Cost planning
Cost per part
Calculate injection molding cost per part using resin, shot weight, cycle time, cavity count, machine rate, scrap, and tooling amortization.
Read guideMold cost breakdown
A line-by-line injection mold cost breakdown covering design, steel, machining, actions, runner systems, sampling, and qualification.

Part design
Design guide
An injection molding design guide for wall thickness, draft, ribs, bosses, radii, undercuts, gates, tolerances, and quote-ready CAD.
Read guideWall thickness
Choose injection molding wall thickness by resin, flow length, stiffness, finish, and process. Learn why uniform walls reduce sink and warpage.
Read guideDraft angle
A practical injection molding draft angle guide covering pull direction, texture, deep features, ribs, bosses, and DFM checks.
Read guideMolding tolerances
Plan injection molding tolerances using functional dimensions, datums, resin behavior, tool layout, process capability, and ISO 20457:2026.
Read guideUndercuts
Understand injection molding undercuts, side actions, lifters, hand loads, bump-offs, and design alternatives that reduce mold cost.
Read guide03
Tooling decisions
Hot vs. cold runner
Compare hot runner vs cold runner molds by tool cost, material use, cycle, gate options, maintenance, color change, and production volume.
Read guideMold lead time
Plan injection mold lead time from DFM and mold design through steel cutting, assembly, trials, correction, validation, and shipment.
Read guideMulti-cavity molds
Choose injection mold cavity count using demand, cycle time, press size, balance, tool cost, maintenance, utilization, and production risk.
Read guide02
Production quality
Material selection
Compare injection molding materials by temperature, impact, stiffness, chemicals, UV, flame rating, moisture, shrinkage, finish, and cost.
Read guideMolding defects
A practical guide to injection molding defects including sink, warp, short shots, flash, weld lines, burns, splay, voids, and dimensional drift.
