EP-HGA.JS-4C114 1000ml 4 Cavities Crafts & Special-Shaped Bottle Blow Molding Machine

Series-Leading 2800 BPH Output

Four simultaneous cavities running at 2800 bottles per hour make the JS-4C114 the highest-throughput model in the crafts and special-shaped blow molding machine series. For compact special-shaped container producers who previously ran two dual-cavity machines in parallel to reach this output level, consolidating into a single four-cavity installation eliminates one complete set of utility connections, maintenance schedules, PLC programs, and operator oversight requirements — a meaningful operational simplification at commercial production volumes.

Four-Cavity Unified PLC Control

All four cavities operate under a single PLC sequence that governs the entire machine simultaneously — oven traversal, clamping, stretch-rod actuation, blowing, and bottle ejection for all four positions in every cycle. Any parameter adjustment made at the operator interface propagates symmetrically to all four cavities, eliminating the inter-cavity process drift that becomes a real quality-management challenge when running multiple separate machines to achieve equivalent throughput.

488-Preform Holder Capacity

The preform holder capacity of 488 units is the largest in the series, supporting the four preform tracks needed to supply all four blow cavities simultaneously without preform starvation at peak cycle speeds. This large-capacity preform handling system also acts as a buffer that smooths out minor upstream feeding inconsistencies, keeping the blowing stations supplied continuously and the 2800 bph output rate sustained across full production shifts.

Compact Container Format Optimized

The 40 mm neck diameter, 94 mm body diameter, and 1000 ml maximum volume define a sweet spot in the compact special-shaped container market — covering the 50–1000 ml range where the majority of craft cosmetics, personal care, craft beverage, and novelty packaging is concentrated. The tighter mechanical envelope compared to large-format models means all four cavities can be fed, blown, and demold-released within a cycle time that sustains 2800 bph without mechanical stress on the clamping or transfer systems.

Multi-Resin Compact Production

PET, PETG, PC, PCTG, and PP resins are all processable on this auto blowing machine in the compact container format range. The four-cavity oven's zone control allows the fine-grained temperature profiling that different resin types and container geometries require, even at 2800 bph cycle speeds. High-clarity PETG for luxury cosmetic vials, chemical-resistant PP for personal care products, and optically neutral PET for craft beverage bottles can all be produced on the same machine installation across different production runs.

Heavy-Duty Four-Cavity Frame

At 6500 kg, the JS-4C114 frame is the heaviest in the series, sized for the cumulative clamping forces generated by four mold sets operating simultaneously. The stress-relieved welded steel construction and precision-ground guide columns maintain all four cavity positions in exact alignment cycle after cycle, ensuring that bottle-to-bottle quality differences between any pair of the four cavities remain within specification across an entire production shift without manual trimming.

Preform Injection Mold

• A split two-piece gate lip assembly maintains the preform's axial center during injection — the starting point for wall-thickness uniformity in the finished compact special-shaped bottle, where any initial offset is visible in the completed container at the high output rates this machine runs.
• Internal cooling circuits are optimized to balance heat extraction across the full preform body, supporting the fast cycle times required to sustain 2800 bph while keeping preform-to-preform temperature consistency within the narrow band the blowing stage needs.
• Forming surfaces are machined from imported 2316 die steel — a grade selected for corrosion resistance and compatibility with precision heat-treatment processes that bring the steel to the hardness appropriate for high-cycle compact container production.
• Core plates, cavity plates, and all structural elements are manufactured from 420 stainless steel, providing reliable resistance to oxidation and chemical exposure throughout the mold's service life in continuous production environments.
• The mold assembly is laid out for rapid access to maintenance points without requiring specialized tools, keeping the planned service intervals as short as possible so machine downtime stays minimal across four-cavity production schedules.
• A standardized interchangeable fitting system allows one mold platform to produce different compact preform designs, reducing tooling inventory and capital cost for facilities running several SKUs on the same JS-4C114 installation.

Blowing Mold

• All four cavity blocks are produced from the same high-grade tool steel specification, selected for its surface hardness and resistance to fatigue at the contact stresses generated by four mold sets operating simultaneously at 2800 bph over multi-year service periods.
• Container profiles for all four cavities are modeled and validated in 3D software before machining, ensuring the geometry is achievable in the compact 94 mm × 250 mm container envelope and that the parting line is positioned to allow clean demold without drag marks on the special-shaped body surfaces.
• A comprehensive range of compact special-shaped silhouettes — cylindrical, oval, multi-faceted, ergonomic grip-waist, and custom contoured — is available from our design library, with new profiles developed to customer specification as a standard service for JS-4C114 purchasers.
• Cooling channels in each of the four cavity blocks are designed to deliver matched heat extraction across all four positions, ensuring that bottle gloss, dimensional release, and cycle timing are consistent between cavities one through four across the full production shift.
• Every metal component across all four blowing-mold sets receives its final dimensions on CNC machining centers, guaranteeing that the parting-line accuracy and cavity geometry are matched across all four positions and that replacement mold sets interchange without requiring realignment.

