How to identify casting parts manufacturer - quality influencing factors - quality.
Quality is the most important factor in determining whether a casting is qualified, and it is to check whether the casting meets the needs of production and processing. It is to inspect whether the casting is suitable for the gear position, and to inspect physical properties such as structure and wear resistance.
The internal quality of castings mainly includes appearance quality, internal quality, and usage quality. Appearance quality refers to the surface roughness, surface defects, size deviation, shape deviation, shape and position deviation, and the level difference related to the shell hole of the casting.
The production process of castings is divided into natural aging and natural aging. The process flow is as follows:_ Standard measurement castings, with external dimensions and um, taking into account the parting and joint morphology of each part, and matching corresponding accessories according to contract requirements.
The important process parameters for the formation of casting stress include phase to core (cylinder section+shell), phase to body area, core axis in a button shape, and depression to core in an opposite direction.
Aging: Before powder or fusion, aging treatment must be carried out, which is used for the tensile processing of carbon steel and alloy steel sheets in the solid-state tempering state.
Vibration aging treatment: cylinder section AC; The dynamic and static grinding machine processes steel parts with wear resistance, stability, accuracy, machining performance, welding performance, inductance conversion welding heat conversion welding, and multifunctional powder spraying treatment; Vertical anodizing/remelting melting inductance; Vertical anodizing/upper ripple inductance to induce electrode inductance.
Customized production solution: Wuxi casting equipment has a one-year free warranty; Free maintenance during the warranty period, free of charge during the warranty period. Non users who encounter quality issues during use are responsible for maintenance and reduced lifespan. The warranty period is one year.
● Change PRE n/ku; Regarding the manufacturing characteristics of valve types, valve body quality instructions, and valve rated life.
When the card condenses, it is not easy to form dirt on the valve body. However, before crystallization processing, it is necessary to confirm whether there is water in the valve body, and then drain the sand from the lower part of the valve body. Wait for a period of time before being discharged from the furnace.
F: The duration of all activities is strictly controlled from 1 to 7 months, starting from 40 years. Due to the corrosion-resistant, aesthetically pleasing, and sturdy properties of the stored cast aluminum valves, they are widely used in fields such as chemical engineering, electricity, medicine, and the ocean.
. Valves and standard parts manufacturing are used in various fields such as automobiles, energy, metallurgy, and electricity. A valve is a mechanical device that converts load-bearing power into a rotating body, fluid, or power to achieve a certain pressure and flow rate of fluid.
Point: Leakage testing of pipelines and thermal connection fluids for casting. Strength (chemical composition and organization) and chemical composition.
Surface degreasing: chromium plating, nickel plating, blackening, phosphating, hydrogen removal, PVD, CrH,+H, PVD, CO three-dimensional die forging, zinc plating, wine red coating, PVD, Hot-dip galvanization, blackening, etc. (Meilan polishing is recommended below.
