Fume hoods, lab cabinets and instrument housings — many variants, small batches, cleanable edges, and a repeatability you can put in a technical file.
Medical and laboratory equipment is high-mix, low-volume, high-consequence work. A fume hood range, a lab cabinet programme and an instrument housing family together generate hundreds of part numbers in batches of tens, not thousands. That combination rules out dedicated tooling and rewards two capabilities in particular: tooling-free punching, so a new variant is a program rather than a die order, and program recall with stored compensation, so a part made six months ago is reproduced exactly rather than re-proved.
Two further requirements shape the process. Cleanability means folded, hemmed or dead edges rather than exposed cut edges, and radiused internal corners rather than sharp ones — geometry produced at the forming stage. And documentation means the same part must come out the same way batch after batch, because your quality system, not just your customer, depends on it. Program-driven forming with recorded compensation values is what makes that claim defensible.
STON CNC (Qingdao Ston Mechanical Technology Co., Ltd.), 2006 yılında Çin’in Qingdao kentinde kurulmuş, CNC panel bükme makineleri ve taretli delme presleri üreten Çinli bir orijinal üreticidir. Burada anlatılan tüm ekipmanlar, döküm ve ısıl işlemden işleme, montaj ve kalite kontrol aşamalarına kadar STON CNC’nin kendi 20.000 m²’lik fabrikasında üretilmektedir. Makineler, ISO 9001 kalite sertifikasına ve 2006/42/EC sayılı Makine Direktifi kapsamında CE işaretine sahiptir ve 80'den fazla ülkeye ihraç edilmektedir. Sertifikaları ve patentleri görüntüle →
These products share a profile: coated or stainless sheet between 0.8 and 1.5 mm, folded on all four sides, in dozens of size variants across a single product range.
A laboratory fit-out generates bespoke cabinet widths and hood configurations that may never be ordered again in that exact form. Tooling-driven processes cannot absorb this. Turret punching from a program and bending with automatic tool change turn a new variant into an afternoon of engineering rather than a tooling lead time.
Exposed cut edges collect contamination and fail inspection. Hemmed and dead edges, radiused returns and closed corners have to be formed, and a flexible edge folding machine produces them directly with a minimum folded height of 4 mm. Adding them later, by hand, is where small-batch margin disappears.
Service parts, retrofits and repeat orders arrive years after the original batch. If the part was set up manually, it is re-derived by whoever is available. Program recall with stored angle and compensation values means the tenth production of a part is dimensionally the same as the first — which is what a documented quality system actually requires.
For this sector the driver is variant count rather than volume. Configure for changeover speed first and throughput second.
Medical and laboratory work sits comfortably inside the forming window on thickness. The constraints that bite here are part size at the small end and stainless gauge on hygienic products.

Four-sided panels and enclosures in 0.8–1.5 mm across many variants and small batches, with hemmed cleanable edges and dense service cut-outs. Changeover speed matters more here than cycle time.
Deep-drawn instrument bowls and pressed housings, extruded frame profiles, and small instrument enclosures whose four-sided inner size falls below the minimum forming dimension.
Small brackets, mounting plates, prototype housings and any part below the minimum four-sided forming size. In a high-variant shop the press brake also absorbs urgent service parts without interrupting the main cell.

Bitmiş ürün için, EN 14175-2 sets safety and performance requirements for fume cupboards and ISO 13485 governs quality management for medical devices. Neither is a machine standard — but a documented quality system requires demonstrable production repeatability, and stored bend programs with recorded compensation values are a practical part of that evidence.

In a high-variant shop this is a utilisation question. Most equipment manufacturers start with a laser and add punching when service cut-out patterns start repeating.
| Fiber laser | CNC turret punch | Punch-laser combined | |
|---|---|---|---|
| New variant, no tooling | Immediate | Within tooling library | Good |
| Repeating service cut-outs | Pierces each feature | Fastest | Fastest |
| Louvres, ribs, thread prep | Hayır | Evet | Evet |
| Baffle slotting | Slow at density | Fast | Fast |
| Edge condition | Burr-free | Slight burr, deburr may be needed | Mixed |
| Kullanım alanı | Orta | Orta | approx. 40% less than both |
| Best time to buy | First machine | Once patterns repeat | When one part needs both |
| STON bunu tedarik ediyor mu? | Evet | Evet | Evet |
Cleanable edge geometry is not produced by either cutting process — it comes from folding. If hemmed edges are specified across your range, a flexible edge folding machine belongs in the cell regardless of which blanking route you choose.

PBE serisini görüntüle →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 high-variant equipment cell does not become a six-month subcontracting problem.
Laboratory and hospital projects run to commissioning dates with penalties attached. A machine fault that delays a bespoke cabinet delays a room handover, which is why response time is part of the specification rather than an afterthought.
