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, for 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.

• Plastic Mould

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 various 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 plastic injection molded products, from product design and mass production molding to secondary processing such as painting, plating, and silk printing, as well as assembly and delivery according to specified methods. Please feel free to contact us. [Contents] ■ What is a mold? ■ Making 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.

With the recent trend of "miniaturization" seen in many household appliances, more precise processing of molds is required. To manufacture precise molds, 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 facilitate 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 Corporation is committed to making every effort to stay at the forefront of the times. To provide the products our customers demand, we believe that not only is technological research and the introduction of new equipment essential, but even more importantly, communication with our customers is crucial. Therefore, we are promoting the unification of our manufacturing lines, which have previously been divided into specialized roles. In the traditional product development process, where "the mold manufacturer handles mold production and the molding contractor is responsible for product shaping," issues can arise where the identification of the cause of molding defects becomes ambiguous. 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.*

• Other molds

Many of the items around us are made of plastic. One reason is that plastic as a material is inexpensive, 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 produce many identical items cheaply, efficiently, and with precision, molds have become an indispensable presence. On our website, we provide a simple explanation of what "molds" are. 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 image shows a part of the mold used for the caps of plastic bottles that we use in our daily lives. The resin material is PP. We are mass-producing these daily, and we must perform maintenance efficiently and within a short timeframe. The image shows the mold parts before and after maintenance, and you can see that gas, tar, rust, and other residues have accumulated on the details of the parts. If we continue to use this mold as it is, it could lead to significant quality issues, such as defects in the molded products. We recommend regular maintenance of the mold.

• Plastic Mould

Recently, as the cost of molds has been either stable or on a downward trend, mold manufacturers are struggling to secure profits. A significant portion of the variable costs within the mold price comes from the main material cost of the mold base. Our company has focused on reducing this mold base to make it easier to secure profits compared to the current situation. To this end, we began producing mold bases in China about ten years ago, utilizing our office there. We are now receiving positive feedback from established customers. Our China office directly accepts orders and provides the products, with price advantages for sizes medium and larger. If you provide us with 3D data, we will process it based on that. Additionally, we offer 2D drawing services and provide the data in dxf format. In terms of quality, we ship based on various quality reports, backed by approximately ten years of experience.

The design philosophy of laptops has gradually changed to become thinner, lighter, and stronger since the early 1990s. The thickness of molded products has also become increasingly thinner and stronger, thanks 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 forced the use of multi-point gates 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, featuring a structure that protrudes from the fixed side. [Features] - The gate setting position is arbitrary. - It 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.
