Die casting is a manufacturing process used to produce metal parts by forcing molten metal into a mold (or die) under high pressure. Die casting is commonly used for producing high-precision, complex metal parts in large quantities. The process can work with a variety of metals, such as aluminum, zinc, magnesium, and others, offering advantages like high dimensional accuracy, smooth surface finishes, and fast production rates.
The die, typically made from steel, has cavities that form the desired shape of the part. The molten metal solidifies quickly within the mold, taking the shape of the cavity, and after cooling, the part is ejected.
YS Rapid excels in providing high-quality, custom die casting solutions that combine superior performance, precision, and speed, making us a trusted partner for your die casting needs.

YS Rapid offers both hot chamber and cold chamber die casting to accommodate a wide range of metals and part designs.
It involves submerging the injection mechanism in molten metal, allowing continuous feeding into the mold without needing to refill the chamber. It is highly efficient for producing smaller parts in large quantities, particularly with low-melting-point metals like zinc. The process offers faster cycle times due to the direct immersion of the injection mechanism, making it ideal for high-precision products .
It is ideal for metals with higher melting points, such as aluminum, and copper. The molten metal is poured into a cold chamber before being injected into the mold under high pressure. This method is particularly suited for producing durable, high-strength components with intricate shapes.
Pressure die casting is a versatile and highly efficient manufacturing process used to produce metal parts with complex geometries, high precision, and smooth surfaces.
Automotive Industry: Pressure die casting is used to produce high-precision engine, transmission, and structural parts for vehicles.
Consumer Electronics: It creates precise and aesthetically appealing parts for smartphones, laptops, and TVs.
Industrial Equipment: The process is used for making durable pumps, valves, and motor housings in industrial machinery.
Furniture and Lighting: Pressure die casting is used to create intricate and strong components for lighting fixtures and furniture hardware.
Electrical and Plumbing: It produces reliable electrical enclosures and plumbing fittings like faucets and valves.
Medical Devices: Used to manufacture precise instruments and components essential for ensuring reliability and sterility in medical applications.
Aerospace Industry: It manufactures lightweight, durable engine and structural components for aircraft.
Surface finish and dimension accuracy are excellent.
High density & strength. Die casting parts has a dense structure and high strength and hardness as the liquid metal is cooled and solidified under pressure.
High productivity efficiency. The die casting machine has high productivity. The filling time is extremely short and the cooling rate is extremely fast. And the lifespan of die casting mold is long, which can generally produce 60K-80K shots, sometime even as high as 100K shots.
Cost effective production. High material utilization. As die casting parts have the advantages of accurate size and good surface finish, they are general can assembled directly without machining, or only a small amount of machining is required, reducing a lot of processing cost. Its material usage rate is about 60%~80%, if not secondary processing, the utilization rate is about 90%. Therefore the price of die casting parts is cheap.
Metal parts with complex geometries can be made. Die casting can manufacture metal parts with complex shapes, clear contours and thin-walled deep cavities: because the molten metal is under high pressure and high speed, which maintains high flowability, which enables the acquisition of metal parts that are difficult to machine by other processes.
High Initial Cost: The setup cost for pressure die casting, including the mold and equipment, can be quite high, making it less suitable for low-volume production.
Porosity Issues: Cast parts may sometimes have porosity (tiny holes) that can affect the strength and integrity of the part, especially when casting metals that are prone to gas entrapment.
Limited Material Compatibility: Best suited for metals with lower melting points, as high-melting-point metals are difficult and less efficient to cast.
Design Limitations: Complex shapes with undercuts or intricate features may be difficult or expensive to cast due to the limitations of the mold and the die-casting process.
Size Restrictions: Pressure die casting is best suited for smaller parts; it may not be efficient or cost-effective for producing large components.
Die casting is a precision manufacturing process capable of achieving very strict tolerances, making it ideal for complex, high-volume parts. The tolerance range typically depends on the part's size, the metal used, and the specific casting process. For standard sizes:
Parts smaller than 25mm typically have a tolerance of ±0.1mm.
Parts up to 250mm in size generally have a tolerance of ±0.5mm.
With additional post-processing techniques, more precise tolerances of up to ±0.02mm can be achieved.
The material used plays a crucial role in defining tolerances, as metals like aluminum and zinc alloys have different shrinkage rates and mechanical properties, which can affect the final dimensional accuracy. Advanced die casting technologies, such as vacuum casting or squeeze casting, can further enhance tolerance control by reducing porosity and improving the integrity of the metal.
Pressure die casting is typically used for parts requiring high precision, strength, and a smooth finish. Some examples include:
Automotive Components: Engine blocks, transmission cases, and structural parts.
Aerospace Parts: Aircraft engine components and housings.
Electronic Enclosures: Housing for electrical devices like computers, phones, and lighting fixtures.
Consumer Goods: Parts for appliances, toys, and tools.
Die casting is a manufacturing process where molten metal is injected under high pressure into a mold cavity. The metal cools and solidifies, creating the part. The process can be broken down into the following steps:
Mold Preparation: The mold is preheated and lubricated to ensure smooth casting.
Injection: Molten metal is injected into the mold cavity at high pressure.
Cooling: The mold cools the molten metal, allowing it to solidify and take the shape of the cavity.
Ejection: The solidified part is ejected from the mold, typically using ejector pins.
Finishing: The part may undergo secondary processes such as trimming, machining, or surface treatments.
When designing a part for die casting, several factors need to be considered to ensure the product's quality, manufacturability, and cost-effectiveness:
Material Selection: The type of metal used will affect the design. Common materials for die casting include aluminum, zinc, and magnesium alloys.
Wall Thickness: Uniform wall thickness is important to prevent defects like warping and porosity. Thicker walls may require more material and lead to longer cooling times, while thinner walls may cause defects.
Draft Angles: Parts must have draft angles (slight taper) to allow easy removal from the mold.
Ribs and Bosses: Ribs should be designed to avoid thick areas where cooling can be uneven. Bosses should be designed to accommodate fasteners if needed.
Undercuts: Design parts without undercuts, or use collapsible cores to prevent complications in the mold design.
Surface Finish: Desired surface finish affects the molding and post-processing requirements.
Pressure die casting is a relatively fast process. The cycle time can range from 15 to 60 seconds per part, depending on the size and complexity. Larger parts will take longer, while smaller, less complex parts can be cast more quickly.
While pressure die casting is typically more cost-effective for high-volume production due to the cost of molds, it can be used for low-volume production when the initial cost is justified by the need for high precision or when there are future plans for larger production runs. Prototype production or limited batches are often feasible.
Yes, pressure die casting is capable of producing intricate and detailed designs, especially with materials like zinc, which can flow well into small cavities. However, the design needs to be optimized for manufacturability, and the complexity of the design may increase the cost due to the need for more advanced tooling and additional post-processing steps.
