EPDM Sealing Strip Extrusion Line, Microwave Vulcanization Tunnel, Rubber Profile Production Equipment
Microwave Vulcanization Oven for EPDM Sealing Strip
This microwave vulcanization tunnel is the core equipment of continuous EPDM weatherstrip extrusion line, adopting microwave + hot air combined vulcanization technology, widely used for automotive, construction and railway EPDM solid, sponge and tri-extrusion sealing profiles.
Working Principle
Adopting industrial 2450MHz microwave dielectric heating. Microwave penetrates into EPDM profile directly; polar molecules inside rubber vibrate rapidly under alternating electromagnetic field and generate heat from inside out simultaneously. The rubber reaches vulcanization temperature in a short time for cross-linking reaction. The microwave section rapidly heats and pre-vulcanizes the profile, while the following hot air tunnel keeps constant temperature to complete full curing, avoiding uneven curing such as under-cure.
Main Structure
Microwave resonant cavity, magnetron & waveguide assembly, circulator water load, anti-leakage choke system, high temperature conveyor belt, hot air circulating heating unit, PLC control system with multi-zone temperature & power adjustment.
Features
- Fast heating, high continuous production speed
- Uniform curing for complex profiles, low compression set, smooth surface
- Energy saving compared with pure hot air oven
- Suitable for mono-layer, sponge, two-layer & tri-extrusion EPDM weatherstrip
- Interlock safety protection for microwave leakage, over-temperature alarm
