Cosmetic bottle making machine is a specialized equipment for manufacturing various plastic bottles and containers used in the cosmetics and personal care industries. It mainly uses advanced forming technology to transform plastic materials such as PET, PP, and PETG into bottles of various shapes and sizes. The key technologies used in cosmetic bottle making machine include injection stretch blow molding, injection blow molding , extrusion blow molding, etc. These technologies process plastic particles into bottles of various shapes and specifications to meet the aesthetic, sealing and functional requirements of cosmetic packaging. Meanwhile, cosmetic bottle making machine is equipped with servo drive motors, PLC control systems and mold temperature control system to ensure quality of the bottles and accuracy of production. In addition, the features of high-precision and high degree of automation enable cosmetic bottle making machine to significantly enhance production efficiency and product consistency, while reducing labor costs. It is an indispensable equipment in the modern cosmetics manufacturing industry.

Cosmetic bottle making machine can support multi-chamber production, meet the demand for large quantities and provide flexible production functions to produce different types of bottle designs, customizing shapes and sizes. Therefore, from standard cylindrical cosmetic bottles to various customized requirements, all can be fulfilled. Cosmetic bottle making machine is widely used in the beauty and personal care industries to produce high-quality plastic packaging for various product categories. From skin care and hair care to perfumes and cosmetics, the machine offers the required flexibility, speed and precision to meet diverse market demands and aesthetic preferences. It is an indispensable equipment in today’s beauty industry, playing a crucial role in connection design, functionality and production efficiency of cosmetic bottle making.

Working Process of Cosmetic Bottle Making Machine

Raw material heating

Preform forming

Heating adjustment

Mold forming

Shaping and cooling

Demolding and removal

The working process of cosmetic bottle making machine is not a single linear process, but a continuous technological flow that includes multiple stages such as raw material heating, preform forming, heating adjustment, mold forming, shaping and cooling, demolding and removal. The entire making process is monitored and coordinated throughout by a central control system like PLC and HMI, achieving functions such as automated production, parameter tracking, which enhances product consistency and production efficiency.

Raw material heating: The plastic particles are conveyed into the heating chamber through the feeding system and heat the material to a molten state.
Preform forming: The molten material is conveyed to the mold through the injection molding system to form a preform. Its molding quality will directly affect the mechanical properties and aesthetic appearance of the final bottle.
Heating adjustment: After the preform is formed, it enters the heating module through the conveying system for preheating or temperature adjustment, with the aim of achieving an appropriate plastic state.
Mold forming: After the mold is closed, the mechanical system controls the stretching device and the air-blowing device to work in coordination, causing the preform to rapidly expand and adhere to the mold cavity under the dual action of longitudinal stretching and transverse air pressure.
Shaping and cooling: When the mold comes to a cooling state, the bottle is rapidly cooled to a stable structural temperature by means of circulating water or air cooling.
Demolding and removal: The bottle is separated from the mold through the demolding system and sent out by the mechanical arm or conveyor belt.
