Die Casting Mould Materials

Different aluminum die casting mould materials come with pros and cons, and various factors need to be comprehensively considered when selecting.

High Hardness Steel is suitable for manufacturing products that require high precision, high surface quality, and high wear resistance, but it comes with a higher mould budget and is easy to crack.

Heat Treated Steel has a long service life and excellent wear resistance, but has poor thermal conductivity and requires heat treatment.

Aluminum Alloy is lightweight, sturdy, and long service life, but the hardness and strength are not as good as the other two options.

When selecting, it is necessary to comprehensively consider production needs in order to choose the most suitable aluminum die casting mould material.

How Much Is the Die Casting Mould?

The price range of the die casting mould usually between $900 to $15,000 US dollars, and CEX always considers the appropriate mould materials based on the product structure and customer requirements. We design the mould structure, determine the number of mould cavities, and decide on the gate runner structure, etc.

For products with lower technical requirements, we may choose relatively economical mould materials and design fewer mould cavities to reduce mould developing costs. On the other hand, if the products require higher technical requirements, we use high-quality mould materials and increase the number of mould cavities to optimize the processing cost of unit piece.

In order to provide you with an accurate price, we will carefully evaluate the drawings and requirements. Our goal is to provide a quotation within 10-15 hours (excluding holidays) after receiving the necessary information.

Unique High Strength of Die Casting Mould Design

Technical Patents for the Design of High Strength Die Casting Mould

CEX’s unique gate design and liquid metal entry method ensure that the liquid metal completely fills the mould cavity and solidifies uniformly, avoiding air contact and achieving high-precision moulding.

Die Casting Tooling Lifespan

The service life of die casting mould is usually 80000 to 100000 cycles, which is closely related to the quality of the materials used and the heat treatment applied. In addition, factors such as the product structure and casting wall thickness also influence the service life. In general, moulds for castings with thicker wall thickness tend to have a relatively shorter service life.

Fortunately, there is no need to worry about what to do when the service life of the die casting mould ends. When working with CEX, you only need to bear the initial development costs. Our company is responsibie for the subsequent maintenance and re-moulding costs once the mould service life ends. If our production capacity with one set of moulds cannot meet the large volume requirements, CEX will cover the cost of developing another set of moulds to ensure continuous production without incurring financial burden.

Development Cycle of Die Casting Mould

The mould production cycle is usually 30-35 days. Behind a simple mould is a very complex process involving a lot of components. The mould production process is as follows:

Die Casting Mould Making Process

Drawing Review – Material Preparation – Processing – Mould Base Processing – Mould Core Processing – EDM – Mould Parts Processing – Inspection – Assembly – Mould Testing – Production

  • Mould Base Processing: numbering, A/B board processing, panel processing, ejector pin fixing plate processing, bottom plate processing
  • Mould Core Processing: fash cleaning, rough grinding, milling machine processing, bench worker processing, CNC rough machining, heat treatment, fine grinding, CNC finish machining, EDM, mould saving
  • Mould Parts Processing: slider processing, compression block processing, diversion cone gate sleeve processing, insert processing



What Are the Components of a Die Casting Mould?

The Cavity: giving shape to final product

The Core: creating internal features

Sprue and Runner: facilitating molten metal flow

Ejector Pins: ensuring smooth part ejection

Cooling Channels: controlling temperature and solidification

Venting System: preventing defects

Slides and Lifters: handling complex shapes

Can Die Casting Moulds Be Reused?

Yes, die casting moulds are typically reusable. Die casting moulds, also known as dies, are designed to withstand multiple casting cycles. They are made of durable materials such as steel or other alloys that can withstand the high temperatures and pressures of the die casting process. After each casting cycle, the mould can be cooled, cleaned, and prepared for the next casting. This reusability makes die casting an efficient and cost-effective manufacturing method for producing large quantities of parts.

What Are Permanent Mould Die Casing and Die Casting

Permanent mould die casting and die casting are valuable manufacturing processes used to produce metal parts. Permanent mould die casting offers cost-effective production of medium to large-sized parts, while die casting excels in its versatility for a wide range of part sizes and complexities. Both methods contribute to the efficiency and precision of modern metal part manufacturing across industries.
