Product Description

Product Description

                                Haichen plunger rod in die casting machine 

A plunger rod is an essential component of the injection system in die casting. Its primary function is to push molten metal into the die cavity under high pressure.

 

 

Product Parameters

 

 

 

Plunger rods are usually made of steel, such as H13 or 45# steel, and are heat-treated and surface-treated to increase durability.

Forcing Molten Metal into the Die Cavity

• Mechanism: In die casting, the plunger rod is positioned above the gooseneck or shot chamber, which contains the molten metal. When the plunger rod moves downward, it displaces the molten metal and forces it through the nozzle and into the die cavity at high speed.
• Importance: This rapid injection of molten metal ensures that the metal fills the die cavity quickly and completely. It minimizes the risk of defects such as porosity or incomplete filling.

Controlling Metal Flow

• Speed and Pressure: The plunger rod can be designed to control the speed and pressure of the metal flow. By adjusting the speed of the plunger rod's movement. The rate at which the molten metal is injected into the die can be controlled. This is critical for ensuring proper filling of the die cavity and for preventing defects such as cold shuts or turbulence.
• Consistency: The plunger rod helps maintain a consistent flow of molten metal, which is essential for producing high-quality castings with uniform dimensions and properties.

Ensuring Proper Die Filling

• Complete Filling: The plunger rod ensures that the entire die cavity is filled with molten metal. This is particularly important for complex parts with thin walls or intricate geometries, where incomplete filling can lead to scrap parts.
• Minimizing Defects: By ensuring that the die cavity is filled quickly and completely, the plunger rod helps minimize defects such as shrinkage, porosity, and gas entrapment. These defects can weaken the final product and affect its performance.

 Mechanical and Thermal Resistance

• Durability: High temperatures and pressures act on the plunger rod during the die casting process. The plunger rod material must withstand these conditions without deforming or wearing out quickly.
• Material Selection: High-strength steel or specialized alloys resistant to thermal and mechanical stresses are common choices for the plunger rod. This ensures that it can operate reliably over a long period of time.

Sealing and Isolation

• Preventing Backflow: The plunger rod helps prevent molten metal from flowing back into the shot chamber once it has been injected into the die cavity. This is important for maintaining the proper volume of metal in the die and for ensuring consistent part quality.
• Isolation: In some designs, the plunger rod also helps isolate the molten metal in the shot chamber from the rest of the machine, preventing contamination and ensuring a clean injection process.
