造型机技术技巧之湿砂造型法：湿砂造型法。威利德造型机认为：适用于大部分金属材质、大批量生产的造型法中，粘土湿砂造型是最经济的造型法。铸造工厂装备有最新技术的控制装置，就应逐步做到，用湿型砂控制技术可以反复得到最佳的性能。这些控制装置包括，筛分分离金属、回用砂的冷却、回用砂混练时准确释量添加剂等等。
The wet sand moulding method of moulding machine technical skill: the wet sand moulding method. Willide moulding machine believes that clay wet sand moulding is the most economical moulding method suitable for most metal materials and mass production. Casting plant equipped with the latest technology of control devices, it should be gradually achieved, using green sand control technology can repeatedly get the best performance. These control devices include screening and separating metals, cooling of recycled sand, accurate release of additives when recycled sand is mixed and scoured, and so on.
现在的粘土湿砂造型机具有优良的性能，能以二年前从未达到过的速度，制造要求严格、允许差别很小时湿砂型。再加上准确控制效率高的供砂装置，使粘土湿砂型在铁基合金和非铁合金的造型中保持最重要的地位。
Now the clay wet sand moulding machine has excellent performance. It can manufacture wet sand moulds at a speed never reached two years ago. It has strict requirements and allows very small differences. The clay wet sand moulds are the most important moulding materials for ferroalloys and non-ferroalloys.
在湿砂造型中，垂直分型与水平分型两种加以比较，对于大批量生产中、小型，灰铁件或球铁件的铸造工厂，重直分型造型都占优势，因其设备费用比较便宜、可以高速造型、所需人员少、紧实度的偏差小等优点。但采用垂直分型工艺，在浇口方案与昌口与形态上，以及在用复杂的芯子、过滤片、冷铁、套管、舂入芯等方面都受到限制。此外，用流动性好的合金铸造时，由于金属静压比较高，容易引起金属渗透粘砂。
In wet sand moulding, vertical moulding and horizontal moulding are compared. For large-scale production of small and medium-sized foundries, gray iron or ductile iron castings, heavy straight moulding is advantageous because of its low equipment cost, high-speed moulding, fewer personnel required, and small deviation of compactness. However, the vertical parting process is limited in gate scheme and shape, as well as in the use of complex cores, filters, chills, sleeves and cores. In addition, when casting with good flowability alloys, metal penetration and bonding are easy to occur because of the high static pressure ratio of metals.
