High-Precision China Suppliers Mold for Front Guard Turn Angle Protection Cover – Durable Automotive Factory Solution
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.
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.
High-Efficiency Cooling System
◎ Water-cooled design accelerates the molding cycle and improves production efficiency.
Precise Demolding Structure
◎ Pin-type ejector + ejector plate double safety ensure smooth demolding of complex curved surface parts.
Dual-Groove Design
◎ Right and left grooves adapt to different steering system requirements, enhancing versatility.
Hybrid Gate System
◎ Hot runner + ordinary side gate combination, reducing waste and ensuring injection uniformity.
Automotive Manufacturing
Specialized in producing dust covers for steering systems to ensure ball joint sealing, suitable for manufacturing steering components for passenger cars, commercial vehicles, etc.
Precision Injection Molding
Suitable for high-precision rubber/plastic parts molding, such as automotive seals, protective covers, etc.
Mass Production

Both the cavity and core are made of P20 steel, which offers high hardness, excellent wear resistance, and ensures a long mold service life under high-volume production conditions.
The mold uses a hybrid gate system combining a hot runner and a normal side gate. This design minimizes material waste, reduces cycle time, and ensures uniform plastic flow during injection.
The dual-groove design includes both right-thread and left-thread grooves within a single mold (2 cavities). This allows the mold to produce dust covers compatible with different steering systems, greatly enhancing production versatility and efficiency.
The mold is equipped with a water-cooled cooling system. The water channels run through the mold to rapidly reduce temperature after each injection cycle, shortening the molding cycle and significantly improving overall production efficiency.
This mold is primarily designed for automotive manufacturing, particularly for producing steering shaft dust covers. It is also suitable for high-precision rubber and plastic parts molding, including automotive seals and protective covers, and is optimized for large-scale industrial mass production.
The mold uses a dual-safety ejection system consisting of both pin-type ejectors and an ejector plate. This combination ensures reliable and smooth demolding of complex curved surface parts without deformation or damage.
