Three cavities operating simultaneously at a 76 mm pitch combines high output with a container size envelope suited to the most common small-format daily chemical bottles. At 3,000 bph, this injection blow molding machine produces 50% more containers per hour than a two-cavity machine at equivalent cavity pitch — without the capital cost and mechanical complexity of a four-cavity platform — making it an efficient scaling step for producers in the 13–18 million bottle per year volume range.

At 2,850 × 1,850 × 2,180 mm and 3,500 kg, the ES-3C76 delivers 3,000 bph from a footprint comparable to many two-cavity machines of larger pitch. For daily chemical manufacturers in Colombia, Peru, and Ecuador whose factory floor space is a limiting constraint, this output-to-footprint ratio is commercially meaningful — the machine scales production without requiring a proportional increase in floor area.

A neck diameter range of 18–38 mm is notably broad for a 76 mm pitch machine. This flexibility supports production of both narrow-neck dropper and spray formats (18–22 mm) and standard daily chemical bottle closures (28–38 mm) on the same platform — reducing the number of dedicated machine configurations required across a diverse daily chemical product portfolio where neck finish varies between SKU families.

With a normal operating draw of 18 kW against a 40 kW maximum, the ES-3C76 runs at well below peak electrical demand during standard production. For manufacturers in Latin American markets where industrial electricity costs represent a significant share of operating expenditure on a bottle blow molding machine line, this ratio produces meaningful per-unit energy savings across the machine's annual production cycle.

International-brand servo motors and reducers govern clamping, stretching, and ejection across all three blow stations simultaneously. Servo-driven control ensures that each station follows the same motion profile within tight tolerances every cycle — a critical requirement on a three-cavity machine where mechanical asymmetry between stations would create detectable cavity-to-cavity variation on finished containers intended for high-speed downstream filling.

This platform is designed to produce complex-geometry daily chemical bottles — oval cross-sections, recessed grip panels, embossed branding areas — in addition to standard round profiles. The 35 kg/cm² fixed blowing pressure and 240 mm stretching stroke provide the mechanical specification needed to fill complex cavity geometries reliably on all three stations without requiring manual pressure adjustments between cavities.

• The die lip is engineered in two separate components that maintain precise axial alignment between the preform and the forming station throughout every injection cycle, preventing coaxiality deviations that produce asymmetric wall distribution during blowing.
• Internal water cooling channels are designed for maximum thermal extraction across the preform profile, reducing conditioning time between cycles and supporting the higher cycle rate of a three-cavity machine without sacrificing preform quality.
• All forming components are machined from imported 2316 die steel with complete heat treatment, providing the corrosion resistance and dimensional stability needed for continuous three-shift operation at three-cavity cycle speeds.
• Core plates, cavity plates, and structural parts are built from 420 stainless steel, selected for its reliable resistance to the chemical and thermal environment inside the injection station.
• Modular construction keeps scheduled maintenance practical within planned production downtime windows, without requiring specialised tooling or extended disassembly.
• Standardised interchangeable die fittings reduce spare parts inventory requirements across the three mold positions and multiple mold sets.
• Each mold set can accommodate more than one preform geometry, reducing total tooling investment for manufacturers running multiple daily chemical container specifications on the same machine.

• Cavity bodies are produced from high-grade tool steel with hardness and dimensional stability specified for the thermal cycling demands of three-cavity IBM production on daily chemical bottle formats.
• Bottle cavity geometry is generated using advanced 3D design software, ensuring accurate profiles on both standard round daily chemical bottles and the complex asymmetric shapes common in branded personal care packaging.
• An extensive catalogue of established bottle designs is available for standard daily chemical formats; custom cavity development is also supported for brand-specific container profiles across all three positions.
• Internal water cooling channels are distributed across the full cavity surface for balanced heat extraction, preventing the localised hot spots that cause thin walls or surface defects on small-format containers produced at three-cavity speeds.
• All metal structural components are machined on CNC equipment, delivering the dimensional tolerances required for consistent performance across all three blow stations throughout extended production runs.

Containers up to 700 ml with body diameters to 68 mm and heights to 240 mm are within this machine's envelope. This covers most 200–700 ml shampoo, liquid soap, and daily chemical bottle profiles in the compact-to-mid-size range that dominate personal care retail in Colombian and Andean markets. Containers above 700 ml or above 68 mm body diameter require a larger-pitch machine.

