| Process | Materials & scope | Precision & review | Samples to production |
|---|---|---|---|
| Metal stamping | Steel, stainless steel, aluminum and copper; 0.2–2.0 mm sheet can be reviewed. | ±0.02 mm on critical features, subject to drawing and process review. | Samples / die trials → sample approval → production. |
| Laser cutting & bending | Material, thickness and flat dimensions reviewed from drawings. | Confirmed against bends, hole locations and assembly fit. | Cut / bent samples → agreed production route. |
| Finishing & inspection | Powder coating, spray coating or plating to suit the substrate. | Appearance, coating thickness and inspection methods agreed per project. | Sample approval → batch inspection. |

Project and process examples
From early samples to continued supply
The CPE enclosure shows a phased delivery route. The shielding cover and battery housing explain typical process decisions, not completed customer projects.
Actual project · anonymized
CPE router metal enclosure
- First sample · 3 days
Laser cutting and bending provided the first enclosure for customer review.
- Revised sample · another 3 days
Customer changes were incorporated before sample approval.
- During tooling
The same laser-and-bending route supplied urgent orders while die development ran in parallel.
- Tooling · 3 weeks
The progressive die was completed and production switched to stamping.
- Problem
- The customer could not wait for tooling: they needed samples fast, then placed an urgent 3,000-piece order before the die existed.
- Result
- During the 3-week die-development period, laser cutting and bending delivered three batches of 3,000 pieces each, 9,000 pieces in total. Production then switched to stamping without a supply gap.
These timings describe this project only. A new project’s schedule depends on the drawing, changes, tooling and agreed plan.
Typical process example
PCB shielding cover
- Problem
- A thin PCB shield may need controlled flatness, burr direction and reliable board-contact edges.
Route · Review objective
- Route
- Review punching direction, material, deburring and inspection gauges before finalizing the die.
- Review objective
- Agree contact-edge, burr and fit checks before approving samples.
Typical process example
Battery pack metal housing
- Problem
- A battery housing can involve strength, corrosion protection, grounding and fit between multiple parts.
Route · Review objective
- Route
- Review material, forming, finish, inspection and packaging before sample validation and pilot production.
- Review objective
- Agree the part inspection and assembly checks; system performance remains subject to the buyer’s validation.
Start with a conversation
Have a part in mind? Let’s talk.
Share a sketch, photos or the intended use. We can discuss materials, manufacturing options and assembly risks before preparing a quote.
Can you review a project without complete drawings?
Yes. Send the available 2D or 3D files, sample photos, material, thickness or intended use, and we will first identify missing information and the main manufacturing risks.
What if I have not chosen between stamping and sheet metal fabrication?
We can review both routes. Based on the part structure, quantity, precision, appearance and cost target, we will assess whether stamping, sheet metal fabrication or staged validation is the better fit.
Which risks do you review before tooling?
We focus on material, sheet thickness in the 0.2–2.0 mm review range, critical-feature tolerances down to ±0.02 mm when the drawing and process allow, bending or drawing risk, burr direction, visible surfaces, finishing, inspection method and annual volume.
Can we start with samples or a small production run?
Yes. HARVLAND supports no-MOQ sample validation when the route is feasible. Early-stage projects can confirm fit, appearance and critical dimensions through samples, a pilot run or a simplified validation route before committing to production tooling.
Can you support finishing and inspection documents?
Yes. Depending on the project, we can coordinate powder coating, plating, anodizing, screen printing and marking, and provide sample inspection reports, material documents or project-specific quality records.
