People Also Ask
Q: What products can your radiator core builder machine produce？
A: Our assembly machine can produce radiators, condensers, and intercoolers. We can customize the machine according to your needs.
Q: What is the maximum size of the radiator produced by your assembly machine？
A: Our maximum assembly size is L1800 * W1200 * T56mm. However, we can customize the machine according to your size.
Q:Can fins of different heights be assembled on the same radiator core builder machine?
A: The core machine can only assemble cores with a single fin height. We must customize fins of different heights if you need to assemble them.
Q: Is it possible to assemble fins of the same height in the radiator core and condenser core on the same radiator core builder machine?
A: No, because the radiator and condenser pipes are very different and cannot be mixed.
Q: Can the same radiator fin-forming machine produce different fin models?
A: The fin-forming roller is changeable, and different fin models can be produced on the same machine.
Q: What is the size of the fins produced by the radiator fin-forming machine?
A: Fin thickness: 0.07-0.08mm; fin width: 8-200mm; we can customize the machine according to size.
Q: What metal materials can the heat sink forming machine process?
A: Aluminum foil material: 3003-H16, Copper material: H62.
Q: How many types of radiator plastic tank crimping machines are there?
A:Our company supplies manual plastic tank crimping machines, semi-automatic pneumatic and servo-type plastic tank clinching machines, hydraulic and pneumatic-type plastic tank crimping machines, and fully automatic plastic tank clinching machines. We can customize the machines according to your needs.
Q: Which one is better, an automatic crimping machine or a semi-automatic crimping machine?
A: An automatic crimping machine is suitable for a single model order of 300 sets or more at a time. It is ideal for this production plan, as it has more models but less quantity.
Q: How many model types can an automatic radiator plastic tank crimping machine system store?
A: Because it is a PLC interface setting, it can store about 200 different tank models and positions and covers most car models.
Q: What is the maximum size of the radiator produced by your plastic tank crimping machine？
A: The maximum workpiece size we produce is L1000*W900mm, and we can customize the machine according to your size.
