In some cases, the hot plate welding process is usually considered. The following are some factors that make hot plate welding superior to other methods:
1.Large components: This factor may rule out ultrasonic welding.
2.The product geometry is complex: Complexity may hinder the use of vibration welding.
3.Excessive or loose particles (burrs) are unacceptable.
4.No marking is allowed on the A-face part.
5.Assembly requires high strength and airtightness
6.Assembly/machine cycle times within the range of 15 to 25 seconds are acceptable.
In addition to these common reasons, there are some other factors that need to be considered:
1.Small components: Hot plate welding is not only applicable to large parts. Leading manufacturers offer models specifically designed for parts no larger than 6 inches square.
2.Components with simple geometric shapes: These components can also benefit from the low-stress and high-strength effect of hot plate welding.
3.Flying edge control: Even if flying edge control is not the top priority, who wouldn't like it?
4.Part marking: This is usually an unexpected side effect caused by energy misguidance. It may lead to component scrapping due to inconsistent welding results.
5.Stable processing window: The performance of the hot plate welding process is usually very stable, which is conducive to improving operational efficiency.
6.Welding speed: If the hot plate welding cycle time is not fast enough, it is advisable to consider welding multiple components simultaneously.
Three. Advantages and Disadvantages of Hot Plate Welding
Advantages:
High welding strength;
It can be airtight welded with reliable strength.
The shape design of the welding part of plastic products is relatively simple.
Disadvantage:
The heat generated by the hot plate softens the plastic products, and the cycle is relatively long.
The plastic adhered to the hot plate will show a stringing phenomenon (anti-sticking treatment can be done).
When plastic products of different materials are welded, the strength may be insufficient.
