High-Precision Mold for Automotive Steering Protection Cover - China Suppliers & Factory
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.
-
1High Wear-Resistant Materials

Q What material is used for the cavity and core of this steering shaft dust cover mold?
Both the cavity and the core are made from P20 steel, a premium tool steel renowned for its high hardness, excellent wear resistance, and long service life, making it ideal for high-volume automotive injection molding applications.
-
Q What is the purpose of the dual-groove (right thread + left thread) design?
The dual-groove design — incorporating both right-hand and left-hand thread grooves — allows the mold to produce dust covers compatible with different types of steering systems. This enhances the mold's versatility and reduces the need for separate tooling for left and right applications.
-
Q How does the cooling system improve production efficiency?
The mold features a water-cooled cooling system that rapidly dissipates heat from the molded part after injection. This significantly shortens the cooling phase of each cycle, reducing overall cycle time and increasing production output without compromising part quality.
-
Q What type of gate system does this mold use, and what are its advantages?
The mold uses a hybrid gate system combining a hot runner system with a conventional side gate. This combination minimizes material waste by keeping the runner hot and reducing cold-runner scrap, while the side gate ensures uniform plastic flow for consistent, high-quality parts.
-
Q What industries and applications is this mold suitable for?
This mold is primarily designed for the automotive manufacturing industry, specifically for producing steering system dust covers and seals for passenger cars and commercial vehicles. It is also suitable for precision injection molding of other rubber and plastic protective parts and supports large-scale mass production requirements.
-
Q How does the ejection system ensure safe and smooth demolding of complex parts?
The mold employs a dual-safety ejection system combining pin-type ejectors with an ejector plate. This two-stage mechanism evenly distributes ejection force across the part surface, preventing deformation or damage during demolding — even for parts with complex curved surfaces such as steering shaft dust covers.
