Loudspeaker adhesives for fast assembly

October 23, 2023October 23, 2023 CTA

A range of loudspeaker adhesives are available from Central Tapes & Adhesives Ltd. Go from parts and pieces to power test in 10 minutes! As Hernon’s UK & European technical specialists we can advise on a complete range of adhesives for speaker assembly.

Our adhesives are available in a range of formulations that are designed to bond different types of materials, including metals, plastics, and composites. The adhesive is applied to the mating surfaces of the speaker components and then allowed to cure, forming a strong and durable bond.

The process of building a speaker using loudspeaker adhesives typically involves assembling several components, including the pole piece, magnet, top plate, basket, voice coil, spider, cone, surround, and dust cap. The adhesive is used to bond these components together in a precise manner to ensure that the speaker functions correctly.

To use loudspeaker adhesives to build a speaker quickly, it is important to choose an adhesive that cures quickly but still provides a strong bond. A good example is Hernon’s Quantum 134 adhesive which is designed for use with loose-fitting parts such as cones and dust caps. Another example is Hernon’s Quantum 135 adhesive which is designed for use with tight-fitting parts such as voice coils and spiders.

When using loudspeaker adhesives to build a speaker quickly, it is important to follow the manufacturer’s instructions carefully. This typically involves applying a thin film of primer to the mating surfaces of the components before applying the adhesive. The components are then mated together with a twisting motion to ensure that the adhesive is spread evenly across the mating surfaces.

Our range of speaker adhesives are essential in the speaker assembly or repair process, providing a strong and durable bond between the various components and providing quick assembly times. Here is some guidance for product usage.

Pole piece to magnet – Magnet to top plate – Top plate to basket

Product benefits

Easy to use
Non-flammable, low toxicity
One component
Works on damp, rusty metals
Replaces conventional primers for most industrial finish paints

Surface preparation on old steel

Loose of “flaky” rust must be removed. Only conversion of firmly bonded rust will result in durable protection. Oil, old paint, grease, mill scale, fingerprints and water soluble surfaces and chlorides must be removed to allow Rust Eliminator 32 to react with the rust. Loose rust, oil paint and mill scale should be removed preferably by power wire brushing, followed by rinsing with water to remove powder and soluble. Manual wire brushing, chipping, scraping and particularly roto peening can also be used. Oil, grease, form oil and fingerprints should be removed before loose rust. Ideal surfaces will show light rust as well as bare metal surfaces. Rust Conversion Time and Appearance Two coats of Rust Eliminator 32 are recommended.

On lightly rusted steel (that has been wire brushed), the first coat will start to develop a violet colour within 60 seconds. This will become satin to flat black in appearance. The second coat should dry to a satin black appearance. On heavily rusted steel (that has been wire brushed), the first coat should develop a purple-black colour within seconds. The second coat should dry to a black colour with gloss varying from flat to satin. The second coat should be applied within 15-30 minutes of the first coat.

Advantages of structural adhesives

Structural adhesives are cost effective and will help cut manufacturing costs by reducing the number of mechanical fasteners, spot welds and filler metal required to create a joint or attach two substrates. Adhesive joint design.

In the manufacturing process, adhesives are generally hidden between two substrates, which can offer aesthetic improvements over welding and mechanical fasteners. An adhesive bonded joint will result in a smooth, clean surface, which requires minimal surface preparation prior to final finishing. Therefore, manufacturers can eliminate labour intensive finishing costs such as sanding off imperfections from spot welding.

A huge superiority to advanced product design is that adhesives can be pre applied to parts otherwise inaccessible to mechanical fastening or welding during the assembly process. This revelation enables engineers not to be bound in their innovation of design by previous obstacles such as space or accessibility. An additional benefit is the reduction in the amount of time it takes to join substrates. Welding or installing mechanical fasteners is generally more time consuming compared to using a structural adhesive.

Structural adhesives excel in joining dissimilar substrates and materials with different thicknesses. Adhesive compensates for the differences in expansion and contraction in dissimilar materials. High performance structural adhesives can form resilient bonds and maintain strength over a wide range of temperatures.

Adhesives have the ability to eliminate stress concentration caused by spot welds, rivers, screws, and other mechanical fasteners while maintaining surface integrity. Where as a rivet or screw hole in a substrate concentrates the stress at the hole, which can potentially decrease the physical properties of the substrate, adhesives spread the load over the entire bonded area. Visit adhesive stress loads.

Using structural adhesives can reduce the weight of finished product or structure because less welding metals and mechanical fasteners are used. Additionally, eliminating screw holes and rivets in the assembly process enables manufacturers to utilise thinner, lighter materials without concerns of distortion, splitting, or crazing at the mechanically fastened site. An added benefit of eliminating the holes in metal is that it can also reduce the chance of rust and corrosion.

Unlike welding, structural adhesives have the ability to maintain the integrity of the bonded materials because there is no metal distortion or weakening due to heat when using adhesives. Structural adhesives can also increase the stiffness of structures and provide the necessary fatigue and force resistance.

Adhesive vs welding and mechanical fixing –

Who is choosing structural adhesive?

The answer is “everyone”. New applications are being developed and tested daily. Reports from the agricultural industry show workers are repairing metal fences using structural adhesives instead of welding. Marine industry manufacturers are bonding parts using structural adhesives in applications that require high resistance to chemicals like kerosene, hydrocarbon oil, mineral spirits, and ethylene glycol. The automotive industry is moving away from rivets in favour of structural adhesives due to a combination of corrosion resistance, stress relief and cost reduction. Aerospace engineers were among the earliest industries to adopt structural adhesives, mainly because adhesives can create seals that keep water out of metal fabrications while providing corrosion protection.
