We are Changzhou Hongxinyutai Precision Mold Co., Ltd., a manufacturer with over 7 years of specialized experience in precision mold solutions. Located in Changzhou, Jiangsu, China, our factory spans 1,000–3,000 square meters and is staffed by 51–100 skilled professionals. We are proud to hold TS16969 certification, which reflects our commitment to quality management systems in the automotive sector. Our Electric Vehicle Water Pump Mold Porous Steel Insert Outgassing Solution is specifically engineered to address the critical challenge of gas entrapment during high-pressure molding processes, ensuring superior part quality and extended mold life. This product is designed with the demanding requirements of the South Korean automotive market in mind, where precision and reliability are paramount.
Gas defects such as burn marks, voids, and short shots are common in injection molding of water pump components for electric vehicles. Our porous steel insert provides a controlled path for trapped gases to escape, dramatically reducing defects and improving cycle times. The insert is made from high-grade sintered porous steel, offering excellent thermal conductivity and mechanical strength while maintaining a uniform porosity that allows gas to vent without compromising the mold cavity's integrity. Below we detail the key features and specifications.
Key Features & Benefits
- Enhanced Gas Evacuation: The porous structure of the steel insert allows trapped gases (air, moisture vapor, and decomposition gases) to escape uniformly, preventing surface defects and internal voids.
- Extended Mold Life: By reducing the pressure buildup from outgassing, the insert helps minimize stress on the mold core and cavity, reducing wear and the risk of cracking.
- Improved Part Quality: Parts manufactured with this insert exhibit better surface finish, higher dimensional accuracy, and fewer rejects, directly contributing to cost savings.
- Customizable Porosity: The porosity level can be tailored to match the specific material viscosity and flow characteristics, ensuring optimal venting for each application.
- Compatible with High-Temperature Materials: Suitable for engineering plastics commonly used in EV water pumps, such as PPS, PPA, and PA66+GF.
- Easy Installation: Designed as a standard insert that can be retrofitted into existing mold bases without major modifications, reducing downtime.

Frequently Asked Questions
Q1: What is the main purpose of a porous steel insert in a mold?
A1: The primary function is to allow trapped gases (air, moisture, and volatile compounds) to escape from the mold cavity during injection or die casting. This prevents gas-related defects such as burn marks, voids, and short shots, resulting in higher quality parts and longer mold life.
Q2: Can the porous insert be used for materials other than plastics?
A2: Yes, it is also suitable for die casting of metals such as aluminum, zinc, and magnesium, as well as rubber molding. The operating temperature limit (400°C) makes it versatile for many high-temperature processes.
Q3: How do you determine the correct porosity for my application?
A3: We analyze the material viscosity, injection pressure, and part geometry. Typically, finer porosity is used for low-viscosity materials, while coarser porosity works better for high-viscosity melts. Our engineers can run simulations and recommend the optimal grade.
Q4: Does the porous insert require special maintenance?
A4: Minimal maintenance is needed. We recommend periodic cleaning to remove any residue buildup. This can be done by ultrasonic cleaning or using a solvent. The insert is durable and can last for hundreds of thousands of cycles if properly maintained.
Q5: What is the typical lead time for a custom insert?
A5: Lead time depends on design complexity and current workload. Standard ranges are 10–15 working days for simple geometries and up to 25 working days for complex ones. We offer expedited service for urgent orders upon request.
Q6: Are samples available for testing before bulk purchase?
A6: Yes, we can provide sample inserts (subject to a nominal fee) for you to test in your mold. The sample cost is deductible from the first order. We also provide technical data sheets to assist in evaluation.
Q7: Do you ship to South Korea directly?
A7: Absolutely. We regularly ship to South Korea via sea or air freight. Our export team handles all documentation, and we can arrange door-to-door delivery if required. Shipping time from Shanghai to Busan is typically 2–4 days by sea.
Q8: Is your product IATF 16949 certified?
A8: Our company is certified under TS16969, which is a predecessor and equivalent standard to IATF 16949 in terms of quality management requirements for automotive suppliers. We continuously work to meet the latest automotive industry standards, and we can provide our certificate upon request.
