Die casting parts

Die casting is an industrial casting process for manufacturing cast parts of aluminum, zinc, magnesium or brass. The molten metal is pressed under high pressure into the die where it hardens and is then automatically ejected. A die casting diecan contain several cavities. Depending on the die, series ranging from approximately 300 to 400,000 molded parts can be produced due to the high output of the dies. Die casting allows parts to be manufactured with very thin walls and smooth surfaces and edges. Due to the high strength, very good dimensional accuracy and reproducibility, die casting is the optimum casting procedure for complex components and demanding applications, both in terms of quality and economy.
To achieve superior quality, we use CNC machining centers to finish the cast parts. If desired, we will add tailored components to your diecast parts in additional production steps and will assemble these into modules and assemblies.
Die cast components are used in many branches of industry for housings, covers, fittings or mountings. Depending on the requirements, we supply die cast surfaces for decorative uses, improved corrosion protection or improved wear resistance.
Depending on the alloy and finishing process, die cast parts can be provided with the following surfaces: Sandblasting, glass bead blasting, barrel finishing, brushing, polishing, phosphating, passivating, powder coating, wet painting, eloxating, copper plating, nickel plating, screen printing or pad printing.

Can cast aluminium be welded, and if so, what techniques are used?

Yes, cast aluminium can be welded, but it requires specific techniques and considerations due to the unique characteristics of the material. Here’s a detailed explanation:

Cast aluminium is a commonly used material in various industries due to its lightweight, high strength-to-weight ratio, and good corrosion resistance. Welding cast aluminium can be challenging because it has different properties compared to wrought aluminium, primarily due to its microstructure and the presence of impurities and inclusions.

When welding cast aluminium, several important factors should be considered:

  • Preparation and Cleaning:
  • Prior to welding, thorough cleaning of the cast aluminium surfaces is crucial. Any contaminants, such as oils, dirt, or oxide layers, should be removed to ensure proper fusion and minimize the risk of defects in the weld.

  • Preheating:
  • Preheating the cast aluminium part can help reduce the thermal stresses and minimize the potential for cracking during welding. The preheating temperature and duration depend on factors such as the alloy type, part thickness, and welding method.

  • Welding Techniques:
  • Various welding techniques can be used for cast aluminium, including:

    • Tungsten Inert Gas (TIG) Welding: TIG welding is commonly used for welding cast aluminium. It involves the use of a non-consumable tungsten electrode to create an electric arc, and a shielding gas (typically argon) protects the weld area from atmospheric contamination. TIG welding allows precise control of the heat input and produces high-quality welds.
    • Metal Inert Gas (MIG) Welding: MIG welding, also known as Gas Metal Arc Welding (GMAW), can be used for cast aluminium. It utilizes a consumable electrode wire and an inert gas shield to protect the weld pool. MIG welding is faster than TIG welding but may require more expertise to achieve good results with cast aluminium.
    • Fusion Welding: In some cases, fusion welding techniques like oxyfuel gas welding or plasma arc welding may be suitable for specific cast aluminium applications. These processes involve the localized melting of the base metal to create the weld joint.
  • Filler Material:
  • The choice of filler material for welding cast aluminium is crucial. Generally, an aluminium-silicon alloy filler wire, such as 4043 or 5356, is used. These alloys have a similar composition to most cast aluminium grades and provide good fusion and mechanical properties.

  • Post-Weld Heat Treatment:
  • After welding, post-weld heat treatment (PWHT) may be necessary to relieve residual stresses and improve the mechanical properties of the weld. The specific PWHT requirements depend on factors such as the alloy composition, part thickness, and application.

  • Weld Quality and Testing:
  • Proper inspection and testing of the welds are essential to ensure their quality and integrity. Non-destructive testing methods, such as visual inspection, dye penetrant testing, or radiographic examination, can be employed to detect any weld defects or discontinuities.

It is important to note that welding cast aluminium can be more challenging compared to welding wrought aluminium due to the potential for casting defects, such as porosity or inclusions, which can affect the weld integrity. Therefore, it is advisable to work with experienced welders who have expertise in welding cast aluminium and understand the specific challenges associated with the material.

In summary, cast aluminium can be welded using techniques such as TIG welding, MIG welding, or fusion welding, provided proper preparation, cleaning, preheating, filler material selection, and post-weld heat treatment are considered. By following appropriate welding procedures and conducting thorough quality inspections, reliable and structurally sound welds can be achieved in cast aluminium parts.

What types of finishes can be applied to cast aluminium?

Cast aluminium can be finished with various types of coatings and finishes to enhance its appearance, protect it from corrosion, and provide additional durability. Here are some common types of finishes that can be applied to cast aluminium:

  • Paint:
  • Painting is a popular finishing option for cast aluminium. It allows for a wide range of color choices and can be used to achieve different textures and finishes, such as matte, glossy, or metallic. Paint provides both aesthetic appeal and a protective layer to shield the aluminium from environmental factors.

