    Product Details

    Product Overview

    This mold is used to manufacture automotive steering shaft protective covers (dust covers). Its core function is to seal the connection between the steering tie rod and the steering gear, preventing dust and mud from entering and protecting the lubrication of the ball joint. The mold uses P20 steel cavity/core material and 45# mold base, combined with hot runner, water cooling system and double groove (right thread + left thread) design to meet the requirements of high-precision and high-efficiency injection molding.

    Product Features
    1

    High Wear-Resistant Materials

    ◎ Both the cavity and the core material are made of P20 steel, which has high hardness and wear resistance, extending the mold life.

    2

    High-Efficiency Cooling System

    ◎ Water-cooled design accelerates the molding cycle and improves production efficiency.

    3

    Precise Demolding Structure

    ◎ Pin-type ejector + ejector plate double safety ensure smooth demolding of complex curved surface parts.

    4

    Dual-Groove Design

    ◎ Right and left grooves adapt to different steering system requirements, enhancing versatility.

    5

    Hybrid Gate System

    ◎ Hot runner + ordinary side gate combination, reducing waste and ensuring injection uniformity.

    Frequently Asked Questions
    Q What material is used for the cavity and core of this steering shaft dust cover mold?
    Both the cavity and core are made from P20 steel, a premium tool steel known for its high hardness, excellent wear resistance, and long service life, making it ideal for high-precision injection molds.
    Q What is the purpose of the dual-groove (right thread + left thread) design?
    The dual-groove design allows the mold to produce two cavity versions — right-hand and left-hand — in a single setup, enabling the dust cover to fit different steering system configurations and significantly enhancing versatility for automotive manufacturers.
    Q How does the water cooling system benefit the injection molding process?
    The integrated water cooling system rapidly dissipates heat from the mold after each injection cycle, shortening the cooling time, accelerating the overall molding cycle, and boosting production output without compromising part quality.
    Q Why is a hybrid gate system (hot runner + side gate) used in this mold?
    The hot runner + ordinary side gate combination ensures consistent melt flow into the mold cavity, reduces material waste from runners, lowers production costs, and guarantees uniform injection quality — critical for achieving high-precision automotive sealing components.
    Q What types of vehicles or industries can this mold serve?
    This mold is suitable for automotive manufacturing across passenger cars and commercial vehicles, as well as for precision injection molding applications including automotive seals and protective covers. Its robust design also supports large-scale mass production requirements across various industrial sectors.
    Q How does the ejection system ensure reliable demolding of complex parts?
    The mold uses a dual-safety ejection system combining pin-type ejectors and an ejector plate. This configuration distributes ejection force evenly across the part surface, preventing deformation and ensuring smooth, reliable demolding even for components with complex curved geometries like steering shaft dust covers.
