Overview
Depending on part size, resin, and volume, we coordinate tooling, trials, quality documentation, and logistics under a single workflow—so you get reliable parts and predictable schedules.
Routing and tooling are selected to best fit tonnage, resin, geometry, and schedule requirements.
Quick Specs
| Engagement | Best For | Speed | Notes |
|---|---|---|---|
| Prototype (Aluminum) | Early builds, fast iterations | Fast | Lower tool cost; limited life; ideal for DFM prove-out |
| Bridge (Alum/Steel) | Pilot & market validation | Medium | Optional multi-cavity; balances cost & life |
| Production (Steel) | Stable demand, long tool life | Medium | Hardened tool steels; tighter process control |
| Insert / Overmold | Metal inserts, soft-touch grips | Varies | Mold around inserts or add TPE over rigid core |
Our Capabilities
- Low- to mid-volume molding (single- & multi-cavity)
- Insert molding & overmolding (metal inserts, TPE over rigid)
- Gate, runner, cooling, and ejection strategy optimization
- Colorants, additives, and resin selection support
- Secondary ops: de-gate/trim, CNC, ultrasonic welding, assembly
- PPAP/FAI documentation, traceability, and custom packaging on request
Design for Manufacturability (DFM)
- Target uniform wall thickness; use ribs (≈ 40–60% wall) to reduce sink/warp.
- Apply draft on vertical faces (≈ 1–2°; more for textures) to improve release.
- Use generous internal radii/fillets; avoid sharp internal corners to aid flow.
- Size bosses for thread engagement; rib and tie into walls to spread load.
- Call out only CTQs; allow standard tolerances elsewhere to control cost.
- Pick resin for shrinkage, stability, and environment (heat/chemicals/UV).
- Provide STEP/IGES + 2D PDF with cosmetic faces, texture, color, and any knit-line sensitivities.
We’ll review CTQs, resin options, and gating/cooling to confirm achievable specs before tooling release.
Why Partner with Pearson?

Injection Molding FAQs
What tolerances can I expect?
As a baseline, ±0.10 mm is typical for non-critical features. Tighter bands are achievable with the right resin choice, gating/cooling, and GD&T; we’ll review CTQs during DFM.
How fast can I get parts?
Prototype tooling commonly completes in ~2–3 weeks with parts after T1 approval. Production tools typically take ~4–5 weeks depending on complexity. Request a molding quote — include CAD, target volume, resin preference, and any cosmetic specs.
What’s the difference between insert molding and overmolding?
Insert molding encapsulates a placed insert (often metal). Overmolding adds a secondary resin — e.g., soft TPE grip over a rigid substrate — to combine properties.
Can you help with cosmetic quality and assembly?
Yes. We advise on texture/draft, gate vestige locations, knit-line sensitivity, and provide trimming, machining, ultrasonic welding, kitting, and packaging on request.
