Modern appliances depend on durable, high-performance components to operate reliably and springs are at the heart of many essential mechanisms. From refrigerator doors to washing machine drums, appliance springs are used to apply force, absorb shock, control movement, and return components to their resting positions.
At Wermke Spring, we manufacture custom springs for OEM appliance manufacturers and component suppliers across the country. Our experience in helping engineer and producing springs for consumer and commercial appliances ensures long-lasting performance and compliance with exact technical specifications.

What Are Appliance Springs?
Appliance springs are mechanical springs integrated into residential and commercial appliances to provide consistent force, movement, and mechanical resistance. These springs must offer repeatable performance over thousands, or even millions, of cycles, often under conditions involving heat, moisture, vibration, or chemical exposure.
Appliance springs can be found in almost every household device, and their role is often invisible to users, but absolutely critical to performance.
How Springs Are Used in Appliances
Springs are used in the appliance manufacturing industry for a wide range of functional and ergonomic applications. Some of the most common uses include:
Door Closing and Balancing
- Refrigerator and oven doors: Torsion or extension springs help provide smooth opening and closing.
- Dishwasher doors: Tension springs assist with the door’s counterbalancing action, providing a controlled descent and return.
Drum and Agitator Suspension
- Washing machines and dryers: Compression springs help isolate vibration, stabilize rotating drums, and absorb shock loads during spin cycles.
Latching and Locking Mechanisms
- Microwaves and ovens: Torsion and wire form springs apply pressure to door latches and safety interlocks.
- Top-load washers: Latching mechanisms utilize small precision springs to maintain secure closure.
Detergent and Dispenser Systems
- Dishwashers and washers: Compression springs control the movement of detergent dispensers or softener drawers.
Switches and Contacts
- Control panels and buttons: Extension or compression springs provide tactile feedback in switches and enable repeated actuation.
Types of Springs Used in Appliances
The type of spring used depends on the application’s force requirements, motion profile, spatial constraints, and operating environment.
Compression Springs
- Absorb load or pressure
- Used in suspension systems, dispensers, and push-button assemblies
Extension Springs
- Provide pulling force
- Found in dishwasher and oven door systems
Torsion Springs
- Apply torque or rotational resistance
- Common in appliance hinges and latches
Wire Forms and Flat Springs
- Custom-shaped to fit unique assemblies or moving parts
- Found in control interfaces, switches, and contacts
At Wermke Spring, we custom manufacture each spring to match the required load, deflection, dimensional envelope, and durability needs of your application.
Material Selection for Appliance Springs
Springs used in appliances must resist fatigue, corrosion, and, depending on the appliance, high heat or moisture.
Common materials include:
- 302/304 Stainless Steel – Excellent corrosion resistance for moist or food-contact environments
- 316 Stainless Steel – Higher corrosion resistance for marine or high-humidity settings
- Music Wire – Cost-effective and strong for dry, indoor applications
- Phosphor Bronze or Beryllium Copper – Used in electrical contacts or where non-magnetic materials are required
- Oil-Tempered and Chrome Silicon – Suitable for high-load or high-cycle parts
All materials are available with optional coatings, plating, or passivation to improve corrosion resistance and cosmetic finish.
Appliance Spring Design Considerations
Each appliance application presents unique engineering challenges. Our team considers factors like:
- Cycle life – Springs must withstand frequent use without fatigue
- Temperature exposure – Ovens, dryers, and dishwashers may operate at elevated temperatures
- Corrosion resistance – Many appliances are exposed to water, humidity, or cleaning agents
- Quiet operation – Springs must avoid squeaking, rattling, or resonance
- Compact design – Springs often fit into tight or hidden assemblies
We work with appliance manufacturers to optimize spring geometry, material selection, and finish for the best balance of cost, performance, and durability.
Frequently Asked Questions
What spring types are most common in appliances?
Compression and extension springs are the most widely used, followed by torsion springs in door and hinge applications. Wire forms are also common for control mechanisms.
How long should an appliance spring last?
A well-designed appliance spring should withstand tens of thousands to millions of cycles. Longevity depends on material, design tolerances, and environmental exposure.
Can you make springs for both residential and commercial appliances?
Yes. We manufacture springs for everything from consumer-grade dishwashers to industrial kitchen equipment, vending machines, and laundry systems.
What if I only have a sample spring, but no drawing?
No problem. We offer reverse engineering services to replicate and improve existing springs, even from worn or broken samples.
Do you support high-volume OEM production?
Yes. Wermke Spring supports both small batch and large-scale manufacturing with consistent quality and just-in-time delivery options.
