What is a blow molding -XJ BEAUTY

process:

the bottle: PP and ABS bottle mostly pure color, PETG material and acrylic bottle mostly transparent color, there are clear, most acrylic bottle wall for spraying color, can be refracted light, the effect is good.

printing: the bottle can be screen printing, hot stamping or silver. Double cover cover can be silk screen printing, and cover is transparent and transparent. The shell made of anodic aluminum oxide with out logo.

( 2) Vacuum flask + pump cranium ( Semen bottle, toner bottle, lotion bottle) , injection molding vacuum bottles used AS materials, can be directly contact with paste, without straw, vacuum design) + pump head ( Plating) Cover ( Transparent and pure color)

production process: vacuum bottles used more in transparent color, while in the aspect of pure color less.

printing: the bottle can be screen printing, hot stamping or silver.

( 3) , bottle blowing

( Elite fluid bottle or lotion bottle, toner bottle) ( Production machine, blow molding machine)

。 Understand blowing process

cosmetics manufacturer packaging material cosmetics manufacturer manufacturer according to the plastic material, can be divided into PE blow molding, More soft, pure color, a molding) , PP blow molding ( More hard, solid color, a molding) , PET blow molding ( Translucent, toner and hair care products) 。 , it is a kind of environmental protection material, secondary molding) , PETG bottle blowing, Transparency is better than that of PET, but are not commonly used in China, the cost is high, the cost is high, the one-time molding, not recycled materials) Less.

combination forms: inside the bottle blowing + plug ( Used for PP and PE material) + shell ( Used for PP and ABS and acrylic acid, but also used in electroplating and anodic aluminum oxide, the main use of injection of carbon powder) Or pump cranium ( Serum and often use lotion) ) Before + ball cover + flip cover ( Flip cover and before the ball is mainly used for large-scale circulation daily chemical production line) 。

B。 Processes for the production of bottle blowing:

the bottle: the bottle of PP and PE materials use more pure color, PETG, PET, PVC materials mostly use the transparent color, or colored transparent, clear, pure color is less. PET bottle can also spray color.

printing, screen printing, hot stamping, hot stamping.

( 4) Pump head

1. Distributor is divided into two kinds: mouth type and screw type. From the point of view of function, it is divided into spray, foundation cream, emulsion pump, aerosol valve and vacuum flask.

2。 The size of the pump head depends on supporting the calibre of the bottle. Spray specification of 12. 5mm- 24 mm, water yield of 0. - 1 ml/time 0. 2 ml/time. It is usually used in perfumes, gel water and other products packaging. According to the height of the bottle that specifies the length of the same purchase.

3。 Emulsion pump specifications for 16 ml to 38 ml, water yield of 0. 28 - ml/time 3. 1 ml/time. It is usually used in creams and washing products.

4。 Vacuum flask is usually cylindrical, the specification of 15 ml - 50 ml, 100 ml. Rely on the principle of atmospheric pressure, the total capacity is relatively small, can avoid the pollution in the process of cosmetics manufacturer use. Vacuum flask anodic alumina, plastic coating and colored plastic, than other ordinary container is expensive, general order quantity is not high.

For the study, researchers defined XJ BEAUTY as strategies to foster some social good, including programs that benefit community engagement, diversity, the environment, human rights and employee relations.
