A method for coaxially extruding an extrusion product, comprising - providing an extrusion device, having - a pickup ; - a first pickup bore , which is formed in the pickup and in which a first extrusion ram is arranged; - a second pickup bore , which is formed in the pickup inside of the first pickup bore and coaxially thereto, and in which a second extrusion ram is arranged; and - a die with a mold cavity , which is connected with the first and second pickup bore ; - arranging a first material bolt made out of a first material in the first pickup bore ; - arranging a second material bolt made out of a second material in the second pickup bore ; and - extruding an extrusion product , in which the first and the second materials are positively and materially connected, comprising: - advancing the first extrusion ram in the first pickup bore , such that the first material is resultantly pressed into the mold cavity of the die , and herein reshaped; - advancing the second extrusion ram in the second pickup bore , such that the second material is resultantly pressed into the mold cavity of the die , and herein reshaped, wherein the second extrusion ram is displaced coaxially to the first extrusion ram ; and - materially and positively connecting the first and the second material to an extrusion product in the die , such that the first material envelops the second material in the extrusion product . - providing an extrusion device, having - a pickup ; - a first pickup bore , which is formed in the pickup and in which a first extrusion ram is arranged; - a second pickup bore , which is formed in the pickup inside of the first pickup bore and coaxially thereto, and in which a second extrusion ram is arranged; and - a die with a mold cavity , which is connected with the first and second pickup bore ; - a pickup ; - a first pickup bore , which is formed in the pickup and in which a first extrusion ram is arranged; - a second pickup bore , which is formed in the pickup inside of the first pickup bore and coaxially thereto, and in which a second extrusion ram is arranged; and - a die with a mold cavity , which is connected with the first and second pickup bore ; - arranging a first material bolt made out of a first material in the first pickup bore ; - arranging a second material bolt made out of a second material in the second pickup bore ; and - extruding an extrusion product , in which the first and the second materials are positively and materially connected, comprising: - advancing the first extrusion ram in the first pickup bore , such that the first material is resultantly pressed into the mold cavity of the die , and herein reshaped; - advancing the second extrusion ram in the second pickup bore , such that the second material is resultantly pressed into the mold cavity of the die , and herein reshaped, wherein the second extrusion ram is displaced coaxially to the first extrusion ram ; and - materially and positively connecting the first and the second material to an extrusion product in the die , such that the first material envelops the second material in the extrusion product . - advancing the first extrusion ram in the first pickup bore , such that the first material is resultantly pressed into the mold cavity of the die , and herein reshaped; - advancing the second extrusion ram in the second pickup bore , such that the second material is resultantly pressed into the mold cavity of the die , and herein reshaped, wherein the second extrusion ram is displaced coaxially to the first extrusion ram ; and - materially and positively connecting the first and the second material to an extrusion product in the die , such that the first material envelops the second material in the extrusion product . <EOS>
