Summary:Huaian thick sheet plastic suction refers to the processing process of using professional machinery, using thermoplastic plates as raw materials, heating to softening temperature through an oven, and then adsorbing thermoplastic plastic plates to the working surface of the plastic forming mold and cooling forming through the vacuum negative pressure between the plastic plates and the plastic forming mold.

Huaian thick sheet blister is a kind of plastic sheet processing and molding. According to many years of actual combat experience in thick blister technology, outstanding science and technology have adopted advanced equipment, and large-scale blister is at the top level in terms of molding area and molding thickness. In fact, the principle of thick plate blister is similar to the principle of thin plate blister. The positioning of the board through the oven heated to the softening state, the blister mold and its surrounding to form a closed space, the instantaneous extraction of air in the cavity, the board firmly stuck to the mold surface, cooling to obtain the product process. So, what are the advantages and disadvantages of Huaian thick sheet blister in production? Advantages: 1) The mold cost is small, the development cycle is short, and it is suitable for small production. 2) The mold can make products with different material thickness. Disadvantages: 1) The shape is limited, and only hemispherical products can be produced. 2) The dimensional accuracy of the product is worse than that of injection molding.


Huaian thick sheet blister process is what kind?


For Huaian thick sheet blister, similar to the principle of sheet blister. The positioned plate is heated to a softened state by an oven, and the blister type forms a closed space with its surroundings. The air inside the cavity is instantly extracted, and the plate is firmly adhered to the surface of the mold and cooled to obtain the product. Blister molding is a cyclic process, each cycle mainly includes feeding-heating softening-back blowing-blister-cooling shaping-alopecia drunk. After taking out the plastic parts, reposition the wooden board (which can be received or automatically) for the next cycle.


Huaian thick sheet plastic production process from the mold production and processing, first according to user requirements or sample specifications to make plastic mold. Under normal conditions, plaster is used to make blister packaging molds, but wood and metal sheet products are also used as molds.


After making the gypsum mold used in the thick sheet blister process, first completely or dry and naturally dry, and then according to the convex and concave conditions on the surface of the product, use 1-2mm drill flowers to drill a lot of holes in the low recesses that do not affect the shape of the product packaging.


For products such as packaging boxes, make a small hole around it to extract air when inhaling plastic production. After the mold is punched, the gypsum mold should be treated hard. The method of treating hard is to soak and dry with deep alum saturated solution.


Wait until the thick plastic mold is completely dry, install the mold on the upper iron plate of the vacuum chamber. Then, according to the mold size, the plastic sheet is filled into the applicable specification size. The piece is completely fixed in a heated wooden box, and then the wooden box and the plastic piece are put into a constant temperature oven for gentle treatment.


When Huaian thick sheet is used for plastic absorption, the soft plastic sheet should be placed in the vacuum chamber together with the wooden box, and the suction switch should be activated to suck the air in the vacuum chamber clean. After the plastic sheet is cooled, the same concave package or process mold as the mold can be obtained.
