The open frame type electromagnet plays a very important key in the industry. It is a basic electrical appliance and is known as the “King of Electrical Appliances”. Due to its simple structure and low cost, it is widely used in automation equipment.
The open frame type frame type electromagnet is mainly composed of a magnetic iron shell, a coil skeleton, an armature (sliding rod) and a fixed iron core.

The features of solenoid used in dispenser selling machine as below:
Stroke Distance and required force.
The power of wattage consumption
The life of cycling time
The working environment
The dimension of the solenoid
The performance of the solenoid

Let’s take The frame push-pull solenoid used in a vending machines , for example. Inside this machine, the push-pull solenoid work to control the different levels of product during the selling

Hot & Cold Environment Testing
Through our hot & Cold environment machine to Improve the product adaptability for heat and cold pressure, speed, humidity, corrosion to meet the base requirement.

Metal Material Testing
Based on client’s demand and Dr. Solenoid’s specification, all of the metal material will do the Salt spraying testing, hardness testing and plating surfacing testing and other necessary report.

Performance testing
We will do all of the performance of electromagnet and solenoid valve lifespan testing, Stroke distances stable, force testing….and etc.

Product Reliability
Via the test fixture and high precision testing equipment, we offer data-based verification report to analyze and enhance the product reliability.

Final Inspection
In response to the accuracy demand for medical equipment, all of the medical solenoid valves must pass the final inspection and product process control; in this way, we could indeed guarantee the product reliability and stability.
