BASE COMPONENTS
Anatomy of a Mold Base
Top / Bottom Clamping Plates
Mount the mold to the injection machine platens.
Cavity and Core Plates
Hold the cavity and core inserts — the working heart of the mold.
Support Pillars
Prevent plate deflection under injection pressure.
Ejector Assembly
Ejector plate, return pins and guides for part ejection.
FAQ
Questions Buyers Ask
What is a mold base?
The frame assembly of an injection mold — clamping plates, cavity plate, core plate, support pillars, guide system and ejector assembly — onto which the cavity and core are machined.
Do you make custom mold bases?
Yes — custom sizes, plate thicknesses and configurations machined to your specification, ready for cavity work.
Which steel do you use for plates?
718H and P20 grades are standard, pre-hardened for stability. Alternative grades on request.
How accurate are your bases?
Plate machining holds ±0.01 mm; alignment components are hardened and precision-ground.
Can you deliver a complete mold from a base?
Yes — we machine cavities, cores and inserts onto our own bases for a complete mold build (2–4 weeks).
