Products Description
Box from the definition of parts function and structural features, with inclusion, support and other structural functions and relatively closed, such as automobile transmission.
(1) The main function of the box
- Accommodate, contain: the functional components of the product will be contained within.
- Positioning, support: to support and determine the position of each component of the product.
- Protection, protection: to prevent the parts and components of the product from being affected by the environment, damage or danger and infringement to the user and operator.
- Decoration and beautification: the main concern of industrial design.
- Others: depending on the function and purpose of the product.
(2) The characteristics of the casting box
- Higher stiffness, strength: casting components are generally larger wall thickness, suitable for higher stiffness and strength requirements of the product shell; can also be made in the casting of some other structural components.
- Modeling adaptability: can make more complex and change the irregular shape.
- Show roughness, low dimensional accuracy.
- Good closure.
- Process flexibility, low cost.
- Other: cast iron material with shock absorption, shock resistance and wear resistance, lubrication performance
(3) Casting box commonly used materials
Cast iron: cast iron mobility is good, body shrinkage and line shrinkage is small, easy to obtain the shape of complex castings, adding a small amount of alloying elements in the casting can improve the wear-resistant properties. Cast iron classification: gray cast iron, ductile iron, creep cast iron, malleable cast iron. Cast carbon steel: cast steel melting point, poor mobility, shrinkage, shock absorption is lower than cast iron, elasticity scale. Aluminum alloy: pure aluminum low strength, hardness, therefore, the manufacture of product shells often use aluminum alloy materials. Commonly used aluminum alloys are: aluminum-silicon alloy, aluminum-copper alloy, aluminum-magnesium alloy, aluminum-zinc alloy.
