Factory Acceptance Checks for a Six-Head Embroidery Machine
A buyer's guide to defining pass or fail checks for a factory acceptance test on an automatic multi-head embroidery machine, using the catalog reference values as a starting point for RFQ and demonstration questions.
Decide before the factory acceptance test which stitch-out will serve as the pass or fail reference, and require the supplier to run it on all six heads rather than one. A single-head sample can hide head-to-head differences that matter in production.
Build the test around the catalog reference values, treating them as reference only: six embroidery heads, a standard embroidery area per head of 900 × 1,500 mm, and a maximum machine speed of 1,200 rpm. Ask the supplier to state the actual area and speed of the offered model, and to confirm the stitch file and fabric used for the test.
Useful checks include whether each head produces the same design registration and thread tension, whether the full reference area can be embroidered without fabric distortion, and whether the machine runs the test design at the stated maximum speed without stops or faults. Ask for the acceptance criteria in numbers, not descriptions.
Before requesting a quote, confirm with the supplier what test design, fabric, thread, and acceptance tolerances will be used, who witnesses the test, and what documentation records each head's result.
