In a recent blog post, we discussed benefits to using a foam-in-place adhesive dispensing equipment system.
These benefits included:
- Reduced labor costs
- Reduced material costs
- Reduced in-process inventory
While these systems are used in a range of applications, such as automotive door handles and electronics, they also play an important role in the assembly of appliances.
Foam-in-place adhesive equipment systems enable appliance manufacturers to improve cycle time by replacing tape and reducing manual labor.
This is important for refrigerator and freezer cabinet sealing applications in particular.
For example, when urethane foam is injected into the cabinet of a fridge or freezer during assembly, a chemical reaction occurs, causing the foam to expand. A foam-in-place adhesive is then used to minimize the amount of urethane insulation foam that leaks out from this expansion. As a result, the system ensures the foam is contained within the cabinet of the appliance. This greatly decreased clean up time and improved productivity.
For dishwashers, foam-in-place adhesive systems are used in gasketing. Gasketing ensures water leakage doesn’t occur when a dishwasher is running. This system can also be used for sound damping purposes.
Smart Appliance Adhesives for Foam-in-Place Systems
Bostik manufactures quality adhesives designed specifically for foam-in-place systems. In particular, these include:
- Thermogrip H5211-02: This hot melt adhesive is an elastic material with excellent foamability and minimal tack, allowing for ease of clean up. As a result, it is an ideal option for appliance cabinet sealing.
- Thermogrip H4318: Designed for refrigerator and freezer cabinet sealing applications, this hot melt pressure sensitive adhesive is formulated using a soft, elastic material allowing for ease of clean up and simple application.
- Thermogrip H5068A: This foam-in-place cabinet sealing adhesive is specially used for french door fridges. The higher internal strength of this material resists more force placed on the product from the expansion of the foamed urethane (because the foamed urethane is expanding in a smaller volume/space compared to the whole fridge cabinet).
