Overview:
Our OEM High-Quality Extrusion Tooling Molds for New Plastic Door Frame Profiles are engineered for precision, durability, and efficiency in large-scale extrusion production. Designed to meet the strict dimensional and surface requirements of modern PVC, ABS, and composite door frame systems, these molds ensure excellent profile accuracy, smooth extrusion flow, and consistent wall thickness across extended production runs. Each tool is custom-developed based on customer specifications, enabling optimal material distribution, dimensional stability, and reduced die swell. With decades of experience in plastic extrusion mold design and fabrication, our factory provides end-to-end custom services, from CAD/CAE simulation and tooling design to final polishing and trial extrusion verification.

- Superior Surface Quality: Mirror-polished die lips and calibrators guarantee smooth extrusion surfaces and minimal friction.
- High-Strength Construction: Manufactured from premium alloy steels for extended die life and resistance to wear and corrosion.
- Thermal Stability: Advanced heat treatment and balanced cooling systems maintain steady temperature during continuous operation.
- Custom Engineering Support: Full DFM review, extrusion flow simulation, and on-site technical assistance for startup and tuning.
- Cost-Effective Longevity: Hardened tool steels and PVD coatings enhance lifespan and reduce maintenance cycles.
Surface Treatment Options:
- Hard Chrome Plating: Improves wear resistance and surface smoothness for polymer flow.
- Nitriding Treatment: Enhances hardness (up to HRC 60+) and corrosion resistance.
- PVD Coating (TiN/TiAlN): Minimizes friction and polymer adhesion during extrusion.
- Polishing & Passivation: Ensures corrosion protection and mirror-finish surface for aesthetic profiles.
Quality Assurance:
Every extrusion mold is subjected to strict in-house inspection and functional verification. Dimensional accuracy is validated using CMM and 3D scanning, while flow channel precision is verified through profilometry and optical surface measurement. During trial runs, we conduct extrusion flow balance testing and profile dimensional analysis to ensure uniform melt distribution and smooth surface output. Our ISO 9001-certified process guarantees full traceability from raw material to final die assembly.
Our Factory:
Our state-of-the-art manufacturing facility integrates high-speed CNC machining centers, EDM and WEDM-LS systems, and CNC grinders to ensure perfect alignment and geometry in every extrusion die. Advanced CAD/CAM/CAE platforms streamline design and process simulation, while robotic polishing lines and automated assembly stations maintain consistency and precision. Equipped with temperature-controlled finishing areas and die testing stations, we provide complete extrusion mold manufacturing solutions — from prototype to mass production tooling.
