Plastic Welders and its use

Plastics are synthetic or semi-synthetic compounds that can be easily malleable. That means it can change shape.

Plastic is harmful to our environment, as they are kind of indestructible. So people are encouraged to use any alternative to plastics or use more natural biodegradable versions.

The plastic that we will discuss in this article is thermoplastic. They can be melted with heat, and when cooled down, it return to a solid-state. Some plastics are heat resistant than other ones.

Plastic welding is a process where two or more edges of a thermoplastic are melted using heat. This process has three stages:

  • Surface preparation
  • Apply heat and pressure
  • Cooling down

Getting a plastic welder needs good skills, the right kind of tools, and the plastic product. We have included a plastic welder that is suitable for beginners and professionals both.

Things to consider before buying a plastic welder

Buying a plastic welder is a difficult job. You need to assure about the quality plus the effectiveness. You will need something that delivers the work accurately. So, you need to invest carefully.

Here are some factors that you may consider before buying a plastic welder:

Heating Type:

You will find mainly three types of plastic welders in the market. Airless or contact welders, heat guns, and high-frequency models.

Airless models come with a tip. It is used to melt the plastic properly. Airless plastic welders can’t fix the structural integrity of any plastic material.

Heat guns provide hot air that helps to melt plastics. Welding guns help to soften the plastic material and create a stronger bond.

It makes the product long-lasting. The High-frequency model produces ultrasonic waves to melt the plastic. So, it can do structural repairs.

Power capability:

Power is also an important thing to consider. Welders have high power efficiency, and they can be used to work on hard plastics. Welder with 200W capacity can be used to melt hard plastics.

For repairing cracks and fixing the surface, it is better to use welders with high power efficiency. Airflow is also essential in a plastic welder.

If the welder has poor airflow, then it will take longer to work. The heating element will burn, and it can also damage the welder.

Type of plastic:

There are three types of plastic welding techniques; tack, speed, and pendulum. Each of these techniques is used in different kinds of plastics. 

You will find different types of nozzles. Choose the one from various choices like; pencil tip nozzle, flat slit nozzle, triangle welding nozzle, etc.


Not everyone needs a high powered welder. If you are fixing home stuff not so often, then buy something with less power. If you want something for professional use, then buy a high–powered plastic welder.
