EP-HGA.P.FS-2C150 (2500ml) 2 Cavities Crafts & Special-Shaped Bottle Blow Molding Machine

Industry-Leading 1800 BPH Output

With a theoretical output of 1800 bottles per hour from dual cavities, this blow molding machine delivers throughput that makes commercial-scale special-shaped bottle production economically viable. For crafts and gift packaging producers who previously relied on single-cavity equipment at 700–900 bph, the 2C150 can effectively double output without adding a second machine installation, freeing floor space and reducing utility costs per bottle produced.

2500 ml Special-Shaped Container Capability

The 2500 ml maximum volume combined with a 130 mm body diameter and 250 mm container height opens the machine to a broad range of craft and specialty formats — from compact 100 ml novelty bottles to 2-litre promotional and gift containers. The 190 mm clamping stroke and 440 mm mold-open distance are specifically dimensioned to accommodate the varied parting-line geometries that special-shaped containers present at demold, preventing the edge distortion that can occur when the mold-open clearance is insufficient for complex body profiles.

CNC-Precision Special-Shaped Mold Cavity

Reproducing complex non-standard container geometry accurately at 1800 bph demands mold cavities machined to tolerances tighter than those needed for plain cylindrical containers. Every blowing mold supplied with this machine is processed entirely on CNC machining centers, with cavity geometry first validated in 3D modeling software before any steel is cut. This workflow eliminates the geometric drift between the design intent and the produced bottle that manual cavity finishing inevitably introduces.

Broad Resin Range for Diverse Aesthetics

Special-shaped bottles for the gift and cosmetics segments demand diverse optical and tactile properties — transparent PETG for luxury serums, opaque PP for lifestyle products, high-clarity PC for premium spirits. This plastic blow molding machine processes all five resin families (PET, PETG, PC, PCTG, PP) within a single parameter envelope, allowing the same machine to serve multiple product lines across a production schedule rather than requiring dedicated equipment for each resin type.

35 kg/cm² High-Pressure Blowing for Thin Walls

Special-shaped containers often feature thin-wall sections that must be fully formed in a single blow cycle to achieve the surface definition that makes the design commercially attractive. The machine's 35 kg/cm² blowing pressure — supported by 1200 ltr/min high-pressure air supply — delivers the pneumatic force needed to fill complex cavity geometry completely before the resin cools below its forming temperature. Inadequate pressure is one of the primary causes of incomplete fill in contoured and relief-textured container designs.

Patented Structural Reliability

Like all machines in our blow molding machine series, the 2C150 incorporates patented innovations in clamping, oven architecture, and process control subsystems developed over more than two decades of dedicated R&D. These patents represent engineering improvements that deliver measurable production benefits — reduced cycle variance, extended mold service intervals, and lower unplanned downtime — not simply design registrations on standard industry configurations.

Preform Injection Mold

• A two-component gate lip assembly ensures the preform is formed on a perfectly maintained central axis, providing the symmetrical wall distribution that special-shaped containers depend on for accurate body geometry during blow expansion.
• The cooling circuit inside the mold is designed to remove heat uniformly from the full preform surface, allowing consistent crystallinity and temperature across the preform's circumference before it enters the oven stage.
• Forming contact surfaces are machined from imported 2316 die steel, a grade chosen for its corrosion resistance and thermal stability during the heat-treatment process that brings it to operating hardness.
• Core plates, cavity plates, and frame elements are manufactured from 420 stainless steel throughout, providing resistance to moisture-related corrosion during high-humidity production environments and extended shutdown periods.
• The mold layout is designed for tool-free routine maintenance access, keeping planned service intervals short and avoiding the need for specialized workshop support on-site.
• Standardized interchangeable component geometry allows one mold base to serve multiple preform designs — reducing tooling procurement and storage costs for production lines running several container formats.

Blowing Mold

• High-grade tool steel is specified for all blowing-cavity blocks, providing the surface hardness and fatigue resistance needed to sustain geometrically complex cavity surfaces through millions of production cycles without dimensional drift.
• Every container profile — regardless of its complexity — is modeled and validated in advanced 3D software before any machining is initiated, ensuring the physical mold geometry precisely matches the approved design file and that undercuts and parting-line placement are optimized for clean, defect-free demold.
• Our mold design library covers a wide range of container silhouettes, from standard cylindrical to complex multi-faceted and sculptural forms, with custom profiles developed to customer specification as a standard service.
• Cooling channels are routed through the cavity block in patterns calculated to deliver uniform extraction across all surface zones — including the asymmetric areas that special-shaped containers create — preventing localized heat retention that would produce haze or surface deformation.
• All metal components receive their final dimensions from CNC machining centers, ensuring that the parting-line accuracy and cavity surface finish are consistent across both cavity positions in the dual-cavity configuration.

