How to select materials for non standard ejector pin and sleeves customized

In the processing of mold parts, choose the right material, has completed a big step. So, when customizing the non standard ejector pin and sleeves, how to choose the material? There are too many manufacturers of cylinder thimble on the market. Today, Yize, a manufacturer of precision non-standard mold accessories, tells you how to choose the material of the ejector pin and sleeves.

Non standard ejector pin and sleeves is most commonly used in plastic mold, used to separate products from the mold, therefore, plastic mold accessories thimble need to have good wear resistance, in the selection of materials, to choose wear-resistant, high temperature resistant, high toughness materials.

What are the materials with these characteristics? Generally, when customizing the non-standard ejector pin and sleeves, the material hardness is required to be 50-60 degrees. The materials with these requirements include SKH51, SKD61, SKD11, 65Mn, cpm10v, etc. Among these materials, the toughness of SKH51 is relatively higher, but the price is also more expensive, followed by SKD11 material; while 65Mn material is brittle and easy to break, most plastic molds are not equipped with 65Mn thimble; if the hardness of 50-60 fixture is required, and there are no other special requirements, it is recommended to use SKD61 material, which has relatively high cost performance and high temperature resistance After surface nitriding treatment, the wear resistance can be improved, which is a good material choice.

I believe that when you customize the non standard ejector pin and sleeves, many manufacturers will compare the prices, but the price is not the only factor to consider. You should also consider the scale, production equipment, production capacity, delivery quality and other comprehensive strength of the manufacturers. Generally, the manufacturers with high comprehensive strength will have more guarantee after-sales. It is necessary to compare the prices of three manufacturers, so as to find the suitable manufacturers.
