Refrigerators, air conditioners, and washing machines look like large home appliances.
But inside them, many small die cut parts are quietly doing serious work.
Foam gaskets, rubber pads, adhesive tape frames, PET films, PI films, protective films, non-woven felt, and laminated materials help with sealing, vibration control, insulation, bonding, cushioning, and assembly.
At Sanken, we use precision die cutting to manufacture appliance OEM components from foam, rubber, adhesive tape, films, and converted materials.
These parts are usually hidden.
But when they fail, users may hear noise, feel vibration, see air leakage, or notice poor assembly quality.

Why Appliances Need Die Cut Parts
Appliances use die cut parts because many internal spaces are irregular, narrow, or function-specific.
A refrigerator needs air sealing and insulation support.
An air conditioner needs foam seals around airflow paths.
A washing machine needs vibration reduction and cushioning.
A control panel may need bonding, dust protection, and electrical insulation.
Standard parts cannot always match these shapes.
That is why custom die cut parts are used to fit specific housings, panels, ducts, motors, displays, and electronic modules.
The goal is not only to cut a material.
The goal is to make the appliance easier to assemble and more reliable during use.
Die Cut Parts Used in Refrigerators
Refrigerators need sealing, insulation, cushioning, and surface protection.
Temperature control is important.
Air leakage, vibration, or poor sealing can affect performance and user experience.
Common die cut refrigerator parts include:
| Refrigerator Area | Common Die Cut Parts | Main Function |
|---|---|---|
| Door and cabinet areas | Foam gaskets, rubber seals | Air sealing and cushioning |
| Control panels | Adhesive tape frames, PET films | Bonding and insulation |
| Compressor area | Rubber pads, foam pads | Vibration reduction |
| Interior panels | Protective films, foam strips | Surface protection and gap filling |
| Air ducts | Foam seals | Airflow control |
| Electronic modules | PET films, PI films, foam gaskets | Insulation and dust protection |
For sealing applications, foam gaskets and sealing components are often used to reduce air leakage, block dust, and cushion contact areas.
A refrigerator gasket must compress correctly.
If the foam is too soft, sealing force may drop.
If it is too hard, assembly may become difficult.
If the adhesive backing fails, the part may lift or shift.
That small foam strip can become a very loud quality issue.
Die Cut Parts Used in Air Conditioners
Air conditioners use many foam, rubber, film, and adhesive components.
The most common function is sealing around airflow paths.
If air leaks in the wrong place, the system may lose efficiency or create noise.
Common air conditioner die cut parts include:
- Foam air duct seals
- Rubber vibration pads
- Adhesive-backed foam strips
- PET insulation films
- Protective films for panels
- Non-woven dust filter support parts
- Foam pads for motor areas
- Control panel adhesive frames
- Cushioning parts for plastic housings
Air conditioner parts often need stable thickness and compression.
The foam must seal the gap without blocking assembly.
The adhesive must stay in place under temperature changes and vibration.
The part must also be easy for workers to peel and apply during production.
For high-volume roll materials, roll-to-roll die cutting can help improve consistency for adhesive foam strips, protective films, and tape components.

