GUILIN, China—Guilin Rubber Machinery (GRM) has developed and manufactured an "innovative" double extrusion and calendering semi-steel lining extrusion line, according to parent company ChemChina.
The equipment is especially suitable for the production of semi-finished parts such as inner liner, thin rubber and seam allowance rubber of high performance tires, ChemChina said in a recent statement.
The line has an "intelligent closed-loop distance adjustment function" in the extrusion and calendering section, enabling it to carry out automatic distance adjustment to ensure uniform rubber thickness.
The equipment has an automatic and intelligence adjustment feature for rubber gumming, allowing the inner liner rubber to be cold or hot gummed, ChemChina added.
The machine offers "high gumming precision, good compactness, uniform thickness and good plasticizing effect," the company said.
The features improve the production efficiency of the equipment and reduce the cost of products.
