IER Fujikura

What IER Fujikura does

IER Fujikura, Inc. is a US-based custom manufacturer of engineered molded rubber components and sealing solutions, founded in 1958 as Industrial Electronic Rubber and headquartered in Macedonia, Ohio. Since 2006 the company has operated as a wholly-owned subsidiary of Fujikura Composites Ltd. (Japan), giving it access to a global manufacturing footprint spanning Japan, China, and Vietnam. The company employs between 51 and 100 people and operates over 50 production presses across three shifts in its Ohio facility.

The company's core competency is the formulation, molding, and bonding of high-performance elastomers, including fluoroelastomers (Viton, Fluorel, Technoflon), HNBR, silicone, EPDM, nitrile, and perfluorelastomer compounds. Manufacturing capabilities span compression, transfer, injection, and proprietary Liquid Silicone (LIM) molding performed in cleanroom environments, with vulcanization bonding of rubber-to-metal and rubber-to-plastic, plastic injection molding, surface treatment, and CFRP processing. The product portfolio includes diaphragms (flat and rolling/BF types), duckbill and umbrella valves, flow regulators, air regulators, air cylinders, check/relief/needle valves, and custom engineered seals. Quality and regulatory credentials include ISO 9001, IATF 16949, ISO 14001, ISO 13485, ISO 17025, and ISO 10993 with USP Class VI material compliance.

IER Fujikura serves five end markets, with automotive and medical as primary verticals, and residential/commercial products, general industry, and aerospace as secondary segments. Customers are enterprise OEMs and Tier suppliers requiring mission-critical sealing for fuel systems, emission controls, dialysis machines, oxygen concentrators, ventilators, insufflators, analytical instruments, and industrial pumps. The company runs a sales-led GTM with dedicated product managers per project delivering cradle-to-grave engineering support from concept to delivery, pricing on a quote-basis per project rather than via published rates. Visual inspection (Basler and DOSS), ultrasonic mold cleaning, and cleanroom LIM underpin its quality positioning.

Products and services

• Air Cylinders Mechanical devices which use compressed gas to produce a force in reciprocating linear motion, equipped with BF Diaphragm for leak-proof operation with virtually no hysteresis loss; sold to industrial and OEM customers.
• Air Regulators Devices for reducing high-pressure fluid or air supply lines/tanks to safe and usable pressures; available in RS, RR, RP, RP1, RP2, RG1, RA/RB, RV, RV2, and RS Clean Room series.
• Diaphragms Flexible seals that prevent unwanted transmission of substances between two places, used for pressure controlling, barrier membrane, and sealing functions; includes flat and rolling diaphragm types.
• Duckbill Valves One-piece elastomeric components that act as backflow prevention devices or one-way check valves, with duckbill-shaped lips preventing backflow and allowing forward flow.
• Flow Regulators Constant flow regulating valves that control water flow, maintaining discharged water flow at a fixed rate regardless of input pressure; available in E type and A type with flows from 1 to 21 liters.
• Rolling Diaphragms BF Diaphragms shaped like top hats combining bellows and diaphragm properties, enabling smooth rolling action with long stroke capability; available as rubber only or composite with fabric.
• Rubber to Metal Bonded Products Vulcanization-bonded products of rubber and metal or rubber and resin, creating higher adhesive reliability than post-bonding through bonding agent application before vulcanization.
• Umbrella Valves Precise check valves with elastomeric diaphragm-shaped sealing disk or umbrella shape, providing immediate positive seal, position-independent operation, high flow rate, and corrosion resistance.
• Check/Relief/Needle Valves
• Custom Engineered Rubber Products Custom engineered rubber products using fluoroelastomers (Viton, Fluorel, Technoflon), HNBR, Fluorosilicone, Silicone, Nitrile, Polyacrylate, EPDM, Neoprene, Hydrin, and Butyl; includes design input and compound expertise.
