ProLine Testing Machine from ZwickRoell

ProLine is the ideal testing machine for function tests on components and standard tests on materials. Used in conjunction with our intuitive Zwick Roell testing software, ProLine materials testing machines offer fast, easy operation. All test programs can be used.

Development and manufacture of ProLine, including all mechanical, electronic and software components, together with the comprehensive range of accessories, takes place at Zwick's production facility in Germany, enabling optimum matching of all items.

Key Advantages and Features

Integrated Safety in Accordance with the EC Machinery Directive

The statutory safety requirements of the EC Machinery Directive are implemented in all Zwick machines, while an EC Declaration of Conformity accompanies every machine. The most state-of-the-art safety technology and proven industrial components that comply with the highest safety and industrial standards (IEC 60947 etc.) are used. The highest degree of safety for user and testing system is guaranteed.

High Stiffness and Precise Crosshead Guidance

Two steel columns provide highly accurate guidance for ProLine's moving crosshead. The stiff load-frame profile and generous connecting surfaces reduce the inclination angle of the crosshead under load, enabling very precise alignment and application of force to the specimen. This is advantageous for flexure tests, compression tests, precision tests on components etc.

Powerful Drives

  • Extremely low minimum speeds can be set, combined with high speed-stability. The drive also delivers high crosshead-travel resolution. This is important in cases such as component tests with especially demanding travel-precision requirements, or tests on specimens with high stiffness and short travel.
  • 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.
  • Faster return speeds mean reduced cycle times and increased test throughput. The motor employs zero-maintenance AC technology.

Safety for the Entire Testing System

The two-channel safety circuit, including Emergency STOP, crosshead limit stop switch and interlinked accessories, Drive OFF switch and motor brake function, together with the operation mode switch, ensure enhanced safety during setup. The CE-compliant electrically interlocked safety device prevents interference with the machine during the test.

Description of Application

By targeting ProLine specifically at standardized tests on materials and components it has been possible to achieve particularly simple, compact operation for these testing machines.

Standardized tests on components are many and varied. Examples include testing plug and spring contacts in the electrical industry, checking joining and pressing procedures on precision engineered components and ring-stiffness tests on reel-cores and pipe sections.

In the packaging and food industries there are stackability tests on plastic containers and cardboard boxes, open-and-close tests on snap-on lids, pull-off tests on can lids, tear-growth and adhesion tests on plastic films and hoses and pull-off tests on carrying-handles.

Technical overview

  • ProLine is available with test speeds from 0.0005 to 1500 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.
  • ProLine is available for test loads up to 100 kN and with test area heights from 1050 mm to 1450 mm.
  • ProLine can be operated with standard commercial PCs or laptops and requires no special expansion card.
