Clamping force is projected area times cavity pressure, plus a safety factor. Where each number comes from, and what both too little and too much tonnage cost you.
Packing is where a profile that passed inspection arrives bent or scuffed. Bundle design, container length utilisation and the specification that prevents claims.
Acrylic fails in the store and at the machine far more often than in service. Two variables decide it: moisture content and thermal gradient.
Sheet over 3 mm is not a membrane, it is a structure. Oven sag, pressure forming, wall retention across a deep draw and the cooling that sets the cycle.
Cut length error is a stack of small contributions plus one large predictable one. Where the millimetres go and which of them you can actually remove.
Rheology, pressure drop, cavity balance, gate freeze, cooling. What each study answers, how to run it, and why running them out of sequence wastes the data.
Solid rod is the hardest simple profile there is. Why the core, not the surface, sets the cooling length — and where voids and bend actually come from.
Thermoformed parts do not hold the mould they were formed on. Shrinkage, spring-back and the compensation that has to be built into the pattern.
The calibrator is a wear part, not tooling you buy once. Vacuum slot layout, water flow, surface finish and the signs that a sleeve is costing you tolerance.
Corrugated conduit is a vacuum forming process hiding inside an extrusion line. How the mould blocks, the air pressure and the wall distribution interact.
Why a colour approved on a plaque fails on the part: let-down ratio, shear history, regrind and the measurement geometry that decides pass or fail.
Cooling is 45-70% of the cycle. How sheet thickness, mould temperature, air assist and demould temperature set the achievable cycle — and where the shortcuts fail.
