Refrigerator Manufacturing

Recent innovations in refrigerator manufacturing have led experts to project a $125 billion value on the worth of the market by 2025. These technological advancements in the manufacturing process are allowing refrigerators to become cheaper to run, more energy-efficient and quicker to manufacture.

The manufacturing process of a refrigerator can be broken down as follows:

Outer Cabinet and Door

This stage involves two or more sheets of metal being folded, connected together and then painted; forming the outer cabinet. Commercial refrigerators often use stainless steel as a material for outer cabinets in order to maintain maximum hygiene.

Inner Cabinet

Inner cabinets are commonly made from plastics, shaped through vacuum forming. Traditionally, similar metals as ones used in the outer cabinet were used for inner cabits, but plastics have always been used for inner liners. Sealants are used at this stage to improve insulation and aesthetics. The inner cabinet is fitted onto the outer cabinet using polyurethane foams that expand, once heated in an oven, to add rigidity to the structure.

Cooling System

The refrigeration unit, comprised of a compressor, evaporator and condenser, is attached to the cabinet. Copper tubing is used to connect components within the cooling system together.

Adhesives and Sealants for Refrigerators

Adhesives offer many advantages over traditional fastening techniques. DOWSIL silicone adhesives and sealant, with decades of proven experience in the chemical industry, provide ideal solutions for refrigerator repair and manufacturing.

DOWSIL adhesives and sealants are beneficial through being:

  • Effective over a wide temperature range; from -65ºC to 232ºC.
  • Dielectric over wide thermal cycling conditions.
  • Able to form strong bonds to a wide variety of surfaces and materials.
  • Environmentally friendly and sustainable.
  • Flame-retardant and of low flammability.

Specifically for manufacturers, DOWSIL’s range of adhesive and sealants for refrigerators can be used for seam sealing of plastic to plastic or plastic to metal, and bonding silicone rubber gasket to cover.

Here we explore our recommended range of adhesives and sealants for refrigerators:

DOWSIL 7091

DOWSIL 7091 is a high-performance adhesive and sealant that cures at room temperature. It cures to a tough, flexible rubber and is ideal for bonding metal to plastic parts within refrigerators. Additionally, it can provide unprimed adhesion to steel, aluminium, ceramic and glass.

DOWSIL AS 7096N

DOWSIL AS 7096N is a translucent sealant that is ideal for providing non-corrosive seals where high movement capability is required, such as refrigerator doors. It is easy to apply and provides excellent unprimed adhesion to many substrates. It is also low-odour.

DOWSIL 732

DOWSIL 732 is a multi-purpose adhesive and sealant that provides good adhesion to many substrates. It cures to a tough, flexible rubber and complies with the MIL-A-46106 and FDA 177.2600 industrial specifications. It is available in white, black, clear and aluminium, giving plenty of choice for different refrigerator models.