  • Powder Coating:
  • Powder coating is a dry finishing process where a fine powder is electrostatically applied to the cast aluminium surface. The powder adheres to the metal and is then cured under heat, forming a durable, uniform, and smooth coating. Powder coating offers excellent corrosion resistance, impact resistance, and color options, making it a popular choice for outdoor furniture, automotive parts, and architectural applications.

  • Anodizing:
  • Anodizing is an electrochemical process that creates a controlled oxide layer on the surface of aluminium. It enhances the natural corrosion resistance of aluminium and provides a more durable finish. Anodized finishes can range from clear or natural to various colors, depending on the type of anodizing process used. Anodized cast aluminium is commonly used in architectural applications, electronics, and consumer goods.

  • Polishing:
  • Polishing is a mechanical finishing process that creates a smooth, reflective surface on cast aluminium. It involves using abrasives and polishing compounds to remove imperfections and scratches, resulting in a shiny and lustrous finish. Polished aluminium can be left untreated for a bright, metallic appearance, or it can be further coated or protected with clear lacquer or wax.

  • Brushed or Satin Finish:
  • A brushed or satin finish is achieved by brushing the surface of cast aluminium with abrasive materials or using mechanical techniques. This creates a textured, matte finish with visible brush marks. Brushed or satin finishes are commonly used in architectural applications, decorative elements, and furniture.

  • Antique or Patina Finish:
  • An antique or patina finish is designed to give cast aluminium a weathered or aged appearance. This finish is achieved through chemical treatments or special coatings that create an oxidized or tarnished effect on the surface. Antique finishes are often used in decorative pieces, art, and furniture to add character and vintage appeal.

The choice of finish for cast aluminium depends on the desired aesthetic, functional requirements, and the intended application of the product. Different finishes offer varying levels of protection, durability, and visual effects, allowing for customization and versatility in the use of cast aluminium.

How does cast aluminium differ from wrought aluminium?

Cast aluminium and wrought aluminium are two different forms of aluminum that differ in their manufacturing processes and properties. Here’s a detailed explanation:

Manufacturing Process:

  • Cast Aluminium:
  • Cast aluminium is produced by pouring molten aluminium into a mold or die, allowing it to solidify and take the shape of the mold. This process is called casting. Cast aluminium components are typically created in large batches using specialized casting techniques such as sand casting, die casting, or investment casting.

  • Wrought Aluminium:
  • Wrought aluminium is produced through a series of mechanical processes, typically starting with the casting of ingots or billets. The ingots or billets are then subjected to various shaping processes, such as rolling, extrusion, forging, or drawing. These processes deform the aluminium material and shape it into the desired form, such as sheets, plates, bars, or profiles.

Mechanical Properties:

  • Cast Aluminium:
  • Cast aluminium has a coarse-grained microstructure due to the rapid solidification process during casting. This microstructure can result in lower mechanical strength and reduced ductility compared to wrought aluminium. However, cast aluminium can still exhibit sufficient strength and rigidity for many applications.

  • Wrought Aluminium:
  • Wrought aluminium has a refined and more uniform microstructure due to the mechanical processing it undergoes. This results in improved mechanical properties, including higher strength, better ductility, and enhanced toughness compared to cast aluminium. Wrought aluminium is often preferred for applications that require superior mechanical performance.

<strong.Surface Finish:

  • Cast Aluminium:
  • Cast aluminium surfaces typically have a textured or slightly rough appearance due to the nature of the casting process. The surface finish of cast aluminium can vary depending on the casting method used and the quality of the mold. Additional machining or surface treatments may be required to achieve a smoother or more polished finish.

  • Wrought Aluminium:
  • Wrought aluminium surfaces can achieve a smoother and more refined finish compared to cast aluminium. The mechanical processing involved in the production of wrought aluminium helps create a more uniform surface texture. Wrought aluminium can be further treated or finished to achieve various surface qualities, such as brushed, polished, or anodized finishes.

Application Suitability:

  • Cast Aluminium:
  • Cast aluminium is commonly used for applications that prioritize ease of manufacturing, complex shapes, or cost-efficiency. It is often found in automotive components, household appliances, decorative items, and low-stress structural applications.

  • Wrought Aluminium:
  • Wrought aluminium is preferred for applications that require superior mechanical properties, tight tolerances, or specific surface finishes. It is commonly used in aerospace components, high-strength structures, precision parts, and applications where formability and strength are critical.

It’s important to note that the choice between cast aluminium and wrought aluminium depends on the specific requirements of the application, considering factors such as mechanical performance, surface finish, complexity of the design, and cost considerations.
