Protective covers are thin-wall, high-tolerance products: a tenth of a millimetre of extra wall shows as a bulge, and a poorly positioned aperture exposes the component it is meant to protect.
We design the wall section, corner radii and aperture positions with the tool, choose the resin for impact and scratch resistance, and check fit on the T1 parts. Protective covers can be molded in a colour range from one cavity, keeping tooling cost down.
Typical applications
- Protective covers
- Device and lock housings
- Camera cases with apertures
- Colour-variant covers
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.
