Cooling system. The basically formed plastic product with a certain temperature is cooled to below the thermal deformation temperature, and the product is cooled and solidified. After being removed from the mold by the demolding device, the size is fixed and the product does not deform.

The basic process of thermoforming is: sheet clamping → heating → forming → cooling → demolding. Among them, molding is the most important and complicated. Most of the thermoforming is carried out on a forming machine, which varies greatly depending on the thermoforming method. All kinds of molding machines do not have to complete the above five processes, and can be selected according to the actual production needs.

Usually the maximum size and maximum forming depth of the clamping device are used as the main parameters preform mold of the thermoforming machine. ① Material clamping. When the material is clamped by thermoforming, when a plastic board (sheet) cut to a certain size is used, in order to prevent thermal shrinkage and sagging of its own weight, it is a measure to clamp the board (sheet) around the material to maintain the release shape. ② Heating. The heating system heats the board (sheet) material to the temperature required for molding at a fixed time and temperature, so that the material becomes a highly elastic state, and the next molding process is smoothly performed. ③Forming.The process of plasticizing the plate (sheet) material softened by heat into the desired shape through the mold and various related devices. ④ Cooling system. The basically formed plastic product with a certain temperature is cooled to below the thermal deformation temperature, and the product is cooled and solidified. After being removed from the mold by the demolding device, the size is fixed and the product does not deform.

It is understood that the number of injection molding mold standards formulated by my country has far exceeded that of other major mold manufacturing countries in the world. But how to specifically formulate key points and strengthen work? Then let us Shenzhen mold manufacturers summarize the following three points for everyone: 　

1. With the development of mobile Internet +, big data, cloud computing technology, and intelligent manufacturing, mold companies are To accelerate the speed of transformation and upgrading, mold technology is also developing in the direction of digitization, informationization, automation, intelligence, and green manufacturing. Speed ​​up the standardization of advanced mold technology, especially some key technical fields, so that the mold standards formulated have a certain degree of advancement. Promote the industrialization, marketization and large-scale development of advanced mold technology achievements.　　

2. Improve the applicability of injection mold standards. The applicability of the standard is mainly reflected in the willingness of the mold standard user unit and the injection molding standard Plastic bottle mold / mold part manufacturing unit to adopt the standard and apply the mold standard to the actual production.　　

3. Guide groups that have standardization needs but lack a standardization work foundation to carry out standardization activities, and help groups that already have a certain standardization foundation to improve and perfect related procedural rules.
