Glass-filled nylon (PA6/PA66+GF) parts
Structural parts in glass-filled polyamide — high strength, abrasive melt, and a mold built for the wear.

Glass-filled polyamide gives stiffness and thermal performance at low cost, and it wears tooling faster than almost anything else. Cavity and core steel, gate size, runner design and cooling all have to account for the abrasive melt and the higher injection pressures it needs.
We build these tools in hardened steels with replaceable gating details where wear concentrates, apply the mould shrinkage that glass-filled grades actually need, and dry the material properly before molding. The part in the photograph is a ribbed structural component with a moulded grid detail.
Typical applications
- Structural and load-bearing parts
- Automotive under-hood parts
- Power tool and appliance components
- Mechanical housings
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.
