Shall we reduce costs and lighten the load?

Shall we reduce costs and lighten the load?

Implementing integrated production in-house! We manufacture various forged products according to customer needs.

When comparing the material weight and scrap weight of products machined from round bars versus those machined from forged products, there is a significant difference in the amount of processing required, even if the finished products weigh the same. By incorporating the forging process, substantial cost reductions in both material and processing costs can be achieved. Additionally, by utilizing the flow of the internal structure of the metal, forged flow lines that conform to the shape can be obtained, allowing for the production of strong products and enabling weight reduction. 【Features】 ■ Cost reduction ■ Short delivery times ■ Small lot production *For more details, please refer to the PDF document or feel free to contact us.

Would you consider switching to forged products instead of gas cutting for plates thicker than 200 mm?

Would you consider switching to forged products instead of gas cutting for plates thicker than 200 mm?

Are you struggling with rising material costs? By reviewing the processing steps, you might be able to achieve cost reductions.

In recent years, due to the policies of major manufacturers, the availability of steel plates (ultra-thick plates) over 200mm has significantly decreased. At Daimaru Steel Co., Ltd., we can manufacture forged products in block or disc shapes with a plate thickness of 200mm or more to your desired dimensions. Compared to gas cutting, switching to forged products improves yield and contributes to cost reduction, which is why we are currently receiving many requests to transition from thick plate cutting to forging. Given the ongoing rise in material prices, we encourage you to consider procuring forged products when sourcing plate materials. 【Manufacturing Examples】 ■ S25C: Thickness 500mm × Width 750mm × Length 1500mm, Weight: Approximately 5 tons ■ SS Material: Thickness 350mm × Width 1000mm × Length 1200mm, Weight: Approximately 3.2 tons Our company is capable of forging block shapes to your desired dimensions for weights of approximately up to 10 tons. *For more details, please download the PDF or feel free to contact us.

[Case Study] Switching to Forged Products by Adjusting Head Height Accuracy

[Case Study] Switching to Forged Products by Adjusting Head Height Accuracy

Even things that are difficult to realize can achieve precision management by utilizing CAD data!

We would like to introduce a case study of improvements in the machining of mechanical parts proposed by Naox Co., Ltd. When we received the drawing for the upper roller and attempted to process it, we found that there were no detailed specifications on the drawing. The situation required high precision for assembly on the customer’s side, but there was significant variation due to the welded parts. Thanks to our proposal, it became possible to manufacture high-precision products. 【Case Study】 ■ Issues - Request from a mechanical parts machining manufacturer - We received the drawing for the upper roller and attempted to process it, but there were no detailed specifications on the drawing - The situation required high precision for assembly on the customer’s side, but there was significant variation due to the welded parts ■ Naox's Initiatives - Converted the drawing into CAD data and incorporated precision inspection drawings - Through the creation of software to visualize and monitor production changes, we discovered that forged parts could be processed with higher precision than welded parts - Proposed to the client to switch to forged parts to achieve the required precision *For more details, please refer to the PDF document or feel free to contact us.

Shortening of Joining Processes: Types and Applications of Forging

Shortening of Joining Processes: Types and Applications of Forging

By crushing, it can be processed into various shapes! A technique that induces work hardening in metal materials to increase strength.

Forging is a type of metal processing that involves shaping metal materials by hammering or pressing them into various forms. It is classified into three types based on the temperature during the forming process: cold (room temperature), warm (600–900°C), and hot (900–1250°C). Our company employs "cold forging" using a press machine. By using cold forging technology to create "integral shapes" from parts that have been joined through welding, crimping, or fitting, we can enhance the strength and reliability of the components. 【Types of Forging (Partial)】 ■ Cold Forging - Processing temperature is at room temperature (20–30°C) - Capable of forming with higher precision in dimensions and surface accuracy than warm or hot forging - Reduces the need for cutting processes - Aims for cost reduction of products *For more details, please refer to the PDF document or feel free to contact us.
