Sand box selection and EPC equipment is also a relationship, if it is automatically closed production lines common to use pulleys flasks, of course, the shape of the track rail bearing sand box run, sand box model, it is associated with EPC production line phase supporting Weihai sand box, must match in order to reasonable use, sand box sales, but also a clear sand box size limit, too small can not make the normal operation of the production line; semi-automatic production lines open and easy to use sand EPC equipment boxes are basically the same, under normal circumstances is (except in exceptional circumstances) without wheels; then select the type of sand box, also in accordance with the requirements of casting design, such as most of the cast is generally used to me, but some special pieces must round box used to achieve the best results in the use; and finally sand box size choices, mainly based on casting size, but also consider the ability of the amount of solution and vacuum furnace, is the need for these designers known conditions first design, is a box of one or more pieces of cast or cast in several boxes at the same time, we must invest in advance before the design is good, sand box manufacturers, to prevent unnecessary losses occur in production or pre-production time . Principles of foundry sand box sand core production division side should be selected in accordance with the: try to make (1) foundry sand box when making sub-surface sand core surface and sand sub box consistent to ensure the sand core draft angle and look like a draft angle size and in the same direction to ensure a uniform thickness of the casting; (2) foundry sand box should give priority to the production of sub box straight face, sometimes in order to fit the shape of the sand core, you can use a surface or sub-surface folding boxes ; (3) the production of foundry sand box should have a greater open face, is conducive to sand core is filled with tight, and easy to use and set up sand cores mounted core gas path; (4) making the most of the foundry sand box drying the support so that the sand core surface is a flat plate structure in order to simplify the drying, the increased drying universal board; (5) When making foundry sand box size requirements as much as possible with a high portion on the core box, avoid sub-box surface segmentation; (6) the production of foundry sand box should be the core box structure is simple, easy to manufacture, easy to operate system core, and to meet the accuracy requirements of the sand core size.
