How do customers choose casting molding machines based on their own products and workshop conditions:

(1) Casting accuracy: When castings with high dimensional accuracy and high surface roughness requirements occur, a molding method with high compactness of sand mold should be chosen.

(2) Casting material: Different casting materials have different requirements for sand mold stiffness. Generally, the requirements for cast steel and cast iron are higher than those for non ferrous alloys, while ductile iron is higher than gray iron and malleable cast iron. For materials with high requirements for sand mold stiffness, it is advisable to choose a molding method with high sand mold compactness.

(3) Mold structure: For example, when the casting has narrow grooves, high hanging sand, dense air holes, etc., a molding method with high mold lifting accuracy and uniform sand mold compaction should be selected.

(4) Casting yield, batch size, and variety: For castings with high yield, large batch size, and single variety, it is recommended to use high-efficiency or specialized molding equipment; Small batches and multiple varieties of castings should use molding equipment with flexible processes and convenient production organization. Handmade styling is preferred for single piece production.

(5) Casting shape, size, and weight: When conditions permit, castings with similar shapes, but little difference in size and weight should use the same molding machine. This is especially true when the sand box needs to be equipped with straps to facilitate the uniformity of the sand box.

(6) Requirements for molding sand: When arranging multiple sets of molding machines on the same production line, it is advisable to consider the requirement of unified molding sand when selecting molding machines.

(7) The configuration equipment of the modeling workshop: This is particularly important during the renovation of the old workshop. It is necessary to combine the production capacity, process level, transportation conditions, and process flow of the original workshop workshop conditions, other supporting equipment (such as furnaces and sand treatment), and analyze them from a systems engineering perspective to determine which modeling machine is the most suitable for selection, in order to maximize investment benefits.

(8) Tooling conditions: The dimensional accuracy and surface roughness level of the pattern should match the selected molding machine.

(9) Priority should be given to selecting less and pollution-free (low noise, no harmful gases emitted) styling equipment that can meet environmental protection, industrial hygiene, and labor safety requirements.

(10) Efficient molding machines should be equipped with molding lines instead of being used separately.
