Vario TIP FSS – The necessity of cavity sorting

From April 2018 Waldorf Technik introduces itself at the Chinaplas 2018 in Shanghai, China and is focusing on the topic “pipette tips cavity-sorted in racks”. For this purpose, the patented automation system Vario TIP FSS will be presented at the booth of Engel Austria in Hall 5.1H / Booth E71. Producing with 32 cavities. With its slimline design, the system opens up the market to the MedTec injection moulders in new performance classes and keeps the space requirement in the clean room low.


For the first time, a highly integrated production cell for manufacturing pipette tips under cleanroom conditions is presented. This exhibit is the result of cooperation between Europe and China. Engel (Schwertberg, Österreich), Waldorf Technik (Engen, Germany) and Wellmei Mold (Dongguan, China) have combined their know-how and experience with medical precision parts and tailored the system solution exactly to the specific requirements of the Chinese processors.
The automation solution developed by Waldorf Technik removes 32 pipette tips from the mould in sync with the injection moulding process and loads groups of 96 pipette tips, sorted by cavity, into racks. Every 18 seconds, 96 pipette tips are discharged from the production cell, which is enclosed to create a cleanroom environment.
The Vario TIP from Waldorf Technik is the patented and worldwide leading system concept, for example in the production of pipette tips, cuvettes or reagent wells. These products are laboratory consumables that must fulfil high quality requirements and they demand cavity sorting in the packaging unit to guarantee delivery reliability in every case.
Massive reduction of rejects by replacing individual missing parts: In the patented Vario TIP system, individual parts are checked prior to packaging and individual missing parts are replaced by good parts. This way error-related rejects with sporadic errors can be reduced by about 90 % on average compared to conventional devices.
