Valve-gate systems
The nozzle types listed in this chapter cover a wide range of uses. The modular nozzle design allows a rapid replacement of components when required. The two-component shaft (patented) with varying design features assures excellent insulation in the front area of the shaft and the least possible loss of heat between the hot runner nozzle and the cavity.
Where requirements are high in terms of appearance, reduced cycle times, minimum shear stress and large gate cross-sections, valve-gate technology provides the solution.
The single nozzles are operated pneumatically (max. of 8 bar). The connections are mounted externally. Standardized modules reach linear measures of 40mm to 250mm at a material pipe diameter of 3,8mm to 12 mm,dependent on nozzle type. Up to 30% glass fibre filled plastic can be processed.
Replaceable Valve Pin Guides
The new innovative design of the contouring needle guide and the optimised valve-gate needle allow non-contact and low-wear gate closing. The PM needle guide made of metallurgical powder steel ensures economical and virtually wear-free operation. While closing, the needle is first centered through a tapered guide until it lowers precisely into the cylindrical guide. Another advantage is the separation of needle guide and material tube, which means that any necessary change of needle guide is a simple procedure. Gate diameters of 1.0 mm to 4.0 mm are selectable.
Type LA
The needle is centred by means of a conical guide, until it fully and precisely enters the cylindrical guide (to the axis of the gate bore).
Advantages:
Long service life, since virtually no wear
Replaceable needle guide
Needle guide immerses to the article and is contour-shaping
Recommended for wearing materials
By exchange of the PM pieces, the optimized shut-off needle can enlarge or reduce the gate ? without reworking the mould nest. The exact needle guide achieves a virtually wear-free seal and a clean gate without burrs.
Tightest tolerance between the needle guide and the gate.
DIN EN ISO 9001:2008 certification.
