Refrigerator and Freezer PU Insulation Foaming Solution
Coordinate cabinet and door insulation foaming for refrigerator and freezer production.
Build the Process Around Your Product
Coordinate cabinet and door insulation foaming for refrigerator and freezer production.
Product and material first
Start with the finished-product drawing, material system and acceptance requirements. The process route and equipment configuration are assessed together.
Capacity across the whole process
Define output with preparation, forming/reaction, curing, handling and inspection included. The slowest stage and product changes determine practical line capacity.
Haifeng provides configured metering, mixing and foam injection. Fixture stations, conveyors, handling and material-specific plant services are itemized. Appliance assembly beyond the foaming interface is separately scoped.
From Preparation to Qualified Product
A planning sequence for the specified route. Final settings and acceptance conditions are established through material and part review.
Define cabinet and door families
Review cavity volume, liner/skin materials, injection access and required insulation performance.
Prepare assemblies and fixtures
Position inserts and seal interfaces; confirm fixture support and preconditioning.
Condition and meter foam components
Select the material system and configure conditioning, ratio and shot control.
Information Needed to Configure the Line
Provide these inputs so the equipment range, interfaces and validation plan can be defined.
| Design input | Information required |
|---|---|
| Appliance drawings | Cabinet/door dimensions, cavity volume, liners and injection points |
| Foam system | Blowing-agent system, ratio, density and supplier handling data |
| Output target | Product mix, cabinets/doors per shift and changeovers |
| Factory plan | Fixtures, handling, utilities, ventilation and inspection |
Core Equipment and Integrated Interfaces
Haifeng provides configured metering, mixing and foam injection. Fixture stations, conveyors, handling and material-specific plant services are itemized. Appliance assembly beyond the foaming interface is separately scoped.
High-Pressure PU Foaming Machine | Refrigerators
High-pressure PU foaming machine designed for refrigerator insulation, ensuring high closed-cell content and low thermal conductivity for superior energy efficiency and dimensional stability.
Low-Pressure PU Foaming Machine | Refrigerator Rigid Foam
ow-pressure PU foaming machine designed for refrigerator rigid foam insulation, ensuring low thermal conductivity and high closed-cell content. Ideal for home appliance thermal insulation component production.
Coordinate the Equipment With the Process
Evaluate repeatability, handling and acceptance across the full workflow.
Material-specific configuration
Component circuits, thermal control, mixing and receiving equipment are matched to the approved chemistry and processing window.
Defined interfaces
Haifeng provides configured metering, mixing and foam injection. Fixture stations, conveyors, handling and material-specific plant services are itemized. Appliance assembly beyond the foaming interface is separately scoped.
Documented acceptance
The proposal defines trials, process records, inspection responsibilities and product-specific acceptance conditions.
Related Project Records and Industry References
Review the evidence type on each record. Haifeng project figures describe their own configuration; public industry references identify third-party sources and are not Haifeng deliveries.
