HS-C Series Automatic Small Cardboard Box Folding and Gluing Machine

The HS-C Series is a fully automatic, high-speed automatic small cardboard box folding and gluing machine with a PLC touchscreen control system, designed specifically for packaging manufacturers that process small, varied formats — including boxes for ecommerce, cosmetics, pharmaceuticals and other applications where the minimum box dimensions are critical. With a minimum folding spacing of just 210 mm and minimum box front dimensions of 130 mm and back of 80 mm, this automatic small cardboard box folding and gluing machine covers formats that other folder-gluers in the family cannot process.

Compared with the HS-A and HS-B series — which have a minimum spacing of 350 mm and minimum formats of 140–150 mm — the HS-C Series is designed explicitly for small and medium boxes, with a servo gluing head electrically adjustable in 4 directions and a PLC system with data entry without stopping the machine. It is the ideal solution for plants that simultaneously produce diverse formats and need fast, precise changeover between jobs, with no downtime for manual adjustment.

Key advantages of the HS-C Series automatic small cardboard box folding and gluing machine

• Minimum folding spacing 210 mm — suitable for small and ecommerce boxes – compared with 350 mm on the HS-A and HS-B series, the HS-C Series automatic small cardboard box folding and gluing machine can process significantly smaller formats, covering standard boxes for ecommerce, cosmetics and pharmaceuticals that are not compatible with other models in the family.

• PLC touchscreen control with data entry without stopping the machine – the PLC system with touchscreen allows production parameters to be changed in real time, without stopping the line; fast and reliable response, with job storage and recall for quick format changeover.

• Servo gluing head with electric adjustment in 4 directions – the gluing head can be electrically adjusted left-right and front-back, with automatic data setting and a one-click adjustment function responding across the whole machine — eliminating repetitive manual adjustments and reducing format-change times to a minimum.

• Continuous automatic gluing without breaks – the automatic glue circulation system with coated stainless-steel wheels (resistant to corrosion and wear) applies the glue uniformly along the entire length of the flap, with no gluing gaps caused by different adhesive viscosities.

• Electric vacuum cleaning brush at the gluing section – effectively reduces the imprint of the cut edges at the gluing port, improving the visual quality of the finished box and eliminating appearance defects caused by adhesive residue at the edges.

• Soft pressure paper with silicone elastic and deviation correction – effectively corrects the scissor-difference phenomenon of full flaps, ensuring uniform and symmetric folding even on board with dimensional deviations or thickness variations.

• Independent variable-frequency adjustment on the folding section – the folding speed can be adjusted up and down independently of the main line speed, effectively adjusting the left-right synchronization for smoother production on small formats with frequent changes.

• Special guide for small ecommerce boxes (optional) – the special inlet guide ensures smooth entry of small packaging boxes into the folding section, preventing jams and the alignment errors common when processing formats under 300 mm.

Technical specifications of the HS-C Series automatic small cardboard box folding and gluing machine

The 3 models of the HS-C Series automatic small cardboard box folding and gluing machine

920C — maximum speed for small boxes in intensive production

The 920C model of the automatic small cardboard box folding and gluing machine reaches 280 pcs/min on formats between 130 mm front and 80 mm back, with a minimum folding spacing of 210 mm. It is the choice for ecommerce and fulfillment plants that process high volumes of small boxes with frequent format changes, where speed and accuracy of automatic adjustment are critical factors.

924C — sustained production at 250 pcs/min for varied formats

At 250 pcs/min, the 924C model of the automatic small cardboard box folding and gluing machine offers high productivity across a wide range of small and medium formats. It is recommended for manufacturers of cosmetic, pharmaceutical and small-size food packaging, where the variety of formats and gluing quality are as important as production speed.

1224C — extended width for small-medium formats in width

The 1224C model extends the working width to 1224 mm, maintaining the same minimum format dimensions (front 130 mm, back 80 mm). The 1224C automatic small cardboard box folding and gluing machine is the solution for manufacturers that simultaneously process boxes that are small but wider, typical of packaging for household products or small industrial items.

Why the HS-C Series over the HS-A and HS-B — a selection guide

The HS-A and HS-B series are folder-gluer machines optimized for medium and large formats, with a minimum folding spacing of 350 mm and minimum box front/back dimensions of 140–150 mm. The HS-C Series automatic small cardboard box folding and gluing machine covers a completely different segment: a minimum spacing of 210 mm and front/back formats from 130 mm / 80 mm — boxes that the A and B series cannot physically process.

The HS-C Series is the choice when the order includes boxes under 350 mm folding spacing, when the plant produces for ecommerce with highly varied formats and frequent job changes, or when PLC touchscreen control with automatic servo gluing-head adjustment is an operational requirement. UZINEX provides free technical consultancy to identify the right series based on the customer's format portfolio.

Applications and industries for the HS-C Series automatic small cardboard box folding and gluing machine

The HS-C Series automatic small cardboard box folding and gluing machine is intended primarily for manufacturers of packaging for ecommerce and fulfillment, where the range of box sizes is extremely varied and orders change frequently. The optional special guide for small ecommerce boxes and the PLC system with format change without stopping are features designed explicitly for this sector.

The cosmetic and pharmaceutical industry uses this automatic small cardboard box folding and gluing machine for small-size boxes with strict gluing-quality requirements and an impeccable visual appearance of the finished box. The electric vacuum cleaning brush and the silicone-elastic pressure paper eliminate the appearance defects common on small formats processed at high speeds.

