Hiyama Industry Co., Ltd.

Our mainline businesses are film processing, weak adhesive coating, and optical part manufacturing.

Our company has three core businesses: film, metal and tape processing; weak adhesive coating; and optical part manufacturing. We mainly slit original thin film materials in our film, metal, and tape processing business. We coat adhesives on films in our weak adhesive coating business. This business includes corona treatment, lamination, rewinding, and other kinds of processing or treatment before and after coating. We manufacture optical fiber arrays, which are essential for optical communications, in our optical part manufacturing business. Our company has many customers, including major manufacturers such as Hitachi Chemical and NTT Electronics. We will expand our business overseas by making use of our sites in China.

Sales Pitch

Our goal is to be a unique and sought-after company We are a leader in the slit processing industry. We will make use of our achievements to continue to provide high-quality products that we take pride in before the world as a specialist with support and technical capabilities capable of satisfying every request.
Film, metal, and tape processing: 
◆We slit original material with a thin film shape. We manufacture separators for lithium-ion rechargeable batteries, and also various insulating materials, copper foils, and composite materials.
◆Our company has ordinary air-conditioned rooms and also Class 10000, 5000, and 1000 cleanrooms.
◆We perform visual inspections according to strict check items and deliver products with thorough quality management.
Manufacturing weak adhesive coating products: 
◆Our company mainly manufactures protective films used in LCD panel processing and storage. Our main products include functional films, polarizing plate films, and other films used for touch panels of various digital equipment. We also manufacture UV tapes that are used to process thin glass materials for precision equipment.
◆Our main equipment consists of large coating machines, but we also have small coating machines with higher universality. We handle mass-production orders, and also small-quantity production orders for prototyping or other purposes.
◆We also handle treatment and processing before coating, such as corona treatment to improve material wettability, lamination, and rewinding.
Optical part manufacturing: 
◆Our company manufactures optical fiber arrays that are indispensable for optical communications. This is done under an integrated manufacturing system from part machining to assembly, polishing, and product inspection. High-accuracy groove processing has realized fiber-pitch product manufacturing with extremely high accuracy.
◆We have a track record of manufacturing optical parts such as polarization-maintaining (usually called PANDA) fiber arrays and other products with special specifications. These include articles with super multiple cores, micro size, and irregular pitch.
◆We take on orders for long-term mass production, and also small-lot production for R&D or prototyping.

[Company structure for market development/overseas expansion]
We will review our production system in Japan because product quality is improving and labor costs increasing overseas. We will improve the quality of our relationships with customer companies through technical exchanges by giving top priority to further quality improvement. We will then review our work procedures at each process to further improve efficiency. We will increase our domestic sites to build up a system capable of quickly satisfying more customer requests. We will also continue our efforts to establish and grow our business overseas by making the most of our sites in China.