At 3,000 bph theoretical output running two 8-hour shifts at 90% uptime, the ES-3C76 produces approximately 13–15 million bottles per year. This is the appropriate volume range for mid-scale daily chemical operations or contract packaging businesses that have outgrown two-cavity capacity but cannot justify the tooling investment of a four-cavity configuration at their current volume level.

The 18–38 mm neck diameter range makes this machine unusually flexible for a 76 mm pitch platform. If your product portfolio includes both spray-top personal care formats (18–24 mm) and standard cap daily chemical bottles (28–38 mm), the ES-3C76 covers both without requiring separate machine configurations for different neck finish families.

The machine needs 35 kg/cm² blowing air at 2,400 ltr/min on the high-pressure circuit, 7 kg/cm² at 1,500 ltr/min on the low-pressure circuit, and cooling water at 8–12°C and 30 ltr/min. In tropical climates across Colombia and neighbouring countries, an industrial chiller is required for the cooling water supply year-round. Confirm that your facility's compressor capacity covers the combined high-pressure demand before ordering.

The 300–700 ml shampoo and body wash bottle formats that account for the majority of hair care retail volume in Colombia and the Andean region sit comfortably within the ES-3C76 container envelope. At 3,000 bph, the machine sustains the output level needed to supply major retail chains across multiple distribution centres in parallel without requiring second-shift overtime on high-demand SKUs.

Pump-top liquid hand soap in 300–500 ml formats is one of the highest-volume daily chemical categories in institutional supply chains — hotels, hospitals, commercial buildings, and schools across Colombia's main cities. The 38 mm maximum neck diameter on this machine accommodates the pump-top neck finishes used on these products, and the output rate supports the volume requirements of institutional supply contracts.

Spray toner and essence bottles in clear PETG or PET in the 100–300 ml range use narrow neck finishes in the 18–24 mm range — well within the ES-3C76's neck diameter capability. Brands supplying prestige skincare to Colombian pharmacies and beauty retailers increasingly favour three-cavity output to maintain adequate stock levels while keeping machine capital investment below four-cavity thresholds.

Hair spray, leave-in conditioner spray, and body mist bottles with 18–22 mm narrow neck finishes benefit from the narrow neck range this machine supports. The container height of up to 240 mm covers the taller spray bottle formats common in premium personal care lines, and PETG resin compatibility provides the glass-like clarity that brand-owners in this segment typically require for retail shelf appeal.

Compact household cleaner, multi-surface spray concentrate, and bathroom cleaner formats in the 300–600 ml range that use standard 28–32 mm neck closures are a practical secondary application for this machine alongside its primary personal care output role. Manufacturers running mixed daily chemical and personal care product portfolios can use the ES-3C76 across multiple product categories with tooling changes rather than needing separate dedicated machines.

Supplying 35 kg/cm² at 2,400 ltr/min to the high-pressure blowing circuit across three simultaneous cavities requires a compressor sized specifically to this combined demand. Our matched oil-free compressor systems are pre-specified for the ES-3C76 combined air consumption, preventing both pressure drop during peak blowing cycles and oil contamination that degrades container surface quality.

On a three-cavity machine where each station must produce dimensionally identical containers, mold temperature uniformity across all three cavity positions is essential. A temperature controller maintains both injection and blow mold surfaces within a defined operating range, preventing the gradual thermal drift between stations that causes detectable variation in wall thickness or surface clarity over extended production shifts.

At 3,000 bph output across three cavities, automated downstream inspection is the practical quality assurance method. A visual inspection system detects dimensional deviations and wall defects at the conveyor exit before containers reach filling lines — separating any out-of-spec containers before they enter production inventory, which is a quality control requirement for daily chemical manufacturers supplying regulated retail and institutional markets in Colombia.

Cooling water at 8–12°C and 30 ltr/min is required for stable mold performance across all three cavities. In humid tropical and subtropical climates across Colombia, Venezuela, and coastal Ecuador, only a dedicated industrial chiller can reliably maintain the 8–12°C supply water temperature throughout the year. Our matched chiller units are pre-configured to the ES-3C76 cooling circuit specifications.
