The measurement principle and advantages of shore hardness testing machines, and the historical background of the development of the spring industry.

The measurement principle and advantages of shore hardness testing machines, and the historical background of the development of the spring industry.

[Reproduction Private Spring Preparatory School Lecture 4] A different measurement method! Explanation of the Shore durometer applying the principle of rebound.

Today, let's study the last remaining Shore hardness testing machine. This hardness testing machine is called a rebound type, and it is completely different from the previous indentation hardness testing machines. The rebound type means that when a golf ball is dropped onto the floor, it bounces back, but the height of the bounce changes depending on the type of floor. For example, if you place a towel on the floor, the bounce height will be different. In other words, when a ball is dropped from a certain height, it will bounce back higher on a hard floor and lower on a soft floor. The Shore testing machine applies this principle. *For more detailed information, please refer to the PDF. If you have any questions, feel free to contact us.*

The relationship and challenges between the development of the Japanese spring industry and the automotive industry.

The relationship and challenges between the development of the Japanese spring industry and the automotive industry.

[Reproduction Private Spring Preparatory School Lecture 12] The hardness of each railway plate spring is measured! Brinell hardness testing machines are installed simultaneously in all factories.

The research institute acquired the Rockwell and Vickers hardness testing machines in Showa year 3 and year 10, respectively. Since they were purchased ten years after the invention of the testing machines, it cannot be said that their acquisition was particularly early. It is likely that both testing machines also made their way into the Japanese spring manufacturing industry around this time. Research on the domestic production of piano wire was promoted around Showa year 13, and machines like Vickers greatly contributed to this research. Currently, the National Railways measures the hardness of each leaf spring individually, but this practice began in Showa year 27, which is why Brinell hardness testing machines were installed simultaneously in all National Railways factories that year. *For detailed content of the article, please refer to the PDF. For more information, feel free to contact us.

Hardness testing contract services | JTL

Hardness testing contract services | JTL

We will conduct various hardness evaluations tailored to the material and structure of the sample.

In this service, we conduct hardness tests (hardness examinations), which are one of the methods for evaluating the "mechanical properties" of material surfaces, on a contract basis. Since the evaluation methods for hardness tests vary depending on the material and structure of the sample, it is important to appropriately select the testing equipment, sample preparation, and measurement conditions. At JTL, we support various hardness evaluations, primarily focusing on Vickers and micro-Vickers hardness as well as durometer hardness, and we provide evaluation data that matches the sample and testing objectives.

Contracted services for tensile testing, compression testing, and bending testing.

Contracted services for tensile testing, compression testing, and bending testing.

We evaluate the strength of various materials and products using a tensile and compression testing machine.

This equipment will evaluate the "strength," one of the "mechanical properties," of materials such as metals, plastics, and ceramics, as well as products and parts like die-cast items and resin-molded products. "Mechanical properties" refer to the inherent characteristics of materials that determine their durability against external forces such as tension, compression, and shear, and are important indicators for assessing the ease of processing materials and the durability of the finished products. We can accommodate tests in accordance with standards, and even for non-standard testing methods or specimen shapes, we can provide flexible support by creating jigs and processing specimens according to the specific requirements.

Weather Resistance Testing Contract Services | JTL

Weather Resistance Testing Contract Services | JTL

We will conduct weather resistance tests and measurements of color difference, glossiness, and haze after the tests.

This service conducts weather resistance tests to evaluate the degradation effects of sunlight (ultraviolet rays) on products and components. Weather resistance refers to the resistance to degradation primarily caused by sunlight, rain, snow, temperature, humidity, and ozone in the natural environment. To assess this, it is necessary to conduct outdoor exposure tests or accelerated weather resistance tests using artificial light sources. JTL's weather resistance testing service can artificially recreate indoor and outdoor sunlight conditions using xenon light sources, accelerating degradation faster than in natural environments. Tests can be conducted on paints (JIS K 5600-7-7), building materials (JIS A 1415), plastics (JIS K 7350-2), coatings, printed materials, textiles, and more, complying with various standards such as JIS, ISO, and JASO.

Supercritical foaming injection molding evaluation test contract service

Supercritical foaming injection molding evaluation test contract service

We accept molding tests using product molds and molding tests with molds owned by our company.

Supercritical fluid (SCF) is a fluid that possesses both gas and liquid properties above its critical temperature and pressure. It has low viscosity and high diffusivity, making it advantageous for mass transfer compared to liquid solvents, and it can achieve significant differences in solubility with only changes in pressure. The technology of supercritical foaming molding utilizing SCF was established in the 1980s by MIT in the United States, and it is currently licensed under the name "MuCell(R)" by Trexel Inc. Our company conducts evaluation tests for supercritical foaming injection molding. Please feel free to consult us if you have any requests. [Test] ■ Molding tests using the client's product mold (on-site observation available) ■ Molding tests using molds owned by DJK (on-site observation available) - Foaming molding using a short shot method with a test piece mold - Full shot molding (shrinkage, warpage, dimensional accuracy, appearance of molded products) - Core-back molding (foaming ratio of approximately 1.5 to 2 times, up to a maximum of 6 times) *For more details, please download the PDF or feel free to contact us.
