Fully Automatic Servo Hot Foil Stamping Machine for Top and Side Decoration of Cap Closures

A fully automatic servo hot foil stamping machine built for two-colour decoration on the top and the side of cap closures — model SAP-S01-TS, two stations, 105 × 70 mm maximum print area, and vision registration for positioning that repeats from the first carton to the last.

Closures arrive from an inclined feeder, index through two stamping stations where the top and side decoration are applied, and leave finished — no second pass, no manual reloading between the two faces. Servo control runs the stamping motion, and the vision system reads each cap before stamping, so the mark lands on the same position regardless of small moulding variations in the shell.

Technical Specifications

Speed figures depend on artwork, foil and cap material — confirm with a sample run on your own closures before planning a line around them.

Description

Servo-driven hot foil stamping platform for cap closures, configured for top-and-side decoration in two colours. The two stations work on the same indexing path, so a cap that needs a logo on the top and a band on the side is finished in one cycle instead of two. Vision registration compensates for shell tolerance; servo motion keeps stroke and dwell repeatable, which is what holds foil registration through a long run.

Key Features & Benefits

Two-Colour, Two-Station Decoration

Both stations run on the same cap path: the top face and the side wall are stamped without unloading the part between operations.

Vision Registration

Each closure is read before stamping, so the impression is positioned relative to the actual cap rather than to a nominal centre — the practical answer to moulding tolerance on printed or lacquered shells.

Servo-Controlled Stamping

Stamping stroke and dwell are servo-driven and set in the controller, giving repeatable pressure cycle to cycle instead of a pneumatic stroke that drifts with air supply.

35–50 pcs/min

Output is stated for the standard configuration; confirm against your cap size, foil and decoration area before planning downstream packing capacity.

105 × 70 mm Print Area

Covers the logo and band sizes used on beverage, spirits, cosmetic and pharmaceutical closures, with 45 mm top-face stamping for full-disc marks.

Automatic Feeding and Discharge

Inclined feeder and automatic discharge keep the machine running without an operator loading caps by hand.

HMI Control with Saved Parameters

Temperature, speed and stamping position are set on screen; saved recipes make switching between cap models a recall step rather than a full re-setup.

Closure-Focused Construction

Frame, fixture and foil path are laid out around cylindrical caps and tubes rather than adapted from a bottle printer.

Applications

• Spirits and beverage closures. Top medallion plus side band on aluminium shells and plastic caps.
• Cosmetic closures. Two-colour branding where the top face carries the logo and the side wall carries the brand colour.
• Pharmaceutical and personal care caps. Durable foil marks on PP and HDPE closures without distorting the wall.
• Tubes. The same platform handles tube decoration where the print area falls inside 105 × 70 mm.

Need printing and stamping in one line instead of two machines? The combined platform is usually the better fit: bottle cap screen printing and hot stamping machine. For closures that lose ink after packing, the cause is usually surface energy — see why ink smears or flakes on PP bottles.

Machine Details & Structure

The photos below are taken on the SAP-S01-TS itself: the feeding end, the registration and treatment head, and the two stamping stations with their foil paths. They are the parts that decide whether a two-colour top-and-side mark repeats, so they are worth looking at before you compare prices.

1. Turntable Cap Sorting and Orientation

Caps are dumped into the turntable and picked up in a single orientation before they enter the stamping path — the turntable, not the operator, sets the cap direction, so the mark lands on the same face at every cycle.

2. Inclined Cap Feeder and Elevator

Caps are lifted from a floor-level hopper into the inclined feeder that delivers them to the indexing table. The elevator module is the tall section on the left; the main stamping unit stands beside it.

3. Side-Wall Registration Camera and Plasma Treatment

Looking into the machine: the side-wall registration camera reads each closure before the stamping station, and the plasma treatment head sits just ahead of it to raise surface energy so the foil bonds on the first pass. If your closures carry a print or a seam that the decoration must align to, this is the station that does the work.

4. Two Stamping Stations and Foil Path

Both stamping stations sit on the same indexing path, each with its own servo head and foil spool, so the top face and the side wall are decorated in one cycle rather than two passes.

Front view: guarded stamping windows, the HMI touchscreen on the right, and the discharge chute at the lower front where finished caps leave the machine.

5. Machine Details at a Glance

PLC with HMI touch control; automatic sorting with counting that separates caps into preset quantities; the stamping result itself; and the automatic unloading and collection system. Counting is what makes box packing efficient — caps are batched as they leave, not tallied by hand afterwards.

FAQ

What can this machine decorate?

Caps, closures and tubes — plastic and aluminium. Two-colour work on the top and the side in one pass, with a 105 × 70 mm maximum print area and 45 mm top-face stamping.

What is the real output?

35–50 pcs/min in the standard configuration. Actual output depends on cap size, decoration area, foil type and how the caps are fed — verify with a sample run on your own closures.

Do I need vision registration?

It matters when the shell carries a print or a seam that the foil must align to, or when moulding tolerance shifts the cap centre. If your caps are plain and the mark is centred by the fixture, ask us whether the vision option is necessary for your job.

Can you customise fixtures for our caps?

Yes — custom jigs for different diameters and heights. Drawing-based, sample-based and full customisation are all available.

Can the voltage be adapted to our market?

The machine is built for 380 V; voltage, frequency and plug are customised to the destination market on request. Confirm your site supply before ordering.

What is the lead time and warranty?

35 days for one set. Core components carry a 1-year warranty, with remote technical support and spare-parts supply; overseas on-site service can be arranged.

Can we test our caps before buying?

Yes. Send samples and we will run a real stamping test and provide video of the result; factory visits for on-site testing are welcome.

Package & Delivery

Machines are packed to standard export specification, vacuumed where necessary and packed into a fumigation-free wooden case, then delivered to seaport or airport by direct line truck.

Export packing: the machine is secured and packed into a fumigation-free wooden case before sea freight.
