Getting the Most from Heated Nut Insertion

Hot nut insertion is the process of inserting a threaded nut into a plastic part. There are three main technologies for related applications: inductive heating, conductive heating and ultrasonic insertion. Pairing six-axis robots and integrated quality controls with this technology allows for accurate, repeated insertion of heated nuts into parts of all configurations.

Vibratory Bowl

Vibratory Bowl

Runs the nuts through to ensure the correct part of the insert is fed through every time.

Inductive Heating Coil

Inductive Heating Coil

Nut Insertion Head

 

Nut Insertion Head

Sensors guide the head to ensure precise insertion. The head also internally and externally cools the nut upon completion of installation.

SCARA Robot

SCARA Robot

The robot picks the heated nut and directs it into its precise insertion.

Custom Fixture with Sensors
 

Custom Fixture with Sensors

Holds part in place so that machine can precisely insert nut into the plastic part.

Light Curtains
 

Light Curtains

To ensure safe run over time, the front light curtains will stop the machining process if it detects the operator.

Emergency Stop and Reset Button

Emergency Stop and Reset Button

Lets the operator control the machine and stop if necessary.

Cycle Start Touch Sensor
Cycle Start Touch Sensor

Cycle Start Touch Sensor

Responds to a finger blocking light rather than to pressure to ensure a safe start every time.

We are the Nut Insertion Experts

Our nut insert platforms are some of our most popular standard products. There are three primary functions that the machine performs to create great parts consistently: Nut singulation, Heating, and Transport/insertion. Our NI platform allows us to be able to commit to a ±0.2mm tolerance on the nut insertion. We can commit to this standard because of the high accuracy and repeatability of the Epson robot and our AMS nut insertion head that is able to create consistent insertions across part variability due to the dynamic, adjustable positioning sleeve.

Inductive hot nut insertion

Inductive hot nut insertion involves heating the nut in a magnetic field produced by an inductive coil.

Conductive Heating

Conductive heating is the process of either pre-heating the plastic prior to insertion, or partially inserting the nut and heating both the plastic and the nut directly via a heated probe.

Ultrasonic insertion

Ultrasonic insertion uses a sonotrode that contacts the insert directly to generate heat through friction.
