The advantages of twin neck bettix bottle

High density polyethylene (HDPE ) is the most commonly used resin. This economical plastic has good impact resistant, is naturally translucent, flexible, and typically used for personal care products, such as shampoo bottles. Adding color will give HDPE an opaque look that will result in an increase in weight and rigidness.
Plastic twin neck bottles are double neck bottles that allow for controlled dispensing and the second chamber eliminates the need for additional measuring. Double neck bottle is suitable for industrial, agricultural and animal care products.
HDPE liquid bottle has two chambers, one for storing and the other for measuring exact doses. The second chamber is designed to eliminate additional measuring by providing precise pouring every time.
To use, squeeze the bottle to fill the measuring chamber with desired amount of liquid. Then, remove the cap and easily pour measured liquid from the chamber. The twin neck bottle is often used for industrial, as well as agricultural and animal care products.

The structure of effervescent tablet tube's desiccant cap

The effervescent tablet tube's desiccant cap serves as a container for protecting medicines from moisture or damage to medicines, health foods and diagnostic products. The bottle body and cap form a sealing system to prevent sensitive products from getting wet, prolong the shelf life and enhance brand value. The moisture-proof combination bottle body and cap use special design features and plastic materials to prevent moisture from entering and absorb moisture generated by water vapor transmission effect. The moisture-proof combination cover features include:
1. Anti-theft ring: There is no bottle buckle at the bottle neck. When the moisture-proof cover is covered, the anti-theft ring will be stuck. When it is opened, the anti-theft ring will automatically fall off.
2. Sealing: It adopts double material system (polyethylene cap and polypropylene bottle body) and innovative shaping design. The sealing and container are perfectly sealed, and the water vapor transmission effect is strictly controlled.
3, cork spring: optional cap to ensure that the tablet does not shift, especially during transportation, to avoid the bumps affected by the bumps
4, desiccant: the desiccant chamber of the bottle cap can be used to match the desiccant of various types, quantities and attributes to ensure that the product is properly protected.

The productive process of veterinary vaccine injection bottle

The production cycle of veterinary vaccine bottle which is produce by injection moulding is short and high efficiency,The injection moulding technology can produce complex shape bottle,high-precision size plastic bottles.These bottle can't be easily produced by other forming methods,so many plastic bottle factory use the injection moulding technology to produce their bottls,in the second place,the injection moulding technology can easilly realize automation,such as injection process,demould process and cutting pouring gate all can realize automation,so the injection moulding is used more and more widely.

Today i will introduce the productive process of veterinary vaccine bottles.

The veterinary vaccine bottle's injection moulding theory is that fill the powdery or granuliform PE or PP raw material in the gunk of injection machine,this raw material is heated and melted in injection machine and keep the raw material flowing,then the injection machine inject the flowing liquid raw material to the closed mould,then cooling the raw material,the melted raw material will solidify,and you can get the veterinary vaccine bottle.

The injection moulding technology also has some disadvantages,first,the injection equipments is higher,second the structure of mould is complex and the produce cost is higher,so this process is not suitable for small amount produce.

The followings are some notices when you are in the injection moulding process.

Before starting the produce the vaccine bottle,you need preheat and dry the raw material,wipe off the redundant moisture and volatile matter,if you do like this,you can prevent that the plastic bottle degrades and has imperfection which can influence the appearance and quality
when you change raw material or product,you need wash the charging barrel
The finally,i will integrally introduce the injection moulding

set the injection moulding parameter,like temperature,pressure and time
prepare the injection mould,prepare the mold carefully keeping the dimensions and specifications in check
injection the molten plastic,
packing of the mold
cooling of the mold
ejection of the mold
These are productive process of veterinary vaccine bottle.
