Steel material selection for injection mold
Many people do not know how to choose the right steel for the production of injection molds. Choosing good, expensive, afraid of overkill. Poorly selected, cheap, and afraid of made plastic products can not meet the expected requirements and mold life. In fact, this is really the case, choosing the right steel is really crucial.
The first injection mold is the mold of our most common plastic daily necessities. Because most of the daily necessities do not have excessive requirements on mold precision, wall thickness, appearance, etc., plus the replacement of daily necessities is relatively fast, so the life expectancy of the mold is not very high, so generally choose 718 or P20 steel materials. .
Another ultra-thin box mold is a typical example. It seems to be simple in appearance, but the requirements for steel are very strict. S136 is generally used. Because the ultra-thin box requires a high wall thickness and is a high-speed running mold. The anti-corrosion performance of S136 satisfies the requirements of the ultra-thin box size. The hardness of S136 meets the requirements for high speed operation. Therefore, the ultra-thin box must choose S136 such as hard steel. At the same time, the copper on the core can better achieve the cooling effect.
There is also a plastic knife and fork spoon mold, the plastic of the cutlery spoon has two kinds of PP, PS. H13, S136, 2344, 2316 can choose a variety of steel materials, but most customers open a pair of molds to do two materials, we will make the mold according to the plastic shrinkage ratio of PS, generally use H13 steel.
