Fields of application

Pantecnica group and the GMT group are leaders in vibrationisolation technology providing state of the art solutions and relevantapplication know-how to meet the requirements of designers,builders and managers of rail and road public transport.

In the field of "transport" the primary objective is to improve thesafety and comfort of rail vehicles.

To this end, several products have already been successfully appliedby manufacturers and users of rolling stock all over the world: fromprimary suspension systems to complete assembled lines.

Production and test facilities

We use the latest up-to-date equipment in

•development/construction department•all manufacturing stages•laboratory•test and experimental departments•metrology

and we are fully qualified to advice our customers on noise and vibration insulation problems and provide optimum solutions.


Production facilities

GMT-Products are manufactured by modern injection moulding and transfer and compression machines.


Test Laboratories


1. Development, construction and design

on the basis of

• FEM-calculation

• FKM-method


2. Damage Calculation

Is Performed to

▪ predict lifetime of one or multi axial loaded rubber-to-metal-bonded parts

▪ shorten dynamic component test

▪ eliminate non-damaging load rates from load collective

▪ calculate load collective with very high cycles-to-failure which cannot be tested within a reasonable period of time

This kind of calculation serves as prediction and has to becombined fundamentally with a shortened component test forverification.


3. Tool design and tool manufacture

CM-Tool

TM-Tool

IM-Tool


4. R&D and test process

Testing capabilities:

•Static and dynamic 1D, 2D, 3D and 4D testing of characteristics and properties

•Endurance and lifecycle tests, even with real (measured) load collectives

for development, optimization, qualification andquality assurance of:

•GMT Air spring bellows and –systems

•GMT Rubber-Metal-Elements
