Mold Components for Injection Molding
Complete Component Solutions for Every Mold Build and Repair
Everything Your Mold Needs — From One Source
Building or repairing an injection mold requires dozens of precision components, each manufactured to exact tolerances. Sourcing them from multiple vendors means mismatched quality, delayed deliveries, and POs scattered across suppliers.
Tooling Components is your single source for mold components. We stock 15,000+ SKUs across 10 product sections, from sprue bushings to wear plates. Send us your BOM and we will kit, label, and ship everything together — so your mold builders spend their time building, not sourcing.

BOM Kitting Service
Stop sorting through unlabeled boxes. Send us your Bill of Materials and we will:
- Source every component on your list from our 15,000+ SKU inventory
- Kit the order by BOM line item
- Label each part with your PO number, job number, or BOM reference
- Ship everything together so your team can start building immediately
- Flag any items that need substitution or custom manufacturing
Custom & Special Drawings
Need a component that is not in any catalog? We handle custom manufacturing from your drawings, including:
- Non-standard core pins and ejector pins
- Custom sprue bushings with special radii or tapers
- Specialty wear plates and locating components
- Components from reverse-engineered samples
- Modifications to standard components (cut to length, cross-drilled, etc.)
Our Special Drawings service bridges the gap between catalog parts and full custom manufacturing.
