• Injection Molding Machine

Injection flow control unit that can be widely introduced to plug gates and open-type hot runners.

The "RCSS18" is a hot runner molding device that can be easily assembled to the manifold, allowing for simple adjustment of the resin flow rate at each gate. Pursuing our fundamental development concept of "anyone can use it easily and with versatility," we focused on the ability to vary the outflow rate. It can be widely implemented not only in a plastic gate system but also in open-type hot runners, contributing to the overall cost reduction related to molds, including hot runners. 【Features】 ■ Easy adjustment of flow rate at each gate with just one wrench ■ Durable due to its simple structure ■ Suitable distribution of resin volume with large and small set takes and family molds ■ Easy movement and adjustment of weld positions ■ No need for auxiliary equipment such as dedicated controllers *For more details, please refer to the PDF document or feel free to contact us.

Prevent scorching caused by residual resin materials! A hot runner molding device that achieves runnerless molding at a low cost.

The "GTH Series" is a plunger gate open nozzle that can suppress injection defects caused by gate clogging and the occurrence of cold slugs. Thanks to the effect of the built-in special chip, it reduces stringing and dripping. Direct gate settings to molded products are possible. It has a low number of parts, excellent maintainability, and is easy to integrate into molds. 【Features】 ■ Eliminates issues unique to open nozzles ■ Structure with no stagnant areas ■ Clean gate finish ■ Simple structure ■ Achieves runnerless molding at a low cost *For more details, please refer to the PDF document or feel free to contact us.

Achieved complete runnerless design for super engineering plastics and biomass plastics, which have been considered difficult to convert to hot runner systems!

The "SEPT" hot runner system, compatible with super engineering plastics, significantly improves the long-standing issue of "uneven temperature distribution in nozzles" through a patented heating technology, making it suitable for resins with narrow temperature ranges, such as super engineering plastics and biomass plastics. By using wear-resistant materials for the parts, it can also reduce gate wear when working with glass fiber-reinforced resins. Additionally, by minimizing the size of the cylinder, it enables independent control of each gate with a minimum gate pitch of 30mm. Despite its compact design, the cylinder achieves a gate sealing force 3.5 times greater than conventional models by utilizing an oval shape and a double structure. *For more details, please refer to the PDF document or feel free to contact us.*

[Lecturer] Taku Ito, Partner, Mori Hamada & Matsumoto Foreign Law Joint Enterprise Yoshifumi Nagakubo, Senior Associate [Key Lecture Content] As we move towards a carbon-neutral society, the large-scale introduction of renewable energy sources is progressing, making the enhancement of market design that balances stable electricity supply and economic efficiency an urgent issue. In this context, the "simultaneous market," which integrates the trading of electricity (kWh) and adjustment capacity (ΔkW), is being discussed as a core component of future electricity systems, and serious considerations for its implementation are underway. In this lecture, a lawyer who has led discussions at the forefront of national system design will explain in an easy-to-understand manner the background and necessity of the simultaneous market, as well as the overall picture of its complex mechanisms, based on practical experience. Furthermore, the lecture will clearly outline the latest developments in current discussions, realistic challenges for implementation, and prospects for future electricity business in Japan, incorporating perspectives and insights as a system designer and practitioner.

[Instructor] Hirokazu Shibata, President and CEO of ZAZU Design Co., Ltd. [Key Lecture Content] As the importance of heat dissipation design increases in daily operations, it is necessary to study a range of books on thermal engineering to learn the overall picture of heat dissipation design. However, books on thermal engineering typically start with the basics of heat transfer and cover topics such as temperature boundary layers and dimensionless numbers related to heat transfer, making it quite difficult for beginners to grasp the overall picture in a short period. This seminar is aimed at engineers who will begin thermal design in the future, focusing on various heat dissipation devices as specific subjects. The goal is to understand the basics of thermal design while learning about the characteristics and usage of these heat dissipation devices. After attending this seminar, participants are expected to acquire knowledge equivalent to that gained from studying a range of thermal engineering books. [Lecture Topics] 1. Current Status and Challenges of Thermal Design 2. How "Thermal Resistance" Determines Heat Dissipation Pathways 3. Fundamental Laws Governing Heat Transfer 4. Air Cooling through Heat Transfer 5. Heat Diffusion through Thermal Conduction 6. Heat Transfer via Two-Phase Flow of Gas and Liquid 7. Q&A Session
