This document is applicable to investment casting process design and process management.
2 Normative references
The contents of the following documents constitute the essential clauses of this document through normative references in this document.
For referenced documents without a date, only the version corresponding to that date applies to this document; for referenced documents without a date, the latest version (including all amendments) applies to
This document.
GB/T 5611 Casting Terminology
3 Terms and definitions
The terms and definitions defined in GB/T 5611 apply to this document.
4 Overall objectives of process design
The overall goal of process design is to meet casting quality requirements, reduce manufacturing costs, increase productivity, and continuously improve processes and optimize
structure, improve performance; on the basis of reducing the difficulty of casting process, reduce the consumption of raw and auxiliary materials and energy as much as possible; reduce the production process
Pollution to the ecological environment and harm to human safety and health.
5 Basic principles of process design
5.1 Principle of applicability
The process design should adopt advanced and practical new technologies, new materials, new processes and new equipment as much as possible to achieve efficient, low-consumption, clean and safe production
the goal of.
5.2 Principle of Efficiency
It is advisable to gradually eliminate inefficient process technologies and production equipment, use advanced process technologies and equipment, adopt new materials, and promote digital
ization, informatization, intelligentization and other technologies, strengthen the integration with new technologies and processes such as additive manufacturing, and improve the process output rate and product qualification rate.
5.3 Low consumption principle
5.3.1 The casting process should be reasonably designed to minimize the energy consumption, material consumption and labor cost of castings while meeting the quality requirements of castings.
5.3.2 Improve resource utilization, promote recycling technology, and reduce resource consumption per unit product (including raw materials, auxiliary materials, etc.)
materials, water, electricity, etc.).
5.3.3 Additive manufacturing technology should be used to prepare wax patterns, shells and cores in order to shorten the production cycle.
