Refrigerator Door Gasket
The sealing function of the refrigerator door gasket seal is the key to the refrigerator's energy-saving efficiency and determines the life of the refrigerator air compressor to a great extent. Our R&D team has the capabilities to adjust the gasket properties through formula change and modify the cross-section design through FEA analysis of contact shape deform, press recovery, etc. to ensure maximum sealing function.
We have over 300 kinds of profiles for magnetic door gaskets. Our accumulated technology and know-how in this special field can add great value to refrigerator makers. The gaskets made of soft PVC granules can also have a wide application in the wood, architecture, and metal industries as elements for sealing doors and windows. Flexible PVC with magnetic strip inserts provides energy-efficient seals without door latches. These gaskets are NSF-approved. Standard colors include light gray, black and white. PVC temperature range is -20°F brittle point to +150°F melt point.

We will fabricate complete three-or four-sided magnetic gasket assemblies to the exact dimensions of your door. Corners of assemblies are mitered and heat-sealed with precision splicing fixtures for air-tight fit. Back-up magnets are available for non-magnetic door frames. Mounting hole slots can be punched in screw-on gaskets. Screw-on and glue-on gaskets are typically measured to the outside dimensions of the gasket. Snap-on gaskets are measured to the center line/arrowhead of the gasket.
Our die shop will produce a custom die for your particular needs and our engineers will help you design your magnetic gasket. We can extrude flexible, semi-rigid, rigid and dual durometer profiles in PVC. Fax us a sketch for a quick response.
