About Us
With over 35 years of experience, ENRI designs and manufactures elastomer-covered industrial rollers and technical elastomer components for demanding environments.
Based in Normandy and founded in 1986, the company supports industrial customers in France and internationally, providing silicone, polyurethane, rubber and composite solutions selected according to the real operating constraints of each application, whether in food processing, energy, printing, metallurgy or other demanding industrial environments.
Our Team
ENRI relies on a human-sized team combining solid technical expertise developed since 1986 with the ability to adapt to the most demanding industrial constraints.
The company was founded by people with deep technical backgrounds, and this culture has been carried forward over the years. Today’s team brings together two complementary strengths: expertise built through decades of projects, in France and internationally, and a new generation bringing agility, fresh perspective and the ability to adapt to evolving industrial processes.
This transfer is first and foremost technical. The skills developed in the field, the formulations mastered and the processes implemented have been progressively captured, documented and refined. This allows ENRI to maintain a consistent level of technical excellence, whatever the application.
The experience gained internationally strengthens this ability to handle a wide range of projects, from design through to manufacturing and delivery, including in technically or logistically demanding environments.
This expertise is also reflected in our ability to guide material selection according to the specific constraints of each application
Constant Innovation
Solutions that evolve with industrial requirements
At ENRI, innovation is not limited to developing new solutions, it is part of a continuous adaptation to the requirements of industrial processes.
As production environments evolve, they place increasing demands on performance, durability and precision. In this context, roller covering and the manufacture of elastomer components require ongoing development of materials, formulations and processes.
ENRI develops its solutions by drawing on its in-house capabilities, in order to respond precisely to the specific constraints of each application.
Our developments are based on different families of elastomers : silicone (up to 280°C, food-contact grades available), polyurethane (abrasion resistance) and rubber (high-temperature resistance and specific chemical compatibilities), selected according to real operating conditions.
Each project is approached according to its actual use. This allows us to continuously refine our technical solutions and adapt our processes to the constraints observed in the field.
The rollers and components we manufacture play a direct role in the quality and consistency of the final product. This responsibility demands constant rigor in the design, manufacture and inspection of every solution we deliver.
Mr. Gilles Leblanc founds “Normandy Industrial Roller company”, known by its acronym – ENRI. Its initial vocation was the silicone coating of pressure rollers for the plastic industry.
Mrs. Marie Paule Leblanc joins the company and turns it into a family business.
The company leans on technical elastomers and turns high temperature issues into its specialty.
ENRI moves to its current site of more than 3,000 m², dedicated to the development and production of new products. The size of the new site has made it possible to set up a general mechanics section and a surface treatment unit (shot peening, sand blasting and micro-blasting).
An autonomous general mechanical workshop is created.
Mr. Romain Leblanc, founder’s son, becomes the general manager of the company.
A new cylindrical grinding machine is installed.
ENRI invests in a new injection machine, capable of continuous casting.
ENRI develops an innovative spraying process for elastomers.
ENRI develops a wider range of elastomeric molded custom-made parts.
ENRI invests in a large scale industrial oven and extends its production capacity.
ENRI is also certified by the Phytosanitary Compliance Program for wood packaging for export (ISPM 15).
ENRI replaced a thermal compressor with an electric and eco-friendly solution. The company had previously undertaken energy-saving efforts by installing a heat recovery system on an air compressor.
As part of its ongoing commitment to reducing its carbon footprint, ENRI transitioned its fleet of forklifts from gas-powered to electric.
Integration of a new high-precision lathe in our machining workshop, representing a new milestone in enhancing our production capabilities.
Strategic expansion of our production site: The installation of a new high-precision lathe, combined with a complete reorganization of the production line, now strengthens ENRI’s responsiveness and industrial performance.
ENRI welcomes SACD, a company specializing in rubber applications and derivatives, into its operations. Founded in 1988 by Mr. Raymond Degenne, SACD is a family business recognized for its expertise and flexibility in industrial cylinder coating. This acquisition marks a significant strategic enhancement of our skills in roller grinding and coating.
more than 35 years of experience in coating and steadfast determination to satisfy our customers.
Our permanent commitments
ENRI integrates environmental and social considerations into its operations and industrial decision-making.
The company has adopted a structured Corporate Social Responsibility framework in order to formalize and further develop actions already implemented over several years.
This approach is part of a continuous improvement process aligned with the realities of industrial activity, and aims to combine performance, sustainability and responsibility.
Frequently Asked Questions
When was ENRI founded and who leads the company?
ENRI was founded in 1986 in Épaignes, Normandy, by Gilles Leblanc under the name Entreprise Normande de Rouleaux Industriels.
The company has been led by Romain Leblanc since 2012 and continues to develop with a structured organization and a strong technical and industrial culture.
What materials does ENRI work with for industrial roller covering?
ENRI works with several families of elastomers, including silicone, polyurethane and rubber.
Material selection always depends on the specific constraints of the application, such as temperature, abrasion, chemical environment, pressure and contact conditions.
Depending on the formulation, silicone may be used in high-temperature environments, polyurethane offers strong abrasion resistance, and rubber provides specific compatibilities depending on the process.
ENRI also manufactures custom technical components by molding or injection, in a range of hardness levels from Shore A to Shore D depending on the application.
Can ENRI produce rollers compliant with food-contact requirements?
Yes. ENRI can provide solutions adapted to food-processing environments, particularly using silicones compatible with food-contact requirements.
Depending on the formulation, certain materials may meet the requirements of FDA regulations (21 CFR) as well as European Regulation (EC) No. 1935/2004.
Compliance depends on the selected formulation, operating conditions and the specific requirements of the application. Each project is assessed on a case-by-case basis to ensure material suitability.
What level of grinding precision does ENRI achieve?
ENRI performs precision grinding on elastomer-covered rollers.
Depending on the configuration, tolerances in the range of ±0.05 mm can be achieved, based on dimensions, materials and application constraints.
These capabilities are supported by in-house grinding equipment and strengthened by the integration of additional expertise following the acquisition of SACD.
Does ENRI offer re-covering of existing rollers?
Yes. Re-covering worn rollers is one of ENRI’s core services.
In many cases, when the metal insert is preserved, the roller can be stripped, re-covered and reground.
This solution provides an alternative to manufacturing a new roller, depending on the condition of the support and the application constraints.
Does ENRI export internationally?
Yes. ENRI has been operating internationally for many years and supports its customers in managing export-related logistics.
The company complies with ISPM 15 requirements for wooden packaging used in international shipments, ensuring conformity for global delivery.
