EP-HGA.ES-2C114.3 Lotion Bottle & Toner Bottle Blow Molding Machine

Servo-Driven Precision

International-brand servo motors and precision gearboxes keep clamping force and stretching rod movements tightly repeatable, eliminating variance that causes wall-thickness defects in cosmetic bottle production. The result is a consistent finish cycle after cycle, shift after shift — critical for luxury lotion and toner packaging lines where clarity and uniformity are non-negotiable quality criteria.

Two-Stage Flexibility

Because preform production is decoupled from blowing in this two-step blow molding configuration, operators can switch bottle formats with minimal downtime, running standard preform stock while only changing the blowing mold. This architecture is particularly valued by contract packaging plants serving multiple cosmetic brand clients with differing bottle specifications and seasonal SKU changes.

High-Difficulty Bottle Capability

This plastic blow molding machine is specifically optimized for complex geometry bottles — bottles with asymmetric shoulders, long narrow necks, and multi-faceted sidewalls that challenge generic PET blow molding machine designs. The 400 mm stretching stroke and 35 kg/cm² blowing pressure give it the mechanical authority to fully expand demanding mold geometries that simpler machines routinely fail to fill correctly.

Energy-Efficient Operation

Normal running power of 16 kW against a maximum installed capacity of 50 kW reflects genuine energy management — the servo system only draws current proportional to actual mechanical load. Compared with older hydraulic-based bottle molding machines of similar output, this architecture typically delivers substantial reductions in kilowatt-hour consumption per thousand bottles produced, lowering operating cost throughout the service life of the machine.

Preform Injection Mold

The die lip uses a split two-part design that maintains precise coaxiality throughout preform formation — a direct contributor to uniform wall thickness in the finished bottle. The internal cooling channels are routed to maximize heat transfer from the preform core outward, shortening cycle time without compromising dimensional stability. Forming components are machined from imported 2316 die steel, which carries inherent corrosion resistance after heat treatment. Core plates and cavity plates use 420 stainless steel throughout, ensuring long-term resistance to the water-based cooling environment. The mold architecture permits a single toolset to produce more than one preform specification, giving operations teams the flexibility to adapt output without a full tooling investment.

Blowing Mold

Blowing molds are fabricated from premium-grade steel selected for thermal conductivity and surface hardness. Each bottle profile is modeled in advanced 3D CAD software before a single chip is cut, allowing virtual validation of parting line placement, vent positioning, and cavity fill dynamics. A wide library of pre-engineered bottle silhouettes is available for customers who need fast project startup, while fully custom profiles are accommodated for brands with proprietary packaging IP. Water cooling passages are laid out to cool every bottle zone at comparable rates, preventing localized shrinkage that distorts label panels or base geometry. All metallic mold components are finished on CNC machining centers to ensure cavity-to-cavity consistency and straightforward field maintenance.

Lotion & Toner Bottles

Precision blowing of skincare containers with tall profiles, faceted panels, and pump-neck finishes. The machine handles the demanding wall distribution requirements of prestige skincare packaging.

Shampoo & Conditioner Bottles

High-volume runs of personal hair care containers in 200 ml to 1,000 ml formats, including ergonomic grip profiles that require controlled material distribution across the grip zone.

Body Wash & Liquid Soap

Production of household cleaning and personal wash containers where high clarity PET or color-tinted PETG resins are required to align with brand aesthetics and shelf appeal.

Perfume & Specialty Cosmetics

This plastic blowing machine accommodates special-shaped bottles — asymmetric forms, ribbed textures, and decorative profiles — that define premium fragrance and specialty cosmetic categories in retail markets globally.

Opakowania farmaceutyczne

Food-contact and pharma-grade PET containers for oral liquid medications, nutritional supplements, and healthcare products where dimensional accuracy and material purity are regulatory requirements.

Air Compressor

High-pressure oil-free air compressors sized to meet the 35 kg/cm² blowing pressure requirement and 1,000 ltr/min high-pressure air consumption of this machine. System pressure compatibility is verified before delivery.

Kontroler temperatury formy

Dedicated water-type mold temperature controllers maintain blowing mold temperature within the 8–12 °C operating range specified for this machine, directly supporting cycle repeatability and bottle quality stability across long production runs.

Bottle Visual Inspection Machine

Inline vision inspection systems integrated immediately downstream of the auto blowing machine to detect wall defects, contamination, and dimensional non-conformances before bottles enter the filling line — essential for pharmaceutical and prestige cosmetic applications.

Chiller & Cooling Water System

Industrial chillers supplying 30 ltr/min at 8–12 °C to the cooling water circuit. Stable chilled water supply is one of the most critical utility parameters for achieving consistent bottle weight and wall thickness in this pet blow molding machine.
