We would like to introduce the equipment "Sheet Metal" of Union Maeda Co., Ltd. By combining the three processes of "cutting, bending, and attaching," we transform steel plates into various shapes. We have two laser processing machines, three NC benders, two hydraulic brake presses, and two robotic welding machines, allowing us to handle a wide range from prototyping to mass production. In particular, we produce many medium-thick plates with a thickness of approximately 3.2 to 6.0 mm, and our uniqueness lies in the complex processing that collaborates with other processes. 【Features】 ■ Capable of handling a wide range from prototyping to mass production ■ Particularly many products of medium-thick plates with a thickness of approximately 3.2 to 6.0 mm ■ Uniqueness through complex processing that collaborates with other processes *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the equipment "Press" of Union Maeda Co., Ltd. This process involves setting molds that correspond to various types of processing such as "cutting, drawing, forming, and bending" to process steel plates with a press machine. With two lines, a 150-ton thin plate line and a 300-ton thick plate line equipped with a coil feeding device, it is possible to continuously perform blank (cutting) processing from coils. We have a 200-ton servo press, a 300-ton link motion press, and a 500-ton hydraulic press, and since other presses are also equipped with die cushions, we excel in processes such as drawing and forming. 【Features】 ■ The two lines, a 150-ton thin plate line and a 300-ton thick plate line, enable continuous blank (cutting) processing from coils. ■ Equipped with die cushions, we are skilled in processes such as drawing and forming. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case where Union Maeda Co., Ltd. manufactured the "bonnet" component for industrial valves. The manufacturing process consists of 1. machining (small parts), 2. welding, and 3. machining (finishing). Due to significant challenges posed by welding distortion and deformation, we were able to overcome these issues by effectively combining our in-house welding and machining technologies. 【Case Overview (Partial)】 ■Challenges - Significant impact from welding distortion and deformation ■Results - Overcame challenges by utilizing a combination of in-house welding and machining technologies *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case where Union Maeda Co., Ltd. manufactured a part called a "bracket" that supports the shaft of a truck. This is a very ambitious challenge to produce a complex welded structure from thick plates using integrated press forming. Ultimately, we succeeded in mass production manufacturing with dimensional tolerances secured through a press method consisting of a total of 10 processes. 【Case Overview】 <Technical Elements> ■ Plastic processing through multiple processes of 4.5mm thick steel plates ■ Mold technology *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case where Union Maeda Co., Ltd. manufactured a "V Pulley," a power transmission component utilizing V-belts. We proposed a method that included a design change from the customer's conventional method (a split pulley with a thickness of 3.2mm) to our method (roll forming with a thickness of 1.6mm). We suggested a shape that satisfies both our product specifications and the dimensions required by the customer, which was adopted. Our strength lies in providing a total proposal that includes processing of the boss, keyway and spline machining, welding, and surface treatment. [Case Overview] <Technical Elements> ■ Roll forming technology ■ Product design *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case where our company manufactured "stiffeners" for truck bed pillar components. The customer's blanking process involved total punching with an NC turret punch, which resulted in poor material yield, high processing costs, and long lead times. In response, we designed and developed a mold that uses the material width of the coil as the product width, allowing for changes in the feed amount to adjust the product length. As a result, we were able to accommodate all similar products with varying lengths, significantly improving material yield, reducing processing costs, and enabling shorter delivery times. [Case Overview (Partial)] ■ Issues - The blanking process involves total punching with an NC turret punch, leading to poor material yield, high processing costs, and long lead times. - There are multiple similar products in the product lineup that only differ in length. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case where Union Maeda Co., Ltd. manufactured a "tube pipe" connector for exhaust lines for construction machinery. Since the investment for press molds is significant for mass production, we first considered prototyping using low-investment methods such as draw forming. The 2mm thickness of the stainless steel plate posed challenges, but the prototype was successfully completed. Having cleared the testing evaluation, we moved on to the mass production stage. We achieved good yield and successfully implemented plastic processing with low load on subsequent processes. [Case Overview] <Technical Elements> ■ Forming by draw forming (prototype) ■ Press method and mold technology (mass production) *For more details, please refer to the PDF document or feel free to contact us.

The manual 3-axis measuring instrument MD series is a 3-axis measuring device that allows for easy measurement of medium to large parts with a maximum stroke of 2500×1000×450h. It significantly reduces measurement time through the combination of calipers, height gauges, block gauges, scales, and more. Measurements can be taken easily by hand without the need for programming work. Additionally, the coordinate positions are displayed digitally on the counters of each axis. For more details, please contact us or refer to the catalog.

We are in an era of hybrid dominance, but since we changed our company name to Union Maeda, we have been aiming for the integration of processing technologies. We believe this has culminated in the production of parking stop units for coin-operated parking. Moving forward, we intend to achieve further transformation by enhancing individual processing technologies while also adding assembly techniques and control systems.
