Seminar Overview

Thermoforming is the second-largest plastics conversion process and the only one with zero catalog coverage anywhere — and it's how medical trays, dunnage, aligners, and a surprising share of device housings are actually made. This seminar teaches forming from the product engineer's seat: the process physics (heating, sag, plug-assist, pressure forming, twin-sheet), material behavior (PETG, HIPS, PP, PC, and the aligner-grade PETG/TPU systems), tooling (molds, plug materials, trim fixtures), and the part-design rules that are completely different from injection molding.

The medical half covers formed trays and dunnage as sterile-barrier components (linking M-05): material selection for EtO/gamma, seal-flange design, and the validation expectations for formed packaging. The precision half covers clear aligners: PETG/TPU sheet behavior, pressure-forming parameters, and the trimming/finishing that decides fit.

Every process module carries its QC layer: sheet-gauge control, sag measurement, wall-thickness distribution prediction, and the process validation expectations for formed medical packaging.

Ideal Learner

  • Engineers specifying thermoformed medical trays, dunnage, and packaging
  • Aligner/ortho product engineers
  • Process engineers launching or troubleshooting forming lines
  • Packaging engineers with formed sterile-barrier components

Learning Objectives

  • Explain the process physics and predict wall-thistribution outcomes
  • Select sheet materials against forming window, clarity, and sterilization
  • Design formed parts: draft, radii, undercuts, webbing avoidance, seal flanges
  • Specify trim fixtures and secondary operations honestly
  • Set up process validation for formed medical packaging

Consulting Sessions

Seminar attendees can sign up for individual consulting sessions with the instructor. Sessions are free for registered attendees, first-come first-served — sign up when registering by calling 248-539-0473 or during the seminar.

Seminar Outline

  • Heat, sag, and the forming window
  • Plug-assist, pressure, vacuum: what each buys
  • Twin-sheet: the structural formed part
  • Wall-thickness distribution: predicting and reading it
  • PETG, HIPS, PP, PC, PEI: forming windows and part consequences
  • Aligner-grade PETG/TPU: the precision end
  • Sterilization compatibility for medical sheet
  • Regrind policy and its quality price
  • Mold types: pressure boxes, temperature control, vent sizing
  • Plug materials and their mark-off behavior
  • Trim fixtures: the hidden half of forming tooling
  • Secondary operations: drilling, heat staking, printing
  • Trays and dunnage as sterile-barrier components (M-05 link)
  • Seal flange design for lidding
  • EtO/gamma tray compatibility
  • Validation expectations for formed packaging
  • Clear aligners: pressure-forming parameters that decide fit
  • Gauge control, sag measurement, and process monitoring
  • Workshop: review a formed tray drawing set
