Medicine Bottle Blow Molding Machine

Medicine bottle blow molding machine focus on medical plastic injection molding.

What is Medicine Bottle Blow Molding Machine?

Medicine bottle blow molding machine is an automated forming machine specifically designed for medical bottle manufacturing. It is widely used in the production of various medicine bottles such as pill bottles, eye drop bottles, tablet bottles and disinfectant bottles. Compared with ordinary plastic bottle making machine, medicine bottle blow molding machine has higher requirements for product forming accuracy, material cleanliness and production process control. Particularly, it needs to meet strict regulations such as hygiene standard, sealing performance and physical strength for drug packaging. Medicine bottle making machine mainly heats the plastic raw materials to a molten state, controls their shape and size through molds and uses compressed air to inflate the plastic to the inner wall of the mold cavity to form the bottle body. Compared with traditional glass bottles, plastic medicine bottles are gradually replacing glass packaging due to their light weight, durability, good sealing performance and low susceptibility to contamination. They are particularly prominent in oral liquid, children’s medicine and vaccine products.

With the rapid development of the global pharmaceutical industry and the increasing emphasis on the safety of drug packaging, plastic medicine bottle making machine, as a key link in the medical packaging industry chain, is increasingly demonstrating strong application value and development potential. This machine supports long-term operation, features high production efficiency and complies with energy-saving and environmental protection design, effectively lowering energy consumption and carbon emissions. Therefore, medicine bottle blow molding machine designed in accordance with modern industrial standards not only enhances packaging efficiency but also promotes the standardization and intelligence process of the entire pharmaceutical packaging.

Working Principle of Medicine Bottle Blow Molding Machine

Medicine bottle blow molding machine mainly processes plastic raw materials into hollow medicinal plastic bottles through blow molding technology. Its working procedure is a very simple, fully automated operation. The following is the working principle of medicine bottle blow molding machine:

Raw material preparation and preforming
Medical-grade plastic raw materials such as polyethylene (PE) are added to the hopper of medicine bottle making machine and heated to a molten state through the heating system. During this process, the screw keeps rotating, pushing the molten plastic forward to be evenly mixed and plasticized. Then, the molten plastic is injected into the mold cavity to form the preform.

Air blow molding
When the preform is ready, the mold is closed and the preform is clamped into the mold. Then a blow rod is inserted into the interior of the preform and compressed air is injected into it at high speed. Under the action of high-pressure air flow, the preform rapidly expands and adheres to the inner wall of the mold, forming the final shape of the medicine bottle. This process requires uniform blowing and stable pressure to ensure that there are no bubbles or deformations on the bottle body.

Cooling and demolding
The formed medicine bottles are kept in the mold for a certain period of time to cool down and then rapidly cooled through the cooling water channels to ensure the plastic shape molding. After the cooling is completed, the automatic device takes out the formed medicine bottles for subsequent processes such as inspection and packaging.

Raw Materials of Medicine Bottle Blow Molding Machine

HDPE(High-Density Polyethylene)
HDPE is the most common raw materials in medicine bottle manufacturing. It can effectively resist various corrosion of various pharmaceutical components due to the excellent chemical stability and mechanical strength. Its material is sturdy and not easily broken. Therefore, it is especially suitable for the packaging of solid medicine with high safety requirement.

LDPE(Low-Density Polyethylene)
LDPE features softness, elasticity and low-temperature resistance, making it suitable for the production of small container that requires manual extrusion or flexible structures. In the field of pharmaceutical packaging, LDPE is often used in the manufacturing of soft bottle types such as eye drop bottles and nasal drop bottles.

PP(Polypropylene)
PP is a plastic material that combines high-temperature resistance and chemical resistance, which is widely used in the production of pharmaceutical container that requires high-temperature sterilization or hot filling. Its transparency is moderate and can be clearly observed on the bottle body. It is often used for packaging liquid medicines such as syrup bottles and oral liquid bottles.

PET(Polyethylene Terephthalate)
PET is a thermoplastic with high transparency and excellent air tightness. It is often used to make transparent medicine bottle, such as vitamin water bottle and nutrient solution bottle. Its appearance is smooth and the texture is excellent. At the same time, it has the ability to resist penetration and deformation, effectively protecting the active ingredients.
