Machine introduction
The principle of blister forming machine: blister forming is also called thermoforming. This forming process mainly uses the vacuum suction generated by a vacuum pump to soften the heated PVC, PET, PETG, APTT, PP, PE, PS and other thermoplastic
Plastic sheets The material is vacuum-formed into various shapes of vacuum hoods through molds, or attached to the surface of various shapes of products. According to the thickness of the sheet, the blister is divided into thin blister and thick blister.
The main structure of the machine is composed of feeding, drawing, upper and lower electric heating furnace, lower gate, multi-functional adjustable size, lower mold plate, upper mold, upper gate, knife gate, slicing, placing film, and vacuum equipment. ;
The common products of thick plastic blister include: household appliance inner shell, luggage, display rack accessories, decoration, car interior, bumper, mudguard, beauty equipment, light box shell, toy car shell, industrial panel, advertising light box, Blister LOGO, bathroom products, refrigerator liner, etc.
Main application of this paragraph
Plastic packaging industry (blister packaging, plastics, batteries, toys, gifts, hardware, home appliances, electronics, stationery, decoration)
Food packaging industry (fast food boxes, fruit trays, biscuit boxes)
Pharmaceutical industry (pill packaging, tablet packaging)
Industrial cooling tower cooling water deflector, etc.
Three-dimensional relief patterns for decoration, plastic ceilings, wall panels, automotive materials, sanitary equipment and other manufacturing industries.
Suitable for the production of various color sheets: polyethylene PS, polyvinyl chloride PVC, plexiglass, ABS, polymethyl methacrylate; flocking sheets; environmentally friendly sheets APET, PET, PP, etc.; photodegradable materials; biodegradable Materials and other plastic products.
Folding edit this paragraph forming technology
The blister molding technology, namely the thermoforming processing technology of plastic sheet (board) material, is one of the industrial technologies in the secondary processing of plastics. It is different from the one-time processing technology such as injection molding and extrusion. It is not for plastic resin or pellets for heating molding or continuous molding with the same cross-section through the die; nor is it using machine tools, tools and other mechanical processing methods to cut a part of plastic materials Next, to obtain the required shape and size, but for the plastic sheet (board) material, heating, using molds, vacuum or pressure to deform the sheet (board) material to achieve the required shape and size, supplemented by supporting procedures to realize the application purpose.
The blister molding equipment includes clamping system, heating system, vacuum and compressed air system, and molding mold.

Blister machine Blister machine
⑴Strong product specification adaptability The blister molding method can be used to manufacture various products of extra large, extra small, extra thick and extra thin. The sheet can be as thin as 1~2MM, or even thinner, and the product area can be as large as 10 square meters. To a few square millimeters, the wall thickness can be as large as 20mm and as small as 0.1mm.
⑵The product has a wide range of applications. Daily necessities blister packaging, hardware blister packaging, automotive supplies blister packaging, electronic product blister packaging, food blister packaging, cosmetics blister packaging, computer peripheral equipment blister packaging, toy blister packaging, sports Blister packaging for supplies, blister packaging for stationery, etc.
⑶ Less equipment investment
⑷It is convenient to make molds,( 58708187, 58708110,there are plaster molds, copper molds, aluminum molds~~~~)
⑸ Higher production efficiency.
(6) Save raw and auxiliary materials, light weight, convenient transportation, good sealing performance, and meet the requirements of environmentally friendly green packaging; can package any special-shaped products without additional cushioning materials for packing; the packaged products are transparent and visible, beautiful in appearance, and easy to sell , And suitable for mechanized and automated packaging, convenient for modern management, saving manpower, and improving efficiency
Commonly used plastics and properties for thermoforming
According to their heating behavior, plastics can be divided into two categories: thermoplastics and thermosetting plastics. Most of the materials used for thermoforming are thermoplastic materials.
Whether single-layer or multi-layer composite plastic sheet (board) materials used for thermoforming processing must have the following process properties
1: Plastic memory
2: Hot stretch
3: heat intensity
4: Molding temperature
Thermoforming commonly used plastics
1. PVC (Characteristics: less impurity content, better transparency, lower price, good dielectric properties, flame retardancy and self-extinguishing)
Two PP (rich sources, low price, excellent performance, wide range of uses.
1. Low density (PP is colorless, odorless, tasteless, non-toxic, flammable, white in appearance, and density is 0.90~0.91g/㎝3.)
2. Good mechanical properties The rigidity of PP, especially good extensibility, and good stress crack resistance
3. Better heat resistance
4. Good chemical stability
5. Transparency, good water resistance and waterproof
6. Strong processing and usability
Three PE (it is currently one of the largest and most widely used plastic varieties, odorless, tasteless, non-toxic, flammable)
Four PS (plastics are hard, brittle, transparent, odorless, emit black smoke when burned, easy to dye and process, low moisture absorption, dimensional stability, good electrical and thermal insulation.)
1. High transparency and gloss
2. Excellent coloring and hygienic performance
3. Excellent dielectric properties
4. Excellent molding performance
Disadvantages:
1. Brittle
2. Poor heat resistance
3. Moisture-proof, poor oxygen barrier
Five ABS (opaque, non-toxic, tasteless)
Six PET (colorless, odorless, tasteless, non-toxic, excellent transparency, excellent mechanical strength, abrasion resistance and electrical insulation properties, good creep resistance, rigidity and strength. Excellent hygiene allows it to Direct contact with food)
