Long Yunsheng Industrial Co., Limited is a small metal stamping house operating from Rm 232 2/F Secure House, 68 How Ming St, Kwun Tong, Hong Kong - 999077, Hong Kong (HK). We set dies, strike short batches and finish brackets for the integrating teams that build the physical side of computer systems and related services. Every job is quoted from the floor, run on the floor and packed on the floor, so the person who answers your question is the person who has the die in hand.

The rail below is how we think about capacity. Each bin holds a service with its own press, its own tooling and its own finishing routine. The widths differ because the work differs: some jobs are two hours of strikes, some are a full day of setup, and some are a week of kitting boxes that nobody sees until the integration line opens them.
Short press runs from a few hundred to a few thousand strokes, priced against real tooling time rather than a minimum order threshold. We hold the die, run the batch, inspect the first article and pack to your count. See how small-run stamping batches are scheduled.
Formed brackets, retaining clips, card guides and enclosure tabs pressed and bent in one setup where the geometry allows. We match hole patterns to your existing hardware so the part drops into a rack without rework. Read the bracket and clip fabrication notes.
A dedicated day on the floor for mounting, shimming and proving a die before the production window opens. You get a setup record with the ram height, the feed line and the first article readings, so the next batch starts cold without guesswork. Book a jig setup day.
Edge break, tumble, brush and coat routines for parts that will sit inside a cabinet or be handled on an assembly bench. We keep finish notes on the job card so the second order looks like the first and the tenth. Review the deburr and finish passes.
A few pieces struck from a first-off die so your mechanical team can hold the part before a production commitment. Samples ship with the strike record, the material certificate and a plain note on which dimensions are still open. Order a sample strike run.
Brackets, clips, fasteners and shims counted into labelled bags that match a single integration step. Kitting is done on the same floor as the strikes, so a missing part is caught before the carton is sealed rather than on your bench. Understand the hardware kitting packs.
Long Yunsheng Industrial Co., Limited opens its strike schedule window every Monday for teams that need short metal runs proved and delivered inside the same working fortnight. Send a drawing set to the floor planner.
Metal stamping looks simple from the outside: a sheet goes in, a formed part comes out. The work that decides whether a project ships on time happens around that single stroke. The die has to be seated square in the ram, the feed line has to be set to a repeatable datum, the scrap has to clear without dragging, and the finish has to be checked before the parts reach a kitting table. Long Yunsheng Industrial Co., Limited is arranged around those four checks because they are the checks that break first when a floor is rushed.
Our building in Kwun Tong is a compact industrial floor rather than a warehouse-scale plant, and we treat that as an advantage. Dies live on a numbered rack within arm reach of the press. The same hands that set the tool also run the first article, which means a dimension that drifts is noticed in strokes rather than in cartons. For teams designing the physical layer of computer systems, that closeness matters more than raw tonnage. A rack enclosure bracket that is half a millimetre out will fight every screw on the assembly bench, and no amount of volume will fix it after the fact.
We describe our work in three movements. Set is the setup day, where a die is mounted, shimmed and proven against a first article. Strike is the production window, where the batch is run in counted lots and inspected at intervals rather than only at the end. Finish is the pass through deburr, tumble, brush or coat so the part is safe to handle and ready for assembly. Hardware kitting packs sit just after finish, because counting parts into a bag is the last chance to catch a shortfall before a customer discovers it.
Large stamping shops optimise for long campaigns, which is rational for them and awkward for anyone building a small number of specialised systems. A team that needs four hundred brackets does not want to buy ten thousand, and it does not want a quote built on an assumption of ten thousand either. Small-run stamping batches exist on our floor so that the setup cost is quoted honestly, the run is scheduled into a real window, and the parts are finished and packed without being treated as an afterthought. The same die can then be pulled again in six months for a second run, because we keep the tooling and the setup record.
Brackets that hold drives, card guides that keep boards seated, clips that retain a cable run and tabs that close a panel gap. These parts are small, they are ordered in modest quantities, and they are almost always needed on a date that was fixed before the drawing was final. Bracket and clip fabrication on our floor is organised around that reality: a first article you can check quickly, then a batch that repeats it closely.
