High-Precision Front Guard Turn Angle Protection Cover Mold - 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
◎ Both the cavity and the core material are made of P20 steel, which has high hardness and wear resistance, extending the mold life.
-
2High-Efficiency Cooling System
◎ Water-cooled design accelerates the molding cycle and improves production efficiency.
-
3Precise Demolding Structure
◎ Pin-type ejector + ejector plate double safety ensure smooth demolding of complex curved surface parts.
-
4Dual-Groove Design
◎ Right and left grooves adapt to different steering system requirements, enhancing versatility.
-
5Hybrid Gate System
◎ Hot runner + ordinary side gate combination, reducing waste and ensuring injection uniformity.

QWhat material is used for the mold cavity and core?
Both the cavity and core are made from P20 steel, known for its high hardness, excellent wear resistance, and long service life — making it ideal for high-volume automotive part production.
-
QWhat type of cooling system does this mold use?
The mold utilizes a water-cooled cooling system, which effectively accelerates the molding cycle, shortens production time, and improves overall efficiency.
-
QWhat is the dual-groove design and why is it important?
The dual-groove design includes both right-thread and left-thread grooves within the same mold. This allows the mold to produce dust covers compatible with different steering system configurations, greatly enhancing the product's versatility and applicability.
-
QWhat gate system does this mold use?
The mold uses a hybrid gate system combining a hot runner system with an ordinary side gate. This combination reduces material waste, ensures uniform plastic injection, and maintains consistent part quality.
-
QHow does the ejection system work for complex-shaped parts?
The mold employs a pin-type ejector combined with an ejector plate as a dual-safety demolding mechanism. This design ensures smooth and reliable ejection of complex curved surface parts without damaging the finished product.
-
QIs this mold suitable for mass production?
Yes. The mold design carefully balances production efficiency with long-term durability. With P20 steel materials, water cooling, and a reliable ejection system, it is well-suited for large-scale industrial production of automotive steering shaft dust covers.
