3DZWMAN Heat Set Insert Tool Kit with 370PCS Brass Inserts & Soldering Iron | M2-M8 Thread Sizes

• The base is made by bending and welding sheet metal, and reinforced welding is added at the bottom, equipped with anti slip foot pads. The Z-axis is a widened 2040 aluminum profile, which provides sufficient strength when the structure is pressed down. Three large V-shaped pulleys are tightly matched with the 2040 aluminum profile, and only one V-shaped pulley needs to be adjusted to clamp the aluminum profile. The metal tension spring can be used repeatedly without deformation, and it is easier to adjust the insertion height by hand tightening the nut
• The digital soldering iron supports automatic voltage conversion of 110V/220V. Long press the # switch, with a temperature range of 180 ℃ (356 ℉) -500 ℃ (932 ℉). Long press the+- button to continuously adjust the temperature, and comes with a soldering iron tip and silicone protective cover
• Insert Tips M2 M2.5 M3 M4 M5 M6 (1/4) M8 can match the electric soldering iron of ceramic tube D4xL24 on the market

• It can be used for 3D printing Heat-Set Insert Installation and plastic parts to keep 90° vertical insertion

• Prepare the Plastic Part — Ensure your 3D printed part has pre-drilled holes designed for heat set inserts. The hole diameter should be slightly smaller than the insert's outer diameter for a snug fit. Clean any debris from the holes.
• Set Up the Soldering Iron — Select the appropriate insert tip for your chosen brass insert size. Attach it to the digital soldering iron and set the temperature between 180℃-500℃, adjusting based on the plastic type (e.g., lower for PLA, higher for ABS). Allow it to heat up.
• Install the Insert — Align the brass insert with the pre-drilled hole, ensuring it's perfectly vertical. Gently press the heated soldering iron tip onto the insert. Apply steady, even pressure until the insert is seated flush with the plastic surface. Avoid excessive heat to prevent melting the plastic excessively.
• Cool and Test — Allow the plastic to cool and solidify around the insert. Once cooled, carefully remove the soldering iron. Test the thread by screwing in the appropriate machine screw to ensure a secure and smooth fit. Repeat for all required inserts.
