In the high-pressure world of Original Equipment Manufacturing (OEM), nothing gets a free pass. Every part has to work right out of the box, drop into place without a fight, and keep performing for years. Think about the metal box around a busy airport kiosk or the heavy cabinet that holds power gear in a substation. That metal isn’t just a shell. It holds everything together, pulls heat away from electronics, and stands between expensive boards and rain, dust, or curious fingers.
OEM buyers spend their days hunting down odd-shaped metal pieces that have to match drawings exactly. One hole off by half a millimeter can stop a whole production line cold. A weak weld can kill a product’s reputation overnight. Precision sheet-metal work takes ordinary coils of stainless steel, cold-rolled steel, or aluminum and turns them into finished doors, frames, brackets, and housings through cutting, bending, welding, and painting.
Companies building displays, medical gear, classroom tech, power equipment, or new-energy products can’t gamble on suppliers. Since 2010, San Jun Hardware has done nothing but sheet-metal parts for these exact markets. We’re here to make sure even the smallest bracket fits your drawing the first time, every time.
Good equipment helps, but real accuracy comes from people who watch every step like hawks.
It all starts with a flat sheet. We shear when we can, run plasma on thicker material, and switch to 3000W fiber lasers when the job demands tight corners and clean edges. Our XP1250X and AMADA EM2510 punch presses knock out hundreds of holes fast and dead-on. On material between 0.5 mm and 2.0 mm thick, we hold ±0.1 mm all day long. That matters when a kiosk door has to shut flush on the first try in front of impatient customers.
Once the blank is cut, we give it shape. Three AMADA CNC press brakes bend parts to the correct angle without cracking the metal or leaving bend marks. Operators check grain direction and bend radius every time. Punching and stamping add louvers, embosses, and mounting holes exactly where the drawing says they belong.
Welding turns a pile of pieces into one solid box. We run MIG on mild steel for speed, TIG on stainless when the seam will show, and spot welds when strength and quick cycles matter most. A typical outdoor power cabinet can have 40–50 meters of weld bead; every inch has to be strong enough for ten years in the weather.
Assembly is where everything finally lines up. American Hager automatic riveting presses set rivets in one clean hit. Studs and PEM fasteners go in straight and tight. Our own fitters square the box, check door gaps with feeler gauges, and test locks before the part ever sees a truck.
A perfect part can still rust or scratch in weeks if the finish is wrong. Powder coating gives a tough, even color—pick any RAL or Pantone you want—and shrugs off keys and shopping carts. Aluminum gets anodized, so salt air doesn’t eat it alive. Stainless steel often gets a brushed finish for that clean look hospitals like. When hinges, handles, and the main body all match, the whole machine looks sharp and stays that way.
We take everyday shop skills and turn them into boxes that solve real customer problems.
Self-service machines sit in busy lobbies and food courts. They get kicked, leaned on, and cleaned with harsh chemicals. San Jun Hardware builds floor-standing and wall-mounted payment terminals that take the punishment.
Our Hospital Self-Service Kiosk Enclosures are a good example. These units pack a 17- to 32-inch screen, a receipt printer, and a card reader into one tight package made from cold-rolled steel with extra anti-rust primer. Doctors and patients use them hundreds of times a day without the paint chipping or the door sagging. The same tough thinking goes into 24-, 27-, and 32-inch ordering kiosks in restaurants—solid feel, no rattles, quick transactions.
Outdoor boxes fight sun, rain, snow, and the occasional baseball bat. Our IP65 Outdoor Custom Digital Signage Enclosures and IP65 Self-Service Terminal enclosures keep water out and electronics cool. A 55- or 65-inch outdoor display uses an aluminum-alloy frame, 3500 cd/m² screens you can read in bright sunlight, and carries CE and RoHS paperwork. We also make power-supply enclosures where getting the heat out is just as important as keeping the rain out.
Classrooms need podiums that lift and tilt smoothly all day. Our 23.8-inch Liftable Smart School Classroom Podium Enclosures use heavy steel bases and quiet columns so teachers can adjust height without distracting the room.
For vending, we build the steel bodies for Intelligent Self-service Cabinets and Custom Automatic Distributor Vending Machines. Thick doors, good locks, proper airflow, and full EMC, LVD, and RoHS paperwork come standard.
Smart buyers want a shop that makes their life easier, not harder.
Most jobs start with nothing but your drawing. We figure out how to make it without expensive dies. Odd-angle brackets, slotted connector plates—bring it on. Fifty full-time sheet-metal engineers work only on customer parts, so samples from approved drawings ship in 3–7 working days.
The plant runs under GB/T19001-2008 (ISO 9001:2008). Every year, we put 10% of profit back into machines and training. The result is parts tough enough for military use at normal commercial prices.
Day-to-day numbers that matter:
Quotes usually leave the office within 24 hours.
First samples ship 3–7 days after we sign off on drawings.
If a problem shows up, we track it down and fix it within 48 hours.
With AMADA benders, 3000W lasers, and two-shift production, customers shave weeks off schedules and often pay less per part.
Precision metal work is part skill, part equipment, and part trust. When you need hospital kiosks that stay clean, outdoor signs that survive storms, or classroom podiums kids can’t break, San Jun Hardware has the machines, the people, and the track record to deliver. From the first phone call to the last welded corner, we’re focused on getting your product out the door faster, better, and cheaper.
