      Can plastic be welded?

      Yes, plastic can be welded. This is one of the common questions, every Leister member is asked while explaining Leister product.

      How do you weld plastic?

      Plastic can be welded in so many ways with the aid of hot air, infrared, hot wedge, and laser. Plastic welding is a process of joining two parts together under the right amount of temperature, pressure, and speed. Most of the thermoplastics (PP, PE, PVC, HDPE, LDPE, PPR, MDPE, etc.) can be welded by melting the surfaces and pressing them together. Once cooled down, the welded area is twice stronger than the other places. Please note that only similar material or same type (PP to PP or PE to PE or HDPE to HDPE) can be welded. It is important to know the material that you intend to weld.

      Is it safe to Weld Plastic?

      Plastic welding provides a permanent solution. Glue reduces the life of plastic sheets and can cause damage. On the other hand, welding increases the strength of the plastic material. Welding prevents dust accumulation and damage to the material. Be sure you are in a well-ventilated area, pre-heat your gun for at least 2 minutes, make sure your surfaces are clean and double check what type of plastic you are welding.

      How long will it take to weld a product?

      This totally depends on the application, your ambient temperature, characteristics of the welding material and so on. Every welding process takes due time and it is also important to give sufficient cooling time after welding for the bonding to strengthen.

      Is plastic weld commonly used?

      Will you believe if we say that majority of flooring you see in trains, buses, hospitals, are plastic welded. If plastic flooring is welded, they increase the life and durability of the material resulting in less maintenance. Also, repairing a plastic item like car bumpers, crates, bins, etc. instead of throwing them away reduces the impact of plastic reaching landfills. Repair and Reuse will save your pocket and environment.

      There are a variety of plastics that can be welded, such as PP (Polypropylene), HDPE (High Density Polyethylene),

      Are there techniques in welding plastic?
