1. Market and Production Overview of 2L Household Containers
1.1 Main Application Scenarios and Product Standards of 2L Containers
2L plastic containers are mainly divided into two core application categories in the consumer market: household daily chemical packaging and food storage packaging. In the daily chemical industry, 2L capacity is the mainstream specification for medium-sized laundry detergent bottles, hand sanitizer containers, dishwashing liquid bottles, body wash and shampoo packaging bottles. Such products require good chemical corrosion resistance, uniform bottle wall thickness, strong compression resistance, and smooth surface printing performance to adapt to daily chemical liquid storage, transportation extrusion, and market printing and labeling needs.
In the food storage industry, 2L sealed plastic jars are widely used for household grain storage, dried fruit preservation, snack storage, and small-batch food sealed packaging. Food-grade 2L containers must comply with strict food contact safety standards, featuring no harmful substance precipitation, good air tightness, anti-oxidation, anti-moisture permeability, and high structural stability to avoid deformation and cracking during long-term food storage and repeated cleaning.
In terms of industry production standards, 2L containers have strict requirements on capacity tolerance, wall thickness uniformity, sealing performance, and appearance flatness. The capacity error must be controlled within ±2%, the bottle wall thickness tolerance is stable within ±0.12mm, and the finished product has no bubbles, scratches, flash, and deformation defects. Only high-precision professional extrusion blow molding machine equipment can meet these standardized mass production requirements.
1.2 Industry Pain Points of Traditional 2L Container Production Equipment
Most traditional ordinary blow molding machines applied to 2L container production have prominent technical bottlenecks and production deficiencies. First, the parison extrusion stability is poor. Due to the large volume of 2L containers, traditional equipment is prone to uneven parison thickness and unstable extrusion volume, resulting in inconsistent bottle body wall thickness, local thin walls, and easy deformation and leakage of finished products.
Second, the production efficiency is low. Traditional semi-automatic blow molding equipment relies on manual auxiliary trimming and feeding, with low hourly output and long molding cycle. It cannot meet the large-batch and fast delivery demands of daily chemical and food packaging orders. Third, the hygienic level is insufficient. Ordinary equipment has dead corners for material residue and poor sealing performance, which easily causes material deterioration and container surface pollution, failing to meet food-grade production standards.
In addition, traditional equipment has high energy consumption and poor cost control capability. The unit energy consumption for producing 2L containers is high, and the defective rate remains at 6% to 10%, resulting in serious raw material waste and increased production costs, which greatly reduces the profit margin of packaging enterprises.
1.3 Core Equipment Requirements for Modern 2L Container Manufacturing
Modern large-scale production of 2L household daily chemical bottles and food storage jars puts forward four core requirements for extrusion blow molding machine equipment. The first is high-precision parison and wall thickness control capability to ensure stable capacity and uniform structure of large-volume containers. The second is hygienic and environmentally friendly molding configuration to meet food-grade and daily chemical packaging safety standards. The third is high-efficiency continuous automated production performance to adapt to large-batch order production. The fourth is low energy consumption and stable long-term operation to reduce comprehensive production costs.
The upgraded APOLLO 2L EBM machine fully covers the above industry core requirements through customized structural optimization and intelligent system configuration, becoming the preferred professional equipment for modern 2L medium-capacity household container production lines.
2. Working Principle and Standard Production Process of 2L EBM Machine
2.1 Basic Working Principle of Extrusion Blow Molding for 2L Containers
The 2L extrusion blow molding machine adopts the thermal plasticizing and pneumatic stretching molding principle, realizing one-time integrated molding of large-volume hollow containers. The whole production process is completed by the coordinated operation of the extrusion plasticizing system, hydraulic mold clamping system, constant-pressure blowing system, circulating cooling system, and intelligent control system. Firstly, food-grade and daily chemical-grade plastic particles such as HDPE, LDPE, and PP are evenly heated and plasticized in the extruder barrel to form stable molten plastic melt.
The precision screw extrusion system quantitatively extrudes tubular plastic parisons matching the 2L container specification. After the parison is extruded to the set length, the high-rigidity mold clamping mechanism quickly closes the mold to clamp and cut off the excess parison. Then, the high-purity filtered compressed air is injected into the closed mold cavity. Under stable air pressure, the plastic parison is evenly stretched and expanded, closely fitting the inner wall of the precision mold to form the outline of 2L bottles and jars.
Finally, the high-efficiency circulating water cooling system rapidly cools and shapes the container. After the internal stress is completely eliminated and the shape is fixed, the mold is automatically opened, and the finished product is demolded and output. The whole process is continuous and automated without secondary processing, which efficiently completes the production of qualified 2L daily chemical bottles and food storage jars.
2.2 Complete Production Process Flow for Household Containers
APOLLO 2L EBM machine formulates a standardized and refined production process for the structural characteristics and safety standards of household containers, ensuring stable quality of each batch of products. The first step is raw material pretreatment, including screening, impurity removal, and constant-temperature drying of plastic particles to remove moisture and dust impurities, avoiding bubble and particle defects on the surface of finished 2L containers.
The second step is segmented heating plasticizing. The extruder adopts multi-stage independent temperature control to accurately adjust the heating temperature according to different raw material characteristics, ensuring full and uniform melting of plastics without thermal degradation or coking residue, which lays a foundation for hygienic production.
The third step is intelligent parison extrusion and wall thickness adjustment. The equipment dynamically adjusts the parison thickness in real time according to the 2L container mold structure, realizing thickened reinforcement at the bottom and mouth of the bottle and uniform thickness of the bottle body, effectively improving the compression resistance and drop resistance of large-volume containers.
The fourth step is high-precision mold clamping and constant-pressure blowing. The stable mold clamping force eliminates flash and mold displacement defects, and the constant-pressure blowing technology ensures uniform stretching of the parison, smooth and flat container surface, and standard dimensional tolerance.
The fifth step is gradient cooling and shaping. Segmented cooling temperature setting eliminates internal stress of large-volume containers, preventing deformation, warping, and cracking of 2L bottles and jars during long-term use.
The sixth step is automatic demolding and finished product sorting. The equipment automatically outputs finished products and cooperates with the trimming system to complete edge cleaning, realizing continuous cyclic production and greatly improving production efficiency.
2.3 Key Technical Control Points for High-Quality 2L Container Molding
The production of qualified 2L household containers needs to focus on three core technical control points of the extrusion blow molding machine. First, parison stability control. Large-volume containers have high requirements on parison extrusion uniformity. Stable screw speed and die head pressure must be maintained to avoid parison deviation and thickness difference, ensuring consistent capacity and structure of finished products.
Second, blowing pressure and speed matching. Excessively high blowing pressure will cause local over-stretching and thin wall of the container, while excessively low pressure will lead to incomplete molding and unclear outline. The constant-pressure and variable-speed blowing system of APOLLO equipment can accurately match the optimal blowing parameters for 2L specifications to ensure full and uniform molding.
Third, cooling balance control. The large volume of 2L containers leads to a large heat dissipation range. Unbalanced cooling will cause inconsistent shrinkage rate and product deformation. The equipment adopts a multi-channel circulating cooling water system to realize synchronous and uniform cooling of the inner and outer walls of the container, ensuring stable product shape and dimensional accuracy.
