Helium test machine

Helium Leak Detector

A Helium Leak Detector (Helium test machine) is designed for test on evaporator, condenser and their connecting pipes so as to ensure that the leakage rate of all products can meet a certain standard.
Designed for different applications, the test method could be either vacuum box type or hose assembly clam shell type. Most machines for automotive heat exchanger application are vacuum box type. This design permits to test several work pieces in a same box, or in case of changing models frequently.

Helium leakage test machine is widely equipped in automotive industry for testing on piping, air-conditioning system, compressor, valve, wheel and oil cooler etc.

Specifications

Main Technical Parameters

Helium Leak table

Features:
– Fixtures match to work pieces, system identifies work piece by the fixture

- Passed work piece label auto-printed, test data auto-stored

- 30 groups programs fulfill various types test requirements

- Highly automatic operation

- High test precision and efficiency

Description

Auto Feeding Machine

The numeric auto feeding machine is designed to cooperate a normal punching machine, through which the normal punching would be upgraded into an automatic numeric punching machine.
This could enable:
– Feed with a whole plate
– Automatic material arrangement
– Automatic feeding
– Automatic punching
– Utilize the raw material to the maximum
– Ensure the safety of operators
Under condition of 1mm plate and 200mm pace, the automatic feeding accuracy can be about 0.15mm!
The automatic feeding machine could be delivered either alone to upgrade your existing punching machine or together with our punching machine.

Ultrasonic Cleaning Machine

Ultrasonic Cleaning Machine

In order to ensure a good brazing effect, most punched parts of automotive heat exchangers need be cleaned to remove the residual oil and grease by ultrasonic process with a special cleaning detergent used. It should be pointed out that the ultrasonic process and cleaning detergent we use differ from the conventional ones.
The ultrasonic cleaning process and detergent we use have been widely used by rocket making industry, nuclear power stations, auto companies, optics and semiconductor companies, refrigerator companies, electro-mechanical companies, wire drawing and part punching industries.

Advantages of our cleaning process and detergent:

- Fully automatic cleaning and high efficiency

- Stable and continuous caterpillar transmission

- Cleaning under room temperature, which greatly saves energy

- Water-soluble detergent, easily handling and environment friendly

- Fully automotive multiple security devices
