Core Product & Service: Aluminum Alloy Die Casting Mold Design & Fabrication
Our core business focuses on the customized design and manufacturing of high-precision aluminum alloy die casting molds, which serve as the core production equipment for realizing integral forming of aluminum alloy components via high-pressure die casting technology. Our core function is to deliver durable, high-performance die casting molds that ensure uniform aluminum alloy melt filling, consistent dimensional accuracy, and excellent structural density of cast parts—critical for components demanding load-bearing capacity, corrosion resistance, and seamless assembly. Backed by a professional team of 35+ engineers and technicians, we leverage advanced CAD/CAM/CAE software (UG, AutoCAD, SolidWorks) to conduct in-depth simulation and optimization of the aluminum alloy die casting process. This includes simulating melt flow, heat transfer, and solidification to optimize mold cavity structure, gating system, exhaust layout, and cooling design, thereby preventing common defects such as porosity, shrinkage cavities, and cold shuts. Our molds are tailored to match the properties of various aluminum alloy materials (e.g., ADC12, A380, A356, 6061) and the mass production needs of different industries, featuring exceptional high-temperature resistance, stable filling performance, and extended service life.
Production Process & Supporting Technologies
The production of our aluminum alloy die casting molds adheres to a strict industrial-grade standardized workflow, emphasizing precision, reliability, and process controllability: 1. Demand Analysis & Design (Collaborate with clients to confirm component specifications, performance requirements, aluminum alloy material selection, and production capacity; conduct 3D mold modeling and CAE die casting process simulation to verify melt filling uniformity, structural strength, and defect risk); 2. Raw Material Preparation (Select high-quality die casting mold steel (H13, SKD61, P20) with superior high-temperature resistance and wear resistance, suitable for aluminum alloy die casting; implement precision cutting via CNC flame cutting equipment);3. Precision Machining (Perform CNC milling, grinding, EDM, wire cutting, and high-speed machining to ensure the machining accuracy of mold cores, cavities, and gating components, with key dimensions controlled within ±0.005mm; focus on mold surface hardness treatment (HRC 48-52) to enhance wear resistance); 4. Assembly & Debugging (Skilled technicians conduct manual assembly, install temperature control systems and high-efficiency exhaust components, and perform multiple rounds of debugging on die casting machines to optimize parameters such as injection speed, pressure, and mold temperature); 5. Quality Inspection & Delivery (Use coordinate measuring machines (CMM), X-ray flaw detectors, and hardness testers to inspect mold dimensions and internal quality of trial castings; conduct performance tests to ensure compliance with industrial standards and provide detailed test reports). In addition to die casting mold design and fabrication, we also offer supporting processes such as post-casting machining (milling, drilling, tapping), surface treatment (anodizing, powder coating, electroplating), and finished product assembly, delivering a full-chain one-stop service to clients.
Common Problems & Solutions in Aluminum Alloy Die Casting Mold Design & Fabrication
• Problem 1: Porosity and shrinkage cavities in aluminum alloy castings - Solution: Utilize CAE simulation to optimize the mold’s exhaust system, adding exhaust ports and vents in gas-trapping areas to discharge air and molten aluminum vapor; Adjust die casting parameters (increase injection pressure, shorten filling time) to improve melt density; Preheat the mold to 180-250℃ to avoid rapid cooling and gas solubility increase; Select low-gas-content aluminum alloy materials and conduct degassing treatment before casting.
• Problem 2: Dimensional deviation of cast parts affecting assembly - Solution: Enhance mold machining precision, controlling key dimensions within ±0.005mm; Optimize the cooling system layout to ensure uniform cooling of the mold and reduce thermal deformation of cast parts; Adjust holding pressure and cooling time to compensate for aluminum alloy shrinkage; Conduct multiple rounds of trial casting and dimensional calibration to ensure mold stability.
• Problem 3: Cold shuts and incomplete filling of cast parts - Solution: Improve the gating system design, adopting a multi-point balanced gating structure to ensure rapid and uniform melt filling; Increase molten aluminum temperature (650-720℃) and mold temperature to enhance fluidity; Optimize mold cavity structure, eliminating narrow channels that hinder melt flow; Increase exhaust capacity in cavity dead corners.
