Aluminum castings for automotive manifolds

2024-08-17

Our automotive manifold aluminum castings are made of high-precision aluminum alloy material through fine casting process, which has excellent high temperature resistance, corrosion resistance and good mechanical properties. This product is widely used in the intake and exhaust manifolds of automobile engine systems, which can effectively improve the overall performance and service life of the engine. The lightweight design of aluminum castings not only reduces the weight of the whole vehicle and improves fuel efficiency, but also has high fatigue and wear resistance. Through strict quality control and multiple testing procedures, we ensure the stability and consistency of each product to meet the demand for high-performance and high-precision parts for various vehicle models. Whether in high temperature environment or long time operation, manifold aluminum castings can maintain excellent working performance, which is a key component in the powertrain of modern automobiles.

Difference between low pressure casting and gravity casting

2024-08-05

Low-pressure casting and gravity casting are aluminum alloy casting process, low-pressure casting is also known as anti-gravity casting, low-pressure casting. Low pressure casting is also known as anti-gravity casting, low pressure casting. The difference between it and gravity casting is mainly reflected in the following aspects. The difference between the casting principle of operation: the difference between the casting principle of operation: low pressure casting is also known as anti-gravity low pressure casting, so the name of the casting method is through the gas pressure against gravity casting molding, as shown in the figure on the right: through the sealed crucible injected into the gas (usually 0.06 ~ 0.15MPa)), the aluminum liquid in the role of pressure through the middle of the pipeline, the product for the molding of the casting, holding pressure for a certain period of time, the aluminum water cooled in the mold cavity, the aluminum water cooled in the mold cavity. Aluminum water in the mold cavity cooling molding, through the discharge of gas pressure, open the mold, remove the product. Gravity casting refers to the casting of aluminum water through the action of gravity → filling → solidification and contraction → casting, this...

Low pressure casting process

2024-08-05

Low pressure casting is a method of forming castings by filling them with liquid metal under pressure. It is called low-pressure die casting because it uses very low pressure. The process flow (see Figure 1) is: in the sealed crucible (or sealed drill), into the dry compressed air, liquid metal 2 in the gas pressure, along the ascending tube 4 rise, through the gate 5 smooth into the cavity 8, keep the crucible recreational hydraulic pressure until the casting is completely solidified, and then relieve the hydraulic pressure, so that the open tube is not solidified liquid metal flow crucible collapsed, and then open the casting through the cylinder 12. The process specification of low pressure casting includes charging, pressurizing, preheating temperature, injection temperature, casting coating, etc. (1) Charging and pressurizing Lifting pressure refers to the pressure required when the level of the metal liquid rises to the mouth of the stream. The rise of the metal liquid in the ascending tube should be as slow as possible, in favor of the cavity gas...