Manufacturers of individually packaged food products, medicines, personal care products and other fast-moving consumer goods find in the HS-C Series an automatic small cardboard box folding and gluing machine capable of processing different formats simultaneously within the same production shift, with fast automatic adjustment and no waste caused by job changes.

How the HS-C Series automatic small cardboard box folding and gluing machine works

1. Feeding with PLC control and variable frequency – the small pre-die-cut blanks are fed into the automatic small cardboard box folding and gluing machine by the imported belt transmission system; the locking carriage and the paper pressing roller are electrically adjustable in distance directly from the PLC touchscreen panel.

2. Automatic servo gluing-head adjustment – when changing format, the servo gluing head repositions electrically in 4 directions (left-right and front-back) with a single click or through automatic adjustment synchronized with the new job parameters, with no manual intervention.

3. Glue application with automatic circulation – the automatic glue circulation system with coated stainless-steel wheels applies the adhesive uniformly along the entire length of the flap, with no gaps or over-dosing, regardless of the viscosity of the adhesive used.

4. Edge cleaning at the gluing port – the electric vacuum brush cleans the cut edges of the flap before adhesive application, preventing edge imprint and ensuring an impeccable visual appearance of the finished box.

5. Folding with independent left-right synchronization – the independent variable-frequency adjustment on the folding section adjusts the left-right synchronization, with the soft silicone-elastic pressure paper automatically correcting flap deviations.

6. General system correction and final guidance – the general correction system, electrically movable horizontally, corrects residual board deviations; the special guide for small boxes (optional) ensures smooth entry into the collection section without jams.

7. Automatic collection, counting and stacking – the pneumatic clamping mechanism with automatic counting stacks the finished boxes according to the set quantity; the pushing force and the stack output with independent variable frequency are adjusted according to the order volume for maximum packaging efficiency.

Frequently asked questions about the HS-C Series automatic small cardboard box folding and gluing machine

What is the minimum box size that the HS-C Series machine can process?

The HS-C Series automatic small cardboard box folding and gluing machine processes boxes with a front of at least 130 mm, a back of at least 80 mm and a minimum folding spacing of 210 mm — significantly below the limit of the HS-A series (140/140 mm, 350 mm spacing) and the HS-B series (150/150 mm, 350 mm spacing). The practical difference: the HS-C can produce "compact pack" ecommerce boxes (boxes for small vials, blisters, ampoules) and standard pharma boxes that the HS-A and HS-B cannot physically fold. This capability makes it the only machine in the UZINEX family suitable for small ecommerce boxes and small-size products.

How does the one-click automatic adjustment of the servo gluing head work?

When the parameters of the new job are entered into the PLC touchscreen system, the HS-C Series machine automatically calculates the new positions of the servo gluing head in all 4 directions (left-right and front-back). The operator confirms with a single click, and the gluing head repositions electrically to the new coordinates with no manual intervention — in 5–8 seconds vs 3–5 minutes of manual adjustment on conventional systems. The system can also be synchronized with the adjustments of the other stations for a complete one-click format change.

Is the HS-C Series more suitable for ecommerce or for pharmaceuticals and cosmetics?

It works excellently for both, but with different emphases. For ecommerce and fulfillment: the priority is the optional guide for small boxes and the format change without stopping — the plant switches between boxes of 200×150×100 mm and 300×220×120 mm several times a day, and the PLC retains recipes. For pharmaceuticals and cosmetics: the priority is the electric vacuum brush (visually perfect surfaces) and the flap correction system with silicone elastic — because cosmetic/pharma boxes have high aesthetic requirements. UZINEX configures it differently at delivery according to the dominant profile.

What is the difference between the 920C, 924C and 1224C — and why does the 1224C have no listed speed?

The 920C reaches 280 pcs/min on formats up to 730 mm front/back. The 924C reaches 250 pcs/min on the same formats, with a slightly more versatile structure for frequent job changes. The 1224C extends the usable width to 1224 mm — for boxes that are small but wider (for example large blister boxes or flat household packaging). The speed on the 1224C is not listed as standard because it depends strongly on the format/board-thickness combination — UZINEX provides the exact figure after evaluating the customer's concrete product portfolio.

What makes the electric vacuum brush different from conventional cleaning systems?

Conventional edge-cleaning systems use fixed mechanical brushes that do not adapt to format variations and do not capture the removed particles. The electric vacuum brush of the HS-C Series combines the mechanical action of the brush with immediate suction of board and adhesive particles from the flap edges, preventing buildup on the box surface and eliminating the appearance defects typical of processing small boxes at high speeds. On cosmetic and pharma formats — where the box goes straight onto the store shelf — the visual difference is immediate.

Does the HS-C Series also process pre-printed boxes, or only raw blanks?

The HS-C Series predominantly processes pre-die-cut and pre-printed blanks (the typical flow is printer + die-cutter upstream, then the HS-C for folding and gluing). The imported belt transport system, the silicone-elastic pressure paper and the electric vacuum brush are specially designed to protect printed surfaces — exactly for this flow. On raw blanks (without printing) it works identically; the differences appear only in the pressure settings and brush speed to avoid touching sensitive areas.

Is the HS-C Series machine eligible for EU-funded projects?

Yes. UZINEX is a member of the Enterprise Europe Network and supplies equipment for EU-funded projects — NRRP, the Regional Program, the Just Transition Program. The HS-C Series is particularly suitable for applications with a digitalization component (PLC touchscreen, recipe system, format change without stopping) and for plants that produce for ecommerce — a sector in sustained growth and with specific funding measures. UZINEX provides all the technical documentation for public procurement procedures and tenders.
