will ensure your products receive adequate surface treatment. This is primarily done via painting or powder coating, and it significantly improves the appearance, reduces the effects of oxidation and covers any defects.

Keeping these five considerations in mind can help you find a die casting manufacturer that is aligned with your interests and goals. Be sure to do your research thoroughly before making a commitment, so that you are equipped and prepared for the next stage of finalising the deal.

Understanding the advantages of the die casting process with regard to your production requirements can also help you make a structured decision (taking all relevant factors into consideration).

Advantages of die casting – what you should know

Die casting is one of the most economical and efficient processes in industry, offering a broad range of shapes for different components (unlike other manufacturing techniques).

Parts produced by die casting also have a long service life and can be designed to complement the aesthetic appeal of the overall product.

Understanding the advantages of the die casting process can help you make a wise decision before making a financial commitment.

Some of the excellent benefits of the die casting process include:

• The die casting process allows the production of complex shapes within closer tolerances than many other mass production processes.
• Die casting also allows significantly higher production rates, with the advantage of minimal machining.
• An excellent advantage of the die casting process is the production of parts that are dimensionally stable, have a high-quality appearance and feel, and are extremely durable.
• Die castings can also be produced with thinner walls than castings produced by other methods. The final product is also significantly stronger than plastic injection mouldings of the same dimensions.
• Without any additional tooling, die casting dies can produce thousands of identical castings within a specified range of tolerances.
• Another advantage of the die casting process is that it can produce surfaces designed to simulate a wide variety of textures.
• Die-cast surfaces are also significantly smoother than those produced by other casting methods, such as investment casting, permanent mould casting and sand casting.
• The corrosion resistance of die-cast alloys ranges from good to extremely high.
• Die castings are also monolithic. This means they combine many different functions in one complex-shaped part. Because die castings do not consist of separate parts, the strength of the material is also significantly higher.

While the advantages of the die casting process are plentiful, understanding the disadvantages involved can help you determine the next course of action.

For instance, alloys and metals with a high melting point cannot be used in the die casting process. Additionally, any gases trapped in the mould can result in porosity.

When choosing your die casting manufacturer, it is important to ensure that all quality criteria are met. Do your research and consider discussing the quality of products and services with previous clients. This can help you determine whether the manufacturer is suitable for your requirements. All relevant information should be available on the manufacturer’s official website.
