FAST FACT

  • → Gluing needs to be a well thought out and well tested solution. Gluing needs to be well controlled with
    proper dosing equipment, refrigerated storage, thorough application and curing instructions respected and complied to. Environmental and fatigue testing of samples is essential to ensure the correct functioning of the product over time. We do frequently use glue in our assembly products
    however, we do so with some caution and considerable testing cycles

MAGNETIC ASSEMBLY

Goudsmit UK specialise in the assembly of magnets, and over the last few years we have
developed substantial know-how relating to this field. We can offer the following assembly techniques:

→ Mechanical Assembly
→ Insert Moulding
→ Over Moulding
→ Gluing
→ Heat Staking
→ Ultrasonic Welding
→ Brazing

In order to illustrate the assembly techniques we use, we thought it best to show examples with some application backgrounds.

CAPABILITIES

ULTRASONIC WELDING REPLACES GLUING

In this application the client used two mouldings to house a magnetic assembly. Normally assembled by gluing, the parts often separated due to thermal cycling. Goudsmit UK redesigned the assembly and substituted gluing with ultrasonic welding. The result is a better cosmetic finish and a more stable and durable assembly

 

 

SIMPLE GLUE APPLICATION

The magnet needs to be held on the plate by more than attractive forces. We could have used a mechanical fixing or a heat stake, but the application is non-critical and the client had historically used glue.

 


FDA COMPLIANCE WITH INSET MOULDING

Tasked to combine a magnet and a shaft but not have the magnet come into contact with drinking water, we chose to avoid glue and encapsulate the magnet and shaft, while mechanically coupling them using insert moulding. Cheap, very repeatable and very successful the assembly worked in the application with no issues at all.

 

 

RUBBER BOOTED MAGNET

These magpads are commonly used to hold objects to vehicles. Initial versions featured a rubber boot but later designs moved to a more robust elastomer over moulding.

 

 

 

TWO PART MOULDING ENCAPSULATING A MAGNET

Using an engineering polymer and heat stable pigments, a thin magnet is encapsulated between the layers. The assembly sees 160ºC in operation.
