At Tokai Shinken, we specialize in precision stainless steel sheet metal processing. In addition to processing, we can consistently provide surface treatment of stainless steel as required for various applications. Regarding surface treatment, we utilize an external network that can handle processing, allowing us to select the optimal suppliers based on the required treatments such as polishing, chemical treatment, heat treatment, embossing, etching, plating, and painting, while ensuring quality control. We also propose VA (Value Analysis) and VE (Value Engineering) suggestions that take into account design and cost considerations during surface treatment, guaranteeing the provision of high-quality stainless steel sheet metal products at appropriate costs. If you have any products that are causing you trouble regarding stainless steel sheet metal, please contact us. **Features** - A consistent production system utilizing a network of suppliers for various stainless steel surface treatments. - Proposal capabilities for VA and VE based on our track record in stainless steel sheet metal and surface treatment products. - Support for prototypes before mass production, with the ability to propose shape changes and methods with an eye toward mass production! *For more details, please refer to the PDF materials or feel free to contact us.*

Tokai Shinken Co., Ltd. specializes in precision sheet metal and related assembly. When performing bending processing on precision sheet metal products with a short lead time, by considering the material and thickness and conducting the bending based on the limit dimensions, we can prevent warping. In particular, when performing short lead times for thin sheet metal products among precision sheet metal products, by considering the limit dimensions for bending from the design stage, we can prevent rework and the occurrence of defective products, whether they are prototypes or mass-produced items. 【Features】 ■ By considering the material and thickness and conducting bending based on the limit dimensions, we can prevent warping. ■ By considering the limit dimensions for bending from the design stage, we can prevent rework and the occurrence of defective products. *For more details, please refer to the PDF document or feel free to contact us.

Tokai Shinken Co., Ltd. specializes in precision sheet metal and related assembly. When performing blank processing with laser cutting, using assist gas of high-purity nitrogen makes it difficult for an oxide film to form on the cut surface. Additionally, even when welding is done on the cut surface, the finish remains clean, allowing for high-quality appearance in precision sheet metal products that undergo painting or silk screening after welding assembly. [Features] - Using assist gas of high-purity nitrogen in the laser cutting machine makes it difficult for an oxide film to form on the cut surface. - The finish remains clean even after welding on the cut surface. *For more details, please refer to the PDF materials or feel free to contact us.

Tokai Shinken Co., Ltd. specializes in precision sheet metal and related assembly. When welding small sheet metal parts with thin plates using spot welding, securing a space of about 15mm as a spot allowance can prevent quality degradation due to welding heat and pressure. By designing with consideration for deformation and misalignment caused by welding heat and pressure, it is possible to produce high-quality precision sheet metal products without adding unnecessary processes. [Features] ■ By securing a space of about 15mm as a spot allowance, quality degradation due to welding heat and pressure can be prevented. *For more details, please refer to the PDF document or feel free to contact us.

Tokai Shinken Co., Ltd. engages in precision sheet metal processing and related assembly. By performing bending processing at a slightly acute angle from the start, rather than at 90 degrees, we can prevent interference with covers for various industrial equipment and devices without the need for welding to secure them. In particular, for medical devices and equipment where aesthetic qualities such as design and decoration are required, eliminating the welding process can reduce the costs associated with removing welding marks. [Features] - By performing bending processing at a slightly acute angle from the start, we can prevent interference with covers without the need for welding to secure them. - It is possible to reduce costs associated with the removal of welding marks. *For more details, please refer to the PDF document or feel free to contact us.

Tokai Shinken Co., Ltd. is engaged in precision sheet metal and related assembly work. By changing the method of forming the step at the mounting part of the equipment cover door from deep drawing through press processing to spot welding of precision sheet metal parts, we can reduce processing costs. With spot welding of precision sheet metal parts, not only are mold costs eliminated, but the time required for mold arrangement is also no longer necessary. [Features] - No mold costs required - No time needed for mold arrangement *For more details, please refer to the PDF document or feel free to contact us.
