A precise map of what we build well — sizes, structures, gating, cavity counts, materials — so overseas buyers know before they send drawings whether their project is a fit.
1-cavity or low-cavity tools for engineering evaluation, low-volume production and specialty parts.
Cold or hot runner tools for parts under ~450 × 320 mm, tuned for stable multi-week production runs.
Bridge tools for design validation before committing to a production tool — usually P20 or aluminum inserts.
Core / cavity inserts, wear parts and spare ejector components made to fit into existing mold bases.
Weld-and-recut repairs, insert changes, cavity additions and gating changes for tools already in the field.
Companion tools for related parts in the same assembly, planned together for fitment and finish consistency.
Cavity count is a design choice, not a marketing number. For most overseas projects we recommend 1–8 cavities — that's where our workshop is most stable and cost-effective. For small precision parts, higher cavity counts are possible after a technical review.
| Cavity range | Where it fits |
|---|---|
| 1 cavity | Prototype tools, larger parts, engineering samples, molds where cycle time matters less than tuning. |
| 1 + 1 (family) | Matching left/right parts, assemblies where two parts must be tooled together for fitment. |
| 2 – 8 cavities | Typical range for stable medium-volume production of small and medium parts. |
| Up to 48 cavities | Available for small precision parts after technical review — feasibility, gating balance and cooling checked before we quote. |
Our recommendation: 1–8 cavities typical; up to 48 cavities for small precision parts after review.
Steels commonly used: P20 / 1.2311 for prototype and mid-life tools, 718H / 2738 for pre-hardened production tools, S136 / 2083 for high-polish and optical cavities, H13 / 1.2344 for high-wear areas. Steel selection is agreed before mold design starts.
