cLine - first choice for testing automotive seats

cLine materials testing machines are ideal for component testing and for testing flexible foam materials. 

Component testing mainly involves molded foam products such as mattresses and vehicle seats and upholstery; for materials testing, cubes or slabs of flexible foam are used. Compression tests, cyclic indentation tests and pulsating compressive strength tests (alternating load tests) are employed. Used in conjunction with our intuitive  ZwickRoell testing software, cLine materials testing machines are very easy to operate; this range features a test area which is open on three sides.

Description of application

The cLine product group features a test area which is open on three sides.

cLine materials testing machines are ideal for component testing and for testing flexible foam materials. Component testing mainly involves flexible foam products such as mattresses and vehicle seats and upholstery. For materials testing, cubes or slabs of flexible foam are used. Compression tests, cyclic indentation tests and pulsating compressive strength tests (alternating load tests) are employed.

Key advantages and features

Ergonomic operation

Improved ergonomics due to side operation, swiveling table extensions on both sides, an additional single-sided table extension and an optional display-equipped remote control for set-up and operating modes.

Standard-compliant positioning accuracy

Standard-compliant positioning accuracy is reliably achieved. The corrected targets are approached using online correction performed automatically in the testXpert III testing software and the testControl II machine electronics. For the user this means greater accuracy in displacement measurement at specified loads.

Powerful drives

Extremely low minimum speeds can be set with simultaneous high speed-stability. while the zero-backlash ball-screw shaft delivers high crosshead travel resolution. The motor employs zero-maintenance AC technology.

The high test-speed range can be used without restriction. Faster return speeds mean reduced cycle times and increased test throughput.

Stiff, robust machine frame

The robust and stiff design of the C-shaped load frame enables high accuracy when measuring the deformation of flexible specimens. This allows the use of additional sensors to be avoided for many applications with the cLine.

Compression die tools

Compression dies are available in different diameters according to the requirements of standards of company specifications. Compression dies are circular flat, hemispherical or spherical. They are easy to install and change.

Integration into production process

cLine materials testing machines can optionally be integrated into the production process, for example by means of roller conveyors in front of and behind the support table.

Safety for the entire testing system

The highest level of safety is achieved with the two-channel safety circuit. It includes the crosshead limit switch, the drive-Off switch, motor break function and the operation mode switch. Relevant accessories are also integrated into the safety circuit. The CE-compliant safety device with electrical interlocking and mechanical guard locking prevents interference with the machine during the test.

ZwickRoell Engineering—Made in Germany

The development and manufacture of materials testing machines, including all mechanical, electronic and software components, together with our comprehensive range of accessories, takes place at ZwickRoell's production facility in Germany, enabling us to create a product that is perfectly harmonized. Each materials testing machine is made of the highest quality standard enabling ZwickRoell to offer the best possible support.

cLine materials testing machines are especially suitable for component testing and for testing flexible foam materials.

Technical overview

General

  • cLine is available with test speeds from 0.0005 to 1000 mm/min, depending on type. Testing machine speed is independent of the test load.
  • The high test-speed range can be used without restriction. In addition, test loads up to 110% of machine nominal load are permissible to compensate for heavy combinations of test fixtures, accessories etc.
  • cLine is available for test loads up to 10 kN and with a test-area height of 819 mm.
  • cLine can be operated with standard commercial PCs or laptops and requires no special expansion cards.
