Process

Die Casting

Die casting is a manufacturing process used to produce metal parts with high precision, dimensional consistency, and complex shapes. It involves injecting molten metal into a mold, known as a die, under high pressure. Once the metal solidifies within the die, the mold is opened, and the solidified part, known as a casting, is removed.

Die casting excels in creating intricate, precise parts and is commonly employed for large-scale production. Advanced methods like squeeze casting and semi-solid metal casting further enhance the quality of the parts produced. Notably, around 80% of die cast parts are crafted from aluminum, showcasing its widespread usage

Die Casting Types Available from Kintec

Kintec uses modern die casting technology to provide top-quality parts whenever needed. We specialize in two main types: hot chamber and cold chamber casting. These methods create parts with complex shapes, precise measurements, and strong properties, serving diverse industries

Hot Chamber Die Casting

Hot chamber die casting, using metals like zinc and magnesium that melt at lower temps., starts with molten metal in a heated pot. A gooseneck channel connects to the mold's cavity. A plunger fills the chamber with metal, then pushes it into the mold. Pressure and cooling create the part. This method is popular for its efficiency.

Cold Chamber Die Casting

Cold chamber die casting doesn't need a hot chamber. Metal is melted in a separate furnace, then added to the shot chamber with a ladle. The mold connects to the shot chamber. A ram pushes molten metal into the mold, under high pressure. This works well for metals like aluminum with higher melting points.

Advantages of Die Casting

Die casting is fast and efficient, creating parts quickly with little waste. This suits mass production and cost-effectiveness. It achieves precise details and smooth surfaces, ideal for complex shapes. This minimizes the need for additional finishing, maintaining low costs. Die cast parts are durable, offering longer lifespans than other components.

Aluminum Die Casting

For aluminum and other alloys with higher melting points, the cold chamber die casting process is used. In this method, the molten metal is ladled into a separate chamber, and then a hydraulic piston injects it into the die. The use of a separate chamber keeps the molten metal away from the machine’s plunger and nozzle, which prevents exposure to high temperatures that could damage those components.

Trimming, Deburring & Machining

After casting, excess material and sharp edges are removed to achieve the desired shape and enhance safety. Additional machining operations, like drilling, tapping, and milling, may be conducted for precise dimensions and features.

Zinc Die Casting

Zinc die casting is a manufacturing process used to create metal parts and components from zinc alloys. It is similar to aluminum die casting but uses zinc as the primary material. Zinc alloys are applicable in part manufacturing due to their ductility, impact strength, and low melting point. Furthermore, the casting process occurs under lower heat due to the material’s low melting point. Hence the name “hot chamber die casting process.

Surface Finishing

Applying various surface treatments to improve aesthetics and protect against corrosion. This includes processes like polishing, buffing, shot blasting, and sanding.

Materials

Choosing the right material involves considering factors such as the intended use of the part, mechanical properties required (strength, hardness, ductility), thermal properties, corrosion resistance, and cost considerations. Each material has its advantages and limitations, so consulting with our experienced engineers and material experts can help you make the best choice for your project.

Tolerance

Tightest tolerance: ±.0008’’ (0.020 mm) Tighter tolerances are examined on a case by case basis with your technical drawings. Kintech’s CNC machining service can produce CNC parts with tolerance as low as ± 0.0002 in. Without a drawing, all CNC parts are produced to our ISO 2768 medium standard. We can also machine to tighter tolerances, ±0.025mm or ±0.001″, with an attached engineering drawing calling out critical features.
