Plastic Housing WeldIf you’re looking to achieve precise and clean cuts on plastic materials, look no further than the Iso-Tip 7700 Soldering Iron. This versatile tool, commonly used for soldering electronic components, can also be used for tasks precision cutting on a variety of materials. We had a customer that we build a product for in one of our other divisions. The drawing called out a small bleed hole. After we made the parts the customer decided they didn’t want the small hole. The customer was out of the country. Shipping the parts back to rebuild them was not a great option; or at least it would have cut into my year-end bonus a bunch.

For plastic cutting, or welding, using a fine point or a knife type tip works best. The fine points allows for intricate cuts, while the knife tip is ideal for broader straighter edges. For this application we used our flat knife like tip – chisel tip on the 7700 cordless soldering iron to weld the hole closed. We offer a wide range of compatible tips to suit your specific cutting needs, which can be found here.
