Progress in Micro Injection Molding Technology

Battenfeld/Battenfeld exhibited "Microsystem 50". This device is specially designed for processing high-precision medical parts that are lighter than 0.01 grams. The live demonstration students produced a vascular cartridge with a diameter of about 4 mm and a wall thickness of about 0.4 mm.

Nissei's exhibits are only 51 tons of mold clamping force, and the model is the Elject EP5 true miniature all-electric injection machine with an injection volume of less than 3 grams.

The company B0y stated that it made people realize what was the “minimum injection” at the K show. The Boy 12A injection molding machine with a clamping force of 15 tons produced weight in a two-cavity mold; only 0.001 g. Micro gears. In this straight: 12 mm diameter plasticizing device. The melt 1 material gives a shorter residence time and better thermal stability.

Other new micro-injectors are the new "Allrounder U" series of hydraulic injection machines from Aberger/Arburg in Germany. The newest model in this series with a clamping force of 38.5 tons was previously only 13.5 to 20 tons. It features a removable, rotatable injection device for the production of connector parts.
