Zinc Alloy Die Casting Product Analysis
2023-09-12 04:08
1. Knowledge of the product
(1) The use of the product First understand the use conditions of the product. At present, the use of zinc alloy die castings is mainly divided into two categories.
1) Structural purposes: such as automobile carburetors, pillars, door hinges, gears, frames, locks, etc., as structural parts, require high mechanical strength, dimensional accuracy, and internal quality of castings.
2) Decorative purposes: such as daily necessities, toys, decorations, lighting, metal buckles, bathroom accessories, etc. Some die castings are a product, which has higher requirements on the quality of the outer surface of the casting, and requires a smooth surface and beautiful appearance.
When the use and function of the product are determined, a certain brand of zinc alloy can be selected and the corresponding die-casting process can be formulated to meet its quality requirements.
(2) The economic value of the product
To understand the economic value of products, the difference between high-end products and low-end products. High-end products have higher requirements on the performance of die-casting machines and the manufacture of die-casting molds, in order to ensure that the designed products achieve the maximum use effect and the consistency of economic benefits.
(3) Assembly relationship of products
Understand the assembly relationship of the product, what parts need to be matched, how to cooperate, the form of fastening and connection, and select the tolerance that meets the product requirements.
(4) Characteristics of the product manufacturing process
1) Die casting process: die casting method, alloy characteristics, mold manufacturing.
2) Post-processing process: grinding, polishing, machining, spraying, electroplating, etc. Die castings adopt different surface treatment methods according to their different use environments, and the requirements of subsequent processes should be considered in the design.
2. Product Analysis
According to the user's requirements for the product, design and manufacture the mold to meet the requirements of the die-casting production process. Through the analysis of product characteristics and production, guide mold design, manufacturing, and die-casting production
1) Metallurgical standards: alloy grade, chemical composition, and mechanical properties.
2) Die-casting design standards: structure, shape, size, precision, tolerance, etc.
3) Cost budget: material cost, die-casting cost, mold cost, post-processing cost, and management cost.
Through the above analysis, the designed product conforms to the die-casting specifications, finally obtains the best quality and output requirements, and saves manufacturing costs.
