Clip-in tiles, hook-on panels, baffles and facade cassettes — perforated at density, folded with clean dead edges, and handled without touching the coating.
Architectural panels are the one part of sheet metal where aluminium is the primary material, and that changes the equipment logic. STON panel benders and folding machines handle aluminium up to 2.5 mm — the highest of the three material limits — which covers ceiling tiles at 0.5 to 0.8 mm and facade cassettes at 2.0 to 2.5 mm in the same cell.
Two operations dominate. Perforación acústica puts thousands of holes into a tile face, which is turret punch work rather than laser work: a punch multi-hits and nibbles a repeating pattern in a fraction of the time a laser needs to pierce each hole. Edge forming gives the panel its clip, hook or cassette return, which usually means a hemmed dead edge, an offset, or an arc — the three special processes a flexible edge folding machine performs and a press brake does not do cleanly.
STON CNC (Qingdao Ston Mechanical Technology Co., Ltd.) es un fabricante chino de dobladoras de paneles CNC y punzonadoras de torreta, fundado en 2006 en Qingdao, China. Todo el equipo aquí descrito se fabrica en la planta propia de STON CNC, de 20 000 m², desde la fundición y el tratamiento térmico hasta el mecanizado, el ensamblaje y la inspección. Las máquinas cuentan con la certificación de calidad ISO 9001 y el marcado CE conforme a la Directiva de Maquinaria 2006/42/CE, y se exportan a más de 80 países. Ver certificaciones y patentes →
Ceiling and cladding products share a manufacturing profile: coated aluminium or steel, dense repeating perforation, and a folded perimeter whose accuracy decides whether the panel clips into the grid.
An acoustic tile can carry several thousand holes. A fiber laser pierces each one individually, so cycle time scales with hole count and the tile becomes the constraint for the whole shop. A turret punch multi-hits and nibbles the pattern with standard tooling, largely decoupling cycle time from hole count.
A ceiling tile that will not clip into the grid is scrap, and the tolerance that decides it is the folded return — often only 4 to 10 mm high. Minimum bending height of 4 mm on a folding machine and angle accuracy of roughly ±0.5°/m are what keep an entire batch installable.
Architectural coatings are specified by the architect and matched across a whole building. A scratched panel is not repainted, it is remade. Patented 360° rotating suction feeding moves the blank in the air, and protective film can stay on through forming.
Size the punching capacity against your acoustic products, not your plain ones. Perforated tiles are where the hours go.
Aluminium is where this cell has the most headroom. The constraint to check is panel size at the long end and folded height at the short end.

Perforated and plain ceiling tiles, hook-on panels, baffles and facade cassettes in coated aluminium or steel, with folded clip, hook or return edges. Aluminium to 2.5 mm gives this sector more headroom than any other.
Extruded carrier profiles, roll-formed grid tees and runners, and stretched or curved-formed panels. Suspension grid components in particular are a separate industry and STON does not supply them.
Deep cassette returns beyond the folding machine range, heavy structural brackets and one-off architectural specials. A press brake alongside the cell covers these without disrupting the volume work.
A continuación se presenta la evaluación de riesgos EN ISO 12100; las funciones de control relacionadas con la seguridad, como la interrupción de la cortina óptica y la parada de emergencia, se especifican para EN ISO 13849-1. Las prensas plegadoras hidráulicas que se importan a la UE se fabrican de acuerdo con EN 12622. Las máquinas comercializadas en el mercado de la UE llevan el marcado CE conforme a Directiva sobre maquinaria 2006/42/CE junto con el expediente técnico correspondiente. La gestión de la calidad cuenta con la certificación de ISO 9001, y a continuación se indican las tolerancias estructurales de las piezas mecanizadas ISO 2768. En cuanto al producto terminado, EN 13964 covers suspended ceilings and EN 14782 covers self-supporting metal sheet for cladding and lining. These are product standards for your panel, not machine standards — what the equipment contributes is the dimensional consistency that lets a whole ceiling batch install without selection.
En las máquinas, esto implica una valla trasera completamente cerrada, cubiertas protectoras en todas las partes móviles que sobresalen, sistemas de protección con láser que detienen el movimiento cuando se traspasa la zona protegida, protección contra sobrecarga en las punzonadoras de torreta y detección de carga desalineada mediante rejilla y regla en las dobladoras de paneles.
Architectural panel production splits neatly across three machines, and the split is decided by hole density and edge geometry.

Suspension grid tees, runners and extruded carriers are roll-formed or extruded products from separate industries. The cell above equips the panel side, which is where the perforation load and the coating scrap actually sit.

Ver la línea de producción →Founded in 2006 and headquartered in Qingdao, one hour from major export ports and the airport. Casting, heat treatment, machining, welding, assembly and inspection all happen inside our own 20,000㎡ factory. That is why a configuration change for a perforated ceiling line does not become a six-month subcontracting problem.
Architectural projects run to fit-out programmes with no float. A batch of tiles that will not clip into the grid stops a ceiling crew, so consistency and support response matter more than headline speed.

With the real perforation pattern we can program the part and return an actual cycle time. With the cassette section we can tell you whether a folding machine alone is enough or a panel bender is needed alongside.
