What is the function of Yancheng thick sheet blister?
Time: 2021-11-23
Yancheng thick sheet blister is a key process equipment for making plastic parts through vacuum suction molding process with plastic plates as raw materials. Thermoplastic plates are used as raw materials, heated to softening temperature through an oven, and then through the vacuum negative pressure between the plastic plates and the plastic molding mold, the thermoplastic plastic plates are adsorbed to the working surface of the blister molding mold and cooled again.

What is the function of Yancheng thick sheet blister?
Thick plastic inhalers are usually composed of a plate positioning system, a plastic mold positioning system, a frame system, a heating system, a cooling system and an electrical control system.
(1) The plate positioning system is generally composed of a well-shaped steel pressure box, a power cylinder or a cylinder, and a balanced synchronization mechanism. Its function is to strengthen the position of the plastic sheet. The pressure box of the rack-type heating method is an upper and lower structure, and a side locking mechanism is added to ensure that the pressure box is tightly sealed with the wooden board pad. The frame can be adjusted according to the mold size, separated and adjusted automatically.
(2) plastic mold positioning system is generally composed of upper and lower mold, upper and lower mold cylinder or cylinder, synchronous mechanism. Its function is to strengthen the positioning of the blister mold and connect the mold to the vacuum pipe. Positioning method manual screw lock or pneumatic self-locking two methods. The synchronous mechanism can make the upper and lower molds float up and down at the same time to ensure the precision of blister molding.
(3) The frame system is generally composed of a steel frame, a sealed box and a protective door. The protection door is divided into automatic and manual distinction.
(4) The heating system is generally composed of heating bricks or heating pipes, oven body and power cylinder or motor.
(5) The cooling system is generally composed of gas, water pipes and sprinkler heads.
(6) Electrical system The electrical control system can realize the process requirements (temperature, speed, time) and various program actions of air intake together with pneumatic or hydraulic system management. It is mainly composed of PLC and touch screen, contactor, electronic components, thermostat, solenoid valve, sensor, etc. There are usually three control methods: manual, automatic and adjustment.
What is the principle of Yancheng thick sheet blister?
The principle of thick sheet blister is similar to that of thin sheet blister. The positioned plate is heated to a softened state by an oven, the blister mold and its surroundings form a closed space, the air inside the cavity is instantly extracted, the plate is firmly adhered to the surface of the mold, and the product is obtained through cooling and shaping.
Blister molding is a cyclic process, each cycle mainly includes: material-heating softening-back blowing pre-pulling-blister-cooling shaping-hair loss water. After taking out the plastic parts, reposition the wooden board (which can be received or automatically) for the next cycle.
Generally speaking, most customers who have been engaged in the blister industry for many years can judge by themselves and choose the right blister machine to produce. However, most customers may need the help of suppliers to decide what specifications of thick plastic machines to use, and even customers may only have samples or ideas of products, asking whether the manufacturer's machine can be produced and which model is more suitable. (David Ashek).
Generally speaking, the important factors that determine the choice include mold, product, plastic type, output requirements, etc., so the following information should be collected or retained before selection: product shape (length, width, height); product wall thickness, product use Type and quantity.
