Mold Price & Injection Molding Cost — A Practical Guide for First-Time and Seasoned Buyers

Understanding where every dollar goes in a molded-part quotation is the fastest way to cut waste, negotiate intelligently, and launch on schedule. Below you’ll find clear, engineer-friendly answers to the questions buyers ask most often, along with simple formulae you can use before requesting a quote from TaiwanMoldMaker.com.

1 | How Much Does Injection Molding Cost per kg?

Resin Class Typical Raw-Material Cost* All-In Molding Cost / kg (Asia) All-In Molding Cost / kg (USA / EU)
Commodity (PP, PE, PS) US $1.3 – 1.8 US $2 – 3 US $3 – 5
Engineering (ABS, PC, POM) US $2.2 – 3.5 US $3.5 – 6 US $5 – 8
High-Performance (PA GF, PEEK, PPS) US $6 – 35 US $8 – 45 US $12 – 60

*Spot prices Q3 2025, delivered in Taiwan.
All-in cost includes resin, color masterbatch, overhead, labor/robot time, energy and 10 % scrap.

Quick estimate:
All-in cost /kg ≈ (Resin price × 1.15) + (Press rate × cycle time × shots /kg)
where press rate ≈ US $8 – 20 /h in Taiwan, depending on tonnage and automation.

2 | Why Is Injection Molding “So Expensive”?

  1. Tooling Amortization — Steel molds must survive 100 k – 1 M cycles; H13/S136 steel, EDM time and hot-runner systems dominate up-front cash.

  2. Capital Equipment — A 350 t servo-electric press costs US $180 k – 300 k; depreciation and preventive maintenance go into every shot.

  3. Process Control — Scientific-molding sensors, MES dashboards and quality staff add overhead but protect CpK and warranty PPM.

  4. Skilled Labor & Energy — Even with all-electric presses, Taiwan rates ~0.45 kWh/kg molded.

Take-away: Once tooling is paid off, per-part cost drops sharply; that’s why high volume is king in molding economics.

3 | What Is the Cost of 2K (Two-Shot) Injection Molding?

Cost Driver Single-Shot Tool 2K / Two-Shot Tool
Mold Base & Steel 1× 1.4 – 1.8× (rotary / index plate)
Hot Runner 1 manifold 2 manifolds or valve gates
Press Rate Standard press +15 – 25 % (dual-barrel or rotary)
Cycle Time Baseline +10 – 20 % (second shot)

Rule of thumb:
Expect a 40 – 70 % tooling premium and a 15 % part-price premium versus single-material molding, usually recovered within 30–80 k parts thanks to the elimination of secondary assembly, paint or adhesive.

4 | How to Calculate Mold Cost?

Mold Cost = Base Price + Cavities + Hot Runner + Actions + Finish + Validation

Component Quick % of Total
Mold Base (DME / HASCO) 15 – 25 %
Cavity & Core Blocks 25 – 40 %
Hot Runner / Valve System 10 – 25 %
Slides, Lifters, Core-Pulls 5 – 15 %
Texture / Polish 3 – 7 %
Design, Program Mgmt, FAT/PPAP 10 – 15 %

Shortcut:
Estimated Tool Cost ≈ (Projected Part Area cm² × 0.45 kN/cm² × 1.3) + Hot-Runner Premium
Works well for tools ≤ 650 t.

5 | What Does a Mold “Cost” in Real Numbers?

Mold Type Shots Life Lead Time Price Range (Taiwan)
Aluminum Bridge (7075) 5 k – 25 k 2 – 3 weeks US $4 k – 10 k
P20 Family Mold 100 k – 300 k 4 – 5 weeks US $12 k – 30 k
H13/S136 Hot-Runner 500 k – 1 M+ 6 – 8 weeks US $25 k – 120 k
2K / Rotary H13 300 k – 800 k 7 – 9 weeks US $35 k – 180 k

6 | What Is a “Mold Fee”?

A mold fee (also called tooling charge or NRE—non-recurring engineering cost) is the one-time payment that covers:

  1. 3-D mold design, flow/warp simulation

  2. Steel, machining, EDM, texture, and assembly

  3. First-article validation (IQ/OQ/PQ or PPAP)

  4. Ownership transfer paperwork and maintenance kit

Most suppliers invoice 50 % at PO, 40 % at T-0 sample approval, 10 % at PPAP sign-off.

7 | Why Are Molds So Expensive?

  • Material: Premium tool steel (H13, S136, Maraging) costs 5–7× commodity steel.

  • Precision: EDM tolerances often hit ±2 µm; such machines cost > US $200 k.

  • Complexity: Multi-slide, unscrewing, two-shot tools may have 500+ components.

  • Longevity: Automotive and medical programs demand > 1 M cycles without dimensional drift.

  • Opportunity Cost: A tool shop’s spindle and bench hours are finite; pricing reflects capacity allocation risk.
