Permanent mold castings

Gravity die casting is the ideal choice for producing high-quality, durable, and precise castings with excellent surface finishes. We achieve tight tolerances and consistent quality, making this process perfect for medium to high-volume production. Our expertise includes casting a wide range of non-ferrous metals, such as aluminum and bronze.

We deliver ready-to-use parts. Gravity die castings often require further processing, including machining and surface treatments. With our advanced machine shop and trusted network of surface treatment partners, we ensure that every casting meets the highest customer expectations.

Permanent mold casting ALLOYS

Material properties and characteristic are selected for each casting individually, depending on its application. In casting process, we melt and mix different materials to make the best alloy for your project. Wide range of alloys we cast will suit any application. Our engineers will help you to choose the right alloy.

MEDEKO Investment casting materials:
  • brass materials
  • copper materials
  • aluminum materials

Quality

Our quality management relies on an integrated quality management system conforming to ISO 9001:2015. We are also holders of certificates ISO 14001:2015, ISO 45001:2018, and P.E.D..

HEAT TREATMENT

Permanent mold casting finishing.
Raw castings are considered as parts cut off from feeding system, blasted of ceramics and quality inspected. They can be further processed or used as raw. Heat treatment is thermal process of altering physical properties of casting.

Surface treatment

Permanent mold casting finishing.
Surface treatments for gravity die castings made from copper, brass, and aluminum are essential to enhance their properties, such as corrosion resistance, wear resistance, and aesthetics. Here’s a detailed overview of the common surface treatments for these metals:
Electroplating: Applies a thin layer of another metal (such as nickel or chrome) to improve surface hardness, corrosion resistance, and appearance.
Passivation: Creates a protective oxide layer on the copper surface to enhance its natural corrosion resistance.
Polishing: Enhances the surface finish and appearance, often used for decorative applications.
Painting/Coating: Adds an additional protective layer, often used in environments with high corrosion risk.
Lacquering: Involves applying a protective lacquer to maintain the polished appearance and prevent tarnishing.
Powder Coating: Applies a durable, protective, and decorative coating through an electrostatic process followed by curing under heat.

Machining

Mechanical processing of gravity die casings is done by our advanced machine shop in-house.
Our aim is to deliver ready to fit castings to our customers. Our advanced machine shop contains wide range of CNC centers, turning centers and grinding machines. Some of our customers are using our assembly center, where castings after machining are assembled and delivered to customer as ready to install units.
