Automatic Card Punching Machine Accuracy Depends on Feed and Marks

A card that is punched a fraction of a millimeter off center shows the error at once, on the printed border, the chip position or the edge of the corner. That is why buyers of card production equipment look at what moves the sheet and how the machine finds its place before they look at speed. Hengtong Card Making Equipment Co., Ltd., based in Yongjia County, Wenzhou, builds an Automatic Card Punching Machine that feeds laminated sheets by servo motor and reads position marks with a sensor, and its specification pages list the parts behind that design.

Why Position Matters After Lamination

Lamination bonds the layers into a sheet, and punching cuts that sheet into individual ISO cards. Sheets can distort slightly after heat and pressure, and tooling wears over many runs. An Automatic Card Punching Machine has to find each card's position on every pass, because the cutting step has no way to repair a misplaced cut. The HT-306-4-A3 addresses this with software that sets a different step distance for each card layout, and the maker states that punching precision holds even when the material is distorted or the machine shows mechanical wear.

Feed and Position Marks

The HT-306-4-A3 uses an imported PLC with an industrial touchscreen. Its material Servo Feed System combines an imported servo motor with a precision ball screw and plane guide from Japan, which together keep the sheet moving smoothly over an accurate distance. A sensitive sensor reads the position marks printed on the sheet, so the machine locates each row of cards by the sheet itself instead of relying only on a counted step. The specification of this Automatic Card Punching Machine lists automatic feeding by light-eye reading, and that is what separates it from machines that need an operator to place every strip by hand.

Hydraulic Punching and Moulds

A hydraulic cylinder drives the punching mould, and the maker lists a hydraulic pump from Taiwan with low noise and large flow, hydraulic valves from Taiwan and American seals for long service life. Hydraulic Punching of this kind runs smoothly and quietly, which matters in a plant with several machines running side by side. The punch mould is made from imported Japanese mould steel, a choice that reflects how much load the tooling carries over a production run. The high-speed Automatic Card Punching Machine uses three punch heads and a 3 × 8 layout, which cuts 24 cards from one 300 × 480 mm sheet, and it reaches 10,000 to 12,000 cards per hour.

Two Formats Compared

Hengtong lists a second model for smaller sheets. The PLC touchscreen version works on A4 sheets, 297 × 210 mm and up to 297 × 420 mm, with 10-up or 20-up layouts and five punch heads. Its stated output is up to 7,200 cards per hour.

Matching Output to the Plant

A buyer of an Automatic Card Punching Machine who runs large A3 sheets and wants volume looks at the high-speed model, and a buyer with A4 sheets and a smaller plant looks at the A4 format. Packed weight and crate count matter as much as output, since they set freight and handling at the destination. The high-speed model ships in two crates at about 1,200 kg, and the A4 model ships in one crate at about 380 kg. Hengtong offers selection guidance based on the customer's card product, recipe and planned production capacity, so a buyer of an Automatic Card Punching Machine can choose between formats before ordering.

Supply Behind the Machine

Hengtong also builds the laminators that feed a puncher, and it supplies card making consumables such as PVC adhesive film and laminating pads. A customer can therefore set up lamination and punching with matched equipment from one supplier. The company works on its own patented technology, applies strict control to raw materials and production for batch consistency and traceability, and offers a response team around the clock for export customers. An importer who lists an Automatic Card Punching Machine from Hengtong beside its laminators can quote a full line and keep after-sales contact in one place.
