Plastic injection molding
Primary service page for custom molded parts, from first quote through production release.
Plastic injection moldingServices
Manufacturing services organized around speed, fit, and follow-through.
Use this hub to pick a path. Core injection programs link to dedicated pages. Materials, tooling, and defect libraries link to their own hubs so detail stays on the right URL.

NetProto sells plastic injection molding with one hardened steel tool per part program. This index links to live service pages and to libraries for materials, tooling, and troubleshooting.
Start in Core injection programs when you know the process. Open Libraries when you need resin, tooling, or defect references. Use Compare pages when an alternative process is still on your shortlist.
Core programs
Injection molding service pages
Each card opens a spoke with full detail. The hub stays a router, not a duplicate of those pages.
Family injection molding
Matched multi-part tooling when assemblies share a mold base and release schedule.
Family injection moldingHigh volume injection molding
Repeat production assumptions, cavitation, and program stability for larger runs.
High volume injection moldingInsert molding
Metal or plastic inserts retained in the mold when the design needs a fixed anchor.
Insert moldingOvermolding
Soft-touch or secondary resin over a rigid substrate when grip or seal matters.
OvermoldingSecondary operations
Post-mold steps that keep parts ready for assembly without a second vendor handoff.
Secondary operationsExport injection molds
Documentation and handoff expectations when tooling ownership stays with the customer.
Export injection moldsOne mold lifetime production
Single hardened steel mold path from first shots through repeat orders and maintenance coordination.

When another process is still on your shortlist
These pages explain tradeoffs. NetProto delivers injection molding with hardened steel tooling, not the alternative process itself.
Compression molding comparison
See where compression molding differs from injection molding on tooling and part geometry.

CNC materialsCommon questions before you pick a service page
Where should I start if I only have a CAD file?
Use Online quote and order or upload through the instant quote CTA. Pick a core program page afterward if you need process-specific context.
Does this hub replace the materials or tooling libraries?
No. Materials, tooling, defects, and finishes stay on their own hubs. This page routes you there without duplicating those indexes.
Are compression molding or urethane casting NetProto services?
NetProto delivers injection molding with hardened steel tooling. The compression and urethane pages explain how those alternatives compare so you can decide before quoting steel.
