3L Laundry Detergent Bottle Double Station Double Die Head Extrusion Blow Molding Machine, Empowering Packaging Production Upgrade

In the daily chemical packaging field, 3L laundry detergent bottles have become a mainstream choice for household consumption and small supermarket procurement due to their moderate capacity design. Their production efficiency and product quality are directly related to the market competitiveness of daily chemical enterprises. To address the pain points of traditional equipment such as "low single-unit output, slow model changeover, and high energy consumption", we have developed and launched the 3L Laundry Detergent Bottle Double Station Double Die Head Extrusion Blow Molding Machine in a targeted manner. With the core advantages of dual-station collaborative operation and dual-die head precise shape control, it redefines the efficiency and quality standards for large-scale production of laundry detergent bottles.

Precise Demand Matching: A Tailor-Made Production Solution for 3L Laundry Detergent Bottles

Aiming at the characteristics of laundry detergent bottles, such as "thick bottle body and precise bottle mouth thread", the equipment adopts a customized die head runner design to ensure uniform melt distribution and avoid defects like uneven thickness, bubbles, and depressions on the bottle body. At the same time, it is adapted to the exclusive mold size of 3L bottle type and combines with a servo drive system to precisely control the mold opening and closing speed and pressure, ensuring that each batch of products maintains highly consistent appearance and dimensional accuracy, fully complying with the strict quality inspection standards of the daily chemical industry.

Core Technological Breakthrough: Double Station + Double Die Head, Unlocking Dual Upgrades in Efficiency and Quality

The collaborative design of double stations and double die heads is the core competitiveness of this equipment. Through the technical combination of "parallel operation + precise temperature control", it achieves the simultaneous improvement of production capacity and quality. The specific advantages are reflected in three dimensions:

1. Dual-Station Parallel Operation: Doubled Production Capacity, Reduced Costs and Increased Efficiency

The equipment adopts an independently controlled dual-station structure, and the two stations can simultaneously carry out the whole process of "extrusion - blow molding - demolding". Compared with traditional single-station equipment, the production capacity is directly increased by 80%-100% within the same time, and the daily output of a single equipment can reach 8,000-12,000 bottles, easily meeting the large-order demand of daily chemical enterprises. At the same time, the dual stations share the same set of feeding and temperature control systems. On the basis of doubled production capacity, it effectively reduces the energy consumption and labor cost per unit product, helping enterprises significantly improve production profit margins.

2. Precise Shape Control by Double Die Heads: Stable Quality, Adapting to Diverse Needs

Equipped with two sets of independent precision die heads, it supports differential control of the melt temperature and extrusion speed of two bottles. It can not only produce 3L laundry detergent bottles of the same specification at the same time but also flexibly switch according to needs to produce derivative products of different bottle shapes and thicknesses (such as 3L softener bottles, disinfectant bottles, etc.). The die head is treated with hard chrome plating, and the runner is smooth without dead ends, which effectively reduces melt retention, ensures uniform color and luster of the bottle body without black spots and impurities. Moreover, the bottle mouth thread is clear and complete, and the pass rate of screw cap sealing is increased to more than 99.8%.

3. Intelligent Control System: Convenient Operation, Worry-Free Operation and Maintenance

The equipment is equipped with a 7-inch color touch screen, with a dedicated production parameter template for 3L laundry detergent bottles built-in. Operators only need to call it with one click to start production, which greatly reduces the pre-job training cost. The system has a real-time monitoring function, which can dynamically display and alarm abnormalities of key data such as temperature, pressure, and output. At the same time, it supports automatic storage and export of production data, facilitating enterprises to carry out production process traceability and management. The key components of the equipment are all from well-known international brands, and combined with modular design, the subsequent maintenance is simple and convenient, effectively reducing downtime.

Full-Scenario Adaptation: An All-Round Choice from Small and Medium Batch to Large-Scale Production

Whether it is small and medium batch trial production for start-up daily chemical enterprises or large-scale production for large groups, this equipment can be accurately adapted with its flexible configuration and stable performance. Aiming at the production characteristics of 3L laundry detergent bottles, the equipment is compatible with various food-grade raw materials such as HDPE and PP, and supports the addition of recycled materials (proportion ≤ 30%), helping enterprises reduce raw material costs while ensuring quality. At the same time, the equipment reserves an automatic docking interface, which can be linked with subsequent equipment such as cap assembly lines, labeling machines, and cartoning machines to build a fully automatic production line and further improve production efficiency.
