Machined mold plates and mold bases
Mold base plates, cavity blocks and inserts machined, ground and fitted in-house — the hidden half of mold quality.

Most mold failures are not in the cavity profile; they are in parallelism, flatness and the fit between plates. A cavity block that sits on an unparallel backing plate closes unevenly, flashes and wears out the shut-offs. That is why we machine, grind and measure plates ourselves instead of buying them in as a finished assembly. The photograph shows one of these plate components after machining.
Plates are prepared on our milling and surface grinding machines, hardened where the application demands it, and checked for flatness and thickness before assembly. Standard components, guide pillars, springs and water fittings are specified from recognised suppliers so your molder can replace them anywhere.
Typical applications
- Cavity and core backing plates
- Sliders and wear plates
- Ejector and stripper plates
- Hardened inserts and blocks
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.
