WHY CUSTOM INSERTS
When Standard Parts Are Not Enough
Standard mold parts cover the 80% case. Custom inserts cover the rest: complex cavity geometry, mirror-polished cosmetic surfaces, multi-material mold sections, and replacement inserts for aging production molds. Every insert we ship is machined, polished and measured in-house — so the part that arrives matches the drawing, exactly.
Reverse Engineering
Send the worn original — we reproduce it with restored geometry and finish.
Mirror Finish
Ra 0.02 mirror polish for optical parts and cosmetic surfaces.
CMM Verified
Every insert measured and documented — no surprises at assembly.
FAQ
Questions Buyers Ask
What inserts can you make?
Cavity inserts, core inserts, slides, lifters and other mold components machined to your drawing — including mirror-polished and textured surfaces.
What tolerances do you hold?
±0.002 mm machining accuracy, verified on Zeiss CMM with a dimensional report included.
What steel options are available?
S136 (corrosion-resistant mirror polish), NAK80 (pre-hardened mirror), SKD61 (high heat), 718H (large inserts) — with mill certificates.
How long does a custom insert take?
Typically 7–15 days depending on geometry and heat treatment. Rush service available for urgent repairs.
Can you match an existing insert?
Yes — we reverse-engineer and reproduce inserts from samples or worn originals, restoring original geometry.
Do you provide documentation?
Yes — CMM dimensional report, material certificate and heat treatment records with every custom insert.
