High-Precision China Front Guard Turn Angle Protection Cover Mold - Trusted Suppliers & Factory for Automotive Parts

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

Frequently Asked Questions

• 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 pre-hardened tool steel known for its high hardness, excellent wear resistance, and long service life — making it ideal for high-volume automotive part production.
• Q What type of gate system does this mold use, and what are its advantages?
  This mold uses a hybrid gate system combining a hot runner system with a normal side gate. This combination minimizes material waste, ensures uniform injection of the melt, reduces cycle time, and delivers consistent part quality across production runs.
• Q How does the dual-groove (double cavity) design benefit production?
  The dual-groove design features both a right-thread and a left-thread cavity within a single mold. This allows the simultaneous production of both steering variants, increasing versatility, reducing tooling costs, and improving overall production efficiency for different vehicle steering system requirements.
• Q What ejection system does this mold use, and why is it suitable for complex parts?
  The mold employs a dual-safety ejection system consisting of a pin ejector combined with an ejector plate. This configuration ensures smooth, reliable demolding of complex curved surface parts like dust covers, preventing deformation or damage during ejection and reducing downtime.
• Q Is this mold suitable for large-scale mass production?
  Yes. The mold is engineered with a water-cooled system to accelerate cycle times, durable P20 steel components for extended mold life, and a balanced gate design for consistent output. Together, these features make the mold highly suitable for large-scale, continuous industrial production environments.
• Q What types of vehicles or applications is this steering shaft dust cover mold designed for?
  This mold is designed for a wide range of automotive applications, including passenger cars and commercial vehicles. It produces dust covers that seal the steering tie rod-to-gear connection, protecting ball joint lubrication from dust and mud ingress — a critical component in steering system reliability and longevity.
