Zinc Alloy Die Casting of Knob have a good surface roughness, strength and elongation, Which are widely used in a variety of ornaments, such as furniture, accessories, door handle ,architectural decoration, bathroom accessories, lighting parts, toys, tie clips, belt buckles, various metal buckle and so on,they are required a good surface treatment performance.

Zinc Alloy Die Casting of Knob have their own purposes, need to meet the performance requirements.
(1) mechanical properties, tensile strength, when the material fracture resistance;Elongation, brittleness and plasticity of the measure;Hardness is the resistance of the material surface is pressed into a hard object or friction caused by plastic deformation.
(2) state of the working environment: temperature, humidity, media contact with the workpiece and air tightness requirements.
(3) precision: accuracy and dimensional stability can be achieved.
