Sales and quality go hand in hand, machine knowledge sharing

Finally, when the flowers bloom again, we are full of enthusiasm and hope, responsible and serious attitude to greet each new beginning, we firmly believe that good things will happen.  

At the beginning of the new year, we have had a very good omen - domestic and foreign customers have placed orders, the machine is also in production, the old customers take the initiative to introduce us to new customers, both domestic and foreign customers are very good comments on our machine... In fact, these are not worth mentioning at all, because quality is the life of the machine, the quality is not good, the life of the machine is also coming to an end, as a business peddling low quality products, cheating customers and cheaters?  

In order to thank the new and old customers for their love and trust of our products, here I will analyze and elaborate the application of various types of machines, characteristics and problems in the actual application of the machine.

Our products can be divided into ordinary wrapping machine, online wrapping machine, horizontal wrapping machine, rotary arm wrapping machine, Top sheeter wrapping machine 5 categories, which ordinary wrapping machine products meet the requirements of automation is not high, non-streamline most factories and enterprises, such as: wood, glass, hardware, beverage industry…..Not only flexible and durable, high efficiency, cost saving, but also according to the actual need to increase the top pressing, weighing, forklift groove and other devices to meet customer needs. Online wrapping machine is to cooperate with the production line, complete multi-task, streamline operation, its high efficiency in the industry has been widely used in electronics, chemical industry and other industries. Horizontal wrapping machine is suitable for long strip, tube and other articles, with the function of packaging and binding, to meet the needs of various products. Suitable for steel, profile and building materials market. The most significant feature of rocker arm winding packaging machine is high efficiency, can be said to be very high, for the efficient requirements of buyers, this model is the most appropriate. Film-coated winding packaging machine is a packaging model that can pack five sides of goods. For easy moisture, or products that need to pack five sides of goods, this model is undoubtedly the best product.

To the new customers to speak so much of course will not forget the needs of our old customers, you have questions, we will help you answer immediately!  

Here's a question that will strongly involve expertise  

Question: Why does the film break when the stretching ratio of the stretch film is "greater" than the pre-stretching ratio of the wrapping machine?  

If the stretch ratio of the film is 1:4, The stretching ratio of the device is 1:2.5  

The residual tensile ratio was 1.5 times;150%  

The film out induction marked '3' refers to the setting of tension  

The higher the tension, the more flexible the film induction  

But the remaining stretch ratio is 150%; The film marked '5' has a very low tightness in the package of goods  

At this time only by adjusting the tension to improve the degree of tightness; In this way, the film induction can be touched and then the membrane output  

However, the general tensile length of the film is relatively high belongs to the soft film.  

When the tension/resistance stretches the film to its limit, the thickness of the film is only 3 microns to 5 microns. If it happens to be around the corner at this time; the film breaks when it touches the edges and corners  

The true principle of pre-stretching is as follows. We can compare the total pre-stretching to 100% : 
  

"Primary stretching (equipment stretching 90%) + secondary stretching (tension + 10% stretching generated by RPM) = correct stretching setting"
