Automotive dispensing solutions: engine cylinder head and radiator seal dispensing?
Sealing the engine cylinder head and radiator is a critical process in the automotive and industrial engine sectors, and dispensing technology plays a vital role.
Below, I will elaborate on the specific applications, technical requirements, and development trends of dispensing technology for these two components.
2. Radiator Sealing Applications
The core of radiator sealing (including the main radiator, intercooler, and oil cooler) lies in the connection between the core and the water chamber, as well as the sealing of pipe joints and other parts.
a. Sealing the Core and Plastic Water Chamber
This is the most critical sealing step in radiator manufacturing.
● Application Area: The interface between the aluminum or copper radiator core and the nylon or plastic upper and lower water chambers.
● Adhesive Type:
One- or two-component epoxy resin adhesive: Offers extremely high bond strength and durability, capable of withstanding the pressure, vibration, and thermal shock of the cooling system. This is currently the most mainstream technology.
● Key Glue Dispensing Techniques:
High Cleanliness Requirements: Before dispensing, the interface between the core and water chamber must be rigorously cleaned and treated (such as plasma treatment) to ensure proper adhesive penetration and bonding.
Complex Path Tracking: The robot must accurately track the complex two-dimensional or three-dimensional path of the water chamber flange to ensure a continuous and uniform glue line.
Pressing and Curing: After dispensing, the water chamber and core are immediately pressed together and cured in a drying oven or natural methods. The accuracy of dispensing directly determines whether there is any risk of glue overflow or glue shortage after pressing.
