JinYi Mold focuses on the development and manufacturing of Air Intake Manifold Injection Mold, the core component of automobile engines. The intake manifold is responsible for evenly distributing air to each cylinder. The smoothness, dimensional accuracy and long-term thermal stability of its internal flow channels directly affect the intake efficiency, combustion performance and emission levels of the engine. With its deep experience in the field of complex automotive components, JinYi Mold provides reliable intake manifold injection molding solutions for high-performance racing cars, heavy-duty commercial vehicles, and even new-generation hybrid/electric vehicle platforms.
Our molds not only serve OEMs, but their precision standards are also recognized by top professional automotive tool manufacturers such as Milwaukee and are used to manufacture high-demand plastic components in their equipment.
We understand the stringent requirements of automotive powertrain components and combine computational fluid dynamics (CFD) analysis with precision tooling processes. From flow channel optimization through aerodynamic simulation (CFD) to full-process manufacturing in compliance with IATF 16949 standards, we are committed to producing precision plastic manifolds that can improve the overall efficiency of the engine and can work stably for a long time in high and low temperature cycles and vibration environments.
Key points of systematic engineering technology
Performance design:
In the early stages of mold design, we combine mold flow analysis (Moldflow) and computational fluid dynamics (CFD) for collaboration. Moldflow ensures uniform material filling, optimal welding line position, and effective control of warpage; while CFD focuses on optimizing the shape of the airflow channel inside the manifold to reduce eddy currents and pressure losses to improve the engine's volumetric efficiency. This dual simulation-driven design solution ensures that the finished product has excellent manufacturing feasibility and superior physical properties.
Mold manufacturing:
Due to the complex shape and deep cavity structure of the manifold, the mold often uses multiple sliders, inclined roofs and hot runner systems. We use high wear-resistant hot work mold steel such as H13, and use 5-axis CNC machining and precision EDM (electrical discharge) to ensure the surface quality and dimensional accuracy of the cavity. For large-scale production needs, we provide a stack mold (Stack Mold) solution, which can increase the output of a single injection molding and reduce the cost of a single component.
Materials and technology:
We are good at processing high-performance engineering plastics such as glass fiber reinforced nylon (such as PA66-GF30/35) to meet the manifold's requirements for high temperature resistance, engine oil resistance, and creep resistance. The mold design supports insert injection molding to integrate sensor brackets, metal thread inserts or other functional components to achieve a high degree of integration. Our partner network includes specialist low-roof car jack manufacturers, reflecting our proven ability to handle high-strength, high-precision structural components.
Validation and Quality Assurance
We follow the highest standards of the automotive industry's verification process to ensure that each intake manifold meets the demanding requirements of the engine.
Whole-process process monitoring and optimization:
In the high-standard production environment represented by automotive tool sets, we conduct closed-loop monitoring and data collection of the injection pressure, speed, and temperature of the injection molding process to ensure process stability.
Comprehensive performance and durability testing:
Products must pass strict inspections including three-dimensional coordinate (CMM) dimensional inspection, air tightness (leakage) test, burst pressure test, hot and cold shock cycle test and vibration fatigue test. These tests ensure the manifold's lifetime reliability in the extreme engine room environments.
Complete standardized document delivery:
We will provide a PPAP (Production Part Approval Process) document package, which includes design records, process flow diagrams, control plans, performance test reports and material certifications to support the review and mass production approval of the OEM or first-tier supplier.
