Permanent magnets are a favorite among designers because they can be incorporated into many products, giving them a unique value.

So, magnets are pretty common in plastic stuff.

But making them stick to plastic, especially when there’s a bunch of them, can be a bit tricky.

WHAT TECHNIQUE DO YOU USE TO STICK THE MAGNET ON THE ABS PART?

How to Glue Magnets to Plastic (ABS, Acrylic, TPE, PET, TPU, Silicone, Nylon)

There are different methods to embed a magnet into plastic, like over-molding, insert molding, ultrasonic welding, using glue, snap design and more

When it comes to the best way to attach magnets to plastic, there isn’t a one-size-fits-all solution. Each approach has its strengths, and the best one depends on the particular situation or needs.

Sometimes, a combination of methods is needed to securely fasten the magnets. Designing the plastic with snap-fit features can be more convenient in certain cases. In other situations, using ultrasonic welding might enhance the bonding strength and improve the seal between the plastic and magnet. Additionally, complete encapsulation may offer greater convenience in specific scenarios.

But getting glue to hold magnets on plastic is a popular and simple choice. Here, we’ll focus on discussing the method involving glue and how to glue magnets to plastic firmly.

ANY SPECIFIC GLUE FOR MAGNETS AND PLASTIC? WHICH GLUE TO CHOOSE?

We, as folks who supply magnets, get asked a lot by our customers: ” What kind of adhesive can I use to stick magnets to plastic?

When picking glue, the most crucial thing to think about is how well it sticks (really strong bond), doesn’t come off easily if dropped at different heights, and will the glue turn yellow or white. After that, it’s about whether it dries quickly, how easy it is to apply, and if it can handle hot and cold temperatures. Also, consider the glue’s color, how much area it needs to stick, and if it suits the flexibility needed for the surfaces you’re bonding, among other things.

Here are several types of adhesives suitable for bonding magnets to plastic:

  • AB structural glue
  • Epoxy potting glue
  • TPU magnet glue
  • Magnet silicone adhesive
  • Highly transparent UV glue

From the past experience that gluing metal to plastic can fail in the process if the glue is not right. That’s why, before diving into specific procedures, you’d better to seek guidance from adhesive experts. For larger-scale bonding needs, adhesive manufacturers can even offer customized adhesive services tailored to particular requirements.

HOW TO GLUE YOUR NEODYMIUM MAGNETS ONTO PLASTIC?

Gluing neodymium magnets to plastic is pretty straightforward. The steps involve cleaning the bonding surfaces thoroughly, applying the adhesive on plastic, placing the magnet where it needs to go, and then allowing the glue to dry undisturbed, and finally done.

Handling a large volume of magnet adhesive assembly work, even with simple and repetitive steps, can indeed become quite tricky. But worry not, professional companies usually have their own tricks up their sleeves to manage this effectively.

For standard products, factories often use something called a “glue dispenser.” These machines are really precise, spreading glue evenly and cutting down on wastage. They’re great because they reduce the amount of labor needed and the overall production costs, while also significantly boosting how much gets made in less time.

But when it comes to making custom products, it’s usually best to have skilled technicians handle the glue dispensing. Doing it by hand might lead to more mistakes, inconsistency, and a lot of material going to waste. So, it’s not just about having experts choose the right glue. The actual process of putting the glue together also needs skilled professionals who know what they’re doing.

Of course, if you’d rather skip all the hassle of applying glue, you can simply opt for adhesive-backed magnets. Just peel off the sticker and stick the magnet directly onto the plastic surface.

When using adhesive-backed magnets on plastic, if the plastic surface isn’t smooth, it might lead to poor contact areas where the adhesive doesn’t fully cover. In such cases, it’s better to avoid using thin adhesive and switch to a thicker adhesive instead.
