Troubles mean the generation of defective products in the compression moulding. The generation of defective products is considered to result from the flow and the scorch characteristics of mixed compound. These characteristics are dependent on processing temperatures. Watching the flow state when mixed compound goes into mould cavities is important. Other causes, such as parallel accuracy and distribution of temperature of platens, staining of mould, are related to defective products. This paper considers the causes and measures against defective products.
