This catalog is a must-see for anyone involved in metal processing! It contains fundamental yet important information!

We will make proposals based on our predictions of potential issues as much as possible, in order to ensure a stable supply of parts that meet the truly necessary functions and precision at reasonable mold and product prices. Additionally, we will submit a quote after gathering necessary information, such as the total expected production quantity (guaranteed shots for the mold).

We solve your problems with precision sheet metal parts using our pressing technology! We are currently offering materials that include key points on mold production!

For more details, please refer to the PDF document or feel free to contact us.

Explaining the key points in selecting materials for springs. Please feel free to consult us about design concerns or prototypes!

**About Prototype Leaf Springs** Our company specializes in thin plate spring products, which are difficult to assess in terms of spring properties, sliding properties, and durability. For the production of blank shapes (cut shapes) during prototyping, we select processing methods considering accuracy and quantity, including fine laser processing (beam diameter 0.03), wire electrical discharge machining, etching, and press processing using simple molds. For bending processing, we utilize a wealth of available temporary molds as much as possible to achieve short delivery times and low costs. We offer a rapid response with a prototype estimate in 3 hours, expedited prototyping in as little as 3 days, and subsequent mold production in as little as 2 weeks. We also accept prototyping orders alone. **Exhibition Information** ◎ Medtec Japan ■ Date: April 9 (Wed) - 11 (Fri), 2025, 10:00 - 17:00 ■ Location: Tokyo Big Sight ■ Booth Number: 805 ◎ Intermold / Mold Exhibition / Metal Press Processing Technology Exhibition <Tokyo> ■ Date: April 16 (Wed) - 18 (Fri), 2025, 10:00 - 17:00 ■ Location: Tokyo Big Sight, East Hall 4 ■ Booth Number: 141-62 *For more details, please feel free to contact us.*

This is a must-see for those who want to achieve weight reduction! Magnesium alloy is the lightest material among practical metals while also being high-strength.

Please propose a design. We will design and manufacture molds for magnesium press processing and create press-processed products.

Please propose a processed design. We will handle mold design and manufacturing, as well as the production of pressed products.

Please realize ultra-lightweight and high-rigidity metal products made from magnesium alloy thin sheet pressings.

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.
