The knowledge of zipper machinery is a must for beginners
The working principle of the zipper machine is similar to that of a syringe for injection. It uses the thrust of the screw (or plunger) to inject the plasticized plastic in the molten state (that is, the viscous state) into the closed mold cavity. Inside, the process of obtaining the product after the curing and shaping process inside the zipper machine. This knowledge of zipper machinery must be learned by Xiaobai.
At the same time, due to the high injection pressure, a correspondingly high pressure is generated in the mold cavity (the average pressure in the mold cavity is generally between 20-45MPa), so There must be sufficient clamping force. It can be seen that the injection device and the clamping device are the key components of the injection molding machine.
There are three main aspects to the evaluation of plastic products, the first is the appearance quality, including integrity, color, gloss, etc.; the second is the accuracy of size and relative position ; The third is the physical properties, chemical properties, electrical properties, etc. corresponding to the use. These quality requirements are also different according to the different occasions where the products are used.
The defects of the products mainly lie in the design of the mold, the manufacturing precision and the degree of wear. But in fact, technicians in plastic processing plants often suffer from the difficult situation of using technological means to make up for the problems caused by mold defects and have little effect.
The adjustment of the process in the production process is a necessary way to improve the quality and output of the product. Since the injection molding cycle itself is very short, if the process conditions are not well mastered, there will be an endless stream of waste products. When adjusting the process, it is best to change only one condition at a time, and observe it several times. If the pressure, temperature and time are all adjusted together, it is easy to cause confusion and misunderstanding, and there is no reason for the problem.
There are many ways to adjust the process. For example, there are more than ten possible solutions to solve the problem of dissatisfaction with products. Only by choosing one or two main solutions to solve the crux of the problem can the problem be truly solved. In addition, attention should be paid to the dialectical relationship in the solution. For example, if the product is dented, sometimes the material temperature should be increased, and sometimes the material temperature should be reduced; sometimes the material quantity should be increased, and sometimes the material quantity should be reduced. Recognize the feasibility of reverse measures to solve the problem.
The above is the necessary knowledge for beginners of zipper machinery, I hope it will help you. In addition, the molding process of the general screw zipper machine is as follows: first, the granular or powdery plastic is added to the barrel, and the plastic is melted by the rotation of the screw and the heating of the outer wall of the barrel.
