日本通信電材株式会社TECHNOLOGY技術情報

耐候性が要求されるクロージャをはじめ、屋外用接続箱・超精密射出成形品・大型射出成形品など、多岐に渡る開発実績を通して「材料選定」のノウハウを蓄積。用途や使用環境に適した材料を選定することで、お客様満足度の高い製品をご提供しています。

特殊プラスチック材料の採用により、太陽光の赤外線を反射し熱の吸収を抑え（熱吸収量：一般樹脂約50％・Ｎ-PAS約5％）、BOX内部の温度上昇を抑制。真夏環境でも内部温度を50℃以下に抑えられるため（※3）、放熱ファンレス・メンテナンスフリーでの運用が可能です。

We have accumulated know-how for material selection through a broad range of development fields, such as those involving closures which requires weather resistance and outdoor joint boxes, nano- and large-injection molding products. Our experience enables us to select the best material for any given application and environment to deliver excellent products for customers.

The unique plastic used for this cabinet reflects solar infrared rays and governs the heat absorption (heat absorption rates: general resin = about 50%; N-PAS = about 5%), controlling the rise in temperature within the box. This feature allows suppression of the internal temperature at 50 degrees C or lower even in the middle of summer3, eliminating the need to install cooling fans and maintenance.

当社は長年培った射出成形技術と光ファイバの配線設計技術を融合させた『プレ配線製品』を得意としています。プレ配線製品のメリットは「小型化・高密度化・作業性向上」と、これらの効果によるお客様の作業負担軽減・コスト低減です。コネクタ・アダプタ部品の製造技術やコネクタ結線技術を持つ当社だから提供可能な高品質な製品です。既存製品のみならず、お客様のご要望に合わせた新たなプレ配線製品も開発可能です。

クロージャや光接続箱等へ光スプリッタやコネクタ付き心線の実装をあらかじめ工場で行い出荷するものです。現地での取付・配線作業が不要となり、作業時間が短縮できます。また、光スプリッタのテープ心線の単心分離処理、FOコードの外被除去などファイバ周りの繊細な作業工程を省略でき、作業者様の負担軽減にも貢献します。

One of our strengths is the manufacturing of pre-terminated products that integrate our long-standing injection molding technology with our optical wiring design technology. Pre-terminated products bring about compactness, densification, and enhanced workability. These factors have allowed customers to reduce workloads and costs. We can produce such high-quality products only because of our trusted production technology relating to connectors and adapters, including connector connection technology. We are always ready to make pre-terminated products tailored to the needs and demands of customers.

A pre-terminated products are such as a closure or optical connection box that comes with optical splitters and connector installed fibers installed in before shipment. This eliminates on-site installation and wiring work, reducing work time. Operators can also reduce their workloads by skipping delicate processes relating to fibers, such as single-fiber separation for ribbon fiber of the optical splitter and sheath removal for Fun-Out cords.

当社では、通信用土木製品・光ファイバ配線部材・光通信向け超精密射出成形部品などの開発・製造において蓄積された知見を活かし、新市場にも積極的に挑戦しています。長寿命で知られるレドックスフロー電池には、20年のシステム耐久性が求められ、使用される部品は長期信頼性と高い寸法精度が要求されます。当社では、製品サイズが1mを超える大型でかつ薄型の射出成形部品でありながら、反りを含み厚さ方向で数十ミクロンオーダーの寸法公差を達成。開発速度が著しい新市場においても、豊富な経験による射出成形材料提案、流動解析による金型設計技術提案は、お客様より高い評価を得ています。

We actively explore new markets taking advantage of knowledge accumulated through developing and producing civil engineering products for communications, optical fiber wiring components and ultra precision-injection molding products for optical communications.
Redox flow batteries, well known for their long life, call for 20-year system durability, in situations in which long-term reliability and high dimensional measurement precision are required. We achieved dimension tolerance of several dozen microns in terms of thickness, including warping, even for large and thin injection molding products exceeding 1 m in product size. In new markets characterized by rapid development speed, we have received high marks from customers for our injection molding material proposals based on our rich experience, as well as mold design technology proposals based on flow analysis.
