Cavitation is a form of mold erosion that occurs during casting. In some critical areas of the dies, steel is removed and eroded by an aggression generated by micro-implosions of gases and vapors that occur during the filling of the cavity.
The rapid deterioration of the dies results in production stoppages and major maintenance operations that compromise the production efficiency.
In terms of mechanical strength, the breaking load is commonly defined as ultimate tensile stress (UTS), which is the maximum external force limit applied beyond which a material loses its functional specifications in terms of strength. Tensile strength tests vary according to the type of stress the material is subjected to, which we will describe later. In our case, are tests to be carried out on a component during production.
Zinc die casting is a process that consists in injecting the liquid metal under pressure into a mould, generally made of special steel, and letting it solidify. The die casting technique is the shortest way that leads from the metal in the liquid state to the finished product and has different fields of application (automotive above all, but also electronics, electromechanics, household appliances and in general all sectors that require non-ferrous metallic components).
Industrialization of the product is a very delicate phase in the process of production of zinc alloy die casts: in fact it is in this phase that, after receiving the order from the customer, all the procedures that are necessary to start mass production are defined.
Cost reduction in zinc die casting is an activity that shall be executed without affecting the quality and functionality of the component that is produced. All the activities that aim to increase productivity, to diminish scrap rate and to simplify productive processes, as well as the choices of materials and processing, are cost reduction strategies.
Zinc is a material that can be employed in several manufacturing sectors, including the branch of small appliances. The following post describes the main advantages of the use of zinc for the production of small appliances components, specifically of coffee machines components.
The term product design defines the process of designing a new product that has to be marketed in a specific business, taking into account not only its aesthetical characteristics but also its functions and its production cycle. Indeed, the product must meet the final user expectations while simultaneously be compliant with the production process.
Process improvement, in the zinc die casting industry as well as in many other manufacturing sectors, consists of a series of actions undertaken to enhance production times, to reduce costs and, consequently, to obtain results that satisfy client’s requests in terms of timing and performance.
In this post we are going to discuss the structure of die casting cycle time and how its optimization can bring various benefits for the company.
In this article we are going to analyze product design for die casting through the study of a DFM (Design for Manufacturability) and suggesting a way to optimize and speed up the process: co-design.
