FUJI SEIKI Co.,Ltd Product Lineup

Delivering peace of mind, Fujiseiki's "High Cycle Molds." Excellent disassembly/assembly characteristics and outstanding maintenance capabilities. Expanded from 4-cavity to 8-cavity using the same size molding machine, achieving a cycle time of 5 seconds with a 280t molding machine. The conventional 220t mold for CD cases, which had a cycle time of 8 seconds, has dramatically improved productivity to 8-cavity 280t with a cycle time of 5 seconds in our specifications. Additionally, by transitioning from the conventional cold runner structure (22 seconds) to a fully hot runner system, we have achieved high-speed molding in 15 seconds. This contributes to reducing runner waste and supports high cycle production. Furthermore, we support further efficiency improvements with the following technical proposals: ■ Runner-less design: Reducing resin waste & enabling high cycles ■ Optimization of product shape and runner: Improving release and cooling properties ■ Material changes: Enhancing thermal conductivity for better cooling efficiency ■ Cooling circuit optimization: Design based on thermal analysis and flow analysis *For more details, please download the PDF or feel free to contact us.

We introduce the high-efficiency "mold" solution from Fuji Seiki that delivers peace of mind. The key feature is the ability to achieve the maximum number of parts produced with molding machines of the same size. In the case of medical components, where it has been difficult to increase the number of parts with conventional molding machines, our company has significantly improved the production volume per unit time even with molding machines of the same size by optimizing the structure and flow path design. For example, the syringe (lock) mold accommodates 48 parts, and the needle cap (hot runner) mold accommodates 144 parts. As a result: - Productivity increased by 150% with existing molding machines - Expansion of production volume with one size smaller molding machines - Minimization of molding equipment investment costs 【Main Features】 ■ High number of parts: Syringe 48 parts / Needle cap 144 parts compatible ■ Compatibility: High-efficiency operation with the same size molding machines *For more details, please download the PDF or feel free to contact us.

We introduce the features of Fujiseiki's "compatible molds" that deliver peace of mind. Designed with a focus on exchange precision, disassembly and assembly can be carried out smoothly. After replacing parts, production can be resumed immediately, significantly reducing line downtime. Furthermore, spare parts are ensured to have good quality regardless of which CAV they are used in, achieving efficiency in parts management and rapid recovery response. Maintenance has also become easier, contributing to reduced work time and avoidance of reliance on specific personnel. While alleviating the burden on operators, we support increased equipment operating rates. 【Main Features】 ■ Easy disassembly/assembly: Reduces work burden with minimal tools ■ Rapid production recovery: Line can be restarted immediately after part replacement ■ Improved maintainability: Shortens work time and increases operating rates ■ Compatibility among multiple molds is also realized, minimizing production downtime during troubles *For more details, please download the PDF or feel free to contact us.

Fujiseiki's "Mold for Minimizing Cavity Differences" delivers peace of mind and high precision. Even in mass production or multi-cavity operations, it minimizes dimensional differences across all cavities to the utmost limit, significantly reducing defect rates in subsequent processes. In mold processing, we thoroughly manage component precision, minimizing even slight processing errors. This effectively suppresses variations between individual products that are likely to occur during mass molding. Furthermore, during the mold design phase, we utilize flow analysis (CAE) to optimize the filling balance for each cavity, preventing resin flow irregularities that can lead to dimensional errors. ■ Features - Temperature distribution simulation: Achieves uniform temperature control across all cavities - Injection pressure sensor: Detects and corrects pressure variations in real-time - Three-dimensional measuring machine: Samples and centrally manages dimensional data - High-precision molding compatibility: Adapts to strict tolerances in fields such as medical and electronics *For more details, please download the PDF or feel free to contact us.

The "Confirmation TRY Mold" from Fuji Seiki has six molding machines ranging from 75t to 650t in-house, and conducts pre-TRY with actual injection for all molds. By completing mass production preparations during the prototype stage, from setting molding conditions to appearance evaluation, we achieve immediate startup and production stabilization after delivery. The maximum mold size can accommodate up to 1000mm. While based on 280t class molds, we can flexibly handle small to large parts. ■ Benefits of In-House Prototyping: TRY verification is conducted on all molds using in-house molding machines. All processes from mold operation, appearance evaluation, to setting molding conditions are completed in-house. Verification can be performed in a real environment close to the target cycle. Deliveries come with actual data, minimizing on-site trials. This is especially recommended for those struggling with trial and error or condition setting after implementation. By predicting issues and streamlining adjustment work, we support the quickest possible startup of mass production. *For more details, please check the PDF document or feel free to contact us.

Fujii Seiki's "High Cycle Molds" excel in disassembly/assembly and maintenance, making them exceptional precision molds. There are cases where the number of cavities has been expanded from 4 to 8 using the same size molding machine, achieving a cycle time of 5 seconds with a 280t molding machine. The CD case mold, which traditionally operated at 220t with an 8-second cycle, has seen a dramatic increase in productivity with our specifications, now achieving 8 cavities at 280t with a 5-second cycle. We would like to introduce examples of how we have supported further efficiency through technical proposals!
