HECKL Testing Facility

In addition to delivery of products within the framework of its production activities, the HECKL Company also provides services. What kinds of services? In particular, we utilise our exquisitely equipped testing facility to test our own products, but we would like to enable third parties to make use of it. Here we will explain what equipment we have and what kinds of tests we are able to carry out.

Liebisch S 1000MTR Salt-Spray Chamber

The fine salt fog is delivered in the chamber, condensing on the test samples, initiating corrosion and material ageing. There are two decks to cope with a large quantity of samples. Up to 100 kg of samples can be placed in the chamber, whose inner volume is 1,000 litres.
The tests of the corrosion endurance are carried out in compliance with our internal regulations and Czech and European Technical Standards (ČSN EN ISO 9227 – NSS, DIN EN ISO 6270-2, ASTM B 368, etc.).
In general, an exposure of 100 hours in the chamber corresponds to 10 years, and 1,000 hours to 50 years in the usual outdoor environment.

Q4 Tasman Spectrometer

This equipment can identify the composition of metallic alloys containing iron and copper and analyse cast articles made of such alloys. The evaluation software creates reports that can be printed and/or sent by e-mail.

DIO 1000 Ultrasound Defectoscope

This instrument detects mechanical failures in cast articles. It complies with the testing conditions provided by the ČSN EN 12 608-1 Standard.

Paint inspections

This equipment is used to test mechanical properties of paint layers:

• measuring paint layer thickness with a separate probe (our measurements are between 0 and 1,500 µm, but a larger range can be set)
• includes sets for carrying out chipping tests according to the ISO DIN 2409 Standard
• equipment to carry out „pull off tests“ according to the BS EN 24 624 and ISO 4624 Standards
• equipment for impact resistance tests according to the ASTM 2794 Standard to check the adhesion, brittleness and elasticity of paint layers – tests by falling weights

3D scanner

This equipment is used for checking geometrical dimensions. These measurements are taken along three axes, with an accuracy of at least 0.8 to 0.1 mm according to the DE VDI/VDE2634 Standard. The system makes use of two cameras on a position-setting stand and a rotating table with a load bearing capacity of 100 kg. Reverse-engineering software creates a 3D model from the collected data.

Torsion-measuring stand

This stand enables us to test the torsion stress of metal profiles and rods. We use this equipment to test gate valve sets.

 Pressure-measuring stand

This stand is used to test the press load. In the HECKL Company, it is used to test cast-iron and plastic covers.

Capillary plastometer

This equipment measures the melt flow index (MFI). It is a standardised testing method based on measuring the quantity (weight or volume) of melted material going through the testing nozzle in 10 minutes under controlled conditions. The MFI value is determined for plastic materials.

UV chamber

In this chamber, samples are exposed to UV radiation to simulate aging. In general, 100 hours in the chamber corresponds to 10 years, and 1,000 hours to 50 years in the usual outdoor environment.

Memmerth heating and drying oven

This equipment tests endurance of samples with respect to heat. It makes it possible to expose the samples to high temperatures between 20 °C and 300 °C and/or carry out the so-called cyclic temperature tests.

Binder climatic chamber

This chamber enables us to carry out exact heating and cooling tests of industrial materials, as well as ageing and stress tests. Its temperature range is from -40 °C to +180 °C (without humidity), and from +10 °C to +95 °C (with humidity)

Rigaku handheld spectrometer

This instrument is based on Raman ResQ CQL. In a few minutes it will provide information about an unknown substance (with 1,200 substances in the library).

Sample melting press

It carries out a quick visual detection of unwanted admixtures in purchased or processed plastic re-granulated materials, fibres, chippings and other remainders from the production of plastics.

Aquatrac 3E

Water content measuring in polymeric materials and plastic granulates; possibly also samples taken from finished components.
