Poisson's ratio measurement

Introducing a case study of measuring Poisson's ratio using a tensile testing machine and strain gauges!

We would like to introduce the Poisson's ratio measurement conducted by our company. Poisson's ratio is the ratio of longitudinal strain to lateral strain that occurs when a load is applied to an object, and it is necessary for strength calculations of materials. We can accommodate Poisson's ratio measurements and strength measurements through tensile testing. Please feel free to consult with us. 【Measurement Examples】 ■ Measurements using a tensile testing machine ■ Strain measurement results and Poisson's ratio calculation results *For more details, please refer to the PDF materials or feel free to contact us.

Clear presentation of analysis results using polyamide imide materials and IR devices, along with data analysis!

This document presents a case study that elucidates the causes of discoloration in super engineering plastic polyamide-imide (PAI) films used in coatings, composite film materials, and various molded products through instrumental analysis and reaction mechanisms. It includes analysis results from infrared (IR) devices, data analysis, and reaction mechanisms, starting with the material polyamide-imide. While the storage stability of raw materials is essential in product manufacturing, environmental conditions during the processing can sometimes induce defects. We encourage you to read on.

Useful for quality control over the years! Ultra-micro hardness measurement of materials such as metals, polymers, and ceramics.

Our "Ultra-Micro Hardness Measurement for Material Evaluation" allows for the ultra-micro hardness measurement of materials such as metals, polymers, plastics, and ceramics. Additionally, since hardness can be quantified, it is also useful for long-term quality control. The hardness is determined by directly reading the depth of the indentation while applying a load to the indenter. It is also possible to determine characteristic values related to recovery behavior. 【Device Overview】 ■ Test force range: 0.4mN to 1000mN, Accuracy: ±0.02mN ■ Indentation range: 1nm (0.01μm) to 700μm *For more details, please refer to the PDF document or feel free to contact us.

Leave it to us for everything from chemical analysis and physical testing to reliability testing! Introduction to our measurement and evaluation services.

Plastic extrusion/injection molding processing is set according to the heat resistance temperature (melting point Tm) of the raw materials; however, due to the degradation and alteration of the materials, there are cases where molding becomes difficult at the specified setting temperature. By checking the melt flow rate (MFR) of plastic raw materials in pellet or powder form, it is possible to determine whether there are any changes compared to conventional products. We present a case where untreated (no load), temperature and humidity load (constant temperature and humidity test), and UV-irradiated PP (polypropylene) were injected and evaluated at a temperature of 230°C and a load of 5kg, so please take a look at the PDF download. [Evaluation Case] ■PP: Polypropylene ■8585: 85°C 85% × 336 hours ■UV: UV irradiation 253.7nm × 336 hours ■Injection time: 10 minutes (converted from 3 minutes) *For more details, please refer to the PDF document or feel free to contact us.

Essential materials alongside metals and inorganic materials! Introducing examples of analysis and evaluation services for organic materials.

Organic materials such as solvents, additives, pharmaceuticals, and plastics are essential materials alongside metals and inorganic materials. They have a wide variety of types due to the combination of light elements, and their specificity is manifested through structure, intermolecular forces, and electron behavior. However, it seems that chemical instrumentation analysis and evaluation are necessary for a fundamental understanding of their properties. This document presents case studies of analysis and evaluation services for organic materials.

The analysis device also supports the analysis and evaluation of polymers! Information on the configuration and principles of high-temperature SEC equipment is included!

The molecular weight of resins such as plastics is not a single value but is composed of multiple molecular weights. By understanding this molecular weight and its distribution, it leads to a better understanding of the mechanisms and theories related to the properties and degradation of resins. In this document, we will introduce a case study where we measured polypropylene resin (PP) samples with and without ultraviolet (UV) irradiation using a high-temperature GPC device suitable for measuring polyolefin-based materials that are difficult to dissolve in solvents at room temperature, and conducted data analysis. We encourage you to read it. 【Contents】 ■ Configuration and principles of high-temperature SEC ■ Analysis case: Molecular weight measurement of PP subjected to UV irradiation ■ Application examples ■ Specifications and considerations for high-temperature SEC *For more details, please refer to the PDF document or feel free to contact us.

A karaoke bar located in Tokyo has introduced Majesta Fragrance. The scent that gently spreads upon entering elevates the overall impression of the establishment. The fragrance, which is regularly sprayed from the diffuser, creates a comfortable atmosphere. Majesta Fragrance's commercial aroma diffuser rental service is available starting at 4,400 yen per month. A one-week free trial installation is also possible before signing a contract. If you are interested in scenting your space, please feel free to contact us.

[To the owners of parking lots and parking lot construction companies] "I am worried about the possibility of colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those particularly facing sidewalks or roadways are expected to pose risks of dangerous incidents such as pedestrian collisions and vehicle-to-vehicle accidents. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures at various sites and alerts the surrounding area with LED lights and buzzers. The system consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *When using the exit warning system, we kindly ask that you arrange for the switching power supply (24V), LED rotating light, control panel, circuit breaker, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. [Contents Included] ○ Exit Warning System Configuration ○ Comparison Table of Exit Warning Sensors ○ Four Modes ○ Wide Range of Applications ○ Customer Feedback ○ Appearance Diagram / Specifications ◎ For more details, please contact us or download the catalog.
