- The cooling channels located as close to the mold surface as possible, but should pay attention to the mechanical strength of the mold material.? - Diameter cooling channels must be greater than 8 mm (8 or 10) for ease of processing and must remain so to avoid the flow rate of the liquid is cooled by different cooling diameter other channels nhau.?- cooling system should be divided into multiple zones cooled cooling channels to avoid too long leads to large temperature difference.? - pay special attention to the cooling of the thickest part of the product.? - thermal conductivity of the mold material is also very important.? - Note to the phenomenon of warping due different shrinkage when different thickness products. ?