We keep the forming sequence on the job card so a revised bracket does not quietly lose a bend. When a design changes between the sample strike run and the production order, the change is noted against the die rather than absorbed into the next batch without a record.
A single installation step often needs a bracket, four fasteners, two shims and a clip, all arriving in one bag with a label that matches the step number. Hardware kitting packs are assembled by the same team that finished the parts, which removes the handover where counts usually drift. Each bag is counted, weighed and marked, and the carton carries a simple pack sheet.
For projects that span several locations, kitting also reduces the number of separate shipments a site has to receive. One pack per step is easier to store, easier to audit and much easier to explain to an installer who is standing in front of an open cabinet.
Every job passes the same four points, whether it is six sample pieces or a kitted order for a full installation.
We read the drawing for material, thickness, bend radius and hole clearance before a die is chosen. Anything that cannot be struck cleanly in one setup is raised in writing with a suggested alternative, so the decision is made before tooling time is spent.
The die is mounted, the ram height and feed line are set, and a first article is struck and measured. The readings are recorded on the setup sheet that stays with the die for the life of the job.
The batch runs in counted lots with interval checks, not one inspection at the end. Short lots mean a drift is caught early and corrected on the same die rather than discovered in the carton.
After the finish pass, parts are sorted, counted and either bulk packed or assembled into hardware kitting packs. The pack sheet and the finish note travel with the carton.
Long Yunsheng Industrial Co., Limited works in computer systems design and related services, understood as the physical layer of that field: the brackets, clips, guides and small formed parts that let equipment be mounted, closed and serviced. We are not a general fabricator chasing every job that arrives. The floor is set up for sheet metal that can be struck, formed and finished in a short cycle, and we say so plainly when a job sits outside that band.
That focus shapes who we work with. Engineering teams that build integrated systems often arrive with a drawing that has been through several revisions and a delivery date that has not moved. They need a supplier who will read the drawing properly, strike a sample before committing tooling, and then hold the dimensions on the run. The sample strike run exists for exactly that moment: it turns a drawing into a part the mechanical team can test, and it turns a conversation into a decision.
Because we are a small house, the people who quote are close to the people who press. A question about a bend radius or a finish choice reaches the floor the same day it is asked. That is not a marketing claim so much as a description of how a two-room workshop with a single die rack actually operates. The advantage is speed of correction, and correction speed is what keeps a small project on schedule.
For repeat work, we keep the die and the setup record together. A customer who orders a bracket this quarter and the same bracket next year receives parts from the same tool, set to the same recorded height. Consistency between runs matters more than any single perfect batch, because systems are built and serviced over years.
Deburr and finish passes are the quiet part of that promise. A sharp edge on a bracket is a real hazard on an assembly bench, and a coating that fails early turns a reliable part into a maintenance task. Our finish steps are scheduled into the same window as the strikes rather than sent out and hoped for, and the finish notes are written down so the next order is treated the same way as this one.
When a batch leaves one supplier for finishing and then travels to a second site for kitting, every handover is a place where parts can be miscounted, mixed or quietly dropped. We avoid those handovers by keeping deburr and finish passes, sample strike runs and hardware kitting packs under one roof. A carton that leaves Rm 232 2/F Secure House, 68 How Ming St, Kwun Tong, Hong Kong - 999077, Hong Kong (HK) has already passed every stage that could change its contents.
The practical benefit shows up at the installation bench. An installer opens one labelled bag, finds the bracket, the clip, the fasteners and the shims for that step, and does not need to search a loose parts bin. For a project with dozens of steps, that saving compounds quickly, and it removes the most common cause of a stalled install: a single missing clip.
If your team is designing integrated systems and needs a reliable partner for short metal runs, start with a conversation. Send the drawing set, state the quantity honestly, and we will tell you what the floor can hold and when the parts can be struck, finished and packed. If the job does not suit our floor, we will say so rather than run it badly.
Send drawings, quantities and finish notes today and we will answer with a strike window.
