Foaming & Core Processing System for Sandwich Panel Production Line
The foaming and core processing system is the technical core of a sandwich panel production line.
It directly affects thermal insulation performance, fire resistance, bonding strength, and overall panel quality.
A stable and well-engineered system ensures uniform core density, strong adhesion between metal sheets and core materials, and continuous high-efficiency production.
In sandwich panel manufacturing, the core material forms the functional center of the panel.
The foaming and core processing system is responsible for:
Precise preparation of core materials
Uniform distribution between upper and lower steel sheets
Controlled curing and bonding processes
Any instability in this system may lead to poor insulation performance, delamination, or inconsistent panel thickness.
The foaming and core processing system can be configured to handle different insulation materials based on project requirements.
Features
High-precision chemical metering
Stable mixing and injection
Uniform foam structure
PU/PIR panels are commonly used in cold storage, industrial buildings, and cleanroom applications.
Features
Continuous rock wool board feeding
Strip cutting and turning systems
Uniform core density control
Rock wool panels provide excellent fire resistance and acoustic insulation.
Features
Continuous EPS feeding and alignment
Accurate EPS cutting and sizing
Consistent core thickness control
EPS sandwich panels offer a lightweight solution with good thermal insulation and economical production costs.
The foaming and core processing system can be configured to handle different insulation materials based on project requirements.
The PU/PIR foaming machine is responsible for accurate dosing, mixing, and continuous injection of chemical components.
