Gate positioning and design for Plastic basket with handles Injection Molds:
Possible locations and effects of gas entrapments created as a result of the filling profile.
After consideration of all the previous points，it must be apparent that the positioning of the gate must be determined relatively early on and before the design build-up has started. If the component is to be conven¬tionally fed, i.e. non-hot runner, the gate location options are further restricted due to the limitations of the two-plate mould design.
Restrictions exist because of the necessity of having to gate on a single plane about the mould split line. When confronted with gating requirements outside the scope of the two-plate design，the mould designer has the choice of selecting either the three-plate or the runnerless mould design formats in order to achieve the desired gate position.
In between the runner and the cavity there is usually a narrow restriction in the runner system and this restriction (where the material enters the cavity) is called the gate. (As the gate size is much smaller than the runner，the plastic basket moulding may be easily separated from the feed system at this point when desired.)
During moulding the plastics material is forced through the sprue, into the runner system and from there into the cavity (or cavities). The plastic basket is formed between the opposing core and cavity, and the surface finish on the component is dictated by the surface finish on these two mould parts.
To ensure that plastic basket production is consistent and uniform the plastic basket mould temperature is controlled, e.g. by circulating water through cooling channels (in the case of thermoplastics) or by means of electrical resistance elements (in the case of thermosets).