PLC Process Control

A programmable logic controller manages all machine sequences — mold open/close, preform loading, oven traversal, stretch-rod actuation, blowing, and bottle ejection — for both cavities simultaneously. Saved product recipes allow fast changeovers between container formats without rebuilding parameters, and unified control means any tuning adjustment applies symmetrically to both cavities in a single input rather than requiring separate adjustments at two machines.

Zoned Infrared Oven

Independent zone control across the full oven length is essential for special-shaped bottle production. Different sections of the preform must reach different temperatures to achieve the varying stretch ratios that a complex container geometry demands. The oven's zone configuration can be tuned per-preform-height-position, giving operators the control resolution needed to produce asymmetric shoulder profiles, grip waists, and textured body sections without wall-thickness compromise.

High-Pressure Blowing System

Operating at 35 kg/cm² with 1200 ltr/min high-pressure air capacity, the blowing circuit is proportionally regulated with an accumulator buffer to absorb demand transients at the start of each blow cycle. This stabilized delivery is particularly important for special-shaped containers because cavity geometry creates non-uniform flow resistance during inflation — a pressure spike at the wrong moment can force material through an area of minimum resistance before the full cavity shape is formed.

Balanced Dual-Cavity Cooling

Cooling water at 8–10 °C, 5–6 kg/cm², 30 ltr/min is distributed in a balanced circuit to both blowing-mold cavities. For high-speed special-shaped production at 1800 bph, maintaining matched cooling rates between the two cavities is not optional — an offset as small as 1–2 °C between cavity positions will produce detectably different surface gloss and dimensional release characteristics between the two bottle outputs per cycle.

Gift & Promotional Packaging

Seasonal gift bottles, promotional spirits containers, and novelty packaging for retail displays require complex silhouettes that standard round-body blow molding equipment cannot produce faithfully. The 2C150 Blow Molding Machine's CNC-machined mold cavities and precise blowing control reproduce sculptural container geometries accurately at 1800 bph — making commercial-volume gift and promotional packaging production economically viable for brands in Colombia, the Netherlands, South Korea, and global retail markets.

Premium Cosmetics Containers

High-end serum bottles, lotion dispensers, and fragrance containers with sculpted bodies and textured grip zones are a primary use case for this auto blowing machine. Cosmetics brands in premium segments require zero visible parting-line flash, tight surface gloss consistency across a production batch, and dimensional accuracy in thread finish and cap seating. The 2C150's matched CNC-machined cavity pairs deliver these requirements across both cavities simultaneously at production speed.

Craft & Artisan Beverage Bottles

Craft spirits, artisan water, specialty vinegar, and premium condiment brands increasingly use special-shaped containers as a core brand differentiation strategy. This bottle blow molding machine's ability to produce up to 2500 ml in non-standard silhouettes — with volumes spanning from single-serve 200 ml to large-format 2-litre formats — covers the full range of craft beverage container requirements that the premium food and drink sector currently demands from a specialized plastic blowing machine.

Toys, Collectibles & Novelty Items

Character-shaped bottles, figural collectible containers, and toy-adjacent novelty products in PET or PETG are well within the 2C150 Blow Molding Machine's production capability. The machine's ability to process transparent and tinted PETG at high clarity produces the visual quality that collectible and premium toy packaging requires, while the dual-cavity output at 1800 bph makes production of licensed character containers commercially feasible for mid-tier toy and gift companies globally.

Personal Care & Wellness Products

Ergonomically shaped shampoo bottles, grip-waist body wash containers, and custom-silhouette skincare packaging for professional salon brands and retail chains are a practical commercial application for this blow molding machine. The 100 mm neck diameter range accommodates wide-opening dispensing neck finishes, while the 130 mm body diameter supports the broader body profiles typical in personal care packaging that is designed to sit visibly on retail shelves.

Air Compressor

The 2C150's blowing circuit operates at 35 kg/cm² with 1200 ltr/min high-pressure air consumption. A correctly sized compressor with an appropriate safety margin above this peak demand is essential to prevent pressure drops during the blowing phase — the most common cause of incomplete cavity fill in complex special-shaped containers. For cosmetics and food-contact applications, oil-free compressor models ensure that air quality meets the purity requirements of the product categories served.

ตัวควบคุมอุณหภูมิแม่พิมพ์

For PC and PCTG resins used in premium special-shaped containers, and in production environments where ambient temperature fluctuations affect cooling circuit performance, a mold temperature controller stabilizes coolant supply to both blowing-mold cavities at a set point maintained to ±1 °C. At 1800 bph, even small coolant temperature offsets between the two cavities produce detectable gloss and dimensional differences between the bottles produced from each position in the same cycle.

Bottle Visual Inspection Machine & Chiller

At 1800 bph output from two cavities, in-line visual inspection is the only practical way to detect cosmetic or dimensional defects before they reach downstream filling or packaging operations. An automated inspection machine positioned immediately after the blow molding machine output conveys checks every container for surface imperfections, incomplete fill areas, and geometric non-conformance at line speed. Combined with a dedicated chiller maintaining the 8–10 °C cooling water supply the 2C150 requires, these auxiliaries complete the production cell.
