Sealing Perfection
Transfer Molding: Innovative Heat Management
We recognize that the efficient management of heat is paramount for solenoid coils’ optimal performance and longevity. To address this critical aspect, we utilize cutting-edge transfer molding techniques. By filling the air spaces or voids within the coil housing around the bobbin with plastic, we enable superior heat transfer from the coil. This process is pivotal in preventing overheating and burnout, which can occur if the inner space remains filled with air. Furthermore, our innovative approach yields additional advantages, particularly in demanding environments like space launches. The plastic infusion not only dissipates heat effectively but also imparts stability to the coil, mitigating the risks of vibration-related damage during rigorous operations.
Aerospace and Commercial Space
Elevating Reliability and Performance
Our solenoids stand as exceptional solutions for extreme conditions and are certified for hazardous locations, making them the unequivocal choice for the aerospace industry. We specialize in designing and manufacturing a wide array of solenoid types, from on/off and position control to proportional and more. As leaders in the field, we understand the unique demands of aerospace and commercial space applications. From custom designs to rigorous testing, our solenoids are meticulously crafted to deliver unmatched reliability, performance, and precision.
Harnessing Electromagnetism:
The Power of Solenoids
A solenoid is essentially a coil of wire wound in a helical (spiral) shape, often around a cylindrical core, typically made of ferromagnetic material like iron. When an electric current flows through the wire winding of the solenoid, it creates a magnetic field.
Here’s how they work:
- Electric Current Flow: When you apply an electric current to the wire coil of the solenoid, electrons begin to move through the wire generating a magnetic field around the coil.
- Magnetic Field: The magnetic field can either attract or repel objects, depending on their magnetic properties and orientation.
- Plunger or Armature: Inside the solenoid coil, there is often a movable component called a plunger or armature. When the magnetic field is generated it exerts a force on the plunger, either pulling it into the coil (if it’s attracted) or pushing it out (if it’s repelled).
- Mechanical Movement: The movement of the plunger can be used to perform various mechanical actions. For example, in a door lock or a valve, the movement of the plunger can engage or disengage a mechanism.
- Control: By controlling the amount of current flowing through the coil, you can control the strength of the magnetic field.
