1、根据不同形状的产品做模具。模具分上下凹模方式，通过车、刨、铣 、蚀、电火花等综合工序完成。凹坑形状、尺寸跟产品半边一致。因为腊模主要用于工业蜡压型使用，因此选用熔点不高，硬度不高、要求较低、价格较便宜、重量较轻的铝合金材料做模具。     2、利用铝合金模具生产出大量的工业蜡实芯模型。在正常情况下一只工业蜡实芯模型只能对应出一只毛坯产品。     3、对蜡模周边余量进行精修，去毛刺后将多个单一蜡模粘在（又称组树）预先 准备好的模头上，此模头也是用蜡模生产出的工业蜡实芯模型。（外形很像一棵树）  4、将已固定在模头上的多个蜡模涂上工业胶水后均匀喷上第一层细砂（一种耐火砂、耐高温，通常用的是硅沙）。此砂颗粒很小、很细，这样能确保最终毛坯表面尽量的光滑。  5、在设定的室温（或恒温）下让喷了第一层细砂的蜡模自然风干，但不能影响内部蜡模形状变化，自然风干的时间取决于产品本身内部的复杂程度，一般精铸件第一次的风干时间大约在5—8小时左右。  6、第一次砂喷完并自然风干后，在蜡模的表面继续上工业胶水（硅溶浆），并喷上第二层砂，第二层砂颗粒大小要比之前的第一层砂来的大、来的粗。喷完第二层砂后也是在设定的恒温下让蜡模自然风干。

1, according to different shapes of products to mold. The die is divided into upper and lower die, through the vehicle, planer, milling, etching, EDM and other integrated processes. The pit shape and size are consistent with the product. Because the wax mould is mainly used in industrial wax pressing type, the aluminum alloy material with low melting point, low hardness, low requirement, cheaper price and lighter weight is used as the mould. 2, a large number of industrial wax solid core model is produced by aluminum alloy mold. Under normal circumstances, an industrial wax core model can only correspond to a rough product. 3, the wax surrounding margin finishing, deburring after multiple single stuck wax (also known as group tree) die beforehand, the die is also used in industrial wax wax to produce solid core model. (much like the shape of a tree), 4 will have multiple fixed wax on the die coating industry after the glue evenly sprayed on the first layer of fine sand (usually with a refractory sand, high temperature resistant, is silica sand). This sand particle is very small and very thin, so as to ensure that the final blank surface as smooth as possible. 5, set at room temperature (or temperature) to spray wax first layer of fine sand to dry naturally, but does not affect the internal wax shape change, drying time depends on the complexity of the product itself, general casting the first drying time is about 5 - 8 hours. 6, the first sand spraying and natural dried wax on the surface, to industrial glue (Silica Sol Slurry), and sprayed with second layers of sand, second sand particle size to the first layer of sand than before to large, rough. After spraying second layers after sand is set at a constant temperature for wax to dry naturally.

7、第二次砂喷完并自然风干后，依次类推进行第三次喷砂，第四次喷砂，第五次喷砂等工序。 要求：  -           根据产品表面要求，体积大小，自重等相应调节喷砂次数。一般情况下喷砂次数为3-7次。  -           每次喷砂的砂粒大小均不一样，通常后道工序的砂粒均较前道工序砂粒粗，风干的时间长短也不一样。一般一个完整的蜡模上砂的生产周期为3~4天左右。    8、将已完成喷砂工序的蜡模在烘烤工序前，再均匀涂上一层白色的工业乳胶（硅 溶浆），以起到粘结和固化砂型，以及密封蜡模作用，为后道烘烤工序做准备。同时在烘烤工序后，还能提高砂型的脆性，便于敲碎砂层，取出毛坯。

After 7 and second times of sand spraying and natural drying, third times of sand blasting, fourth sand blasting, fifth sandblasting and so on. Requirements: according to the product surface requirements, size, weight and other corresponding adjustments sandblasting times. In general, the number of sand blasting is 3-7 times. The sand size of each sandblasting process is different, and the sand in the subsequent process is coarse than that in the previous process, and the drying time is different. Generally a complete wax on the sand production cycle for 3~4 days. 8, will be completed in the baking process of wax blasting process, and then evenly coated with a layer of white latex (industrial silicon soluble), so as to bond and curing sand, and sealing wax, to prepare for the post baking process. At the same time in the baking process, but also improve the brittleness of sand, easy to break out of the sand, blank.
