Processing Guide

Stabilize material condition, filling and packing before diagnosing shrinkage, warpage or surface defects. Record weight, dimensions and appearance in each trial to establish a repeatable molding window, starting from the selected grade’s processing guide.

Before Molding Trial

Define what the trial must prove before adjusting settings. A clear baseline prevents material, mold, machine, and measurement issues from being confused.

  • Verify the exact grade, lot, color, modification direction, packaging condition, and current TDS before loading material into the molding system.
  • Review drawings for wall transitions, ribs, bosses, weld-line locations, cosmetic zones, assembly loads, and dimensions requiring process capability.
  • Check gate and runner layout, venting, cooling circuits, cavity balance, ejection, mold surface condition, and recent maintenance or modification history.
  • Confirm machine suitability, shot utilization, screw condition, temperature-control stability, available monitoring, and approved startup, purge, and shutdown procedures.
  • Agree on trial stages, sample identification, conditioning time, measurement method, acceptance criteria, and which process variables may be changed.
