How We Build Precision Blow Molds
We build precision blow molds that hold ±0.15mm wall thickness and ±0.02mm cavity tolerance. Every mold ships with a full CMM dimensional report and ultrasonic wall thickness mapping from T1 samples at 20+ measurement points. Not on request. Not as an extra line item. Standard.
The difference between a standard blow mold and a precision one comes down to three engineering decisions: Moldflow simulation before cutting steel, conformal cooling that holds temperature uniformity within ±2°C across the cavity surface, and inspection that doesn’t take shortcuts. We’re in Taizhou, Zhejiang. Building extrusion blow molds since 2013.

Frequently Asked Questions
What tolerances can you hold on a precision blow mold?
Cavity: ±0.02mm, CMM verified. Wall thickness: ±0.15mm standard, ±0.3mm on large surfaces, ultrasonic verified. We’ll give you achievable numbers for your specific part during DFM.
How do you verify precision on a blow mold?
Three-stage: in-process checks during machining, full CMM report after assembly, ultrasonic wall thickness mapping on T1 samples at 20+ points. You get all three reports.
What's the difference between standard and precision tooling?