Four-Track Preform Oven

The oven accommodates four preform tracks running in parallel, with independently controlled lamp zones spanning each track's full height. At 2800 bph cycle speeds, maintaining uniform temperature across all four tracks is the single most critical process variable — any inter-track temperature offset translates directly into quality differences between cavities that accumulate over a production shift and become visible in batch-level cosmetic inspection results.

Four-Cavity Blowing Circuit

The 3000 ltr/min high-pressure air circuit at 30 kg/cm² feeds all four cavities from a common accumulator-buffered manifold. Independent pressure regulators at each cavity position ensure that flow-resistance differences between the four preform positions — caused by minor temperature variations or preform wall-thickness differences — do not create unequal cavity fill across the four blowing stations in each production cycle.

Balanced Quad-Cavity Cooling

Cooling water at 8–10 °C, 5–6 kg/cm², 60 ltr/min is distributed to all four blowing-mold cavities in a manifold arrangement balanced to equalize flow resistance across all four paths. At 2800 bph, even a 5% flow-rate difference between cavities creates a detectable temperature offset that affects both surface gloss consistency and the timing of bottle release from the mold — the most common cause of inter-cavity quality difference in high-speed four-cavity production.

PLC Unified Sequence Control

A single programmable logic controller manages all machine motions — preform loading, oven traversal, four-position clamping, stretch-rod actuation, blowing, and bottle ejection — simultaneously for the entire four-cavity machine. Stored product recipes allow format changeovers by recipe recall rather than manual parameter rebuilding, and all adjustments apply to all four cavities in a single input rather than requiring separate management of four independent process streams.

Cosmetics & Skincare Packaging

Premium serum vials, contoured lotion bottles, multi-faceted foundation dispensers, and ergonomic toner containers in the 50–500 ml range are the primary commercial use case for this bottle blow molding machine. At 2800 bph, cosmetics producers can sustain the high-volume production runs needed to supply large retail accounts in Colombia, South Korea, and Australia while maintaining the surface-quality standards — zero parting-line flash, tight gloss consistency — that premium cosmetics packaging requires.

Personal Care & Household Products

Compact shampoo bottles, conditioner dispensers, hand wash containers, and travel-size personal care packaging in special-shaped formats with ergonomic grip profiles are well matched to the JS-4C114 blow molding machine's 94 mm body diameter and 1000 ml maximum volume. The machine's PP and PETG processing capability covers both transparent and opaque formulations used across personal care product lines that need visual differentiation on shelf without customized packaging formats for each SKU.

Craft & Artisan Beverage Bottles

Compact craft spirit bottles, artisan water vessels, specialty vinegar containers, and single-serve craft beverage packaging are all practical applications for this four-cavity plastic blowing machine. The 40 mm neck diameter accommodates the standard finish sizes used in beverage closures, and the 1000 ml maximum volume covers the full single-serve and standard-retail bottle sizes used in the craft beverage sector across international markets.

Promotional & Gift Packaging

Compact novelty bottles for seasonal promotions, miniature decorative containers for gift sets, and special-shaped branded containers for event and retail merchandising programs are produced at commercially viable volume on the JS-4C114. At 2800 bph, even large promotional campaign volumes — gift set pack-runs requiring hundreds of thousands of identical containers — can be completed within tight production lead times without carrying excessive work-in-progress inventory.

Pharmaceutical & Nutraceutical Packaging

Compact oral liquid containers, dietary supplement bottles, and special-shaped pharmaceutical secondary packaging in PETG or PP are a regulated-market application where the JS-4C114's consistent four-cavity quality performance — identical wall-thickness and dimensional profiles across all four positions — supports container validation requirements. Producers in Brazil, the Netherlands, and Colombia serving pharmaceutical retail and institutional markets use this auto blowing machine where consistent output across every container unit in a batch matters as much as throughput.

Air Compressor

The JS-4C114 blow molding machine's high-pressure air circuit requires 3000 ltr/min at 30 kg/cm² to supply all four blowing cavities simultaneously. Correctly sizing the compressor — accounting for startup transients, pipeline pressure drops, and a safety margin above steady-state demand — is essential for maintaining consistent blowing pressure across all four cavities at 2800 bph.

Kontroler temperatury formy

For PC and PCTG resin production where mold surface temperature control is critical for optical clarity and surface finish, a dedicated mold temperature controller maintains all four blowing-mold cavities at equal, set-point temperatures independent of ambient conditions. At 2800 bph, a small coolant temperature offset between any two of the four cavities becomes visible in batch-level gloss consistency measurements — the mold temperature controller eliminates this variable for temperature-sensitive resin-container combinations.

Bottle Visual Inspection Machine & Chiller

At 2800 bph from four cavities, a downstream visual inspection machine is the only practical way to confirm quality across all four cavity outputs at production speed. In-line inspection checks each container for surface cosmetic defects, incomplete fill, and dimensional non-conformance, flagging individual bad bottles before they reach filling or packaging operations.
