Common problems and solutions for vacuum formed products

Various problems may occur during the production process of vacuum formed products, including quality issues such as "crystal dots, bubbles, uneven thickness, scratches, pulling, inadequate suction, and bursting".
1. Crystal dot and bubble problems: Crystal dot and bubble problems are the most common issues in vacuum forming plants, which mainly depend on customer requirements.
The reasons for the above problems are:
(1) Is the quality of the raw material brand new;
(2) Whether the mold made is a copper mold, an aluminum mold, or a gypsum mold depends on the mold making itself;
(3) Whether there is dust in the production environment, whether it is a dust-free workshop, whether the machine surroundings are clean, and so on.
2. Uneven thickness: The problem of uneven thickness mainly depends on the temperature control system of the vacuum forming equipment, which is the main cause of uneven thickness. Secondly, it is closely related to the quality and thickness of the raw materials, which is closely related to the products produced. In addition, whether the upper mold is made standard, and so on.
3. Scratch problem: Scratch problems are related to many factors, from the raw materials themselves to machine operations, passing through machines, punching machines, folding, packaging, etc. This phenomenon may occur mainly based on customer requirements. If customers are very concerned about this issue, we must pay special attention to taking preventive measures during the production process.
4. Cable pulling problem: There are two main phenomena for cable pulling problems: one is that the material is too cooked, and the other is that the upper molding is not good. Both of these situations are caused by the production process, and the captain should pay attention to adjusting to avoid them.
5. The problem of inadequate suction: The main reasons for inadequate suction are due to insufficient product temperature, as well as the product being too deep and not being pressed onto the mold or not being pressed onto the mold properly. This phenomenon is mainly achieved by adjusting the machine by the captain.
6. Explosion problem: The explosion problem is mainly determined by the properties of the material itself. Some materials are very brittle and easy to explode during the production process. In addition, when producing APET materials, the silicone oil in the material is not enough, which can cause explosion. It is also related to weather. In winter, materials are relatively brittle, so special attention should be paid to the raw material formula. Finally, there may be problems with the cutting die or improper adjustment of the cutting tool during punching.
