A shim plate is a type of plate used in work sites such as machine manufacturing to easily fill gaps and adjust heights. Even when made by machines, achieving uniform dimensions is nearly impossible due to the accumulation of material and manufacturing tolerances. In such cases, using shim plates of various thicknesses and shapes can help achieve dimensional uniformity. Our company offers a wide selection from a rich inventory of plate thicknesses, and we can accommodate thickness tolerances down to the micron level. If you are having trouble with height adjustments or gap filling in complex shapes, please feel free to contact us. We will provide solutions with unique proposals from SGK Etching. In our PDF materials, we explain shim plates using industry-unique features, photos, and diagrams. *For more details, please refer to the PDF materials or feel free to contact us.

Photo etching is a chemical precision processing technology that uses a photographic plating process on materials such as metals to form a corrosion-resistant film in the required pattern and partially etch the material. 【Do you have any of these concerns?】 - I want to confirm the shape with a prototype, but I can't afford the cost of a mold. - I need precision spacers of various thicknesses without burrs or warping. - I want to create products with uneven surfaces or complex shapes. 【Features】 ■ No burrs By applying chemical processing to create shapes, the cross-section remains stable. Unlike physical processing, burrs do not occur. ■ No distortion Etching can be performed without adding extra stress to the material. It is advantageous for processing products that require strict flatness and dislike deformation. ■ Expertise in thin materials Delicate products with a material thickness of 50μ or less can be processed precisely. ■ Expertise in micro-processing Extremely small parts that are impossible to process with other metalworking methods can be manufactured. ■ Expertise in creating narrow pitch products It is possible to arrange shapes in a narrow pitch that cannot be reproduced with molds. *For more details, please refer to the PDF document or feel free to contact us.

Photo etching processing is a machining technology characterized by the absence of burrs and distortion, utilizing chemical treatment to create shapes, resulting in stable cross-sectional shapes. It allows for processing without adding extra stress to the physically machined materials, making it advantageous for products that require strict flatness and those that are sensitive to deformation. Additionally, we have a proven track record in mass production and are confident in our capacity. We also have experience and achievements in composite processing, utilizing various know-how to challenge product creation. 【Features】 ■ No burrs ■ No distortion ■ Expertise in thin materials ■ Expertise in micro-processing ■ Expertise in producing products with narrow pitches *For more details, please refer to our catalog or feel free to contact us.

At SGK Co., Ltd. Tokyo Sales Office, we actively engage not only in standard etching products (functional parts, fine parts, flat plates, and standard materials) but also in exterior parts, large parts, three-dimensional etching, and special material etching. While general etching manufacturers primarily work with iron-based and steel-based materials, including stainless steel, our office is capable of processing materials such as titanium, molybdenum, tungsten, Inconel, as well as magnesium, clad materials, and even nickel-titanium and cobalt-chromium. We generally consider all materials except platinum to be etchable, but for new materials, we will process them after conducting test confirmations. Additionally, in three-dimensional etching, while general etching manufacturers mainly focus on flat plate processing, we are capable of etching not only flat plates but also shafts, pipes, and spheres.

The low-reflective black treatment "IS-B" is a technology that colors the metal itself black, significantly reducing light reflectance, unlike matte finishes achieved through painting or coatings. By using it in optical devices such as cameras, it prevents the occurrence of ghosting and flare. It maintains high dimensional accuracy without changes in film thickness, and by using stainless steel as the base material, it also provides strength, durability, and heat resistance. 【Features】 ■ Reduces reflectance to about 1% in both the visible light and infrared regions ■ Excellent compatibility with etching processes ■ Compatible with sensor components *For more details, please refer to the materials. Feel free to contact us with any inquiries.
