Experience In Barrel Mold Manufacturing


    We are a professional mold manufacturer. Our products are Bucket Moulds. We have summarized some technical points in the design and manufacture of paint bucket molds to share with you, and hope that these technical points can help you choose a partner.
    1. Professional bucket mold design is the principle of a good bucket mold.
    Especially in terms of cooling system design, in our company, we have designed a cooling system in the core, slider, scraper, and cavity.
    For the paint bucket mold core, design a cooling channel 15mm below the molding surface, and the diameter of the paint bucket mold cooling channel should be greater than 12mm, so that the water flows smoothly in the channel while taking away the heat in the core.
    For the paint bucket mold cavity, the design of the cooling system near the tip of the hot runner is very important, which is very sensitive. A poor cooling system will directly affect the cycle time and appearance of the bucket.
    2. It is very important to choose the right bucket steel.
    In order to manufacture high-quality paint bucket molds, we must choose the right steel for the bucket mold.
    Generally, for a mold with a paint bucket mold life of 1 million, it is recommended to use HRC35-38 to select 2738 as the cavity and core steel.
    For molds that require more than 3 million paint bucket mold life, it is recommended to use HRC45-48 to select 2344 cavity and core steel.
    Of course, some customers want to achieve high-speed injection with a shorter cycle time. We recommend using BeCu inserts on the top of the core, the bottom of the cavity and the slider.
    3. The precise mold ensures uniform injection and material flow.
    The core of the paint bucket mold is eccentric, resulting in uneven wall thickness and eccentric bucket.
    This problem is very common, but it is harmful to the life of the mold.
    Therefore, good and accurate processing technology selection is very important.
