[Example] I want to switch the sourcing of parts from overseas to within Japan.

Transactions through trading companies are also possible! We manufacture forged parts domestically, so we are open to consultations.

Are you experiencing issues such as delays in the supply of parts from overseas due to the COVID-19 pandemic and looking for domestic alternatives? Or delays in maritime transport causing parts from abroad not to arrive as scheduled? Our company manufactures forged parts domestically (in Yamanashi Prefecture), so we are available for consultations. We can engage in direct transactions as well as transactions through trading companies. Please feel free to contact us when you need assistance. [Background of the Order / Concerns] ■ Due to the impact of the COVID-19 pandemic, the supply of parts from overseas has been delayed, and we are looking for domestic alternatives. ■ Parts from overseas are not arriving as scheduled due to delays in maritime transport. ■ With the yen depreciating, we would like to switch to procurement from domestic manufacturers. *For more details, please refer to the PDF document or feel free to contact us.

[Exhibition Special Page] Fine Cut Method

[Exhibition Special Page] Fine Cut Method

A cutting method that minimizes deformation (warping and burrs) during cutting and ensures high precision in length!

※Automotive World Nagoya 2025 Exhibition Content Our unique shearing technology allows for continuous and high-precision cutting from irregular coils. The flatness of the cutting surface is excellent, and the occurrence of warping and burrs is extremely low, which means that in some cases, the cut pieces can be used directly as components. 【What Fine Cut Can Achieve】 　◆ Process Simplification: Due to the superior flatness of the cutting surface, post-processing (barreling, machining) can be omitted or made more efficient. 　◆ Continuous Production: High mass production capability through continuous cutting from coils. 　◆ Dimensional Accuracy: 　　　　　　　　- Minimal warping results in high length accuracy. 　　　　　　　　- High length accuracy enables stable unit weights. *Examples of use: Slag, weights, etc. 　◆ Method Switching: Achieves switching to fine cut for sintered parts, pressed parts, and former parts. *Alternative parts for sintering and pressing. 　◆ Environmental Consideration: By achieving omissions and efficiency through process simplification, continuous production, and method switching, we can engage in environmentally conscious manufacturing.

Cold Forging Processing Example 1

Cold Forging Processing Example 1

Pioneer of cold forging

Cold forging refers to the process of shaping coil-shaped materials at room temperature by continuously applying a certain amount of force without heating, using equipment such as a parts former (horizontal multi-stage cold forging machine) and molds. Plastic processing is a method that utilizes the property of metal materials that, when subjected to a certain amount of force through processes like hammering, stretching, or drilling, they deform and do not return to their original shape (plastic deformation).

[Case Study] Custom Screw Manufacturing Process

[Case Study] Custom Screw Manufacturing Process

Our unique production process! We will continue our relentless challenge aimed at creating valuable things.

Here is an example of a proposed flow for the production of custom-made screws. Our unique production process flow (flowchart) is as follows: Basic drawing (meeting) → Selection of manufacturing method → Factory meeting → Creation of manufacturing drawings (customer) → Order receipt → Prototyping → Customer check → Mass production → Surface treatment → Inspection → Packaging → Delivery Additionally, we also propose the "Cock Method (Consignment Sales Method)" to eliminate inventory management and purchasing hassles, as well as our "Assembly Business." At our company, we listen to our customers' requests, consider various manufacturing methods, and propose products that satisfy our customers by solving their fastening-related issues. *For more details, please refer to the PDF materials or feel free to contact us.

What is cold forging? Solving issues such as "the cost reduction of parts is not progressing"!

What is cold forging? Solving issues such as "the cost reduction of parts is not progressing"!

From machining to forging! Achieve significant cost reduction and quality improvement with VA/VE proposals. For custom screws and fastening parts with complex shapes, leave it to Ishiwata Screw Manufacturing.

Are you facing issues like 'the cost reduction of parts is not progressing,' 'we are struggling with insufficient strength,' or 'the machining process takes too long'? While machining allows for high-precision processing, it often results in a lot of material waste (cutting chips) and can be time-consuming, leading to higher costs. Additionally, the cutting of the metal's fiber structure can leave challenges regarding strength. At Ishiwatari Screw Manufacturing, we strongly support our customers' VA/VE proposals, leveraging the cold forging technology we have cultivated over many years. Cold forging has the following advantages as it shapes materials by compressing them in a mold without cutting. We respond to a variety of materials and work 'together with our customers' from the prototype and development stages. Even from a single drawing, we can propose the optimal shape and method. We also offer one-stop solutions for secondary processing (machining, polishing, etc.) after forging. Under a thorough quality assurance system based on ISO9001, we deliver reliable products to our customers. If you are struggling with cost reduction or quality improvement of fastening parts, please feel free to consult Ishiwatari Screw Manufacturing. *For more details, please contact us or download our catalog.
