LEM Technology

Introduction to LEM Technology

Solyem’s static sealing technology also known as LEM technology for gasket, has been invented, patented and produced since the year 2000, and is present within a multitude of combustion engine systems and developed to answer the newest technologies being designed within the E-mobility movement.

Several silicone beads or barriers molded on the top of the gasket along with our topography pattern ensure the seal in-between the two parts to be sealed. Our LEM technology enables excellent sealing function and design simplification of our customers’ parts. In addition, we can supplement our LEM gaskets with other useful functions.

During 100 years of gasket development and more than 20 years of our LEM technology experience, we have developed best practice and a specific design and development process, which we use to ensure sealing results.

Benefits of LEM technology

Compensates variable flange distortions and flatness defects => wide range of application and improved product reliability
Reduces the amount of bolts used for your assembly => weight and cost reductions
Reduces wall thickness on housing systems => weight and cost reductions

Permits high roughness of your housings and covers => machining cost reductions
Compatible with automatic assembly lines => assembly cost and cycle time reductions
Our gasket can be pre-assembled on one of your part and then conveyed to other production stages until final assembly => assembly process ease
Bespoke LEM designs to your distinctive needs

Functions of LEM

Benefits of our LEM gasket technology lies in the optimization of the sealing’s properties and also in the possibility to add other essential functions to our gaskets. For example, we have solved some of our Customers’ issues by designing our gasket with electrical conductivity function.

We are also able to design and produce our gasket integrated to the cover, so that our Customer can manage one part instead of two and optimise its production.

For another project, we offered a gasket with an integrated filtering function of the oil passing through our Customer’s system. This double function is definitely a high added value for our Customer. Moreover, we ensure outstanding quality, figures below speak for themselves.
