Cometech QC-677T Manual Hot Press – Desktop Thermo Molding / Sample Preparation Press (20 / 50 / 100 kN)
QC-677T is a compact desktop manual hot press designed to provide stable pressure and temperature for hot press molding of plastic, rubber, and other materials for sample preparation, color-matching plates, and specimen flattening.
- Capacities (desktop): 20 / 50 / 100 kN.
- Heating plates: 150 × 150 mm, with adjustable parallelism via four-column structure.
- Temperature: 50–300°C (400°C model optional) with circulation cooling for upper/lower heating plates.

Overview
The Cometech QC‑677T Manual Hot Press uses two independent heating plates and a split-type hydraulic pump so users can clamp the platens under controlled pressure during molding.
The four-column construction improves rigidity and allows heating plate parallelism adjustment to support better compression flatness and repeatable specimen quality.
An F1C controller provides a simple setup interface and clear display of values such as temperature and time so operators can monitor the molding process and reduce human error.
