We will thoroughly explain points regarding the use of stainless steel as a material for springs and joining technologies! *Free materials are currently being offered.

This document contains know-how for manufacturing products using stainless steel as a spring material. It provides detailed explanations on points regarding the use of stainless steel as spring material, such as "selecting materials based on strength levels" and "determining the feasibility of processing by checking the bending characteristics of the material at the finishing level." Additionally, it introduces joining techniques such as "physical joining" and "welding." We encourage you to read it. [Contents] ■ The basics of stainless steel involve adding chromium to provide corrosion resistance. ■ Material selection is based on strength levels. ■ The feasibility of processing is determined by checking the bending characteristics of the material at the finishing level. ■ Other related technologies. *For more details, please refer to the PDF document or feel free to contact us.

[Notice] We have made an investment in the latest Aizawa-manufactured press brake!

  • Company news

In manufacturing, we don't immediately create molds for mass production; instead, we first produce a few prototypes, typically around 100. What we need for this is the press brake. It is a sheet metal machine used to bend thin sheet metal materials. The features of this machine include high repeatability precision, fine adjustment mechanisms that can be tailored to the product, easy clamp for one-touch mold attachment, quick change, CAD/CAM integration, and the capability for internet connectivity for IoT use! Trust Kyo-Wa Hearts not only for mass-produced items but also for prototypes!

Notice of the exhibition "Intermold / Mold Exhibition / Metal Press Processing Technology Exhibition"

  • Seminar・Event

We are pleased to announce that we will be exhibiting at the "Intermold / Mold Exhibition / Metal Press Processing Technology Exhibition," which will be held online from October 5 (Monday) to October 16 (Friday). In light of this, we would like to provide our valued customers with an early announcement↓ We plan to offer technical materials that were originally intended for distribution via a paid newsletter for free this time! Previously, our technical staff and public relations team created these materials, but moving forward, they will be polished by staff who excel in editing, resulting in significantly improved quality! We sincerely apologize for the inconvenience during your busy schedule, but we would greatly appreciate it if you could access the online exhibition. We are truly looking forward to meeting all of you online. If you have any questions or concerns, please feel free to contact us. Please also feel free to reach out regarding consultations on prototypes, material selection, mass production processing, mold repairs, jig manufacturing, factory tours, and more. We also accept wire electrical discharge machining, polishing processing, machining, and press processing of customer-supplied molds. We look forward to hearing from you.

Introduction Materials [Solve Your Metal Processing Problems in One Shot!] Notice of the Flow from Application to Mold Production and Mass Production

  • Catalog news

"What are the functions of the parts required by the customer?" "Where is precision truly needed?" We will ask the customer's design representatives these questions, and our sales representatives will propose and consult on the machining characteristics and limits of the materials to be processed. We will make suggestions based on our predictions of potential issues, ensuring that we can provide parts that meet the necessary functions and precision at reasonable mold and product prices. Additionally, we will gather information necessary for the estimate, such as the total expected production quantity (guaranteed shots for the mold), before submitting the estimate.

Our company specializes in fine, complex, and precision press processing. *We also sell molds! We can handle everything from examining the shape of customer parts, prototyping, mold manufacturing, to mass production processing. 【Our Expertise Developed Over Time】 1. Deep drawing and flat spring processing 2. Fine processing (plate thickness: 0.03) 3. Complex shapes and high-precision bending processing 4. Processing of difficult materials (titanium, shape memory alloys, magnesium alloys, etc.) 【Proposal Power Supporting Quick Start-Up】 Many customers consult us during product development, asking if certain processing is possible, seeking advice during the conceptual stage, or wanting to start with prototyping. In the development phase, we provide comprehensive advice on material and shape decisions, as well as secondary processing, to fully support the launch of new products. We also believe that "refined products are a testament to stable quality," and we enter mass production only after sufficient adjustments (taking extra care). 【Efforts in In-House Product Development】 We are also engaged in in-house product development utilizing our cultivated precision press processing technology. We have developed a new type of file for binding documents, called "Nuke," which allows for easy insertion and removal of documents from the center, attracting attention as an item that enhances office productivity.
