Three Projects That Failed, and What Went Wrong

A coatings plant, a pharmaceutical installation and a laboratory-to-production scale-up, each documented with what actually went wrong. Three lessons that apply to any powder processing project.

The Technical Questions Worth Asking When Requesting a Quotation

Ten questions that change the price of a jet mill, in priority order. Material characterisation, PSD acceptance, air quality, chamber-contact materials, scope of supply, and the five that are almost never asked.

The Tool Price Is Visible and the Tool Cost Is Not

The tooling line on a quotation is the insert, not the number of inserts consumed. Four questions that expose the assumption, and why the cheapest repeat order is often the most expensive.

The Part Is Dimensionally Correct, and That Is Why It Is Wrong

Thermal growth on a multi-metre envelope consumes a real fraction of the tolerance budget without appearing as an error on the drawing. Two failure modes, five questions, and what a supplier can offer.

The Tubing Between the Port and the Process Decides How Fast You Can Measure

A datasheet response time is a property of the element, not of the installation. What the volume between port and process does, and when slower is the correct answer.
