Precision 'D' Series Bushings | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

The Precision 'D' series pinpoint bushes are simple to install and use and are ideal for applications where gating directly on to a part with a minimal gate vestige is essential, The pinpoint tip coil heater and thermocouple are easily replaceable in the press for easy installation and maintenance. The flow of material is internal and direct. The pinpoint bushings heat is external and is generated by a rectangular coil heater (230V ac). A stainless steel cover holds the coil heater in contact with the body of the bushing, ensuring good heat distribution. A thermocouple is located close to the flow channel thus permitting tight control of the temperature of the material. The pinpoint gate diameters range from .7mm to 1.5mm (.027" to 0.060") giving a nominal gate vestige of between .2mm and .3mm (.008" to .012"). The pinpoint bushing can be used for all general purpose materials and most engineering grade materials, subject to consultation with the factory. The Precision D Series is available in 4 styles and has a range of accessories available. For the DG/DS series see below, for multi tip click link. |

Precision 'DG' Series - Direct FeedThe Precision DG Direct Feed bush is primarily intended for use singly in direct-feed applications, although it may also be used on multi-drop manifold systems if required. It is available with a choice of 6 different replaceable tip styles, some having wear resistant variants for use with filled polymers. By choosing different tip styles, the bush can be used for pinpoint-gating direct on to the part for a minimal gate scar, or for indirectly gating multiple cavities via a cold runner. Available Lengths & CAD FilesCAD drawings for each of the Precision 'DG' bushings are available for download. Please click on the appropriate link in the table below.

Precision 'DG' Series - Multi-DropThe Multi-Drop version of the Precision DG is identical to the Direct Feed version, except that the heater and thermocouple have redesigned lead exits so that they can be replaced with the tool still in the press, without disturbing the manifold. By using our Bush Extraction Flange, the complete bush assembly can be removed with the tool still in the press.

Precision 'DS' & 'DG' Series - AccessoriesPressure Ring !!MA010021 now replaced with MA010030![]() Pressure rings MA010021* and MA010022 provide extra support under the head to prevent the bushing being pressed into the tool plate from the force of a machine nozzle and / or other pressure. These rings can be supplied by Fast Heat or can be built-in by your Toolmaker, if required. |
