Seminar Overview

Miniaturization is a polymer problem: walls below 0.3 mm, parts under a gram, features at tens of microns — and the entire molding discipline changes. This seminar teaches micro-molding: machine technology (injection units and screw-pump precision at sub-gram shots), mold technology (micro-milling, EDM, insert tooling, venting at micro scale), process science (injection velocity profiles, cavity-pressure control at micro scale), and the metrology that proves a 0.2 mm feature is actually 0.2 mm.

The design half covers the miniaturization DFM rules: wall-thickness limits per material, flow-length ratios at micro scale, micro-feature demolding (draft at 5 microns), gate strategy for micro parts, and the warpage behavior that dominates at small scale. Medical devices and connectors — the estate's two hottest verticals for this content — supply the running examples: micro-fluidic housings, connector housings at 0.35 mm walls, micro-molded valve components.

Playbook line that proves the demand: 'Miniaturization is a polymer problem' — every density roadmap (connectors, appliance controls, tool electronics) thins walls and lands weld lines in critical zones. This is the course that answers it.

Ideal Learner

  • Engineers on connector, medical, and micro-electronics programs
  • Molding process engineers moving to micro scale
  • Mold designers building micro tooling
  • Metrology and quality engineers proving micro features

Learning Objectives

  • Specify micro-molding machine capability honestly (shot size, injection precision)
  • Design micro features: walls, draft, gates, demolding at micron scale
  • Control micro-scale warpage and shrinkage behavior
  • Choose metrology for micro features: what can prove 0.2 mm
  • Diagnose micro-molding defects: short shots, flash at 5-micron parting lines

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.
