Method for manufacturing bimetallic seamless plastic insert casting piece

Abstract

The invention provides a method for manufacturing a bimetallic seamless plastic insert casting piece. The method comprises following steps: A. prefabricating a metal piece to be die-casted according to demands; B. placing the prefabricated metal piece to be die-casted into the cavity of a die-casting die, closing the die, pouring liquid metal of a melting state into the die, and obtaining a seamless bimetallic casting through a die-casting molding manner; C. removing burrs of the bimetallic casting; D. machining the bimetallic casting whose burrs are removed; E. performing anodic oxidation or other surface treatments on the machined bimetallic casting; and F. performing other surface decoration treatments on the bimetallic casting after the bimetallic casting is subjected to anodic oxidation or other surface treatments. By employing the method for manufacturing the bimetallic seamless plastic insert casting work piece, manpower and material resources can be saved, the efficiency is high, the productivity is high, the cost is low, and needed shapes and structures can be manufactured on the metal piece to be die-casted, so that machining is not needed or less needed. The method is suitable for manufacturing shells of mobile phones, flat computers, notebook computers and cameras.

Description

technical field [0001] The invention relates to the technical field of die casting, in particular to a production method of a bimetal seamless embedded casting workpiece. Background technique [0002] At present, the existing production method of metal casings for high-end mobile phones, tablet computers, notebook computers, and cameras is as follows: the metal (aluminum alloy, stainless steel, titanium alloy) blank is formed into a preliminary shape by multiple times of forging and then mechanically processed into a finished product. Or use sheet metal to directly machine into finished products. The machining process requires a lot of cumbersome processing by CNC. The processing process wastes a lot of human and material resources, low efficiency, low production capacity and high cost, which cannot meet the huge market demand. [0003] Now there is an urgent need for a production method of bimetal seamless embedded casting workpieces to solve the above problems. Contents...
