With our own laboratory towards optimised products

Are you afraid that you will not receive the products that will meet the standards‘ requirements?

In cooperation with us, this kind of fear is superfluous.

Our company has its own laboratory, which serves for verifying the adequacy of individual parameters in the in-process and final control. Thus, the possibility of you receiving inadequate products is eliminated.

What kind of equipment is at the disposal of the laboratory?

In order to ensure adequacy, the following devices are at our disposal at the laboratory:

• tensile test machine for tensile tests with an invasive force of up to 1000 KN (100 t),
• an impact tester (Charpy) up to 300 J,
• hardness testers (Brinell, Vickers, Rockwell),
• micro-hardness testers (HVO2…HV10),
• roughness testers,
• magnetic partlice examination equipment,
• equipment for dimension control.

What does the fact that we have our own laboratory mean to you?

1. To you, our own laboratory represents mainly increased control over the properties of the following hidden processes:
   
   
   • The adequacy of the hot forging procedure. Up to the invasive force of 1000 kN (100 t), we are able to test the entire bolt as an element, and not only the machined test tubes, meaning that we can inspect the behaviour of the entire bolt.
     
     
   • The adequacy of the heat-treatment parameters in a larger scope and not only during the final control of products, which, for you, represents greater certainty regarding product adequacy.
   
   
   
2. Great flexibility in the final control of products.
   
   

What do we test at the laboratory?

At the laboratory take place mechanical tests as well as approval tests of fasteners.

1. Testing of fasteners properties

Mechanical properties — the following destructive tests are performed at our own laboratory:

• tensile tests with an invasive force of up to 1000 KN (100 t) at room temperature,
• an impact test according to Charpy at room temperature,
• an impact test according to Charpy at low temperatures.

Mechanical properties — the following destructive tests are performed at accredited external laboratory:

• tensile test at high temperatures,
• tensile test at low temperatures.

Testing of material by non – destructive methods:

• hardness test (Brinell, Vickers, Rockwell),
• magnetic partlice examination,
• penetrants test (surface for fissures),
• ultrasonic examination,
• dimension test,
• roughness test.

2. Approval of fasteners

At the laboratory take place approval tests in cooperation with our own experts and international accredited approval organization; ( TÜV, GL, LR, ABS, DNV, RINA, BV).

Besides that, there is a possibility of certifying the fasteners as well as acquiring the approval tests documentation according to EN 10204, namely: 2.1/2.2, 3.1, 3.2
