Injection mold with side-action slides
Undercuts solved with cam-driven slides rather than a redesign — for parts with side holes, clips, snap hooks or external features.

Any feature that cannot be released along the opening direction needs a mechanism. The tool shown carries side-action slides: hardened slide blocks, angled pins or cams, and wear surfaces that are machined and fitted in-house at ±0.01 mm so the slides close reproducibly for millions of cycles.
Slides add cost and cycle time, so the DFM review always asks first whether the undercut can be removed by a small part change — a shift of a rib, a change of draft, or a snap detail that can be pulled instead of slid. Where a slide is genuinely required, we design it for serviceability with replaceable wear plates.
Typical applications
- Parts with side holes or clips
- Snap-fit housings
- Handles and brackets
- Automotive and appliance components
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.
