Case Study
Tooling A Multi Part Blood Separator
The blood separator carried in our original product catalogue, built as a multi part assembly of thin clear moulded sections.
Project Challenge
The Problem On The Table
Thin clear sections warp as they cool, and a separator has to stay both dimensionally stable and optically clear across every cavity of every part in the assembly.
Customer Pain Points
- Warp on thin sections breaking the seal between parts
- Clarity varying between cavities on the sections that matter for inspection
- An assembly tolerance stack that no single supplier had ever reviewed as a whole
Our Solution
What We Did
Mold design was completed for the assembly rather than part by part, with cooling layout and gate positions chosen around the thin sections. All cavities were built and sampled in our own tool room.
Manufacturing Process
- 3D mold design across the assembly
- Five axis and EDM cavity machining
- Cooling layout tuned to thin sections
- Cavity by cavity sampling on assembled parts
Supply Chain
How It Was Coordinated
Every cavity in the assembly sits in one plant, so the fit between parts has a single owner.
Quality Control
Sampling was measured on assembled sets, not on individual parts, before the tooling was released.
Final Result
A separator assembly tooled and sampled as one system, with the full tool set held on one site.
Customer Benefit
Fit and clarity problems have one address, and a correction is a tool room job rather than a negotiation between molders.
