We would like to introduce a case study where we produced 20 pieces of insulation and vibration-damping sheets for water level gauges using the heat-resistant "TOMBO No.6750-S (Vermosal Sheet-S)." "TOMBO No.6750-S" is a non-asbestos heat-resistant sheet made primarily from inorganic minerals and formed through a papermaking process. Compared to conventional asbestos sheets, it has a thermal conductivity that is approximately 30% lower, demonstrating excellent heat retention and insulation effects. The size is 34mm × 340mm (equivalent to 9B size). Using our plotter processing machine, we cut the sheets directly from CAD data to precise dimensions without the need for a die. 【Case Overview】 ■ Material: TOMBO No.6750-S 1.5t ■ Size: 34mm × 340mm (equivalent to 9B size) ■ Quantity: 20 pieces *For more details, please download the PDF or feel free to contact us.

We would like to introduce a processing example of producing mats and partitioning materials measuring 440mm × 1800mm from flexible polyvinyl chloride resin (2mm thick) that excels in flexibility and transparency. Flexible transparent PVC is a type of polyvinyl chloride resin that has been made flexible by adding plasticizers, combining high transparency and toughness. It is stable against acids, alkalis, and fats, making it resistant to degradation even in factory environments. The processing details include eight small diameter holes of φ3mm and specified slit processing. Using our plotter processing machine, we achieved high-precision cuts directly from CAD data without moving the material. 【Case Overview】 ■ Material: Flexible transparent PVC 2mm ■ Size: 440mm × 1800mm ■ Processing Details: Eight φ3mm small diameter holes, slit processing *For more details, please download the PDF or feel free to contact us.

This is an example of producing a framed irregularly shaped gasket measuring 210mm x 355mm from the special sheet gasket "Three Sheet 201S" (thickness 0.1mm) manufactured by Three Bond Co., Ltd. The Three Sheet packing is a special gasket that combines the advantages of both solid sheet gaskets and liquid gaskets. It is impregnated with a unique viscous material in long and strong fibrous materials, providing flexibility and excellent conformity to flange surfaces. The processing includes cutting the outer circumference and applying an R65 curve to the inner diameter. Using our plotter processing machine, we precisely cut the material according to the CAD data without damaging it. 【Case Overview】 ■ Material: Three Sheet 201S (0.1t) ■ Size: 210mm x 355mm ■ Processing Details: Outer circumference cut, R65 curve processing on the inner diameter *For more details, please download the PDF or feel free to contact us.

This is a case study of manufacturing block-shaped gaskets measuring 60mm × 95mm from 20mm thick CR rubber (chloroprene rubber). CR rubber is a rubber material that possesses a balanced combination of high weather resistance, heat resistance, oil resistance, and chemical resistance. Compared to other general-purpose rubbers, it has a low flammability characteristic (flame retardant). The processing details include counterboring to sink the heads of bolts and C10 chamfering around the entire product. Using our plotter processing machine (with router function), we minimized the distortion typical of thick rubber and achieved a sharp finish. [Case Overview] ■ Material: CR Rubber 20t ■ Size: 60mm × 95Lmm ■ Processing Details: Counterboring, C10 chamfering around the entire perimeter *For more details, please download the PDF or feel free to contact us.

We would like to introduce a processing case where 22 seals were produced from 3mm thick neoprene sponge (Neo-spot) in the size of 148mm × 478mm. Neoprene sponge is a well-balanced rubber sponge material with excellent weather resistance, heat resistance, flame retardancy, and oil resistance. Its closed-cell structure makes it difficult for air and water to pass through, maintaining high airtightness and water resistance. The processing details include four bolt holes with a diameter of 10mm and R30 curved processing on the inner diameter corners. Using our water jet cutting machine, we precisely cut the soft sponge material with sharp edges according to the CAD data without crushing it. 【Case Overview】 ■ Material: Neoprene Sponge 3t ■ Size: 148mm × 478mm ■ Quantity: 22 pieces *For more details, please download the PDF or feel free to contact us.

In this document, we thoroughly analyze the core "structure" and "features" of D1000, explaining why it can withstand harsh environments, while comparing it with other types of gaskets. We provide detailed explanations using diagrams and images regarding the robust sealing mechanism, its decisive role, and the special configurations of the product. This is a valuable reference, so please take the time to read it. 【Contents】 ■ Areas that exceed the limits of joint sheets ■ Features of the spiral gasket D1000 ■ The core of D1000 - The robust sealing mechanism created by the "spiral" structure ■ The decisive role of the "inner and outer rings" in maximizing performance ■ The diverse product configurations and special adaptations of D1000 ■ For complex insulation design and product selection, consult the experts at "Daiko" *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where we manufactured a gasket for a screw pump gear case using the expansion graphite joint sheet "TOMBO No.1120" with a thickness of 0.5mm, based on the drawings received from the customer. The size is 220mm x 384mm, and the processing details include precisely creating 14 bolt holes with a diameter of 14mm and 2 main port holes with a diameter of 130mm. Using our plotter processing machine, we accurately cut the very thin and delicate material without damaging it, following the CAD data. 【Processing Features】 ■ No die required, can handle from one piece ■ Precise cutting of thin materials ■ Easy repeat orders with data storage *For more details, please download the PDF or feel free to contact us.
