Its main structure is composed of feeding, drawing, electric heating furnace, lower gate, multi-functional adjustable size, lower die disk, upper die, upper gate, knife gate, slicing, releasing plate and vacuum device.
With the pneumatic device as the main power source, vacuum forming machine is made with the pull piece, feed piece using electric, reducer, time relay, intermediate relay, travel switch and other electrical components of its automatic control system.
The requirements of the control system of vacuum forming machine are to ensure convenient operation, high precision of mechanical action and temperature control, short production time, and save the power consumption of vacuum forming machine as much as possible under the same production conditions.
Vacuum molding machine is mainly used in plastic packaging industry (blister packaging, plastic, batteries, toys, gifts, hardware, home appliances, electronics, stationery, decoration);
Food packaging industry (fast food box, fruit tray, cookie box);
Pharmaceutical industry (pill packaging, pill packaging);
Industrial cooling tower cooling water diversion sheet plate;
Decorative three-dimensional relief patterns, plastic ceilings, siding, automotive materials, sanitary equipment and other manufacturing industries.
Vacuum blister forming process is a thermal forming process of vacuum forming machine.
A method of manufacturing open shell products from thermoplastic sheets.
The plastic sheet is cut into a certain size and softened by heating. With the help of the air pressure difference or mechanical pressure on both sides of the sheet, the plastic sheet is deformed and then overlaid on the specific mold contour surface. After cooling and shaping, the plastic sheet is cut and trimmed.
Vacuum forming machine this forming method relies on vacuum force to make the sheet stretch and deform.
Vacuum force from vaccum forming machine is easy to realize, grasp and control, so simple vacuum forming is the earliest and most widely used thermal forming method at present.
Vaccum forming machine that wraps product with thermal shrinkage film and then heats it to shrink the film and then wraps the product. According to the type of vaccum forming machine, it can be divided into drying tunnel type, drying oven type, frame type and gun type.
The shrink packing machine adopts direct far-infrared radiation heating all kinds of thin film, product by belt conveyor to shrinkage furnace, the product with shrink packaging film, sealing after enter the shrink packing machine, automatic product shrinkage, heat shrinkable packaging machine power consumption is small, the average power consumption per hour largest and only 2.1 KW, contraction achieve perfect packaging effect, never affect packaging, electronic continuously variable, controlling temperature solid-state voltage regulators, stable and reliable
The development history of vacuum blister forming technology:
In the plastic production and processing industry, vacuum blister forming has become a widely accepted term in the industry.
What is the background of vacuum blister forming process? What has it experienced? How can it start and develop rapidly?
As early as the beginning of the 20th century, vacuum blister forming technology has been known;
After the 1940s, it began to be used in industrial production.
But until the 1960s, vacuum blister began to have a greater development, is widely used by people.
Vacuum blister technology has been developed along the way, and it has become one of the important methods of processing packaging materials.
The wheel of history is turning and The Times are progressing.
There are several reasons for the development of vacuum blister forming technology today, part of which is due to the continuous innovation of vacuum blister forming technology and equipment, as well as the development of new materials with molding properties.
The other part is related to the development of packaging industry and the characteristics of vacuum blister forming packaging itself.
In the industry, vacuum blister forming process by vaccum forming machine is undoubtedly one of the most commonly used plastic packaging containers forming methods.
It takes thermoplastic sheet material as the forming object, for some developed countries abroad, vacuum blister forming is a relatively old forming process.
With the progress of technology and the development of science and technology, the current vacuum plastic has been highly automated, mechanized, and do not have any waste edge material to produce, 100% of the raw and auxiliary materials into products.
And formed a full - line production of the forming system engineering: auto vaccum forming machine.
