EP-HGA.ES-4C150 Daily Chemical Bottle Blow Molder
Он EP-HGA.ES-4C150 is a high-output blow molding machine purpose-built for daily chemical and cosmetic container production. Equipped with internationally sourced servo motors, precision gear reducers, and a fully integrated electrical control architecture, this platform sets a reliable standard for large-format bottle manufacturing in PET and PETG materials. Its 4-cavity layout supports a theoretical output of 4000 bottles per hour, and the extended bottle mold-close distance of 150 mm opens the door to wider-body containers that most comparably priced bottle blow molding machines simply cannot accommodate.
Built around a two-step blow molding process, the ES-4C150 separates preform conditioning from the blowing stage, giving operators granular control over reheating uniformity, stretch rod motion, and blowing pressure sequencing. This flexibility translates into consistent wall thickness, high optical clarity, and a low reject rate across diverse container geometries — from standard oval dispensers to asymmetric shaped bottles with demanding dimensional requirements.

Why the ES-4C150 Stands Out in Its Class
Within the daily chemical packaging industry, container volumes above 1 litre represent a fast-growing segment driven by bulk personal care refills and household cleaning products. The ES-4C150 addresses this segment head-on: its 2500 ml maximum container capacity and 130 mm body diameter capability make it one of the more capable two stage blow molding machines available at this output tier. Producers who have historically required a larger, heavier plastic blow molding machine to handle jumbo daily chemical containers can now achieve comparable results from a platform with a much smaller factory footprint — the 6200 × 2150 × 2050 mm envelope fits cleanly into most mid-sized production bays.
The servo drive system underpinning this fully automatic blow moulding machine governs the clamping, stretching, and ejection sequences with sub-millimeter repeatability. At 4000 bph theoretical output across 4 cavities, the per-cavity cycle time is tight enough to match modern high-speed filling lines without creating a bottlenecking upstream. Because the two step blow molding approach separates preform production from bottle blowing, the oven reheating zone can be tuned independently for each preform weight and wall profile, making material transitions between product SKUs far smoother than integrated single-stage systems allow.
Aftersales reliability matters as much as headline performance. All wear components — guide rods, clamping platens, neck mold carriers — are engineered to standard dimensions, stocked in our spare parts warehouse, and can reach customers in Colombia, Australia, Brazil, and the Netherlands within predictable lead times. For production managers evaluating blow molding machine for sale options across multiple suppliers, this logistical depth is a differentiating factor that often proves its value long after the initial commissioning visit.
Core Advantages of Blow Molding Machine
Large-Format Container Range
At up to 2500 ml capacity and 130 mm body diameter, this bottle blow molding machine handles bulk shampoo, conditioner, laundry liquid, and cleaning agent containers that 4-cavity platforms in narrower configurations cannot reach. A single mold set can cover 500 ml, 1000 ml, and 2000 ml variants of the same bottle family with minimal change-over time, giving contract packagers the production flexibility they need to serve multiple retail accounts from one machine.
Precision Servo Architecture
Internationally sourced servo motors drive both the stretching rod assembly and the clamping mechanism, achieving positional repeatability that conventional hydraulic-only systems cannot match. This translates directly into uniform biaxial orientation of the PET molecular chains, which is the physical basis for the superior top-load strength and drop resistance that premium blow molding pet bottles require. Servo-driven systems also respond faster to process corrections, reducing the number of off-specification bottles produced during warm-up and during material transitions.
High-Pressure Blowing Capability
With a blowing pressure rating of 30 kg/cm² and a high-pressure air consumption of 6500 ltr/min, the ES-4C150 provides the pneumatic force necessary to fully expand large-volume PETG containers against complex mold geometries. Maintaining adequate pressure at the cavity wall during the final forming phase is what locks in the container's finished dimensions — a parameter where under-specified auto blowing machines tend to produce undersized or wrinkled containers, particularly in the shoulder and base regions of wide-body bottles.
Energy Management
The 78 kW maximum heating power and 32 kW electrical heating power ratings, combined with the servo drive's load-following energy consumption pattern, give this pet blow molding machine a favorable energy-per-bottle figure for its output class. Production facilities in Colombia and across Latin America, where utility costs represent an increasingly significant share of operating expenses, benefit from the reduced idle draw that servo architecture delivers compared to fixed-speed motor configurations used in older generation equipment.
Engineering & Control System
The structural backbone of this injection blow molding machine uses heavy-section welded steel platens and guide columns machined to tight parallelism tolerances, ensuring that clamping force distribution is even across all four mold cavities at every cycle. Inconsistent clamping — a common failure mode in lower-cost blowing molding machines — produces flash lines and parting seam defects that add manual finishing labor and increase material waste per saleable unit.
