Polishing is essentially the removal of metal by the action of free abrasive grains carried to the work piece by a tool.Here is several reasons for plastic mold polishing are liseted below:
1)Plastic mold polishing may achieve special optical properties in a product,will enlight beams pass through the produt wall(compact disc,mirrors,etc),any major unevenness or waviness will distort the light and result in poor performance of the product.
2)Plastic mold polishing may enhance the appearance of the product,This is the most common requirement in plastic mold.It should be noted,however,that th appearance often is required for the visible outside only.Often,no polish is required on the seen inside of the product,and the finish there need not be better than that required for easy ejection of the product from the mold.For clear plastic products where the inside finish as the outside of the product.
3)Plastic mold polishing may faciliate ejection.This applies generally produced by deep recesses in the cavity or where there is little draft angle specified,the cavity must also be free of roughness that may prevent easy ejection.
4)Plastic mold polish may prevent stress risers in a product.Any sharp indent or corner in hardened mold steel,usually created during grinding,will increase the rish of breakage caused by stress concentration.Such corners must be polished to remove the sharp”gouges”.

1.Mould shall run fall automatic cycle.
2.Identify all eyebolt holes thread size,using metric system.
3.Mould must be lubricated and rust protected.
4.Eliminate fluid cooling,and spray the mould with a rust inhibiting mould spray.
5.All water inlets and our lets shall be stamped and indentified in mould-base.
6.Use two tie straps per side of mold.to ensure that shift does not occur along the skid and within the crate.
7.Wrap the mould with a polybag wrap to completely cover the mould.
8.Mould shall be provided with two safety straps,intalled across parting line to ensure mould doesn’t open during shipment,installation or removal.
