Handheld device enclosure molding
Enclosures for handheld instruments — ergonomics, internal fits and a surface that survives constant handling.

Handheld instruments add two requirements to a normal enclosure: the shape must be comfortable and secure in the hand, and the internal geometry must locate a display, battery and sensor without rattle. Both are tolerance questions.
We build the tool with controlled wall sections, precise internal locating features and a surface finish that resists handling wear, then mold the parts in-house so the assembly fits are proven on production parts rather than on machined prototypes.
Typical applications
- Measuring instruments
- Thermometers and sensors
- Medical handhelds
- Test and diagnostic equipment
Specification
What this class of tool is built to
Our standard specification for this type of tooling, confirmed line by line on the mold design approval sheet before machining starts.
| Mold construction | Two-plate, three-plate, hot runner, stack or family — specified per part |
| Cavity count | Single or multi-cavity, sized to annual volume, cycle time and press tonnage |
| Mold steels | P20, 718H, NAK80, S136, hardened H13 / SKD61 cores |
| Mold work tolerance | ±0.01 mm |
| Machine accuracy | Down to 0.001 mm (Yasoda, OKUMA, GF, Makino) |
| Runner | Cold runner, hot runner or valve gate |
| Surface finish | SPI A1–D3, bead blast, leather grain or your texture |
| Cooling | Machined circuits; baffles or bubblers where geometry requires |
| Ejection | Pins, sleeves, stripper plate, lifters, unscrewing or collapsible core |
| Verification | Swiss Hexagon CMM and Zeiss Contura; dimensional report at T1 |
| Molding | 30 presses from 20T to 300T, in the same building |
| Documentation | 2D/3D drawings, steel and component certificates, parameter sheet, spare parts |
| Lead time | Typically 15–30 days of machining after design approval |
| Tool ownership | Yours — the tool is designed to be transferable |
Values above are our standard capability for this class of tool, not fixed figures for a specific project. Cavity count, steel grade, runner type and finish are agreed with you on the design approval sheet before any steel is cut.

STEP/IGES/X_T files, the resin, your annual volume and target market are enough to get a mold price, a cycle estimate and the risks we can see — usually in 1–2 business days.
