Automotive moulded components
Functional automotive parts — clips, levers, brackets — molded to repeatable tolerances with documented material traceability.

Automotive components are bought on repeatability: the hundred-thousandth part has to assemble like the first. That puts the emphasis on stable process parameters, documented material batches and geometry that does not drift as the tool wears.
We design for wear with replaceable details where friction and abrasion concentrate, run the tool on our own presses, and keep the running-parameter sheet with the mold so the process is repeatable across shifts and, if needed, across factories.
Typical applications
- Clips, levers and brackets
- Interior functional parts
- Under-bonnet components
- Assembly aids and fasteners
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.

Ask for a DFM review and a price for your part
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.
