Custom acrylic and plastic fabrication for labs and research engineers: enclosures, tanks, beta shields, replacement guards and sashes, jigs, material choice, tolerances, and university purchasing.
Engineers trained on machined metal put ±0.005 everywhere by reflex — and on an acrylic lab fixture that habit buys slower quotes, not better parts. The published per-process ranges, what genuinely needs a tight callout, and the one drawing note that fixes most of it.
Labs inherit their material choices from whoever built the last fixture. The four axes that should actually decide — clarity, impact, buildability, chemistry — mapped to the fixtures where each material wins, and the one question that shortcuts the whole decision.
A custom part often waits longer in purchasing than it ever will on the shop floor. How to move a fabrication order through university procurement: the quote that survives review, what makes a sole-source justification writable, when the job actually enters the schedule, and the fiscal-year-end timing that catches labs every year.
Grant periods end on dates the sponsor set. Beam time is booked. The site visit is on the calendar. A research buyer needs date language, not lead-time estimates — and the Production Scheduling tiers are exactly that language. Which tier fits which deadline, one worked timeline, and the one-line translation for your purchasing office.
You design in CAD daily — but a part sent to a fabrication shop follows different rules than one milled in the department machine shop. The mindset shift to cut-sheet design, the classic first-drawing mistakes, and the two annotations that eliminate an email round-trip.
Glove-box-style enclosures built to the customer’s design: bonded chamber bodies, machined port rings, transfer-door openings, and pass-throughs located to the drawing. What the fabricator actually delivers — flatness, hole position, joint quality — and what stays the customer’s engineering.
The cracked guard on a fifteen-year-old machine whose manufacturer is gone is the fabrication request facilities teams rarely plan for. Replicate-from-sample: how a broken guard, sash, or shield becomes a drop-in replacement — and a drawing on file for the next one.
Research users order transparent tanks because the walls ARE the instrument — observation, flow visualization, calibration. The joint engineering behind liquid service, the features that make a tank usable, and the honest split: we build to the spec, the lab verifies performance.
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.
Your lab’s safety officer specifies the material and thickness; the fabricator’s job is executing that spec precisely and building a shield people actually want to work behind. The common formats, the geometry worth specifying, and the responsibility split stated plainly.
