Thermoforming is the process that gets acrylic out of flatland — heat the sheet, shape it over a tool, cool it, trim it. The process walk, what forming does to the material, why the mold is the real product, and why trim is half the job.
Somewhere past a certain size, a vitrine stops being a bigger version of a small one and becomes a different engineering problem — panels bow, sheet sizes run out, and the cover becomes a two-person lift. The design constraints to adjust for before quoting, not after.
The lab order book is wider than people expect — enclosures, shields, tanks, jigs, demonstration models, and the one-off replacement part for an instrument nobody makes anymore. The map of what labs actually order, with the responsibility split and the procurement realities built in.
Countertop real estate is negotiated in inches, so the spec starts with the footprint and designs inward — not with the product and outward. The five numbers every countertop quote needs, the load-thickness conversation, and the omissions that surface at prototype.
The most common field disappointment in display work is a shelf that sagged — slowly, months after delivery, exactly as the physics said it would. How span, load, and time actually pick a thickness, and why one step up in thickness beats almost every other fix.
The workhorse lab order is a box around an instrument — but a dust cover, a draft shield, and a guard over a moving stage are three different designs. What each job changes, the measurements to take first, and the access features to ask for by name.
The guarding decision belongs to the plant; executing it precisely belongs to the fabricator. A design guide for the transparent guard itself — material trade-offs, span-driven thickness, the mounting details that make a guard serviceable, and sightlines you can actually specify.
An agency promises a client something physical, then has to deliver it through a fabricator. This guide is about managing that middle — pitch-stage feasibility, the handoff, production, and the client promise riding on all of it.
Instead of writing “polished, flawless finish,” write the grade — Production, Display, or Museum Archival, each defined by the Inspection Distance at which cosmetic characteristics may become visible. The drawing-note syntax, per surface, with the cost logic.
The seven most common ways an agency brief loses schedule at the fabricator, why each one happens, and the one-line fix — assembled into a producer’s brief template you can reuse.
