Special cold forged parts

Contributing to cost reduction and solving assembly challenges! Supporting various processes such as polishing and knurling!

"Special cold-formed parts" are components processed by applying pressure to metal at room temperature, resulting in deformation and shaping. It is possible to manufacture stepped, large-headed, middle-necked, eccentric, and irregularly shaped shaft parts, among others. By using molds made of materials such as carbide for the forming process, products with uniform precision can be mass-produced. Additionally, because the fiber flow is continuous, high strength can be achieved. [Features] - Increased strength and uniform dimensional accuracy - Contribution to sustainability through resource conservation - Enhanced functionality of parts and overall cost reduction in assembly - Provision of suitable functions for fastening conditions, including anti-loosening and contamination measures *For more details, please refer to the PDF document or feel free to contact us.

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

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"!

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.

Leave the "cold forging processing" in Osaka Prefecture to us!

Adopted in various fields such as construction, automobiles, home appliances, tools, industrial machinery, and steel furniture! Capable of mass production as well as small lot items!

The technology of shaping metals by applying pressure in a room temperature environment is called cold forging. By cutting wire inside the machine and applying pressure to the metal using molds, it is deformed while being drawn or expanded, automatically processing it into the desired shape. Since there is no cutting process, there are no chips produced, and material loss is extremely minimal. Because it is processed with molds, the processing accuracy is high, and there is little variation in quality. Kagoshima Metal has a wealth of production equipment, including large machines with a pressing capacity of 400 tons, and achieves high-efficiency production by using the optimal machine suited to the shape and size of the manufactured products. 【Applicable Materials】 Carbon Steel Alloy Steel Boron Steel Stainless Steel Aluminum Copper *For more details, please refer to the PDF document or feel free to contact us.
