Die-Casting Machine Connector is a important application in the die casting process, mainly for the transmission of force and motion.
Depending on the design and needs, the connector can be available in a variety of materials and construction forms to meet specific functional requirements.
Haichen’s die casting machine connectors are typically made of aluminum alloys (such as ADC12, A380, etc.), zinc alloy, magnesium alloy, and other materials.
And are manufactured through the die casting process, offering high mechanical properties, corrosion resistance, and high precision.
Performance Requirements for Die-casting Machine Connectors
- High-Temperature Resistance
- Pressure Resistance
- Sealing Performance
- Materials and Coatings
High-Temperature Resistance
Die-casting machines usually operate in high-temperature and high-pressure environments, so connectors must have excellent high-temperature resistance.
For example, the temperature range of Haichen Die-casting Machine High-Temperature and High-Pressure Connectors can reach -55℃ to +200℃, and they can run stably at 200℃ for 600 hours.

In addition, accessories such as rubber joints must also have high-temperature resistance to ensure they do not deform or crack in high-temperature environments.
Besides, the die-casting machine connectors themselves have good high-temperature resistance—manufacturers mostly make them from aluminum alloys, zinc alloys, copper alloys and other materials that suit high-pressure and high-temperature industrial settings.
Pressure Resistance
Die-casting machines withstand extremely high pressure during operation, so connectors must have excellent pressure resistance capabilities.
For example, Haichen’s series of die-casting machines can reach an operating pressure of 140 MPa and run stably at 140 MPa and 200℃ for 10 hours.

In addition, high-pressure connectors must maintain stable mechanical properties under high-pressure conditions.
Such as tensile strength, flexural strength and flexural modulus, to ensure stability in complex application scenarios.
Sealing Performance
Sealing performance counts as one of the key performance indicators for die-casting machine connectors.
Accessories such as rubber joints must have excellent sealing performance to prevent hydraulic oil leakage, reduce the impact of internal air or moisture on equipment operation, and thereby improve the overall efficiency of the equipment.
In addition, high-pressure connectors must maintain reliable sealing performance under high-pressure conditions to ensure their dependability in complex application scenarios.
Materials and Coatings
The performance of die-casting machine connectors is also closely related to their materials and coatings.
For example, the reliability of crimp connectors in high-temperature environments depends on their materials and coatings.
Selecting high-temperature resistant materials such as nickel and copper alloys, and matching them with protective coatings or insulating layers, ensures their performance.
In addition, the current-carrying capacity of welded connections changes slightly in high-temperature environments.
While that of crimped connections drops sharply under high temperatures, which shows that welded connections have greater advantages in high-temperature settings.

Reliability and Stability
The reliability of die-casting machine connectors under high-pressure and high-temperature conditions depends on their design, materials and manufacturing processes.
For example, Haichen High-Pressure/High-Temperature Connectors are specifically designed for harsh environments and can deliver excellent performance and reliability under high-pressure and high-temperature conditions.
In addition, manufacturers need to optimize the manufacturing and design of die-casting machine connectors through CAD/CAE and finite element analysis technologies to ensure their performance and reliability.
Parts or Components of Die Casting Machines and Their Uses
HAICHEN die casting machines are complex machines used to manufacture metal parts with high accuracy and consistency.
Some of the main parts of a die casting machine include:
- Die/Mold
- Injection System
- Clamping Unit
- Hydraulic System
- Ejector System
- Control System
- Cooling System
- Lubrication System
- Safety System
Die/Mold
The die is the tool used to shape the metal into the desired form. It consists of two parts, the fixed die half and the movable die half.

Injection System
The injection system includes the shot sleeve, plunger, and gooseneck. The molten metal is injected into the die cavity through the injection system.

Clamping Unit
The clamping unit is responsible for holding the die in place during the casting process. It consists of the stationary platen, movable platen, tie bars, and toggle mechanism.

Hydraulic System
The hydraulic system provides the power to move the various components of the machine, such as the injection system, clamping unit, and ejector system.

Ejector System
The ejector system is responsible for ejecting the casting from the die cavity once the casting has solidified. It includes ejector pins, an ejector plate, and an ejector cylinder.

Control System
The control system manages the operation of the die casting machine. It includes the machine controller, sensors, and actuators.

Cooling System
The cooling system helps to control the temperature of the die and the casting during the casting process. It includes cooling channels in the die and a water cooling system for the machine.

Lubrication System
The lubrication system is responsible for lubricating the various moving parts of the die casting machine to reduce friction and prevent wear and tear.

Safety System
The safety system includes various safety features to protect the operator and the machine from accidents. It includes safety guards, emergency stop buttons, and safety interlocks.

Material selection
Connecting rods often need to be high strength and abrasion resistant to withstand the high loads and wear of the die casting process.
For example, the connecting rod material of the mechanical structure uses carbon steel (such as S45C) or more to avoid wear or deformation due to insufficient strength.
In addition, die-cast zinc-based or aluminum-based alloys are suitable for different application scenarios.

Structural design
The design of the connecting rod needs to consider its specific role in the die-casting machine.
For example, in the floating piston connection structure of the die-casting machine.
The connecting rod and pressurized piston rod are a single unit.
The O-ring on the connector is eliminated to improve the stability of the oil pressure.
In addition, auxiliary support rods and V-shaped support frames, enhance their strength and prevent deformation.

Functional Applications
Compared to traditional steel linkages, Haichen‘s aluminum connecting rods are lighter and are especially suitable for areas where weight is high, such as racing cars and motorcycles.
Aluminum itself has good thermal conductivity, which helps to dissipate heat better in high-temperature engine systems.
Additionally, aluminum is more suitable for CNC machining and can be designed into connecting rods with various complex structures to suit different application needs.

Innovative design
With the development of technology, the design of connecting rods is also constantly innovating.
For example, in a die-casting device for low-pressure casting casings.
The connecting rod achieves high-frequency intermittent traction through a servo-motor traction system.
And the pitch is adjusted according to the diameter of the casting rod to ensure stable operation.
