若林工業 List of Products and Services

Unlike conventional bonding and machining, it is directly linked to 3D CAD, allowing for easy shaping of complex geometries and accurate verification of shapes. Additionally, by providing the 3D model along with CAD data or drawings, it is possible to prevent manufacturing errors in molds, reducing waste and cutting costs through optimal design. Furthermore, it aids the understanding of the final product manufacturing personnel, helping to prevent mistakes during the manufacturing process, which can lead to reduced time to market and decreased waste. The 3D modeling can be used for checking assembly and fitting of parts, as well as for functional considerations such as mechanisms and simulation experiments. By conducting functional evaluations, design errors can be avoided, enabling more appropriate designs. The results of these considerations can be easily fed back into manufacturing design.

By creating a three-dimensional model through light shaping, it becomes possible to physically examine whether the design of the product meets expectations and to receive evaluations from others. Furthermore, the results of this examination can be fed back into the design. Unlike traditional methods such as assembly or machining, this process is directly linked to 3D CAD, allowing for easy creation of complex shapes and accurate verification of the design. Additionally, by providing the three-dimensional model along with CAD data or drawings, it is possible to prevent errors in mold production, thereby reducing losses and achieving cost savings through optimal design. [Case Study] ■ Material: Light-shaping resin, sheet metal painted parts ■ Industry: AV equipment-related ■ Work size: 100×100 ■ Plate thickness: Resin t1.5 / Sheet metal t0.8 *For more details, please download the materials or contact us.

Compared to the conventional machining method using cutting tools for producing three-dimensional objects, the following advantages of light shaping methods can be highlighted. **Advantages of Light Shaping** - It is easy to create three-dimensional shapes with free-form surfaces and complex structures (such as undercuts) that are difficult to achieve with conventional cutting processes. - Desired models can be produced quickly and economically. **Applications of Light Shaping** - Design models, working models, master models, wooden molds, resin molds, lost-wax masters, vacuum casting masters, small production parts, vacuum casting molds, direct injection molding molds. - As three-dimensional copies: human body models, shoe lasts, three-dimensional maps. - In the medical field: surgical simulation models, prosthetics, educational training models. **Case Study** - Material: Light shaping resin - Industry: Home appliances - Work size: Φ300 - Plate thickness: t2.0 *For more details, please download the materials or contact us.*

In the precision/prototyping sheet metal and laser department, we perform laser processing, bending, spot welding, and other types of processing. We can cut materials such as iron, stainless steel, aluminum, phosphor bronze, and brass. For SUS, we can achieve clean cuts (oxidation-free cutting) from t=0.05mm to t=6.0mm, and up to t=3.0mm for clean cuts. The materials we handle include SPCC (up to 3.2t), SPHC (t=4.0 to 6.0), SECC (GX material up to 2.3t), aluminum 5052S (up to 3.0t), and SUS304-2B (up to 6.0t). We also work with various spring materials such as SUS430, SUS631, and SUS301/SUS304, as well as phosphor bronze, SK materials, and ribbon steel. The HV2-R laser processing machine can also handle pure copper and pure aluminum processing up to about 2.0t. We always keep a variety of materials and plate thicknesses in stock, allowing us to respond to short lead times and urgent orders starting from just one piece. [Example] - Material: SUS304 - Industry: Medical equipment related - Work size: 400×50 - Plate thickness: t1.0 *For more details, please download the materials or contact us.
