Hot melt automotive

Your products might need a system where gluing the parts together should be a reliable process. The demand is even greater when we’re talking about transportation vehicles and other heavy equipment. Safety for the product’s users is the primary concern. So with this, let’s explore the considerations to check if we’re turning to a company for a reliable adhesive technology, including if you need the right systems for hot melt automotive industries require.

Efficient Process where Durability is Maximized, Time is Minimized

The past years have proven that elevating engineering methods, adopting cost-effective & even green materials, and simplifying manufacturing as well as marketing processes are always better when it comes to the automotive industry. And so it is also wise to decide based on these aspects when it comes to bonding of your product’s parts.  Your partner supplier should be a sure candidate when it comes to offering an adhesive application automotive strategy that is less demanding on time and process.

Of course, as this is about hot melt adhesive (HMA) and other similar technologies, this is a different thing from adjoining parts through altering the product’s design itself or welding parts together into one part. We are talking about gluing components like mirrors, carpets or seats and in assembling these in an equipment, the conditions in setting up the gluing material are distinct. These should be just right for the machine – that means standards “higher” than for example, gluing together shoes or bottle labels.

Talk to your supplier about the stages involved in a hot melt automotive products’ application for your particular case. Ask how long it takes for a batch of products to complete the process. Are there disrupting stages in the production cycle where manual quality monitoring will be needed, or can these bottlenecks be addressed by automating them somehow by you or them? Assess these concerns for the best productivity.

The Right Machine

Any adhesive application vehicle manufacturing companies apply now will need a suitable hot melt machine to complement its engineering requirements. This can involve the following for the application of hot melt automotive manufacturers now need:

  • Setting the right temperature to adjust to the desired viscosity of the glue.
  • Transfer of the adhesive material by utilizing liquid displacement methods that preserve the quality of the glue, at the same time using less energy (this is often determined on the consumption of energy on the molten material per-kilo). This involves good pneumatic methods like using piston pumps.
  • Method of distributing the glue to a material, which can be through spraying, lines or patterns, or coating.
  • Eliminating volatile compounds to achieve the desired consistency and durability.
  • Applying the necessary frequency of distributing the adhesive material before the final coating. Coating offered by the Micron series hotmelt, for example, can range between 350 and 1050mm for their hot melt cars systems.
  • Drying of the adhesive where it should be a careful process to achieve maximum durability.

How HMAs are applied in vehicles’ manufacturing

Adhesive formulations derived from polyamides make reliable applications to resist electric conduction, gasoline or oil. They are used well in wood and metal. Materials like polyurethanes a.k.a TPU’s (for thermoplastic polyurethane) have a more elastic characteristic and are compatible with plastic resins. Ask your manufacturer about the sealant or adhesive formulas they may apply for your products. Adhesion for vehicles is usually required in:

  • combining soft materials including foam, fabric, and leather with the car’s basic structures
  • insulation and sticking together of metal parts
  • parts that need more flexibilty and less friction
  • glass to stick to other materials
  • vehicle parts like speakers, pedals and water pumps
