ムトウ List of Products and Services

We will be exhibiting at the "10th IPF Japan 2023 (International Plastic Fair)" held at Makuhari Messe. In recent years, as overseas production has accelerated, we have made it possible to produce molds of the same quality at our three locations: Tokyo (headquarters), Yamagata (Shinjo), and China. We are also able to challenge the demands for shorter delivery times and cost reductions through product unit orders. Our booth number and other detailed information will be announced in July. Please feel free to reach out with any questions. We sincerely look forward to your visit. 【Event Overview】 ■ Dates: November 28 (Tuesday) to December 2 (Saturday), 2023 (5 days) ■ Hours: 10:00 AM to 5:00 PM (until 4:00 PM on the last day) ■ Admission Fee: - Free for those who pre-register online or bring an invitation ticket - On-site registration on the day will incur a registration fee of 1,000 yen (including tax, valid for 5 days) *For more details, please refer to the related links or feel free to contact us.

In this document, we provide a detailed explanation of molds. Molds are used for shaping materials such as metal, plastic, rubber, and glass for the production of specific products, and the quality of the mold determines the quality of the final product. Our company specializes in the design and manufacturing of plastic injection molds, offering total support for the production of plastic injection molded products, from product design to mass production molding, secondary processing such as painting, plating, and silk printing, assembly, and delivery according to your specified methods. Please feel free to contact us. [Contents] ■ What exactly is a mold? ■ Producing many identical shapes ■ Taiyaki also utilizes "mold" technology ■ Mass production *For more details, please refer to the PDF document or feel free to contact us.

"Injection molding for shaping the bodies of laptops and mobile phones" and "FRP molding for creating large shapes like ships" are just a few examples of the many plastic products around us, each utilizing various molding methods depending on their shape and material. Muto Co., Ltd. manufactures injection molds tailored to various materials, which are essential for industrial products. For more details, please visit our website. We encourage you to check it out through the related links below. 【Various Molding Methods】 ■ Injection molding for shaping the bodies of laptops and mobile phones ■ Blow molding for PET bottles that expand like balloons with heated resin ■ FRP molding for creating large shapes like ships ■ Sheet metal forming for producing metal bodies of cars *For more details, please refer to the PDF materials or feel free to contact us.

With the recent trend of "miniaturization" seen in many home appliances, more precise processing of molds is required. To manufacture precise molds, new advanced processing machines capable of precision machining and measuring instruments to verify processing accuracy are necessary. At Muto Co., Ltd., we have introduced precision machining equipment such as the "Makino V56" and contact measuring instruments to meet our customers' needs. Additionally, to ensure close communication with our customers and to produce molds more quickly and with higher precision, we also manufacture molds in South Korea and China. For more details, please refer to the related links below. *For more information, please refer to the PDF materials or feel free to contact us.*

Muto Co., Ltd. spares no effort to stay at the forefront of the times. In order to provide the products our customers demand, we believe that communication with our customers is the most important aspect, in addition to technological research and the introduction of new equipment. Therefore, we are promoting the unification of our manufacturing lines, which have been previously divided into specialized roles. In the traditional product development process, where "mold manufacturers handle mold production and molding contractors take care of product shaping," there have been issues where the identification of the cause becomes ambiguous when molding defects occur. Our company centralizes these processes, taking full responsibility from mold design to mass production molding and mold maintenance. This means our customers do not need to have multiple meetings with different contractors, which also leads to a reduction in development time. On our website, we introduce the mold industry that supports Japan's manufacturing sector. Please take a look at the related links below. *For more details, please refer to the PDF materials or feel free to contact us.

Many of the things around us are made of plastic. One reason for this is that plastic is an inexpensive material that is easy to mold and comes in various types with different properties. Industrial products are also aimed at mass production, so when it comes to how to make many identical items cheaply, efficiently, and with precision, molds have become an indispensable presence. On our website, we provide a simple explanation of what a "mold" is. Please take a look at the related links below. *For more details, please refer to the PDF materials or feel free to contact us.

The design philosophy of laptops has gradually changed to be thinner, lighter, and stronger since the early 1990s. The thickness of molded products has also been continuously reduced, and strength has improved due to advancements in the research and development of molding materials. On the other hand, regarding the appearance of products, there were restrictions on gate placement from the appearance side and thin walls, which inevitably required multi-point gating for filling. The mold structure devised to satisfy client requests is called the "Reverse Mold." The devised "Reverse Mold" allows for pin gate settings at any location from the back of the product and has a structure that protrudes from the fixed side. [Features] - The gate setting position is arbitrary - Can fill thin-walled molded products - Measured average wall thickness t=1.0 (A4 size) *For more details, please refer to the PDF document or feel free to contact us.

Muto Co., Ltd., which specializes in the design, manufacturing, and maintenance of plastic injection molds, presents a movie introducing the process of creating injection molds. Phase 7, the final step in mold manufacturing, involves setting the mold in the injection molding machine and checking whether the molded product is made according to the design specifications. This includes measuring and visually inspecting for dimensional accuracy, short shots, burrs, silver streaks, gas, and weld lines. *For more details, please refer to the PDF document or feel free to contact us.*

Muto Co., Ltd., which specializes in the design, manufacturing, and maintenance of plastic injection molds, presents a movie introducing the process of creating injection molds. Phase 5 is three-dimensional measurement. We check whether the parts of the mold we have produced are made according to the design dimensions. The measuring instrument used at Muto is Mitutoyo's 'Crysta-Apex C7106.' In addition to contact measurement, we also utilize probes that allow for image-based measurement. *For more details, please refer to the PDF document or feel free to contact us.

Muto Co., Ltd., which specializes in the design, manufacturing, and maintenance of plastic injection molding molds, introduces the process of creating injection molding molds in a movie. Phase 4 is electrical discharge machining. In electrical discharge machining, the workpiece and an electrode called a discharge master are brought close together in an insulated oil environment to create a discharge. In this step, edge shapes are added to the mold components that have been machined using a machining center. *For more details, please refer to the PDF document or feel free to contact us.

Muto Co., Ltd., which specializes in the design, manufacturing, and maintenance of plastic injection molding molds, introduces the process of creating injection molding molds through a movie. Phase 3 involves the actual cutting of the mold into its final shape using a machining center. Data designed in 3D CAD is sent, and the metal is machined at high speed and high precision. By using a ball end mill, which has a rounded cutting edge, it is also possible to perform machining on curved surfaces. The machine used in the video is the MAKINO V56. *For more details, please refer to the PDF document or feel free to contact us.
