Reconditioning of Industrial Sigma Kneader Mixers

RMC Marc Guittard’s historical expertise in ensuring the long-term performance of equipment

Refurbishment is part of RMC Marc Guittard’s DNA. Since its founding in 1994, the company has specialized in the repair, renovation, and modification of Sigma Kneader Mixers, Extruder Mixers, and Industrial Mixers intended primarily for industries handling high- and very-high-viscosity products.

This long-standing activity has enabled the company to develop in-depth knowledge of mixing equipment, its design, operation, and evolution over the decades. Long before designing and manufacturing its own machines, RMC Marc Guittard was already working on equipment in service to restore its performance, improve its reliability, and meet the new requirements of manufacturers.

Even today, reconditioning remains a core area of expertise for the company. It allows us to offer a high-performance, sustainable, and cost-effective alternative to the routine replacement of equipment, while ensuring a level of performance that meets users’ expectations.

Expertise Built Around Industrial Processes

Reconditioning an industrial mixer involves more than just replacing a few wear parts.

It is a comprehensive process that requires an understanding of the manufacturing process, an analysis of the machine’s performance during production, and identification of the causes of its wear and tear.

For more than three decades, the RMC Marc Guittard teams have been working on equipment used in particularly demanding industrial sectors:

  • chemical industry,
  • elastomers and polymers,
  • RTV and HTV silicones,
  • food processing,
  • cosmetics,
  • pharmaceuticals,
  • engineering materials and composites.

 

This field experience now forms one of the foundations of RMC Marc Guittard’s expertise.

A thorough technical analysis before any work begins

Every project begins with a comprehensive inspection of the installation.

Specialized technicians conduct a diagnostic evaluation to precisely assess the machine’s overall condition as well as the performance of the mixing process.

This analysis focuses on:

  • the mixing tank,
  • the mixing blades,
  • the shafts and transmission components,
  • the gearboxes and motors,
  • the bearings,
  • the sealing systems,
  • the electrical equipment and automation systems,
  • the mechanical and thermal performance of the system.

 

This evaluation phase allows us to determine the reconditioning procedures best suited to the customer’s production objectives.

 

Reconditioning carried out in our workshops

After complete disassembly, each component is inspected according to rigorous procedures.

Depending on its condition, it may be:

  • repaired,
  • remanufactured,
  • replaced with an original or equivalent part,
  • upgraded to improve the system’s performance.

The subassemblies are then reassembled, adjusted, and inspected prior to functional testing conducted in our workshops.

This methodology ensures a high level of quality, reliability, and safety before the equipment is returned to service.

Restoring performance while incorporating technical advancements

Refurbishment also provides an opportunity to upgrade equipment.

Depending on your needs, the RMC Marc Guittard teams can integrate:

  • new drive systems,
  • more efficient transmission systems,
  • modernized automation systems,
  • safety features compliant with current regulations,
  • mechanical improvements designed to optimize mixing performance,
  • heating, cooling, or vacuum operation solutions.

This approach enables the equipment’s service life to be extended sustainably while meeting new industrial requirements.

Complete Traceability

One of RMC Marc Guittard’s historic strengths lies in its maintenance of technical data for its equipment.

Every service call is documented to ensure complete traceability:

  • 2D drawings and 3D models,
  • parts lists,
  • technical data sheets,
  • manufacturing parameters,
  • service history,
  • replaced parts,
  • technical upgrades performed.

This documentation database facilitates future maintenance, renovation, or modernization operations, even for equipment that has been in service for several decades.

A sustainable approach to serve manufacturers

Refurbishment fully addresses today’s challenges of industrial performance and sustainable development.

By extending the service life of existing equipment, it makes it possible to:

  • preserve industrial investments,
  • minimize production downtime,
  • reduce costs associated with replacing equipment,
  • maximize the value of existing equipment,
  • reduce the environmental footprint of industrial projects.

This approach aligns with the principles of the circular economy by giving a second life to equipment designed to last.

Expertise that drives innovation

The hundreds of machines that have been expertly assessed, disassembled, refurbished, and modernized since the company’s founding constitute a unique technical legacy.

This in-depth knowledge of mixing technologies, mechanical constraints, and industrial processes directly contributes to the work of the engineering department.

Each reconditioning project provides valuable experience for our teams and helps develop new solutions that are increasingly efficient, reliable, and suited to the needs of manufacturers.

Long-term support

Some of the installations monitored by RMC Marc Guittard are still in operation after several decades of service.

This longevity is a testament not only to the quality of the equipment but also to our teams’ ability to provide technical support, maintenance, modernization, and refurbishment throughout the equipment’s lifecycle.

Because each facility represents a strategic investment, RMC Marc Guittard partners with its customers in a spirit of long-term collaboration, offering customized solutions to maintain the performance of their equipment year after year.

Refurbishment means sharing expertise

Refurbishment is much more than a technical service. It is a craft that requires a thorough understanding of industrial processes, high-level mechanical expertise, and in-depth knowledge of mixing equipment.

As part of the company’s long-standing legacy of expertise, this skill continues to make a difference today. It enables RMC Marc Guittard to help manufacturers preserve their equipment, optimize its performance, and ensure the lasting value of their investments, both in France and internationally.
