Inner Hole Stripping Machine for Die-Cut Carton Waste | Manufacturer

For packaging manufacturers and printing companies, Instead of removing each hole manually, the machine uses adjustable stripping positions and multiple needles to process several internal waste areas in one working cycle. This makes it particularly useful for die-cut products with repeated holes, windows, slots, or other internal cut-outs.

Inner Hole Cleaning Machine
The HTQK-720 is specially designed to clean inner holes of paperboard packaging products of various shapes and sizes. This machine significantly reduces manual labor, improves work efficiency, and

How to Specify Your Machine Configuration

Avoid sizing errors by sending your die-cut drawing to our technical team prior to quotation. We review:

Sheet Format & Weight

Verifies table size and pneumatic stroke power for heavy cardboard.

Hole Geometry & Count

Determines pin diameters, quantity, and lock plate mounting positions.

Substrate Coating

Ensures pins penetrate film-laminated or UV-coated boards without dragging.

Sample Testing (Pre-Shipment)

Send 20–30 sheets of your die-cut stock for factory acceptance validation.

FAQ

Q: What is an Inner Hole Stripping Machine?

A: It is a post-die-cutting machine used to remove waste pieces from internal holes, windows, slots, and other enclosed cut-out areas in paper, carton, and cardboard products.

Q: What products can the machine process?

A: Typical applications include die-cut cartons, color boxes, gift packaging, paper cards, hang tags, labels, and other paper-based products with internal waste areas.

Q: Can it remove several holes at the same time?

A: Yes. The stripping arrangement can be configured with multiple needles according to the die-cut layout, allowing several internal waste areas to be processed during one cycle.

Q: What is the minimum hole size the HTQK-720 can strip?

A: Standard pins handle holes down to 3 mm diameter. For smaller or densely spaced holes, we supply customized micro-thimble pin plates.

Q: Does the machine require dedicated tooling for every different job?

A: No. The universal lock plate features adjustable mounting channels. Standard round and square holes can be reconfigured using loose pins without buying new molds.

Q: Can it process film-laminated or heavy corrugated cardboard?

A: Yes. Working pressure is adjustable from 5 to 8 bar to provide sufficient punch force for laminated carton stock and multi-layer micro-flute board.
