the mold surface roughness is a very important technical parameter in mold making, because the surface finish of the molding area directly affects the surface roughness of the plastic part. […]
the number of molding cycles is less than 500 repetitions, used for a low-volume production such as prototypes. […]
the number of molding cycles is up to 100K, used to a low volume of plastic parts. Mold materials do not have to be highly wear-resistant. […]
the number of molding cycles is up to 500K, used for medium-sized production volume. This is the most frequently used mold class. […]
the number of molding cycles is between 500K and 1M, used for volume production. The molding area and related mold components needs heat treatment. Good mold materials are used. Additional requirement are listed below. […]
the number of molding cycles is higher than 1M repetitions, used to produce plastic parts at high volume. The molding area( including the slides and lifters in contact with melt plastic materials) is hardened. Best mold materials are used. Additional requirement are listed below: […]
there are many versions in mold grade description, actually, molds are subject to normal wear during it’s use, until the plastic part fails to meet it’s quality requirement. […]
As mold manufacturing in China has become more globally competitive, the necessity to reduce expensive, labor-intensive practices has become paramount for shop owners. The goal for most shops is to reduce or completely eliminate polishing or spotting time on their molds, which can be accomplished through the use of sinker EDMs, hard milling of steel [...]
We all know that EDM setup can be extremely time-consuming. Automating the setup process can save valuable time, especially when considering that some tools (especially those with multiple cavities) require dozens or even hundreds of electrodes. […]
today morning, I design a mold from USA, he requires his mold to use a Stack gate, I want to share it with everyone, stack gate has two or more regulated gates stacked on the same runner. […]
