We machine non-functional phone bodies that match your CAD envelope, so accessory brands and retail teams can check fit, finish and weight before tooling is cut. Aluminum or plastic, 5-axis, built to ±0.005 mm.
Most dummy phone problems show up on the buyer's desk, not on the drawing.
A 0.15 mm error at the charging port and the Lightning or USB-C plug binds. Buyers return the whole batch, and the accessory launch slips a week. Port and speaker slots need to be cut with micro-tooling and checked against a gauge, not eyeballed.
Raised bezels that sit 0.2 mm proud break the look in product photos. Too low and the lens ring rubs the table. We hold bezel height and step depth on the same setup so the rear face reads flat to the eye and to calipers.
Thin ABS or PC walls move after machining when the blank was molded with internal stress. A 0.3 mm bow kills the seam line. We rough, stress-relieve, then finish, and keep wall thickness above 1.2 mm where the design allows.
Bead blast too coarse and the body looks like a tool, not a phone. Too fine and fingerprints show under showroom lights. Anodized 6061 at Ra 0.8–1.6 μm reads closest to a production handset for display and trade-show use.
From a STEP file to a finished, non-functional phone body in days.
A dummy handset lives or dies on the outer shell. We clamp the blank once and cut the profile, the rear camera plateau, the side button slots and the port opening on a simultaneous 5-axis center. One setup means the datum never moves between features, so the bezel stays concentric with the body and the buttons sit at the right depth.
For aluminum bodies we start from 6061 or 7075 and hold ±0.005 mm on critical faces. Plastic shells run in ABS, PC, PMMA or POM. Walls below 1.0 mm are possible but they flex during clamping, so we add support ribs or machine them in a soft jaw.
A display dummy is judged at arm's length under store lighting. Anodizing in clear, black or a custom color gives aluminum the right sheen. Bead blasting before anodizing sets the texture. Laser marking handles logos and regulatory text down to 1.5 mm character height.
Weight matters too. Buyers notice a dummy that feels hollow. We can machine a thicker rear wall or add a steel slug in the cavity so the body lands within a few grams of the target handset, while keeping the outer envelope identical.
Pick by how the dummy will be used, not by what looks cheapest on the quote.
| Requirement | Recommended route | Why |
|---|---|---|
| Retail display, needs real weight | 6061-T6 aluminum, anodized | Metal heft, durable edges, holds finish |
| Trade show, many units | ABS or PC, machined or vacuum cast | Lower unit cost, light to ship |
| Transparent back panel | PMMA machined and polished | Optical clarity, can be flame polished |
| Accessory fit testing | Aluminum, tight tolerance | Stable dimensions for repeated plug cycles |
| Photo and video props | Aluminum, bead blasted | Matte surface reads well on camera |
| Early ergonomic study | POM or ABS, as-machined | Fast turnaround, easy to revise |
One shop for the body, the fixture and the finish.
Simultaneous 5-axis centers for contoured shells and bezels that need one-setup accuracy.
Milled bodies and turned inserts, pins and small metal details for the assembly.
First-article dummies in days so the design review does not wait on tooling.
Silicone molds for 20 to 50 near-identical units with a consistent surface.
Anodizing, plating, powder coat, bead blasting, brushing and polishing in house.
Display stands, trays and brackets that hold the dummies on the shelf.

What we own and what we can prove on paper.
Fifteen years of prototype and low-volume work, with three wholly-owned plants.
Including 16 simultaneous 5-axis centers and 16 mill-turn centers.
Held on critical features and confirmed with CMM reports on request.
Send a STEP, IGES or X_T file and get feedback within half a day.
Raw material check, in-process monitoring and final inspection on every lot.
ISO 9001, IATF 16949, ISO 13485 and ISO 27001 certified.
Cases, screen protectors and cables need a body with stable outer dimensions. Requirement: repeatable ±0.05 mm on the port and button openings. We hold ±0.005 mm and check with CMM.
Showroom units take handling and drops. Requirement: durable finish and realistic weight. We anodize 6061 and tune internal weight to match the target handset.
Industrial design teams need a physical body to judge grip and button placement. Requirement: fast revisions. We machine one-off bodies and turn changes in days.
Send a STEP, IGES or X_T file, or a physical sample if the CAD is not released yet. We also accept 2D drawings with key dimensions marked.
Within 12 hours you get a quotation plus a DFM note listing any wall thickness, tool reach or tolerance issues we can see.
Yes, to the extent your CAD model defines the outer envelope. We machine to the model and hold ±0.005 mm on critical features.
Be aware that internal cavities and antenna lines may not be in your file. If you need the dummy to match a real handset, send one for reference measurement or provide a full model.
Aluminum if the dummy will be handled by customers, dropped, or needs realistic weight. Anodized 6061 holds up and reads like a real handset.
Plastic if you need many units at lower cost or the body is a temporary study piece. ABS and PC machine quickly and can be painted or vacuum cast for short runs.
These are cut with micro-tooling, typically 0.5 to 2 mm end mills, on the same 5-axis setup as the outer profile.
Bezel height and step depth are checked against the CAD model. If the design has a very sharp internal corner, we will flag it in the DFM note because a standard cutter leaves a radius.
For aluminum, bead blast then anodize at Ra 0.8–1.6 μm. That gives a matte surface close to a production phone and hides fingerprints in showroom lighting.
Mirror polish at Ra 0.2–0.8 μm is available but shows every touch mark. It suits photo props more than handling displays.
Yes. Uploads are kept secure and confidential, and we can sign your NDA or provide ours before you send files.
We do not share customer drawings, model names or program details.
One piece. There is no minimum order quantity, from a single prototype to a 10,000+ part run.
For quantities above roughly 50 units, vacuum casting or a short injection run may cost less than machining each body. We will say so in the quote if that is the case.
Quotation and DFM feedback come back within 12 hours. Production can start within 24 hours of approval, and parts typically ship in 3–5 days.
Complex multi-part assemblies or heavy finishing may add time. We tell you the expected ship window in the quote instead of after the order.
Upload a STEP or IGES file and our engineers return a price, a DFM note and a ship window. One piece or ten thousand, the same process.
