Molded device housing shell
A molded shell with a screen aperture, speaker details and assembly features — tooling, molding and fit handled as one project.

Perforated moulded panel
Speaker grilles and vented panels with hundreds of holes — core-pin tooling and flow balance in one part.

A perforated panel puts hundreds of small core pins in a single cavity. Each pin needs support, cooling and a venting strategy, and the melt must fill around all of them evenly or the panel warps.
This is a tooling design problem more than a molding one: pin layout, plate support, runner balance and ejection positions are engineered together. We machine the pattern in-house and verify hole geometry and flatness on trial samples.
Typical applications
- Speaker grilles
- Ventilation covers
- Filter housings
- Decorative perforated panels
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.
