20L Bottle Blow Molding Machine

High Production Efficiency
20L bottle blow molding machines are designed for high-speed production, enabling manufacturers to produce large quantities of bottles in shorter timeframes. This increased output translates to higher productivity and more efficient use of resources, ultimately reducing the cost per unit of production. This machines are equipped with state-of-the-art automation features that ensure precise control over the production process. Automation minimizes human error, enhances product consistency, and reduces the need for manual labor. This precision leads to fewer defective products and less material waste, contributing to cost savings.

Material Optimization
20L bottle blow molding machines are engineered to optimize material usage. By precisely controlling the molding process, our machines minimize scrap and ensure that each preform is fully utilized. This efficient use of materials not only reduces waste but also lowers raw material costs, making production more economical. Our advanced technology enables the production of lightweight bottles without compromising strength or quality. Lighter bottles require less plastic, reducing material costs. Additionally, lighter products can lower shipping costs and reduce the environmental impact of transportation, providing further savings.

Energy Efficiency
20L bottle blow molding machines are designed with energy efficiency in mind. Features such as variable frequency drives (VFD) and energy-saving heating systems optimize power consumption, reducing electricity usage and operational costs. Lower energy consumption not only cuts costs but also supports sustainability initiatives. This machines incorporate efficient cooling systems that reduce cycle times and enhance overall production speed. Faster cooling times mean quicker production cycles and lower energy usage per bottle produced, further contributing to cost savings.

Labor Cost Reduction
20L bottle blow molding machines offer advanced automation that reduces the need for manual labor. Automated systems handle tasks such as preform loading, bottle ejection, and quality inspection, freeing up workers for other critical tasks. This reduction in labor requirements leads to significant savings on wages and associated labor costs. 20L bottle blow molding machines feature user-friendly interfaces that simplify operation and reduce the need for extensive training. Easy-to-use controls and automated settings minimize operator error and ensure consistent production quality, further reducing labor-related costs.

Material Preparation
The blow molding process begins with the preparation of raw materials, typically high-density polyethylene (HDPE), polypropylene (PP), or polyethylene terephthalate (PET). These materials are melted and formed into a parison, a hollow tube-like shape.

Parison Extrusion
The parison is extruded from the machine's die head, which precisely controls the dimensions and thickness of the product. The parison is continuously extruded and clamped between two halves of a mold, forming a cavity.

Mold Closing
Once the parison is extruded, the mold halves close around it, creating a sealed environment for the next step. The mold design defines the final shape of the product.

Blow and Hollow Formation
Compressed air is introduced into the parison, forcing it to conform to the shape of the mold. This air pressure expands the parison, creating cavity walls and hollowing out the product.

Cooling and Solidification
After the blow, the mold is cooled to facilitate solidification of the plastic. Cooling can be achieved through direct contact with cooled surfaces or by circulating a coolant within the mold.

Mold Opening and Ejection
Once the plastic has cooled and solidified, the mold halves open, and the final product is ejected. The excess plastic material, called flash, is trimmed off to achieve the desired shape.

Finishing and Quality Inspection
The ejected product undergoes finishing processes like trimming, labeling, and quality inspection to ensure it meets the specified standards. This step ensures that only products with the highest quality are sent to the market.

What should I do with the bottom of the bottle blown by the bottle blow molding machine?
The common factor for bottle accumulation is that the stretching rod is not adjusted in place. It is recommended that the stretching ratio between the preform and the bottle body is preferably 1:2.5 (excluding the mouth part), and at the same time adjust the heating temperature to extend the pre-blowing.

What should I do if the bottle's mouth-blown by the bottle blow molding machine is deformed?
Bottle mouth deformation Generally, during the heating process of the preform, the transmission chain drives the bottle base to transfer the temperature to the preform mouth. During the heating process, the temperature continues to accumulate, and the bottle mouth bulges and deforms. It only needs to increase the air-cooling or water-cooling of the bottle mouth. If the customer's conditions permit, you can refer to the imported machine to install central air-conditioning in the production workshop to keep the ambient temperature of the workshop at an average temperature.

How can the bottle-blowing machine be operated, and which accessories should be checked?
As long as the equipment is controlled strictly following the method in the instruction manual and the performance of each safety door is checked regularly, the equipment as a whole is safe. However, the most significant hidden danger of the equipment is mainly on the seals of the water jacket and air jacket. For example, the water and air jacket are damaged, and the maintenance works are more troublesome.

How much chiller is needed for the carbonated beverage bottle blow molding machine to blow the bottle?
The chiller for the carbonated bottle is about five times larger than the chiller for the water bottle. A simpler algorithm can be calculated at 1200 bottles/hp; for example, 36000 bottles/hour can equip with a 30-hp chiller. To ensure the stress requirements of the carbonate bottle bottom, the cooling time is generally 1.2 seconds, and the bottom mould temperature is 11 degrees. The number of lamp zones in the heating furnace can refer to the configuration of the hot filling machine, and the adequate heating time of the preform should be no less than 33 seconds.

What is the highest temperature resistance of the non-crystalline bottle mouth of the hot-filling bottle blow molding machine? How many grams of preforms are needed?
At present, the preform mouths used in the production of hot-filled bottles in the industry are generally divided into crystalline mouths and non-crystalline mouths, and non-crystalline mouths are divided into 28 months and 38 months.
