Neyret Group Assembly Solutions

The Neyret Group is an expert in complex, automated assembly processes and a leading automatic assembly machine manufacturer and designer. It also produces specialist control and printing machines for a broad range of clients, including pharmaceutical, medical device and medtech companies.

The group has earned worldwide acclaim for its innovative assembly machine design and manufacturing excellence, based on more than three decades of accumulated experience and technological advances.

As a specialist assembly solutions manufacturer, Neyret Group designs and produces a range of highly diverse machines; from pilot and semi-automatic machines to flexible robotic platform and cam-driven high-speed indexed or continuous motion industrial machines. Neyret Group’s core brand values are high precision, assured reliability and leading-edge efficiency.

From its original founding in 1986, the Neyret Group has grown to encompass 200 employees in two production sites: Société Guy Neyret producing indexed machines in Chaponost, near Lyon, and LAGNIEL producing continuous motion machines in Douvres-la-Délivrande in Normandy, near Caen.

Working together, these two arms of the group design and develop fully customized “turnkey” assembly solutions for clients around the world, and for many different areas of application.

Design for assembly

Neyret Group’s guiding design philosophy is that the end-product defines process and therefore the ideal customize machine solution.

Indexed Motion  Machines

Cam-driven indexed motion Neyret assembly machines deploy an almost infinitely variable range of manipulators and testing processes around an in house manufactured turning ring. These are inherently more suited to high precision processes that also need to be varied between batches. This is because manipulators that work from the inside to the outside of the machine provide a very high level of accessibility to operators and maintenance personnel for any type of intervention.  For even greater ergonomics, Neyret Group has designed an ingenious housing opening system to provide 360° access.  Satellite platforms are also designed to be easy-access.

Société Guy Neyret indexed motion machines can be adapted to any sector or industry, and for all types of component geometry, from the simplest to the most complex. SGN rotary assembly machines are designed and configured according to clients’ individual products and specific needs and requirements.

This versatility is underpinned by a range of more than 120 types of specific manipulators either mechanically or servo driven, with each machine able to accommodate up to 36 manipulation or process stations on a 1.44 meter diameter rotating platform.  Each process ‘nest’ can easily be changed simply with a quarter turn and lifting out, ensuring never-ending flexibility.

The range of processes that can be accommodated includes laser, ultrasonic or thermal welding,  vision and dimension checks, flow or pressure tests, various types of printing, gluing, riveting, screwing, labelling, greasing, oiling, and silicon application processes.

High-Speed continuous motion machines

LAGNIEL’s high speed continuous motion and kinematic assembly machines allow longer individual process times while maintaining high rate production. This is a fully mechanical system that guarantee high precision and repeatability, attributes particularly for medical devices and delivery systems.

This technology is particularly suitable for manufacturers of disposable consumer products (perfume and lotion pumps, actuators, aerosol valves, trigger sprayer, pens, batteries), manufacturers of medical consumables (safety syringes, lancets, IV sets, auto-injectors, etc.), and manufacturers of other high-volume products (all sorts of caps and closures, irrigation drippers, etc).

These high-speed automated machines are capable of performing multiple tasks simultaneously while retaining control over the whole process at all times, with components introduced continuously.

Output can reach 1200 parts per minute depending on the complexity of product and process.

Again, continuous motion assembly can include a huge range of process operations such as crimping, clipping, gluing, ultrasonic welding, laser and inkjet printing, labelling, siliconizing as well as checking tests such as presence, orientation, height, flow and pressure tests measures, and all sorts of vision inspection. LAGNIEL is the only manufacturer in the world able to perform ultrasonic welding in continuous motion.

Further advantages are inherently smaller size and footprint for any given output, suiting clean room operations, and limited number of different moving parts reducing maintenance and spare parts demands.
