協和合金 List of Products and Services

This product is an assembly kit for the SE-905 Stirling engine, with parts that require special tools already assembled. It is designed so that anyone can assemble it with commercially available screwdrivers and hex wrenches. If it does not operate, we will make adjustments. Except for defective parts, this service will incur a fee. 【Specifications】 ■ Recommended age: 15 years and older ■ Material: Aluminum die-cast ■ Country of manufacture: Japan ■ Color: Black ■ Uses aluminum die-cast piston cylinder and 8 miniature bearings ■ The product has been checked for operation before shipment and comes with a fully assembled generator. *For more details, please refer to the PDF document or feel free to contact us.

At Kyowa Alloys, we manufacture simple molds through our unique design process (3CD process). This process enables a seamless system from design to mold production and die casting in-house, combined with special mold materials and casting methods, allowing for short delivery times and small lot die casting of several dozen to several hundred pieces, which was previously difficult. By applying this technology, we assist customers in product development and die-cast product design. Please utilize this as a product development method that allows for low-cost and short delivery times for small lot products. 【Features】 ■ Our unique design process ■ Supports small lots and high functionality ■ Enables short delivery times and small lot die casting of several dozen to several hundred pieces, which was previously difficult *For more details, please refer to the PDF materials or feel free to contact us.

• Mold Design

Shapes that are disadvantageous for cutting processes, such as thin materials and convex shapes, present challenges such as "the need for innovative jigs to process the outer peripheral shape" and "a large amount of material removal from the product." On the other hand, shapes that are advantageous for mold processing, such as thin materials and convex shapes, offer various benefits, including fewer constraints on cutting parts and outer peripheral shapes for removal processing of product sections and gates. **Benefits of shapes that are advantageous for mold processing:** - Fewer cutting parts for removal processing of product sections and gates - Ability to digitize gate proposals along with product data, allowing simultaneous processing with product sections - Fewer constraints on outer peripheral shapes (basically, steps are a load) - No need for special jigs during processing (easy clamping of the workpiece) *For more details, please refer to the related link page or feel free to contact us.*

This is an introduction to mold manufacturing examples using 3D CAD. At the product design stage, we create data considering factors such as draft angles, uniform wall thickness, parting lines, and corner radii. 【Creation Process】 ■ Day 1: Develop the mold ■ Day 2 - For multiple parts, create the product section directly on the mold - Create runners, gates, and air vents ■ Day 3: Create CAM data ■ Days 4-5: Precision NC machining / Single setup ■ Day 6: Polishing adjustments ■ Day 7: Die casting / Completion *For more details, please refer to the related link page or feel free to contact us.

We would like to introduce various customer feedback regarding the introduction of simple molds. "Since we were producing niche market products in small lots using lost wax until now, thanks to the '3CD process,' we were able to achieve quality and pricing that can compete with large companies." (Mr. M, President of Company K, lighting components) "We were grateful that they worked with us in 3D from the design stage. We were able to create a product that doesn't seem like it came from a one-person company, and we proudly made a fresh start." (Mr. K, President of Company T, mechanical components) We have received opinions like these. *For more details, please refer to the related link page or feel free to contact us.*

• Mold Design

The "SE-905HP" is a Stirling engine designed with a structure that incorporates the functions of a regenerator while avoiding the insertion of a matrix, which traditionally increases pressure loss and negates effectiveness in small engines. It achieves a thermal efficiency of over approximately 50% compared to conventional designs, resulting in a significant increase in output. 【Features】 ■ Regenerator function without the insertion of a matrix ■ Heat exchange rate of over approximately 50% compared to conventional designs ■ Significant increase in output *For more details, please download the PDF or feel free to contact us.
