• Description: 1. Mechanical reasons, such as overheating of the barrel due to abnormal conditions, injection of resin into the product after pyrolysis, burns, or viscous flow of resin from internal nozzles and simple internal threads, check valves and other components, which decompose into products with dark brown burn marks. Solution: Clean nozzles, screws, and barrels. 2. The reason for the Table Mould(FURNITUREMOULD) https://www.furnituremould.com/product/chair-table-stool-mould/ is mainly due to the exhaust of the table mould. This kind of burn usually occurs in a fixed place and is easily distinguished from the first one. Solution: Take anti-exhaust measures. 3. In terms of shape, when the back pressure exceeds 300MPa, it may overheat the cylinder and cause burns. Screw speed is too high, overheating, generally within the scope of 40-90R/min. Solution: When the table mould does not have a small exhaust port or exhaust pipe, the injection speed is too high, which can lead to the burning of superheated gas, thus reducing the speed of the table mould.
