Filter PRO1D C-PL SUPER SLIM

Filter PRO1D C-PL SUPER SLIM

Basic filters useful for creating works in both digital and film.

PL filters are used by many customers as filters that help remove reflections and enhance contrast in color photographs. Traditionally, PL filters have been considered thick due to their rotating structure and the fact that the "polarizing film," which is the heart of the PL filter, is sandwiched between two pieces of glass, resulting in a filter that can cause vignetting (darkening around the edges) when used with wide-angle lenses. However, in recent years, responding to the demand for PL filters that can be used with wide-angle lenses, Kenko has released a thin "wide-angle compatible PL filter" by polishing the glass after laminating the polarizing film and reducing the glass thickness to 2mm.

Etching process

Etching process

A technique born from the application of precision photography and photo corrosion methods! An ideal processing method for ultra-small, ultra-thin, and complex-shaped products.

"Etching processing" involves applying corrosion protection treatment through masking, followed by the removal of unnecessary parts using a corrosive solution. This processing method is suitable for ultra-precision requirements that cannot be achieved with press punching, allowing for the production of extremely small, thin, and complex-shaped products. Additionally, "photo etching processing" is a precision processing technology that combines etching processing techniques with precise photographic and imaging technologies. Through the application of precision photography and corrosion processing, it demonstrates high processing accuracy for extremely small parts, ultra-thin products, and complex components in electronics products. [Processing Steps (Excerpt)] ■ Pattern Drawing ■ Pre-treatment (Surface Smoothing, Degreasing) ■ Resist ■ Exposure *For more details, please refer to the PDF document or feel free to contact us.

[Processing Example] Etching Process for Power Devices

[Processing Example] Etching Process for Power Devices

In addition to printed resist, we are implementing innovations using the photo-etching process!

We are performing etching processing on materials that consist of 1.0mm thick copper (Cu) bonded with glass epoxy resin from one side. Hirai Precision Industry has a track record of processing up to 2.0mm thick copper. While copper (Cu) is the mainstream material, aluminum (AL) is also possible. For the insulating layer, we have experience with materials other than glass epoxy resin, including ceramics (aluminum nitride substrates, silicon nitride substrates, etc.), polyimide, and PET film. We often receive materials supplied by customers for etching processing. 【About Etching Processing】 - In addition to printed resist, we employ a photo-etching process for improvements. - This allows for finer finishes and enhanced linearity. - The dimensions of the tapered section of the cross-section can be kept to less than half the thickness of the plate. *For more details, please refer to the PDF document or feel free to contact us.

[Processing Example] Etching Processing - Thickness Adjustment of Material - Reducing Plate Thickness

[Processing Example] Etching Processing - Thickness Adjustment of Material - Reducing Plate Thickness

Short delivery response! By applying etching solution to the entire surface of the metal plate and causing corrosion, the thickness of the metal can be adjusted.

A rich lineup of metal materials (including variations in thickness) is one of the advantages of Hirai Precision Industry. We have established a system to meet various needs, and by utilizing our etching processing technology, we can customize the thickness of the base material freely. Thickness adjustment through etching processing can be done at a lower cost compared to creating the base material from scratch. **Advantages of thickness adjustment processing with etching solution:** - **Cost-effective production:** It is possible to respond at a lower cost compared to creating the base material from scratch. - **Short delivery times:** The delivery time for thickness adjustment processing can typically be accommodated with an additional few days on top of the usual etching processing lead time. - **Small lot production:** There is no need to specify a minimum production quantity; we can accommodate orders starting from just one piece. *For more details, please refer to the PDF materials or feel free to contact us.*

[Processing Example] Etching Processing Cross-Section Shape Taper Shape

[Processing Example] Etching Processing Cross-Section Shape Taper Shape

Utilizing the unique "taper" of etching processing! We can assist you from the prototype stage.

Hirai Precision Industry is a metal processing manufacturer specializing in etching processing. Etching processing uses chemical solutions to dissolve metal and create the necessary shapes. When metal is dissolved during this etching process, a protrusion can form at the center of the cross-section. This is referred to as a "taper." Utilizing this unique "taper" from the etching process, our company assists in various items across different industries. [Types] ■ Front and back difference taper ■ Step taper ■ Indentation taper ■ Protrusion taper *For more details, please refer to the PDF materials or feel free to contact us.

[Processing Example] Etching Process - Metal Foreign Matter (Contamination)

[Processing Example] Etching Process - Metal Foreign Matter (Contamination)

With fine etching processing, it is possible to reproduce metal foreign substances (contaminants) in arbitrary shapes!

Hirai Precision Industries' etching process uses a film or glass plate known as a master plate for processing. Therefore, even if the requested size of the design drawn on the plate is a small shape, it is possible to carry out the processing. Taking advantage of that feature, there are also requests to intentionally create metal foreign objects (contaminants). This serves the purpose of evaluating the removal of foreign objects that may occur during manufacturing. [Case Overview] ■ Product Shape: Individual numbers from 0 to 9 ■ Material: SUS304-CSP-H ■ Plate Thickness: 0.01t ■ Minimum Residual Width: 0.05mm ■ Minimum Cutting Width: 0.05mm ■ Comparison Object: 0.5mm wide mechanical pencil lead *For more details, please refer to the PDF document or feel free to contact us.

[Processing Examples] Etching Processing: Advantages and How to Choose

[Processing Examples] Etching Processing: Advantages and How to Choose

We can also accommodate small quantities! We can deliver without any deformation or distortion!

I would like to introduce the benefits that customers feel regarding the etching processing by Hirai Precision Industry, which leads them to place orders. We can process metal sheets with a thickness ranging from 0.005mm for thin sheets to about 2mm for thicker sheets. Since it is a chemical processing technology that does not apply heat or force, we can deliver products without deformation or distortion, and there will be no burrs in the thickness direction. Furthermore, the more complex the shape, the more we can provide advantages in delivery time and cost compared to other metal processing methods. 【In the following situations】 ■ When the thickness of the metal sheet to be processed is thin ■ When you want to avoid burrs in the thickness direction (Z direction) ■ When you want to manufacture complex and fine shapes ■ When you want to mass-produce fine parts ■ When you want to procure prototypes quickly and cheaply *For more details, please refer to the PDF document or feel free to contact us.
