Bridge Tooling — P20 Steel Molds for 50k–100k Shots

Bridge tooling fills the gap between aluminum rapid molds and hardened production tooling. Pre-hardened P20 or NAK80 steel molds give you steel-mold part quality and multi-cavity options, at lead times and budgets well below Class 101 tooling.

Specifications

Lead time to T1 samples	15–25 working days
Typical tolerance	±0.05 mm on critical dimensions
Cavities	1–4, cold runner (hot runner optional)
Best for	Low-to-mid volume production, consumer electronics housings, repeat wholesale orders

When to Choose Bridge Tooling

• Your design is frozen and you have confirmed demand, but volumes do not yet justify a hardened Class 101 mold
• You need a stable, repeatable supply of 5,000–50,000 parts per year
• You want production-grade surface finishes (SPI / VDI textures) on every part
• You are building a wholesale or subscription supply program and want predictable unit costs

Bridge tooling is the tier most of our long-term wholesale customers start in: tooling cost is typically 40–60% lower than Class 101, while part quality is indistinguishable from production tooling.
