INCOE Corp., a global manufacturer of hot runner systems, will display a sample of an IML part using INCOE’s SoftGate valve pin velocity control technology for an innovative production method for IML/IMD (in-mold labeling and in-mold decorating) using an important process optimization. As the part, approximately 3 mm thick is produced, the plastic melt is injected between two films, one of which is also fitted with circuits to create an electrical functional film for use with controls.

INCOE introducing direct gating on an IML part with SoftGate

INCOE Corp., a global manufacturer of hot runner systems, will display a sample of an IML part using INCOE’s SoftGate valve pin velocity control technology for an innovative production method for IML/IMD (in-mold labeling and in-mold decorating) using an important process optimization. As the part, approximately 3 mm thick is produced, the plastic melt is injected between two films, one of which is also fitted with circuits to create an electrical functional film for use with controls.

 The combination of IMD and IML technologies was developed by Leonhard Kurz Stiftung & Co. KG in collaboration with PolyIC GmbH & Co. KG, and developed by Roth Werkzeugbau GmbH, with the design and production of a series-ready mold.

The application, using the valve-gate technology provided by INCOE, permits vertical direct gating onto the film without damaging or shifting the film during the molding process. What was once accomplished by gating via an additional cold sub-runner can now be directly gated on the part using SoftGate, with controlled, relatively slow yet smooth valve-pin opening. SoftGate provides gentle melt flow directly onto the film, coating it completely and bonding well with it without damaging it thermally or mechanically. Gating directly onto the film offers a number of benefits, primarily surface quality but also offers problem-free integration of circuitry, production with nearly no reworking, and no sprue/cold runner waste whatsoever.

The finishing touches for the smooth, ‘one-step’ production were performed by machine manufacturer KraussMaffei. According to initial reports from the automotive industry, the method possesses enough potential to unleash a “little revolution” in the automotive interiors segment, thanks to weight savings, operational reliability, and possibly cost and time savings in component production.
