The shunt materials and extend the cooling
In order to produce the molten material fill the cavity at equal speed, the arrangement with the runners on the mold needs to be symmetrical and equidistantly distributed. The surface of the runner have to be polished to reduce the flow resistance to offer a faster filling rate.

It truly is the channel connecting the primary channel and each cavity from the multi-slot die.

If an equal volume of flow is used, the flow path resistance having a circular cross section is lessen. The contour and size of the athlete section affect the flow from the plastic melt, the release from the product and the ease regarding mold making.

Therefore, trapezoidal or semi-circular cross-flow runners will often be used, and they are opened on half in the molds with a stripper fishing rod. In obtain to facilitate demoulding, the bottom is often borne by the stripper.The cold material hole is known for a diameter of about 8-10mm and a depth of 6mm. However, due to the small specific surface of the cylindrical flow penetration, it is unfavorable for the cooling of the diversion channel material, and this diversion passage have to be opened on the two form halves, which is labor-consuming and also difficult to align. For most thermoplastics, the cross-sectional width of the runner is not more than 8m, especially large 10-12m, specifically small 2-3m. The most notable of the stripping rod needs to be designed as a zigzag connect or a depressed groove so the strip can be smoothly pulled out during demoulding. The size of the runner depends on the sort of plastic, the size and thickness in the product.. To meet the needs in the premise should be reduced cross-sectional area if you can , to increase the shunt materials and extend the cooling time period
