What Is an OEM Solenoid?

An OEM solenoid is a solenoid designed and manufactured specifically for an original equipment manufacturer's product or application.

Unlike an off-the-shelf solenoid, an OEM solenoid can be customized according to the actual requirements of the equipment, including:

• Solenoid dimensions

• Mounting structure

• Plunger size and stroke

• Pull or push force

• Operating voltage

• Coil resistance

• Power consumption

• Duty cycle

• Response time

• Spring force

• Connector and terminals

• Materials

• Operating temperature

• Expected operating life

For OEM projects, the solenoid is normally designed as part of the complete product rather than selected as an independent standard component.

This allows the solenoid to be optimized for performance, reliability, installation space, power consumption, and production cost.

OEM Solenoid Manufacturing for Your Product

At Nextcore, we work with OEM customers from the early engineering stage through volume production.

Whether you already have a proven solenoid design or are developing a new product, we can provide different levels of support.

Existing Solenoid Sample

If you already use a solenoid and need a new manufacturer, providing a sample is often the fastest way to start.

Our engineers can evaluate the sample and analyze its:

• Dimensions

• Coil

• Plunger

• Spring

• Magnetic structure

• Mounting structure

• Electrical specifications

• Mechanical movement

We can then develop a corresponding OEM solenoid for your application.

Existing Drawing

If you have a 2D or 3D drawing, send us the drawing together with your electrical and mechanical requirements.

Our engineers can review the design and provide feedback on manufacturability, materials, coil design, force requirements, and production considerations.

Existing Solenoid but Need Improvement

If your current solenoid works but has problems such as:

• Insufficient force

• Excessive heat

• High power consumption

• Excessive noise

• Short operating life

• Slow response

• Large installation space

• High manufacturing cost

we can evaluate the existing design and develop an optimized solution.

New Solenoid Project

If you are developing a new product and do not have a solenoid design yet, we can work from your application requirements.

Useful information includes:

• Required voltage

• Required force

• Stroke

• Available installation space

• Operating frequency

• Duty cycle

• Expected lifetime

• Working environment

• Target production quantity

Based on these requirements, our engineering team can recommend a suitable solenoid structure and develop a prototype.

Our OEM Solenoid Development Process

A typical OEM solenoid project follows the process below:

1. Requirement Review

We first understand your application and technical requirements.

Typical requirements include voltage, force, stroke, dimensions, duty cycle, lifetime, installation conditions, and production quantity.

2. Sample or Drawing Analysis

If you provide an existing solenoid sample or drawing, our engineers evaluate the mechanical and electrical design.

For projects based on an existing sample, sample replication can often provide a practical starting point for development and quotation.

3. Solenoid Design

The solenoid design may involve optimization of:

• Coil

• Wire size

• Turns

• Plunger

• Magnetic circuit

• Air gap

• Spring

• Housing

• Mounting structure

The goal is to achieve the required force and movement while considering power consumption, temperature rise, lifetime, and manufacturing cost.

4. Prototype Development

After the design is confirmed, we produce initial prototypes for testing.

Prototype testing may include electrical, mechanical, dimensional, force, stroke, temperature, and functional performance checks depending on the project.

5. Design Optimization

Prototype testing may reveal opportunities to improve:

• Force

• Stroke

• Response

• Temperature

• Noise

• Power consumption

• Mechanical reliability

• Manufacturing cost

The design can then be adjusted before mass production.

6. Small-Batch Trial Production

For projects requiring further validation, a small production run can be used to verify the manufacturing process and product consistency.

7. Mass Production

After the design and production process are approved, we move to volume production with defined manufacturing and quality-control procedures.

OEM Solenoid Design Capabilities

Custom Voltage

We can develop solenoids for different electrical requirements, including commonly used DC and AC voltages.

Typical requirements may include:

12V DC, 24V DC, 36V DC, or other specified voltages.

For AC applications, different voltage and frequency requirements can also be considered.

The actual coil design is determined according to the required voltage, resistance, power, force, duty cycle, and operating conditions.

Custom Force and Stroke

Solenoid force is closely related to the magnetic circuit, air gap, plunger geometry, coil design, and stroke.

For OEM projects, we can optimize the solenoid according to your required:

• Initial force

• Holding force

• Stroke

• Pull force

• Push force

• Spring load

• Operating position

If the solenoid is installed vertically, gravity and spring reaction may also need to be considered during design.

Custom Coil Design

The coil is one of the most important components of a solenoid.

We can customize coil characteristics according to the application, including:

• Wire diameter

• Number of turns

• Coil resistance

• Power

• Voltage

• Coil dimensions

• Insulation requirements

• Terminals

• Connection method

Our coil manufacturing capability allows the electrical design to be coordinated with the mechanical and magnetic requirements of the complete solenoid.

OEM Solenoid Manufacturing

OEM manufacturing requires more than simply assembling standard components.

The production process can include:

Coil Winding → Component Manufacturing → Plunger Processing → Housing Manufacturing → Assembly → Electrical Testing → Functional Testing → Final Inspection

Depending on the product, manufacturing may involve:

• Automatic coil winding

• Metal stamping

• CNC machining

• Plastic injection molding

• Component assembly

• Coil assembly

• Electrical testing

• Mechanical testing

• Functional testing

Manufacturing processes are selected according to the solenoid structure, production volume, tolerances, and cost requirements.

OEM Solenoids for Different Applications

Nextcore develops custom solenoids for a wide range of applications.

Smart Locks

Solenoids can be used for locking, unlocking, latching, and mechanical actuation.

The design may need to balance force, stroke, spring preload, power consumption, noise, and operating lifetime.

Vending Machines

Solenoids can be used for dispensing, locking, feeding, and mechanical control mechanisms.

Compact size, reliable operation, fast response, and long operating life are common requirements.

Medical Equipment

Medical equipment may require compact, low-power, low-noise, and reliable solenoid solutions.

Solenoid valves can also be developed for fluid and air control applications.

Industrial Automation

Solenoids can provide linear or rotary mechanical movement in automation equipment, sorting machines, control mechanisms, and industrial machinery.

Automotive Equipment

Automotive solenoid applications may require specific voltage, temperature, vibration, lifetime, and environmental performance.

Household Appliances

Compact solenoids and solenoid valves can be designed for switching, locking, dispensing, fluid control, and other electromechanical functions.

Custom OEM Solenoid vs Standard Solenoid

A standard solenoid can be suitable when the application matches an existing specification.

However, OEM projects often have specific requirements that cannot be fully satisfied by an off-the-shelf product.

For a new product, an OEM solenoid can be designed around the actual mechanical and electrical requirements of the equipment.

OEM Solenoid Cost Considerations

The cost of an OEM solenoid depends on more than the size of the product.

Important cost factors include:

• Copper wire

• Magnetic materials

• Housing materials

• Plunger

• Spring

• Machining requirements

• Stamping or molding

• Assembly

• Testing requirements

• Tooling

• Production quantity

• Packaging

For high-volume OEM projects, the design can often be optimized for manufacturing efficiency.

For example, changing the component structure, manufacturing process, material selection, or coil design may reduce production cost without simply reducing product quality.

Our goal is to find a practical balance between performance, reliability, manufacturing efficiency, and target cost.
