Rotational Steel Mold

Rotational Molds

<div class="fr-view sa_b_component_richtext_unique">In iron rotational steel mold, most of them are made of low carbon steel materials, which is because low carbon steel has the advantages of high strength, good thermal conductivity, easy modeling, convenient source, cheap price, etc., and is one of the two materials most suitable for making rotoplastic molds. Under normal circumstances, the thickness of the steel plate used to manufacture the rotoplastic mold is below 5mm, of which the most used steel plate varies from 1mm to 3mm, which depends on the size, structure, quantity of the product, the type of equipment used in the rotoplastic molding, the frame structure of the mold and other factors. If the mold wall is too thin, the strength is not enough and the service life is short. If the mold wall is too thick, it will lead to slow molding heating, waste energy, affect production efficiency, and the weight of the mold is too heavy, which is easy to cause damage to the rotolizing equipment. In addition, the thicker the steel plate is, the more difficult it is to make the mold, which increases the production cost and production time of the mold. At present, the domestic use of 45 high-quality carbon steel to make molds, but the need for heat treatment. The disadvantage of using carbon steel plate to make a mold is that the mold is easy to rust when it is not used for a long time, affecting the service life of the mold. Iron molds are basically made of sheet metal. Under normal circumstances, the product volume is large, the structure is simple, the precision is not high, the shape of simple rotomolding products are more suitable for processing and production with iron molds.&nbsp;Due to the increasing application of CNC machining machine tools in mold making, the precision and complexity of steel plate dies are also increasing.</div>

The cost of steel molds is relatively low, generally around 50% of the cost of aluminum molds. The thickness of steel molds is typically about 2.5 times that of aluminum molds. Steel molds have a service life of 8,000-10,000 cycles, which is on par with the performance of aluminum molds. The operation of the two mold types is essentially no different, but the sealing bolts on steel molds are relatively more complex to operate.
