Aluminum alloy die casting material application, strength, mass production overview
Features of aluminum alloy materials
Lightweight, excellent strength, high-precision processing, flexible design, good thermal conductivity, low maintenance cost, high production efficiency, environmentally friendly and recyclable
Strength design
The boss here is not the boss, but the ribs
Rib design has a vital impact on product strength
Improve structural rigidity
The rib design can increase the local rigidity of the product, making the thin-walled structure less likely to deform due to external forces.
Prevent deformation and warping
The design stress evenly disperses the internal shrinkage to reduce the warping problem and maintain the shape stability of the product.
Enhance the load-bearing capacity
The presence of ribs can make the stress more evenly distributed throughout the structure, reducing the risk of local damage.
Save material costs
Reasonable rib design height and thickness can reduce material consumption, reduce manufacturing costs, and make the product lighter.
Prolong product life
In applications under dynamic loads, ribs can delay the generation and expansion of cracks and increase the service life of the product.
Rib design not only affects the strength and performance of the product, but also has a profound impact on the stability and cost-effectiveness of the die-casting process.
Therefore, the size, shape and position of the ribs should be carefully considered in the design of die-casting molds to ensure the functionality and reliability of the product.
Tolerance
Dimensional tolerance: the allowable deviation range in terms of length, width, height and other dimensions.
Shape tolerance: refers to the allowable deviation in the shape of the product, such as flatness, straightness, roundness and other appearance and functions.
Surface smoothness tolerance: the surface smoothness of the product meets the required standards.
Material performance tolerance: such as tolerance requirements in terms of hardness, strength, etc., to ensure the safety and durability of the product.
QC inspection
Functional test: perform action test to confirm that the mechanism operates smoothly, without abnormal sound or stuck.
Fit check: especially for airtight and watertight parts to check for air leakage and water leakage.
Reconfirm the size and position: check whether the key installation dimensions, verticality and concentricity meet the standards.
Record and traceability: make inspection reports to facilitate subsequent quality tracking and analysis.
Reasonable tolerance requirements are to ensure that the product size meets the design requirements and has stable quality and performance.
Precision machining
After die casting, multiple subsequent processing and inspection steps are still required, including deburring, finishing, surface treatment and quality inspection.
Deburring: After die casting, due to the mold parting line, there may be some extra burrs on the finished product to remove.
CNC finishing: to achieve precise size or shape requirements. For example, drilling, tapping, or flattening.
Surface treatment: film or electroplating, painting, polishing or powder coating.
Assembly precautions
Fitting accuracy: confirm the fitting tolerance to avoid too loose or too tight.
Sequence and method: assemble in the correct order.
Force control: use equipment such as torque wrenches to ensure that the bolts and nuts are evenly force and within the specified range.
Lubrication and protection: add lubricating oil or grease when necessary to ensure smooth operation and prevent wear.
