High-Quality Front Protection Plate Mould from China Suppliers | Efficient Production at Factory Prices
Product Overview
This mold is a large injection mold specifically designed for automotive front protective panels (such as A-pillar upper panels). By optimizing the gating system and core-pulling mechanism, it solves the problems of difficult filling of thin-walled parts and easy breakage of angled ejector pins. Both the mold cavity and core material are made of P20 steel, and the mold base is made of 45# steel. It is equipped with a water cooling system and a hot runner + side gate combination injection system to ensure high precision and durability.

Frequently Asked Questions
-
Q What material is used for the mold cavity and core of this automotive injection mold?
Both the mold cavity and core are made of P20 steel, which offers an excellent balance of hardness, toughness, and machinability — making it ideal for high-volume automotive part production.
-
Q What is the molding cycle time for this mold?
The molding cycle is ≤ 30 seconds, achieved through the optimized hot runner system that reduces material waste and maximizes production efficiency.
-
Q How does the core-pulling mechanism improve demolding stability?
This mold uses a double-slanted push rod core-pulling mechanism, which distributes ejection force more evenly across the part. This significantly reduces the risk of angled ejector pin breakage and ensures consistent, stable demolding for thin-walled automotive panels.
-
Q What type of gating system does this mold use?
The mold is equipped with a hot runner system combined with a normal side gate. This combination ensures efficient material flow, minimizes waste, and supports high-precision filling of thin-walled front protective panel parts.
-
Q How does the cooling system ensure dimensional stability?
The mold features a dedicated water cooling system that rapidly and uniformly controls mold temperature throughout each cycle. This precise temperature management minimizes warping and shrinkage, ensuring consistent dimensional accuracy of finished plastic parts.
-
Q Can this mold produce both left and right side panels simultaneously?
Yes. The mold features a 2-cavity design with one cavity for the right-side part and one for the left-side part. This multi-cavity configuration allows simultaneous production of both components, reducing secondary processing and improving overall manufacturing efficiency.
