Two-cavity container mold
A compact two-cavity tool for cups and containers, with balanced cooling and a polished cavity finish for a clean visible surface.

Mirror-polished and textured mold plates
Surface finishing as an engineered step: hand polishing to SPI classes and texturing for grip, gloss control and brand look.

Surface finish is specified, not improvised. The plates in the photograph are being taken to a mirror finish — the class of work needed for transparent parts, cosmetic packaging and any product where the customer inspects at arm's length under a lamp.
Polishing is done by hand in-house after the cavity is machined and EDM-finished, working through the grit sequence until the agreed SPI class or texture depth is reached. Glass-filled and abrasive resins wear a polished surface faster, so we select the steel with the finish in mind rather than refining a steel that cannot hold it.
Typical applications
- Transparent and optical parts
- Cosmetic packaging
- Gloss and matt consumer products
- Leather-grain and bead-blast textures
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.
