What is Film Press Processing?

Film press processing is a technique that uses dedicated molds to punch out desired shapes from relatively low-hardness materials such as double-sided tape, film, cushion, and metal foil in roll or sheet form.
Depending on customer requirements for cost, quality, and delivery time, we select the optimal processing method, either roll or sheet, and propose the best processing method.

This method involves pressing a mold called a cookie cutter or pinnacle mold against the material to cut it, just like cutting cookie dough with a mold.

This processing method is known as “punching,” “die-cutting,” or “cutting,” and it boasts high reproducibility and mass production capabilities.

By using different processing methods such as full cut (cutting including the backing paper) or half cut (leaving the backing paper), we can ensure usability and manageability of the products.

This technique is applicable to various shapes and sizes and is utilized in fields such as electronic components, medical, automotive, and optics.

Films Used in Press Processing

Films used in press processing are mainly thin sheet materials based on plastic or metal.

In the case of plastics, PET (Polyethylene Terephthalate) and PC (Polycarbonate) are representative, while aluminum and copper foil films are typical for metals.

Nichibei Parts also handles graphite sheets as heat dissipation materials, among other diverse film materials.

These films come in a variety of types depending on the application, such as decorative films used for decorative purposes and functional films that enhance weather resistance and stain resistance.

Molds Used in Film stamping and machining

Various molds are used in film punching processing according to the purpose and precision required:

Success Points and Precautions in Film Press Processing

To succeed in film press processing, material selection, mold accuracy, and optimization of processing conditions are important.

First, the film to be processed must be selected based on the required specifications, with excellent heat resistance and elasticity suitable for the purpose.

Next, the accuracy and surface finish of the mold directly affect the final product, so high-quality molds are essential.

Additionally, processing conditions such as pressure, temperature, and time need to be finely adjusted according to the type and thickness of the film.

To prevent wrinkles, bubbles, misalignment, burrs, and sagging during processing, jig design and setting are also indispensable.

In the manufacturing process, it is also important to include inspection processes using inspection equipment to detect and respond to defects early.

These points are key to successful film press processing.

Choosing a Contractor for Film Press Processing

When outsourcing film press processing, it is important to choose a contractor based on three points: achievements, responsiveness, and equipment.

First, check if the contractor has extensive experience with the film materials and processing methods you want to process.

First, check if the contractor has extensive experience with the film materials and processing methods you want to process.

Next, check if the contractor can consult from the design stage.

Contractors with know-how from the design stage can help prevent problems and improve quality.

Additionally, if you are considering mass production, check if the contractor has equipment capable of precise mold manufacturing and mass production.

Also, check if the contractor can flexibly respond to small lots and short delivery times.

Choosing a reliable contractor based on these points will lead to stable production of high-quality films.

Other Film stamping and machining Technologies Besides Press Processing

Here are some common film stamping and machining technologies besides press processing:

 Laminating Processing

Laminating processing is a method of bonding multiple films or sheets together using heat or adhesives to form a single unit. It is used in various fields such as packaging, displays, and building materials.

In film stamping and machining, it is used to protect the surface, add functionality, and improve aesthetics.

PET and PP films are commonly used, and material selection is necessary according to durability and application.

 Slitting Processing

Slitting processing is a method of cutting large roll films into narrow strips according to the application and product size.

In film stamping and machining, it is often used as a finishing process after laminating or press processing, for size adjustment and subsequent processing.

It can handle various materials such as PET, aluminum, CPP, and is used in packaging, electronic components, medical applications, and other fields.

 Etching Processing

Etching processing is a method of partially dissolving or removing the film surface using chemicals or lasers to form fine patterns and textures.

In film stamping and machining, it is used for decoration and functional addition.

Especially in applications requiring high precision, such as electronic components and displays, precise methods called photo etching are used.

 Sandblasting Processing

Sandblasting processing is a method of forming textures and patterns on the film surface by blowing fine abrasive materials at high pressure.

In film stamping and machining, it is used to give a matte texture to the surface and enhance light diffusion.

It is used in various fields such as home appliances, building materials, and display components for improving design and functionality.

 Coating Processing

Coating processing is a method of applying functional liquid resins to the film surface and drying and curing them to improve performance and appearance.

It can add various functions such as stain resistance, anti-fogging, anti-static, UV protection, and scratch resistance.

Since it can enhance the performance of a film while maintaining its transparency and flexibility, it is widely used in a variety of applications, including optical films, packaging materials, and displays.

 Vapor Deposition and Sputtering Processing

Vapor deposition and sputtering processing are methods of forming thin metal films on the film surface to enhance functionality and design.

Both are used in various fields such as electronic components, packaging, and building materials.

 Corona Treatment

Corona treatment is a method of applying high voltage to the film surface to generate corona discharge, improving adhesion with ink and adhesives.

It is particularly used for materials with smooth surfaces like polyethylene and polypropylene, which are difficult to adhere to.

It is used as a pretreatment for printing, laminating, and coating to improve processing stability and quality.

 Cutting

Cutting processing is a method of cutting films into specified shapes and sizes, essential for product finishing and parts manufacturing.

Cutting processing involves cutting films in a straight line, often used to arrange them into sheet form.

 Embossing Processing

Embossing processing is a method of creating raised and recessed patterns on the film surface by pressing a mold against the film while applying heat and pressure.

It is used to enhance design and functionality, providing visual luxury as well as practical effects such as fingerprint prevention, anti-slip, and light diffusion.

 Annealing Processing

Annealing processing is a method of reducing thermal shrinkage in films by applying heat at a specific temperature and then slowly cooling them.

This process helps to minimize distortion and warping that occur during film manufacturing and molding, making it particularly important for high-precision applications such as electronic components and optical films.
