This time, we will focus on stamping processes and explain a simple method for selecting materials suitable for stamping for designers.

Rational material selection enables the design of products that are easy to manufacture, leading to reduced costs due to fewer processes, improved productivity during mass production, and enhanced reliability and durability of the products. Designs with high forming difficulty will increase material and processing costs. Indicators of material properties for evaluating materials suitable for stamping include tensile strength, yield strength, elongation, hardness, Erichsen value, limiting drawing ratio, and conical cup value. However, two specific characteristic values that can directly evaluate formability are as follows: 1. The n-value representing work hardening characteristics 2. The r-value (Rankford value) representing anisotropy The n-value and r-value are characteristic values that directly relate to the quality of actual stamping processes, and this evaluation allows for the selection of appropriate materials. *For more details, please download the PDF or contact us.*

This document explains the key points of material selection.

In the process of spring design, once the stress level of the required material is determined, it is necessary to select a material that possesses those characteristics, and an understanding of the properties of the material is crucial.

This is a collection of examples of drawing processes manufactured with progressive drawing dies using automatic press processing! Shall we solve your problems with drawing processes together?

A drawing die refers to a type of mold used in a processing method that creates various shapes of bottomed containers, such as cylinders, rectangular tubes, and cones, from a single thin sheet of metal. A characteristic feature of the formed products is that they have no seams. It is said to be the highest level of press processing. We would like to introduce a case study using our progressive die that has actually solved customer problems! Our products are primarily made using automatic press processing, ensuring stable quality, cost performance, and short delivery times, allowing us to meet customer demands. Please feel free to download it.

We will introduce the implementation results of the sensor technology developed by the Hotron Group, which has been cultivated over more than half a century, through customer case studies. In addition to automatic door sensors, we also offer a wide range of vehicle detection sensors and nursing/care sensors. Many implementation examples are also presented, so please take a look at the case study page.

Parking space management refers to the real-time display of parking availability and the management of efficient use of parking spaces. By utilizing Hotron's sensors, drivers can quickly discover available parking spaces, enabling efficient parking lot operations. For large parking lots, we recommend the "Floor Management Method" and "Block Management Method," which focus on cost reduction. Sensors are installed at regular intervals to count and manage the number of passing vehicles. This method offers the advantages of easy installation and low costs. 【Target Products】 - Vehicle Count Sensor CCS2 - Ultrasonic Sensor HM-UX2/UW2 For smaller facilities, we recommend the "Parking Space Management Method," where sensors are installed in each parking space to display availability with high accuracy. By providing reliable occupancy information, this method helps reduce unnecessary entry of new vehicles and ensures safe parking lot operations. 【Target Products】 - Occupancy Detection Sensor HM-UX2/UW2 - Occupancy/Pass Detection Sensor HM-LC6 - Occupancy Detection Sensor HM-LC7/LC7-FLS - Occupancy/Pass Detection Sensor HM-S6 - Occupancy Detection Sensor HM-S8
