A stainless steel foundation packing for wooden buildings in Japan, which has a wide ventilation area and high strength, suitable for the humid and earthquake-prone environment.
"Nekonika" is a stainless steel foundation packing that is resistant to moisture and earthquakes. With a thickness of 9mm, it strongly supports the seismic strength of anchor bolts. Due to the narrow gap between the foundation and the base, it shows significant resistance to lateral shaking and bending pressure during earthquakes. The open space between the foundation packings promotes the drying of wood. Increased ventilation prevents decay and keeps termites away. 【Features】 ■ Foundation packing resistant to moisture and earthquakes ■ Proven to have greater strength than a 20mm gap ■ Made of stainless steel at a low cost ■ No need for rodent-proofing materials due to the 9mm thickness ■ Reduces factors that cause the base to rot, creating an environment less conducive to termite habitation *For more details, please refer to the related links or feel free to contact us.

Leave graphite molding to Digic!
It is expandable graphite that is self-lubricating, size-stable, and has barrier properties against gases and fluids.
We offer two types: endless type and bias cut type.
The valve pump packing "grand packing" is prone to vertical deformation in response to tightening force from above, and its axial surface (inner and outer diameter) serves as the sealing surface, demonstrating sealing performance against fluids. Additionally, by combining it with braided packing, the sealing capability is further enhanced, with the braided packing acting as a backup ring. The manufacturing process involves wrapping a tape-like thin sheet around a dedicated molding die in a concentric manner and performing several compressive moldings using a hydraulic press. The molded sizes can accommodate a wide range of external diameters from φ9 to φ600, and there are mainly two types of molded products available: the endless type and the bias cut type with a 45-degree cut. For more details, please download the catalog.
It completely prevents graphite from leaking through gaps during compression.
The "Inconel Packing," a leakage prevention type packing for valve pumps, completely prevents graphite from leaking through gaps during compression by integrally molding an Inconel braided packing into the corner sections of the graphite packing. It is suitable for environments with large inner and outer diameter clearances, and can be used in a clearance range of approximately 0.3mm to 0.7mm. We also offer reinforced corner types (square) and bottom taper types (30-degree taper) to meet customer needs. Like the mesh type, it excels in compressibility and elasticity, making it suitable for harsh temperature environments ranging from extremely low to ultra-high temperatures. Additionally, it has minimal stress relaxation, providing excellent sealing performance over long periods. For more details, please download the catalog.
Excellent chemical resistance! O-ring type sealing ring with excellent heat and cold resistance.

O-seals are made by bonding and fusing materials, allowing for the production of large diameter seals, such as those with a diameter of 5m. The manufacturer, Chrysler Encapsulated Seals in the United States, has a proven track record with these seals, and their performance and quality are well-regarded. 【Features】 ■ Excellent chemical and solvent resistance, preventing contamination of fluids (products) ■ Excellent heat and cold resistance (FEP: -250℃ to +260℃, PFA: -250℃ to +260℃) ■ Compatible with conventional O-ring sizes, allowing for easy modifications For more details, please contact us or download the catalog. *This catalog is in English.
Durable and long-lasting due to the use of Kevlar! It performs well in harsh environments such as steel, ships, high-pressure presses, and extruders.
The "CARCO Seal" is a product from CARCO, which provides high-quality radial shaft seals (oil seals) and V-packings used in harsh environments. It is widely adopted in various fields, both domestically and internationally, including steelmaking, shipping, high-pressure presses, and extruders. The use of "Kevlar" in the reinforced fabric of the sealing ring makes it resistant to damage and ensures a long lifespan. Additionally, it is delivered in pre-adjusted dimensions, eliminating the need for length adjustment (trimming) during seal installation! This allows for smooth delivery operations without relying on the skill level of trimming. We offer a lineup that caters to various applications. Please feel free to consult with us. 【Features】 - Long lifespan (high durability) - No trimming (excess length management) required during installation - Teflon coating prevents stick-slip - Short delivery time (1.5 months or less) - Facilitates seal assembly and reduces replacement time *For more details, please refer to the PDF or feel free to contact us. *The downloadable PDF is in English.

![[Useful Information] Deburring of Surface Treatment Steel Plates](https://image.mono.ipros.com/public/product/image/b4d/2000292398/IPROS753845972747402184.png?w=280&h=280)
Introducing the surface treatment quality inspection results of plated steel sheets before and after deburring.
Authentec Co., Ltd. is a company that sells and provides maintenance, regeneration, and services for sheet metal and finishing equipment. One of the primary concerns for those in the sheet metal industry is that deburring surface-treated steel sheets will cause the surface treatment to peel off. In reality, there is no need for such concern. This document presents the reasons along with actual survey results. [Contents] ■ Deburring of surface-treated steel sheets ■ Quality survey results of surface treatment on galvanized steel sheets before and after deburring ■ Cross-sectional SEM observation ■ Additional experiment "Salt spray test" *For more details, please refer to the catalog or feel free to contact us.

To alleviate the customer's concerns, we conducted sample experiments and salt spray tests!
For those in the sheet metal industry considering deburring of sheet metal products, the primary concern is likely that deburring surface-treated steel plates will cause the surface treatment to peel off, isn't it? In response, Authentec conducted sample experiments. The results proved that the physical condition of the surface-treated steel plates after deburring is almost equivalent to their condition before deburring. However, to address the concerns that one cannot feel assured until it is confirmed that "rust does not occur," we also conducted a salt spray test on the same product. These experiments demonstrated that our deburring machine "AuDeBu" can perform deburring without affecting the coating of surface-treated steel plates. *For more details, please refer to the PDF document or feel free to contact us.*
