The basic method of vacuum forming machine, thermoforming blister sheet of knowledge

Plastic thermoforming method are many, according to the molding mould pressing and differential pressure power can be divided into two categories. According to the forming mould, can be divided into ChanYang mode, single cavity die, to die, no mold of several methods, such as

moulding, also known as mechanical stretch forming, is in the form of single mode or to die, with the help of plus mechanical pressure or weight, plastic sheets with molding into various parts of the molding method. Male mold refers to the shape of the mould is convex, cavity die refers to die of the concave shape, mold molding products only one side, the other side when it is exposed to the air, it is different from a forming process and forming. This method can be suitable for basic all thermoplastics.

blister products commonly used sheet are: PVC, PET, PP, PS, and on the basis of flocking sheet, gold-plated sheet and anti-static sheet. PVC:

the most common blister material, soft, strong toughness, good plasticity, but make it transparent and a variety of colors, the commonly used transparent PVC packaging electronics, cosmetics, toys, gifts and other products.

　　PET（ A - PET) : hard, good toughness, high strength, surface brightness, environmental non-toxic, transparent and a variety of color sheet. Defect is PET high frequency thermal bonding are difficult, the price is more expensive than PVC, this material has often been asked customers high-grade and environmentally friendly products to replace PVC

PS: density is small, Light) , environmental non-toxic, plasticity is very good, poor ductile brittle, not make it bright material, thus positioning vacuum forming machine can only make tap blister, because of its easy to crack, should not be such a blister recycling

PP: material of special soft, good toughness and environmental protection non-toxic, high temperature resistant, has often been made catering utensils or other high temperature resistant products packaging; But its poor plasticity, processing is difficult, the surface gloss, color will be shallow and processing.

　　PET- G: physical properties with A minus PET is similar, but can be high frequency thermal bonding, its price is A - PET is also 80% more expensive

blister light boxes made of blister sheet of the characteristics and USES:

blister light boxes is forming by the method of using blister light boxes, the shape of a square, circular profile (and Other geometric shape) And so on. Blister light boxes of skeleton composed of aluminum bending, lu: xingcai width is 6 cm, 8 cm, to 10 cm, 11. 5 cm, etc. , can be determined according to the light box size or customer to choose suitable width. Dimension large light box available steel reinforcement. Light box feet depending on the installation, T, a perfectly on the cylindrical embrace hoop, etc. Light box piece of yakeli board after heating by vacuum forming machine is out of a raised surface of the panel as a light box, also can press down. It can be widely used in banking financial institutions, road signs, each store appearance, bank outlets, chain, various shopping malls, supermarkets, city street road bar, used as a trademark, indicator, publicity show etc.

the characteristics and advantages of blister light boxes:

1. Effect of colorful, eye-catching

2. High temperature resistant, resistant to climate change and environmental}

　　3. Not easy deformation, not easy fade, 8 - generally can protect color 10 years)

　　4. Good corrosion resistance

5. Waterproof, fire prevention, prevent spontaneous combustion

it is imported from abroad in recent years a new type of outdoor media, as the avant-garde in advertising promotional products, 3 d stereo sense is strong, rich colors, low cost, has been favored by the customers, its application and development is very fast.
