Polymer fusion is a concept which has been in existent for quite a long time. As needs evolve, so has techniques improved from simple use of friction to laser plastic welding. Currently, heating results from three main sources namely friction, radiation, and actual heating. From these, five techniques of soldering exist. These are ultrasonic, friction, high frequency, radiation-based, as well as, metal plate fusion. Each differs with the other in terms of usage, advantages, and disadvantages. Below sections elaborate each.
The first technology is the radiation based fusion. Radiation bonding is a very popular technology for complicated designs which may require a three-dimensional fusion. Rays are passed on a transmissive layer which lies on the upper conducting part to lower contacts. Heat is generated in that process. Once contact surfaces are molten, clamping is automatic. Briefly, the radiation-based fusion is flexible, allow effective process monitoring and is affordable. In terms of flexibility, three and two-dimensional soldering is possible. Processes are censored through online techniques for better quality. Once acquired, the maintenance cost is affordable.
Radiation joining also has several downfalls. Unlike conventional machines, these are sophisticated hence require an expert to operate. Similarly, it may be selective on types of polymers that can be joined. As said, there has to be a good conductor and absorber. Without an experienced team to handle sorting, fusion may be impossible. Amount of money needed to procure equipment at first is super expensive.
Alternatively, joining can be obtained through friction. In the ultrasonic method, specific elements oscillate round partner surfaces. Friction created produces sufficient hotness to melt joining elements. Once molten, these parts require some compression for joining to happen. Compared to radiation equipment, this method is cheaper to purchase and handle machines for ultrasonic soldering. Additionally, low maintenance is required to keep machine operational.
One disadvantage of ultrasonic joining is flush generated as well as small particles which look like dust. If an individual is exposed to these for long, their health is affected. Unlike ray based soldering, very wide ultrasonic can only work in two dimensions. Additionally, the resultant weld line is wide with some instances having up to 10 mm spacing.
A third technique is the use of hot-plate. Joining parts of partners are placed on top and bottom of a heated metallic component so that opposite sides that are to be fused melt. Once they become molten enough, the plate is removed and surfaces joined immediately. The equipment needed are compressors and the metal plate which makes this technique inexpensive. Additionally, it is suitable for small devices which require hand-holding. However, it works with two-dimensional designs only.
In high-frequency bonding, an electric field flashing with high bandwidth moves molecules on polar ends in a circular manner. Consequently, heat is generated to melt partner points for easy bonding. Particularly, heat affects joints to be bonded only which reduces the possibility of destruction of other parts.
Friction based soldering utilizes a similar concept as ultrasonic joining. However, parts are rub against each other to produce heat. It is inexpensive and requires little capital for maintenance. Used mainly on polymers that require continuous soldering.
