The Semi Automatic Radiator Tank Crimping Machine is designed for assembling and repairing passenger car radiators by crimping plastic tanks, gaskets, and radiator cores together with controlled pneumatic pressure.

It is widely used in radiator repair workshops and flexible production lines where consistent sealing quality is required but full automation is not necessary. The machine helps stabilize the crimping process and reduces assembly variation caused by manual operation.

Pneumatic crimping system with stable pressure control

This machine is commonly applied in:

• Passenger car radiator repair and reconditioning
• Radiator tank replacement and reassembly
• Small and medium batch radiator production
• Flexible automotive radiator assembly lines

It is particularly suitable for workshops handling multiple radiator models, where quick adjustment and reliable sealing performance are required.

The operator positions the radiator core, gasket, and plastic tank into the fixture. The pneumatic system then applies controlled pressure to complete the crimping process.

Compared with fully manual methods, this process ensures more uniform force distribution, helping improve sealing stability and reduce the risk of coolant leakage caused by uneven compression.

• Stable pneumatic pressure ensures consistent crimping quality
• Flexible semi-automatic design suitable for different radiator models
• Reduces dependency on operator experience
• Improves sealing reliability and reduces leakage risk
• Suitable for repair workshops and low-to-medium volume production

In radiator assembly and repair, the sealing between the tank and core is a critical point that directly affects product performance.

Manual crimping often leads to inconsistent pressure distribution, which can cause uneven sealing or long-term leakage issues. This machine helps standardize the crimping process, making the output more stable even in non-automated production environments.

Q1: Is this machine fully automatic?
No. It is a semi-automatic machine. The operator loads the radiator, and the machine performs the crimping process.

Q2: What is it mainly used for?
It is used for radiator tank crimping during repair, reassembly, and small-scale production.

Q3: Can it handle different radiator sizes?
Yes. It supports a wide range of passenger car radiator sizes within the specified parameters.

Q4: What is the main advantage over manual crimping?
It provides stable pneumatic pressure, improving sealing consistency and reducing leakage risks.

Q5: Is it suitable for factory production?
Yes, especially for flexible production lines and mixed-model radiator assembly environments.