Die Cut Parts Used in Washing Machines
Washing machines create vibration during operation.
That means die cut parts are often used for damping, cushioning, sealing, and noise reduction.
Common washing machine die cut parts include:
| Washing Machine Area | Common Die Cut Parts | Main Function |
|---|---|---|
| Motor area | Rubber pads, foam pads | Vibration control |
| Housing panels | Foam strips, felt pads | Anti-rattle protection |
| Control panel | Adhesive tape frames, protective films | Bonding and surface protection |
| Door or cover areas | Foam gaskets, rubber seals | Dust and water resistance support |
| Pump and internal modules | Cushioning pads | Shock absorption |
| Wiring areas | PET films, foam tape | Protection and insulation |
Washing machine parts often face repeated vibration.
So material recovery is important.
A pad that works during the first test may fail after long-term compression or movement.
Rubber is often used when stronger damping is needed.
Foam is useful for gap filling and cushioning.
Non-woven felt can reduce contact noise between hard surfaces.
Adhesive Tape Parts for Appliance Assembly
Adhesive die cut parts are widely used in refrigerators, air conditioners, and washing machines.
They help bond panels, position foam gaskets, protect surfaces, and simplify assembly.
Common adhesive parts include:
- Double-sided tape frames
- Foam tape strips
- PET-backed adhesive parts
- Transfer adhesive films
- Protective films with pull tabs
- Adhesive-backed foam gaskets
- Laminated foam and tape structures
Adhesive selection must match the bonding surface.
Appliances may use plastic, painted metal, glass, film, rubber, and textured surfaces.
These surfaces do not bond the same way.
A good adhesive part should peel smoothly, stay flat, bond accurately, and avoid glue overflow.
If workers struggle to remove the liner, assembly speed drops.
If the adhesive lifts after production, quality complaints start.
Film and Insulation Parts in Appliances
Modern appliances use more electronics than before.
Control panels, sensors, displays, motors, power boards, and connectors often need die cut film parts.
Common film materials include:
| Film Material | Common Use |
|---|---|
| PET film | Electrical insulation and separation |
| PI film | Heat-resistant insulation |
| Protective film | Scratch and surface protection |
| Black PET film | Light blocking in display areas |
| Release liner | Adhesive part handling |
| EMI shielding film | Electronic protection in selected areas |
Film parts need clean edges and accurate holes.
Burrs, particles, scratches, curling, or poor adhesive placement can cause assembly problems.
This is especially important in display panels and control modules.
A tiny particle on a visible surface is not tiny to the customer.
Manufacturing Process for Appliance Die Cut Parts
Most appliance die cut parts are made through material converting, lamination, die cutting, waste removal, inspection, and packaging.
For foam processing details, buyers can review how die cutting works from foam rolls to finished parts.
A typical process includes:
| Step | Purpose |
|---|---|
| Application review | Confirm sealing, vibration, bonding, or insulation need |
| Material selection | Choose foam, rubber, film, felt, adhesive, or laminated structure |
| Lamination | Add adhesive, film, liner, or protective layer if needed |
| Tooling design | Prepare the die cutting tool based on drawing |
| Die cutting | Cut gaskets, pads, strips, frames, or films |
| Kiss cutting | Cut adhesive parts while keeping liner intact |
| Waste removal | Remove unused material cleanly |
| Inspection | Check size, thickness, edge quality, and adhesive position |
| Packaging | Protect parts from deformation, dust, and sticking |
For adhesive-backed parts, kiss cutting is very useful.
The gasket or film is cut while the release liner stays intact.
This makes peeling and assembly easier.
Supply Formats for Appliance OEM Production
The delivery format affects how easily parts are used on the assembly line.
Some appliance parts should be supplied in sheets.
Some should be supplied in rolls.
Some should be supplied as kits.
| Supply Format | Suitable Use |
|---|---|
| Individual pieces | Simple assembly or lower-volume projects |
| Sheets | Manual picking and organized assembly |
| Rolls | Automated or high-volume application |
| Kiss-cut on liner | Adhesive foam, tape, and film parts |
| Kits | Multi-part appliance module assembly |
| Trays or bags | Parts needing deformation or surface protection |
For manual assembly, die cut parts supplied in sheets can make picking and placement easier.
For automated application, rolls may improve production speed.
For more detail, this guide explains how die cut parts are supplied in sheets, rolls, or kits for different OEM assembly processes.

Quality Checks for Appliance Die Cut Parts
Appliance die cut parts must be stable from sample to mass production.
A small variation may affect sealing, vibration, bonding, or assembly speed.
Important inspection points include:
| Inspection Item | Why It Matters |
|---|---|
| Dimensions | Ensures correct fit |
| Thickness | Controls compression and spacing |
| Hole alignment | Supports accurate assembly |
| Edge quality | Reduces particles and poor fitting |
| Adhesive position | Prevents bonding failure |
| Liner release | Improves peeling and assembly speed |
| Surface cleanliness | Protects visible and electronic areas |
| Packaging condition | Prevents deformation before use |
The approved sample is only the beginning.
The real goal is stable repeat production.
