Fully Automatic Paper-Plastic Premium Industrial Packaging Forming Equipment

The HJ-9575 is designed for high-definition 3D paper-plastic packaging that requires sharp edges, smooth surfaces, and consistent wall thickness. Typical end uses include:

Luxury consumer electronics – e.g., smartphone gift boxes, high-end earphone trays, and smartwatch stands.

Cosmetics and perfumes – compact powder cases, perfume outer shells, and lipstick display bases.

Jewelry and watch packaging – internal cushion inserts with recesses for delicate items.

Medical device blister-type protective shells, with strict requirements for dimensional accuracy and cleanliness.

With a platen size of 950×750 mm, the machine can produce large-format trays or multiple smaller cavities per cycle. The 80 mm forming depth accommodates deep-draw designs such as hinged lid boxes or multi-compartment organizer trays.

Dual heating flexibility – Electric heating enables rapid warm-up (≤8 minutes to operating temperature) and precise zonal temperature control (±2°C), while oil heating provides uniform heat distribution for thicker materials (e.g., 1.2-mm PET/paper laminates). One European cosmetics brand using oil heating reduced their reject rate from 6.2% to 1.8% by eliminating cold-spot wrinkles.

40-ton forming pressure – Delivers sharp, high-definition contours even when combining high-grammage paper (up to 600 g/m²) with plastic film. In a trial run for smartwatch trays, the 40T pressure ensured cavity edge radii <0.1 mm and passed 10-point surface gloss tests.

Optimized cycle time (100–120 s) – Includes fully automatic feeding, heating, forming, trimming, and stacking. One Chinese packaging OEM achieved an average 112-second cycle with two-up production, yielding 720 finished trays per 8-hour shift – 22% faster than their previous 150-second hydraulic press.

Large platen size (950×750 mm) – Allows 4-cavity tooling for small gift boxes, reducing energy consumption per part by approximately 18% compared to single-cavity systems.

Servo-controlled depth accuracy – Maintains product height consistency within ±0.15 mm across the 80 mm draw range, verified by laser profilometer – critical for snap-fit closures in high-end packaging.

Our factory implements a four-stage online + offline solution:

A real-case example from a premium audio brand: over 3 months of production, the HJ-9575 maintained a process capability index Cpk of 1.67 on depth dimensions, and the 40-ton pressure system passed a 10,000-cycle endurance test with platen deflection of only 0.02 mm – ensuring long-term repeatability.

Q1: Can the machine handle 100% recycled paper-plastic composites?
A: Yes – but we recommend pre-drying recycled paper (moisture ≤6%) and using oil heating for better thermal inertia. One customer producing eco-friendly gift boxes achieved stable cycles with 40% post-consumer recycled content, though cycle time extended to 118 seconds to compensate for lower thermal conductivity.

Q2: How long does it take to switch between electric heating and oil heating?
A: The heating units are modular and exchangeable – trained technicians can complete the changeover, including flushing and recalibration, within ≤2 hours. We provide quick-connect couplings and pre-calibrated thermocouples to minimize downtime.

Q3: What is the recommended maintenance interval for the 40T hydraulic system?
A: Replace hydraulic oil every 2,000 operating hours; inspect seals and piston rods every 500 hours. According to our field data, three machines running 16 hours/day reported no major hydraulic faults over 18 months when following this schedule.

Q4: How does the machine handle products with undercuts or side draft angles?
A: The forming station supports draft angles up to 3° without special tooling. For steeper undercuts, we offer an optional side pull-out core system (adds 15 seconds cycle time) – validated for watch case inserts with a 7° undercut.

Q5: What is the maximum sheet thickness formable to 80 mm depth without tearing?
A: For paper-plastic laminates, the maximum thickness is 1.5 mm (with oil heating) and 1.2 mm (with electric heating). Thicker sheets require extended preheating – one customer forming 1.4-mm kraft-PET trays achieved a 99.3% yield using a 125-second cycle.

Q6: Does the machine include remote diagnostic capabilities?
A: Yes – all HJ-9575 units are equipped with an IoT gateway. Our service team can monitor temperature, pressure, and cycle trends in real time. In a recent incident, we detected a gradual pressure drop 3 days before failure, sent a repair kit, and avoided unplanned downtime – saving the customer approximately USD 4,200 in lost production.

Q7: How are formed products demolded without deformation?
A: The machine uses a vacuum-assisted stripper plate combined with soft blow-off pulses. The parameters are adjusted per mold set – standard recipe libraries are stored on the HMI, and we provide 5 preset recipes for common material grades.
