Sheet Metal Punching Machine 

Metal Sheet Punching Machine: Dies and Molds

This is where the HPM-63S earns its place as a metal sheet hole punching machine: round, square, rectangular, and louvre dies, plus miniature-fuse, 92×92 ammeter, embossing, ventilation, corner, and lock molds (Siemens, briefcase, Mito) — with custom dies available to order. It covers jobs that would otherwise need a guillotine or a separate corner-forming machine.

Each die splits into replaceable parts — punch, die (matrix), connectors, and locking nut — instead of the old single-cast mold. When one part wears, only that part is replaced, keeping tooling costs well below a single-piece-mold machine.

Common die types include:

• Round dies — holes up to 34 mm for signal lamps, bolts (M4 and up), and cable glands
• Small square dies (7×7, 9×9, 15×15 mm) — widely used in place of screws and fasteners
• Square die (22×22 mm) — a legacy switchgear-panel standard, still produced on request
• Miniature fuse dies — among the most-used tools in panel manufacturing, often sized slightly larger to allow for post-punching paint thickness
• Straight-cutting square die — an economical alternative to a guillotine for parallel cuts
• 92×92 mm ammeter die — one of PAYAPRESS’s highest-demand custom dies
• Embossing (offset) die — raises standoff bumps for mounting clearance or joining two panels
• Lock dies — Siemens-type (most common), briefcase-type (also used in fire cabinets and ATM enclosures), and Mito-type (popular for its refined look)
• Ventilation louvre dies — double-row (aligned via reference marks for long, even rows) and triple-row (lower airflow efficiency but a compact look favored on LV/MV panels)
• Corner-notching dies — simple notch (up to 50 mm standard), double-bend, and fully custom corner dies, offering a lower-cost alternative to a dedicated corner-forming machine
