Plastic Hot Plate Welding VS Infrared Welding

Hot plate welding and infrared welding belong to two different processes of plastic welding. In hot plate welding, the heating plate is in contact with the part; in infrared welding, the infrared heat source is not in contact with the part. Both plastic welding technologies have recently gained tremendous development and are becoming more and more popular. Through the servo drive, the mold position, speed, force and acceleration are accurately controlled, and the process control and data acquisition functions are strengthened. In addition, the variety of equipment models provides engineers with more choices. Infrared welding uses non-contact heating to solve a major challenge of hot plate welding, which is to avoid plastic or glass fiber sticking to the surface of the heating plate. Of course, the two welding processes have their own advantages and disadvantages. Both processes are typically used for products that require high strength or high sealing properties, and are suitable for welding large, complex geometric parts, especially cavity products, such as water tanks.

How to maintain and repair the ultrasonic welding machine in daily use?

As we all know, mechanical equipment needs maintenance to be better used to achieve a longer service life. If the machine is not maintained, various difficulties and other diseases will occur and affect your work efficiency. As a machine equipment, how to maintain the ultrasonic welding machine and make it work better? Ultrasonic welding machine maintenance common sense: 1. When cleaning the side plates and surfaces of the ultrasonic welding machine, it is strictly forbidden to use various solvents. A neutral detergent should be used and gently rubbed for testing. 2. The water accumulated in the air filter of the ultrasonic welding machine should be discharged in time before it overflows. 3. Always check whether the no-load current is the smallest, or whether the frequency is biased (for example, for our constant-rise special equipment, the frequency setting range is between 0-0.1, please press the sound wave test button, if it is within the normal range, you need Find out the cause of the problem.) It is easy to break the mold and check whether the transducer is normal.

Innovation of welding and polishing process of sheet metal door box body!

Let us first analyze the current domestic sheet metal factory welding door box products: Poor product accuracy and consistency. Domestic sheet metal factory in the stamping, bending and other pre-process basically use good equipment, but in the turnover of these no welding of the workpiece and the workpiece produced more or less deformation, in the manual welding door or the four corners of the box often do not use the fixture to locate the workpiece, but with the manual positioning of the workpiece, manual welding. As a result, even in the case where no accuracy error occurs in the previous process, errors and distortion occur in the welding process, thereby lowering the accuracy and consistency of the product. In addition, the welding quality of manual welding varies from person to person, and the consistency of welding quality is poor. Skilled welders are highly skilled and difficult to manage. The wages of welding workers in China are rising day by day, especially the high wages of skilled welding workers, difficult to recruit, difficult to retain people in enterprises, and difficult to manage. The quality of manual welding is unstable and the size of welding scar is inconsistent, which leads to the increase of subsequent grinding workload. Some door panels and box products require no internal welding scar and welding slag after welding. Manual welding is also difficult to guarantee without a fixture. The welding slag or scar produced by the welding seam in the box body is more difficult to deal. At present, the domestic sheet metal industry does not have a good welding mechanization and automation program. The characteristics of sheet metal production with many varieties and few batches limit the application of welding mechanization and automation.

Ultrasonic mold design method and amplitude parameters

Ultrasonic mold design method, mold amplitude parameter design: amplitude is a key parameter for the material to be welded. Due to the different transducers selected, the amplitude of the transducer output is different. After adapting the horn and welding head with different variable ratios, the working amplitude of the welding head can be twisted to meet the requirements. Usually the output amplitude of the transducer is 10-20μm, and the working amplitude is generally about 30μm. The ratio of the horn and the welding head is related to the shape of the horn and the welding head, the front and back area ratio and other factors. The shape is such as exponential amplitude, functional amplitude, stepped amplitude, etc. It is equivalent to the temperature of ferrochrome. If the temperature is not reached, it will not be welded. If the temperature is too high, the raw materials will burn or lead to structural damage and poor strength. It has a great influence on the transformation ratio, and the front and back area ratio is proportional to the total transformation ratio. If different welding machines are selected, the simple method is to make the welding head according to the proportion size of the working welding head, which can ensure the stability of the amplitude parameters.

What are the debugging methods of ultrasonic mold levelness?

First of all, we need to know that the ultrasonic plastic welding machine and ultrasonic mold with a good, so that the effect of welding plastic products out of the standard is closely related. Ultrasonic plastic welding machine in welding plastic parts, it is necessary to keep the ultrasonic mold and plastic parts closely, otherwise there will be leakage welding, it is difficult to achieve the effect of water airtight. Adjusting ultrasonic mold is the knowledge that ultrasonic welding machine manufacturers must learn to train their customers to operate ultrasonic plastic welding machines. What are the methods of ultrasonic mold level adjustment? Please see the following details: 1. After the ultrasonic welding head is completely sealed with the workpiece, evenly screw on a plane adjustment screw to make it symmetrical and tighten it again, and lock the base. When the direction of the ultrasonic mold is not consistent with the direction of the base, there is no way to weld plastic products. The direction of the ultrasonic welding head must be adjusted to be completely consistent with the direction of the base. 2. Loosen the horizontal adjustment nut of the flange of the ultrasonic transducer, rotate the lifting hand wheel of the fuselage, so that the ultrasonic welding head is pressurized on the workpiece, and tap the periphery of the ultrasonic welding head to be more closely connected with the workpiece. 3. Adjust the position of the middle body seat to keep a slight distance from the processed object when the ultrasonic welding head is lowered. 4. Rotate the ultrasonic welding head in the same direction as the base. After the direction adjustment is completed, the ultrasonic welding head will remain in a lowered state, and then adjust the level of the ultrasonic welding head. 5. Put the plastic products to be welded on the base, make it kiss with the base, and relax the four plane adjustment screws.

The development trend of ultrasonic equipment industry is very rapid

At present, from the perspective of the application demand of ultrasonic equipment and the market competition of ultrasonic equipment, the development speed of the ultrasonic industry is advancing with each passing day, and the development trend is very rapid. At the same time, many colleagues in the same industry and various ultrasonic equipment manufacturers are all Seeing new opportunities, but in the end, can we seize the opportunities, stand firm in the market, and stand firm in the pace of enterprise development while seeing the opportunities? is the top priority. At present, we can clearly see the rapid development of the intelligent field and the proportion of the electronic industry in the market. We should know that the electronic industry is the largest field of demand for ultrasonic welding. In order to better support the market demand, our equipment technology must be improved to better serve the market and seize the opportunities that belong to our industry. To improve one's own equipment technology, it must be reflected in two points. One is to highly develop independent research and development technology, and the other is to introduce foreign advanced technology, but it must not be blind. It is necessary to understand that technology lies in precision, and blindly invest in research and development, resulting in technology research and development. Complicated, perhaps some companies will think that the more technology, the richer the better, the more comprehensive technology, the multi-faceted technology, represents complete, in fact, this often leads to waste of R & D investment. The R & D of ultrasonic welding technology must be considered from the market demand. It should be understood that the industry equipment exists because of the market demand. If the demand does not exist, the significance of its existence will be lost.
