Felt Tip Pen Application

HEITEC Hot Runner Systems of Burgwald Germany, represented by Technoject Machinery in North America,  impresses again with innovative solutions for the production of a felt tip pen with side injection. 

A professional system for side gating was required for the modern production of a felt tip pen. The barrel made of PP needs to guarantee a long life of the pen. The writing pen is, of course, a proprietary development by STAEDTLER.

The felt tip pen as a finished product can be used in various versions for writing on white boards or flip charts.

The required product quality dictated a double-sided injection per article in order to ensure the desired precision and dimensional stability.

The computer simulation carried out at Heitec confirmed once again the planned course of action.

New X-Slim Line

Heitec Hot Runner Systems, available in North America from Technoject Machinery Corp, has made a name for itself as a leader in developing innovative products for the injection moulding industry. Heitec was the first supplier to introduce the Slim-Line nozzle for inside gating of cosmetic caps in 1992. With the recent introduction of the new “X-Slim” Hot Runner Nozzle one will be able to process larger shot weights with relatively small installation bores. This new nozzle design has the largest flow channel diameter to installation bore diameter ratio on the market. For example type 01.059.11 comes with a 4.5 mm flow channel diameter, but only requires a 11 mm installation bore diameter. Installation bore types range from 11 to 20 mm diameter. The benefits of this new series are wide ranging from being able to process larger parts with less installation room to allowing more flexibility in choosing the best gate location. This nozzle series is available as a hot tip or as a valve gate version. Lengths can be chosen from 50 to 300 mm.
