Rubber Preformer
The Rubber Preformer (Barwell) is a high-efficiency precision preforming machine designed to prepare accurately weighted and shaped rubber blanks for moulding applications. It processes preheated rubber compounds into controlled-volume preforms, helping reduce material wastage, improve mould filling and achieve consistent product quality.The machine is suitable for a wide range of rubber components, including seals, valves, rubber rings, gaskets, cork products and other precision-moulded components.