The PLC-based control system provides a touchscreen interface for setting and monitoring all process variables: oven zone temperatures, stretching rod timing, blowing pressure curve, cooling duration, and ejection sequence. Each parameter can be stored as a named recipe, enabling rapid reloading of proven settings when switching between established product molds. The system also maintains a cycle-by-cycle data log that production supervisors can review for process drift analysis — a capability that supports quality management systems aligned with ISO and GMP requirements common in pharmaceutical and cosmetic packaging facilities.
Maintenance access is a practical consideration that is often overlooked during procurement. The ES-4C150 design locates all routine service points — lamp assemblies, neck mold carriers, air fittings, and lubrication points — at accessible heights without requiring removal of major sub-assemblies. This design philosophy extends planned maintenance intervals and reduces the unscheduled downtime that erodes overall equipment effectiveness on high-output plastic blowing machine lines.
Mold Engineering
Preform Injection Mold
The die-lip structure is divided into two precision-fitted components, a configuration that locks in axial concentricity during the preform forming stage. Any deviation from true concentricity at this point propagates through to the finished bottle as uneven wall thickness — so getting this detail right at the mold engineering level eliminates an entire class of downstream defects without requiring process compensation.
Cooling channels are routed to maximize surface contact with the preform body, shortening the thermal cycle and supporting faster production cadence. The cavity surfaces and core elements are produced from imported 2316 die steel, which combines rust resistance with the hardness retention needed for sustained high-cycle operation. Structural plates — core plate and cavity plate — are manufactured from 420 stainless steel, providing long-term corrosion resistance in the humid injection environment. Standardized component dimensions across the mold range mean that a single preform mold can be configured to produce preforms for multiple neck diameters, and maintenance tasks can be completed by in-house technicians using standard workshop tooling.
Blowing Mold
The blowing mold cavity begins as a 3D CAD model developed with specialist bottle design software, allowing the engineering team to validate draft angles, parting line placement, and material distribution before committing to tooling. This digital-first process reduces the number of physical iterations needed to reach approved production samples, which shortens the total time from design brief to first shipment.
Premium tool steel is selected for every mold component based on hardness, thermal conductivity, and machinability — properties that directly affect cycle time and container surface finish. All cavity surfaces and mechanical components are finished on CNC machining centers, holding tolerances that manual machining cannot achieve consistently. The internal cooling circuits are engineered to deliver uniform chilling across the container footprint, preventing hot spots that cause localized thinning or distortion in wide-body containers. A varied portfolio of bottle shapes is available from our existing library, and full custom development is offered for brands requiring a proprietary container design.
How to Select the Right Blow Molding Machine for Your Requirements
The most common error in specifying a bottle blow molding machine is anchoring the decision on theoretical output alone. Theoretical figures assume 100% uptime, zero changeover time, and perfect preform quality — conditions that rarely hold in practice. A more reliable approach is to calculate the effective output at your target efficiency rate (typically 85–90% for a well-maintained automatic pet blowing machine) and size the machine to cover that figure plus a growth buffer of 15–20%.
The ES-4C150 Blow Molding Machine's 2500 ml capacity maximum makes it the appropriate choice when your product portfolio includes containers above 1000 ml — bulk dispensers, large family-size bottles, or institutional packaging formats. If your entire range sits below 1000 ml, a narrower-specification model may reduce your capital cost without sacrificing any useful capability. Conversely, if you anticipate significant future expansion into larger formats, specifying the ES-4C150 now avoids a machine replacement cycle within three to five years.
Material compatibility is another factor. Both PET and PETG run well on this platform, but if your roadmap includes PP or PC containers, a different machine series — including our extrusion blow molding machine range — should be evaluated alongside the stretch blow options. Matching the машина для литья под давлением с растяжением и выдувным формованием type to the material and container geometry requirements is the foundation of a reliable, cost-effective production line, and our engineering team can support this analysis for producers in Colombia, South Korea, the Netherlands, and other target markets.

Compatible Auxiliary Equipment
A complete production line built around this blow molding machine requires matched peripheral systems. We supply the following auxiliary equipment, each engineered to integrate with the ES-4C150 Blow Molding Machine from day one — giving you a single-source solution for the entire production system:
Oil-Free Air Compressor
High-pressure oil-free air supply units designed for the demanding pressure and volume requirements of stretch blow molding machines. The oil-free design eliminates hydrocarbon contamination from the blowing air stream — a non-negotiable requirement for food, pharmaceutical, and premium cosmetics packaging.
Регулятор температуры пресс-формы
Precision temperature control units hold mold surface temperature within a tight ±1°C band, which is especially important for large-volume containers where the extended mold contact time amplifies the effect of any thermal variation. Stable mold temperature is one of the most reliable levers for improving container clarity and reducing sink defects.
Bottle Visual Inspection Machine
Camera-based automated inspection systems screen every container for dimensional non-conformance, surface contamination, and wall defects at line speed. Placing a visual inspection station immediately downstream of the auto blowing machine transforms quality control from a statistical sampling exercise into a 100% coverage process.
