Heating-seal tester

The Heating‑seal tester is an instrument designed to evaluate the performance of heat‑sealing equipment. It incorporates a pneumatic drive system, dual heat‑sealing sticks and separate temperature and time control modules. The machine can generate sealing pressures from 0 MPa up to 0.8 MPa and temperatures between 20 °C and 300 °C with a precision of ±1 °C. Its control panel allows time settings from 0.01 s to 99.99 h, providing flexibility for a broad selection of packaging applications.

The upper and lower sealing sticks are made of aluminium with an insulating plate and a silicone pad to protect the cylinder and distribute pressure evenly. Typical heating‑seal testers of this class use a power input of about 1500 W and operate on 220 V AC, 50 Hz mains. The device’s overall dimensions are 700 mm × 400 mm × 540 mm and it weighs roughly 30 kg, making it suitable for bench‑top installation. Standard safety features include a pressure gauge and lockable pneumatic valve.
