How to Use
1
Select your product's plane size and depth from the button groups.
2
Choose the undercut complexity that matches your part geometry.
3
Set cavity count, steel grade, runner system and surface finish from the dropdowns.
4
Read the estimated cost range on the right and request a formal DFM quote.

Industry Insight
Undercuts (slides & lifters) and hot runner systems are typically the two biggest cost drivers in injection mold tooling — often adding 35–75% to a base mold price. Locking these decisions early avoids costly engineering change orders.
Inputs — Configure Your Mold
1) Product plane size (L × W)
Plane size affects plate size, machining time, mold base standard, and required injection machine tonnage.
2) Product height / depth
Depth changes core length, cooling layout, ejection stability, and the risk of deflection and warpage.
3) Side-wall undercut
Undercuts add slides/lifters, precision fits, extra steel, and assembly time — often the top cost driver.
Cavities
More cavities raise machining cost but lower cost-per-part at production volumes.
Steel / Mold Life
Steel impacts cost, polishability, corrosion resistance and lifetime cycle count.
Runner System
Hot runners raise mold cost but cut scrap and improve process consistency.
Surface / Cosmetic
Cosmetic and high-gloss finishes add polishing time and stricter tool-mark control.
