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. Perfuração 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.) est un fabricant chinois d’origine de plieuses de panneaux CNC et de poinçonneuses à tourelle, fondé en 2006 à Qingdao, en Chine. Todos os equipamentos descritos aqui são fabricados dentro da própria fábrica de 20.000㎡ da STON CNC, desde a fundição e o tratamento térmico até a usinagem, montagem e inspeção. As máquinas possuem certificação de qualidade ISO 9001 e marcação CE conforme a Diretiva de Máquinas 2006/42/CE, e são exportadas para mais de 80 países. Ver certificações e 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.
Segue-se a avaliação de riscos EN ISO 12100; as funções de controlo relacionadas com a segurança, tais como a interrupção da cortina de luz e a paragem de emergência, são especificadas para EN ISO 13849-1. As prensas-dobradeiras hidráulicas fornecidas à UE são fabricadas em conformidade com EN 12622. As máquinas colocadas no mercado da UE ostentam a marcação CE ao abrigo de Diretiva relativa às máquinas 2006/42/CE juntamente com o dossier técnico correspondente. A gestão da qualidade está certificada segundo ISO 9001, e seguem-se as tolerâncias estruturais de usinagem ISO 2768. For the finished product, 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.
Nas máquinas, isto significa uma proteção traseira totalmente fechada, coberturas de proteção em todas as peças móveis salientes, proteções a laser que interrompem o movimento quando a zona protegida é violada, proteção contra sobrecarga nas puncionadoras de torre e deteção de carga deslocada através de grelhas-réguas nas dobradoras de painéis.
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.
As figuras abaixo descrevem a direção e o mecanismo da alteração. Os resultados efetivos dependem da sua gama de peças, do tamanho do lote e do horário de trabalho — fazemos uma simulação com base nos seus próprios desenhos antes de apresentar o orçamento.

|---|---|---|
| Acoustic tile cycle | Scales with hole count | Largely independent of hole count |
| Clip return accuracy | Operator and tooling dependent | Program-driven, 4 mm minimum height |
| Dead edge and arc returns | Multiple setups or not possible | Standard process on the folding machine |
| Coating damage | Handling between machines | Suction feeding, film retained |
| Changeover between tile sizes | Tool change and gauge reset | Program recall |
| Aluminium 2.5 mm cassettes | Tonnage dependent | Within the forming window |

Lógica de retorno do investimento que utilizamos com os clientes: (mão-de-obra poupada anualmente + redução do retrabalho e do desperdício + produção comercializável adicional) ÷ custo do equipamento instalado. Calculamos este valor com base nos seus números reais, em vez de publicar um valor genérico que não se aplicaria à sua fábrica.

Ver linha de produção →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.
Dez anos a trabalhar com fabricantes de chapas metálicas na Europa, Sudeste Asiático, Médio Oriente e América do Sul. Em vez de apresentar um orçamento para uma máquina a partir de um catálogo, a Vicky parte dos desenhos das suas peças, do tipo de material, da gama de espessuras e da produção pretendida, trabalhando depois com a equipa de engenharia da STON para definir a configuração — uma dobradeira de painel único, uma puncionadeira de torre ou uma linha totalmente integrada de corte, puncionamento e dobragem com carregamento automatizado.
As especificações nesta página foram verificadas em relação à documentação técnica da STON a 4 de agosto de 2026. Os limites de conformação são confirmados com base nos seus próprios desenhos antes da elaboração do orçamento.

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.
