Solvent Bonding
Did you know?
Solvent bonding is commonly used to weld amorphous thermoplastics.
The solvent melts the mating surfaces and creates a chemical
bond between the two parts.
How does it work?
Material selection is important when using solvents. Tongue
and groove assemblies that allow a channel for the solvent
can provide a clean, strong weld that also allows for part
location. Solvents can be applied manually or semi-automatically
and will “wick” into surfaces. Care must be taken
not to over-apply solvents.
Key Factors:
A well-ventilated area is required when working with solvents.
Also ensure solvents are stored properly. Key pros and cons
are:
| 1. Pros: |
|
|
| |
a. Good clean bond
b. Possible to achieve hermetic seal
c. Distributes load over bond area |
|
| 2. Cons: |
|
|
| |
a. Requires good joint design
– may not be suitable for small parts
b. Vapours
c. Only good for amorphous materials
d. Parts cannot be disassembled. |
