Product appearance stick protective film or ultrasonic welding pad protective film. Every customer are great differences of ultrasonic welding requirements, some products are not surface appearance, ultrasonic welding it tightly, do not need ultrasonic cutting machine to pay attention to appearance. But in most cases ultrasonic welding requirements of the products is relatively high, such as U disk, mobile phone batteries, SD card, mouse receiver, etc. How to deal with product appearance bruised and scratched problem has always been plagued by ultrasonic welding machine equipment engineer, to deal with the problem of demand, such as ultrasonic mould do fitted to the product, ultrasonic mould whether smooth, etc.
Adjust the ultrasonic welding. The length of the ultrasonic welding time directly affects the quality of products by ultrasonic welding, time is too long will be embossed product appearance, can appear time too short welding, cold joint, easy to fall off wait for a phenomenon. As long as the basis for detailed product demand to adjust to the appropriate moment is good choose.
Product positioning mechanism. When planning a ultrasonic generator driver ultrasonic welding plastic product requirements according to product planning and good product features and plastic registration agencies can not happen when ultrasonic welding dislocation phenomenon.
Adjust downward pressure, downward pressure with plastic products ultrasonic welding effect is very big, in general plastic products by ultrasonic vibration conflict quantity of heat, so as to achieve the welding effect. Not by pressure welding effect, just have the effect. So the size of the pressure is very crucial, must pay attention to!
But in the use of ultrasonic welding machine equipment, ultrasonic metal welding some aspects of the demand for the cause of the production department notice, otherwise may make ultrasonic welding bad product, lead to rejection rate rise.
Ultrasonic welding of bad refers to:
1. The plastic cover up and down without full welding, lead to false welding, welding not firm, etc.;
2. Be welding appearance surface scratches, damaged pieces of plastic, etc.;
3. The plastic top and bottom cover dislocation, etc.
