For selection of gate diameter it is important to take into consideration the material flow characteristics, share rate of resin, molding conditions, fill time requirements, gate vestige, wall thickness and configuration of parts to be molded. Situations requiring high injection velocities must be considered when selecting small gate diameters. High injection rates may require larger gates due to shear heat build up (e.g. high weight thin wall applications). See material manufacturer s literature for further information regarding material to be molded. To compensate for nozzle s growth when heat is applied, the linear expansion of the nozzle (BE) at a given temperature must be added to the nominal dimension. The formula below shows how to figure boring depth (dimension + BE). The tip of the nozzle will now be flush with the cavity line at processing temperature. Formula for determining this expansion factor is as follows: BE = dimension x x nozzle set point - 68ºF (assuming the mold is at 68ºF during operation). If mold temperature is different, substitute 68ºF with actual mold temperature. EXMPLE: Given a 4.34 inch dimension, with a set point of 500ºF: BE = 4.34 x x (500-68) = 0.0 Thus + BE will be 4.45 Note: The above information is only given as an example; variations may occur based on mold configurations and cooling factor.

10 Gate-Mate Hot Sprue Bushings 6 Gate-Mate pplications and Benefits DME Gate-Mate Hot Sprue Bushings The DME Gate-Mate Hot Sprue Bushing is designed for direct part gating in single-cavity molds, eliminating the conventional cold sprue. The unique design of the bushing provides minimal gate vestige, without the objectionable witness lines so commonly found on direct gated parts. The bushing transfers molten plastics from the machine nozzle to the mold cavity via a direct channel in the body. The plated copper alloy tip provides an improved temperature profile in the gate area. The DME Gate-Mate Hot Sprue Bushing utilizes an advanced design square coil heater and independent thermocouple, strategically located for precise temperature control. The bushing is available in three sizes to suit a variety of applications. See the DME Control Systems Catalog for Smart Series Single Zone Temperature Controllers.

Material in the channel is heated by a special helical tubular heater which surrounds the melt stream. This heater distributes heat uniformly throughout the bushing and is virtually impervious to moisture, gases and plastics contamination. The helical tubular heater (20 or 240 volt) is thermocouple equipped so temperature can be closely controlled using a DME single-zone Closed Loop Temperature Controller. The standard S-Series Straight-Shot is designed for direct part gating or for feeding half-round or trapezoidal runners. It is supplied with a.6 diameter gate and no gate land. vailable in seven standard shoulder lengths with either a 2" or 3 4" spherical radius and 20 or 240 volt heater.
