Magnetic refrigerator door gasket

magnet door fridge gasketWe have over 300 kinds of profiles for magnetic door gasket. With the performance such as high-temperature and low-temperature resistant, corrosion-resistant, aging-resistant and removal-resistant, they are widely used in electric refrigerator, disinfector, distillatory and cabinet. And they can be used as car sealing gasket and other soft gasket.

The sealing function of the refrigerator door gasket is the key to the refrigerator 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 maxim sealing function. Our accumulated technology and know-how in this special field can add great value to the refrigerator makers.

The gaskets made of soft PVC granule can also have a wide application in the wood industry, architecture and metal industry as elements for sealing doors and windows.

Flexible PVC with magnetic strip inserts provide energy-efficient seals without the use of 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 in designing your magnetic gasket . We can extrude flexible, semi-rigid, rigid and dual durometer profiles in PVC. Fax us a sketch for quick response.
