The precision range of Laptop mould: 0.02mm!

Laptop mould is an important factor affecting laptop prices. In simple terms, the mould is the injection mould, stamping mould, etc. used to produce the shell, from the aspect of the appearance design and the selected materials.
As for the selected materials of the mould, engineering plastics, magnesium-aluminum alloys (often referred to as magnesium alloys in shopping guides to appear noble) and carbon fiber materials are used. Generally speaking, the actual value of engineering plastics is relatively low, and it is also the most used material for some low-cost books; aluminum-magnesium alloy is higher than ABS engineering plastics, and the actual value is relatively high, and the weight is relatively light. It also helps the heat dissipation of notebooks. Therefore, it is the most popular material used in mainstream notebooks; carbon fiber material has the hardness of magnesium-aluminum and the relatively strong plasticity of engineering plastics. The price is higher than that of magnesium-aluminum alloy. It is generally used in relatively high-end products.

◆ Processing time: 7 hours and 9 minutes

Machining with super-hard tools effectively controls the wear of the tool, and even the multiple processing of small shapes can be processed with stable accuracy, shape and roughness.

Precision of the machined surface

◆ Spindle: Effectively avoid thermal deformation, high rigidity, low vibration
◆ Frame: High rigidity structure, low vibration of moving surface, damping capacity
◆ Feed shaft: High rigidity, low vibration
