Detailed Description

large duplicaton for complex picture,the hardness can be adjust as your requirement. the product should be in high pure and good elasticity and good Tensile strength ,tear strength 1 Wash and clean molds with detergents，dry the molds and use an air gun if necessary，and apply a film of mold release． 2 Determine the normal proportion of pad printing silicon and silicon oil on the basis of customer requirements．Add more silicon oil if a larger area of printed pattern and therefore soft rubber head is needed by the customer.0therwise,add less or no silicon oil for better hardness.For normal pad printing rubber head, hardness between 15A°-25A°will be appropriate．If excessive amount of silicon oil is added，the number of printing will be limited by an extremely soft rubber head，and the molecular weigtht of silicon of however supreme quality will be destboyed by silicon oil,and therefore，the phenomenon of compromised resistance to abrasion，solvent and aging. 3 The normal proportion is as follows：100g silicon admixed with 30g silicon oil for a hardness of 20A°will be suitable for pad printing for alloy toy cars and products with small patterns and contact area．If larger pressure contact surface or soft rubber head is required，the silicon and silicon oil proportion can be adjusted to 100：30，100：50 and so on．Remember，the more silicon oil is added，the softer the rubber head will be，and the number of pad printing，resistance to abrasion and solvent will be undermined，and hence，heightened cost and more material waste．
