In the field of the technician of hot channel, the solutions of closing of unitary needle confront to the user to numerous limitations and are used to to cause problems in the practice.
The separation by fusion produces sewings of union in the pieces of the surface; the range of lengths of filters and diameters is limited; the results of the simple moulds in small series can not transport easily in moulds of series of several cavities, since it changes completely the type of filter; the size of the filters of closing of conventional unitary needle demands big heights of setting and sizes of mould, etc.
The valve of universal needle Z10710 of Hasco solves of easy way many of these problems of hit. The basic principles of the unit of closing of needle are the universality and the modularidad.
The unit of accionamiento of needle, that is available in two standard sizes, can combine with all the filters Techni Shot and Valve Shot of Hasco. Like this it opens to the user a very wide range of types of filters, diameters of channel of mass and lengths of filter of 300 mm maximum, variants of points of injection and guided of needle.
The applications of the technical field with weights and loads very distinct also can llevar of a simple and flexible way, such as it requires in the medical sector and of the packaging.
The structure of the system is extremely compact and also can integrate without problems in small moulds with a height reduced of setting.
An important advantage of the Z10710 consists in that so much the unit, like an individual filter, can employ centred in the half of the mould, or like a unit of accionamiento between the distributor of hot channel and the filter. In this way, the moulds of prototypes or preseries with a type of filter determined can transmit without problems the knowledges purchased to the mould of upper series. Even they can employ the components used from the mould of preserie.
Like this they diminish considerably the costs of the system of hot channel in series.
