Transporting a wheelchair in a welfare vehicle is always fraught with danger. Elderly individuals with weak core strength may slip out of their wheelchairs during transport, and only a single seatbelt can be fastened around their abdomen. If sudden braking or an accident were to occur in such a situation... Are you aware that fatalities have occurred during wheelchair transport due to seatbelt constriction? Hashimoto Engineering has developed an original product, the "Seatbelt Protector," to address this issue. *You can view the detailed content of the blog through the related links.

At Hashimoto Engineering, every Monday morning, all employees at the headquarters gather for a morning assembly. During the assembly, there is a speech from the president, and recently there was a discussion about the future of automobiles, including EVs, hydrogen, and internal combustion engines. Upon reflection, I realized that I don't know much about the various power sources other than gasoline engines and their respective characteristics. Therefore, this time, I decided to research automobile power sources as a way to study for myself. *For more details, you can view the blog through the related links.

This time, I will introduce intellectual property rights again. I will discuss applications and patent attorneys, as well as cross-licensing agreements. When we request a patent from the Patent Office, what we often hear is "patent application." In fact, the term "patent application" is not a legal term; "patent application" is used as the legal term. In other words, intellectual property experts and patent attorneys only use "patent application." *You can view the detailed content of the blog through the related links.

When you hear about a factory for car and motorcycle parts, what comes to mind? You might picture parts being placed on a conveyor belt, with robots diligently working away. Or perhaps you envision large machines lined up neatly in a spacious factory, all engaged in production. However, our company is not a mass production factory. But we do manufacture parts for cars and motorcycles. *For more details, please refer to the related links. For further information, please check the PDF materials or feel free to contact us.*

Castings" refer to a metal processing method where melted metal is poured into a mold to form shapes, and it is a forming method used in various metal products around the world. In particular, many parts in cars and motorcycles are made through casting. Our company mainly conducts inspections and evaluations of aluminum castings, and we have a deep connection to the casting industry. Therefore, this time we will discuss casting and inspection operations. *For more detailed content of the blog, you can view it through the related links.

This time, I will talk about lightweight technology and its examples. Many of you may be wondering what the "multi-material technique" mentioned in the title is. The multi-material technique involves skillfully using lightweight and strong materials such as "magnesium, titanium, and carbon (CFRTP)" in appropriate places to significantly reduce the weight of metal components. Instead of using lightweight materials with low strength, we use materials that are both lightweight and strong. *You can view the detailed content of the blog through the related links.

Gas analysis supports the improvement of the quality of cast products. Do you have any issues with the quality of aluminum cast products, such as: - Casting defects on machined surfaces - Blistering after painting - Pinholes in plating - Flow marks - Poor flow distribution Measuring gas volume and analyzing components can help identify the following causes: - Inappropriate casting plan - Inappropriate casting conditions - Excess plunger oil - Excess release agent ≪What is gas analysis?≫ Gas analysis is a device that measures the amount of gas contained in aluminum die-cast products in their actual form. Gases generated from the material of the product and surrounding materials can potentially cause troubles. It allows for the identification and clarification of the causes of issues, contributing to quality control. By connecting gas analysis equipment with a gas chromatograph, analysis of the gas components contained in the product can also be performed. Our company offers contracted gas volume measurement and component analysis services. We also accept requests from distant locations. We will create reports and discussions on gas volume measurement and component analysis tailored to your needs. The insights created by personnel with over 20 years of experience in major casting manufacturers will surely be beneficial to our customers.

"Lightweight, no maintenance, long lifespan!" One of the major challenges in aluminum casting is the short lifespan of casting tools due to melting. Therefore, our company has developed the titanium melting tools "DTi" series, which excel in corrosion resistance against aluminum molten metal, achieving long lifespan and lightweight design. 【Effects】 ■ Dramatic improvement in service life While iron slag skimmers require maintenance once a week and melt within three months, DTi can be used for over a year without maintenance and without melting. ■ Excellent oxidation film and slag detachment Oxidation films and slag easily fall off with a light tap. ■ Lightweight due to titanium! It also reduces work burden and contributes to work style reform. ■ Reduction in casting defect rates due to stabilization of pouring volume. 【Product Lineup】 ■ DTi Slag Remover Available in standard sizes from φ130 to φ245. Custom shapes and sizes can be accommodated. ■ DTi Ladle (for pouring) Proven for 5kg use. Sizes from 1kg and up can be produced. ■ DTi Surface Detection Pin Reduced frequency of replacement. Available in φ15 and custom sizes. ■ DTi Ladle Currently under development. Please wait a little longer. We have received numerous inquiries.
