The wall thickness control for containers manufactured by the blowing method
The principle of wall thickness control for thermoplastic containers manufactured by the blowing method has been discussed. Typical control systems have been described, in particular designs developed at the OBR (R&D Center) "Metalchem" in Toruń. Economic effects of application of proposed systems have been estimated on the basis of literature data and authors' experience. High recovering rates of capital cost are obtained, in particular for containers of capacity higher than 4 dm3. Therefore, applications of wall thickness control systems should be widespread.
