EP-HGA.JS-2C366(20L) Large-Volume Blow Molding Machine for Pesticide & Chemical Containers<\/h2>\n

The EP-HGA.JS-2C366(20L) represents the high end of the ES series product line \u2014 a purpose-built, two-step blow molding machine engineered for large-volume pesticide, industrial chemical, and agrochemical container production. With a maximum container capacity of 22,000 ml (22 litres) and a dual-cavity configuration, this machine occupies a category that very few fully automatic blow moulding machine platforms can address: blow-moulded PET and PC containers in the 5\u201320 litre range that must meet the dimensional precision, wall uniformity, and chemical resistance standards demanded by leading agrochemical formulators worldwide. Wherever large-format pesticide containers, 10-litre detergent drums, or 20-litre chemical jerricans are required \u2014 in Colombia, Brazil, Southeast Asia, or any major agricultural market \u2014 the JS-2C366(20L) delivers production-grade reliability.<\/p>\n

Unlike smaller-cavity machines that struggle with the long stretching stroke and high blow-air volumes that large containers require, the JS-2C366(20L) was designed from the start for this demanding application. Its 620 mm stretching stroke and 12,500 ltr\/min high-pressure air circuit provide the energy and mechanical travel needed to fully inflate a preform into a 480 mm tall, 300 mm diameter container at 35 kg\/cm\u00b2 \u2014 producing a biaxially oriented wall that resists both the chemical content and the rough handling typical of field-use agrochemical packaging.<\/p>\n<\/div>\n

Large-Format Container Production: What Sets the JS-2C366(20L) Apart<\/h2>\n

Large-volume container production presents challenges that are qualitatively different from those in small-format bottle manufacturing. When a preform weighing 300 g or more is being inflated into a 20-litre container, the stretch-blow window \u2014 the narrow band of preform temperatures within which the material will orient correctly \u2014 is shorter and more sensitive to variation than in a 500 ml preform. Any deviation in preform temperature uniformity across its wall cross-section results in localised thinning, which in turn creates potential stress-crack initiation sites that can fail catastrophically in chemical service. The JS-2C366(20L) addresses this through its 86 kW infrared heating system, divided into independently controlled zones that maintain the preform body within a tight temperature envelope from the neck support ring to the gate, regardless of the preform’s wall thickness distribution.<\/p>\n

The machine’s two-cavity blow station is configured for the large mold dimensions that containers in this volume range demand. The mold-open distance of 772 mm and clamping stroke of 332 mm accommodate blow molds with the external dimensions needed for 300 mm diameter containers, while the toggle-lever clamping mechanism maintains consistent closing force across both cavities simultaneously. At 700 bottles per hour theoretical output, the JS-2C366(20L) is positioned for operations where production runs are counted in days rather than hours \u2014 typical of large-volume agrochemical container lines supplying seasonal crop-treatment campaigns in Colombia, Brazil, India, and comparable agricultural markets.<\/p>\n<\/div>\n

Key Advantages of the JS-2C366(20L) Blow Molding Machine<\/h2>\n

Producing large-format chemical and pesticide containers on an automatic pet blowing machine at the quality level that major agrochemical brands require is a fundamentally different engineering challenge from small-bottle production. The JS-2C366(20L) Blow Molding Machine was designed around four core requirements that define performance in this application: thermal control over heavy preforms, adequate mechanical travel for tall containers, sufficient air-flow capacity for large internal volumes, and robust mold clamping across wide-face tooling. Each of these requirements has driven specific design decisions that distinguish the JS-2C366(20L) from adapted small-format machines that are sometimes offered for large-container applications.<\/p>\n

The 86 kW heating system \u2014 the highest in the ES series \u2014 provides the thermal capacity to condition preforms weighing upwards of 250 g within the production cycle time required to sustain 700 bph output. The independent zone controllers allow the operator to establish a temperature gradient across the preform body that compensates for the non-uniform wall cross-section typical of heavy preforms, preventing the localised thinning that leads to gate-area stress cracking in service. The 120 ltr\/min cooling water circuit \u2014 more than three times the flow of the smallest ES models \u2014 supports rapid mold cool-down after each blowing cycle, maintaining cycle time even when mold face areas are large and thermal mass is high.<\/p>\n
