Infrared Pre-Shrinking for PET Film Precision Printing - 18 m/min

APPLICATION CONCEPT | ELECTRONICS & PRINTING

CUSTOM INDUSTRIAL INFRARED HEATING

PUBLIC CASE REFERENCE

Pre-shrink PET before print. Protect circuit registration.

A carbon medium-wave cassette uniformly conditions the PET web before screen printing while temperature, tension and line speed define the process window.

The Process Challenge

Untreated PET film can shrink during later thermal curing and disturb printed-circuit registration. Buying pretreated film can increase manufacturing cost.

The Infrared Approach

A carbon medium-wave cassette uniformly pre-shrinks the PET web before screen printing. Temperature, tension and line speed define the process window.

1

UNWIND

Feed PET film

2

PREHEAT

Application Features

Inline pre-conditioning reduces reliance on purchased film
Uniform web heating supports dimensional control
Carbon medium-wave energy suits thin polymer film
Tension and temperature can be coordinated
Compact cassette integrates before the printer
