Flywheel Housing Low Pressure Casting For Automotive Components

Technical Advantages

Full In-House Manufacturing

Mold design and fabrication, low pressure die casting workshop, heat treatment, CNC machining, surface treatment, and inspection lab — all centralized under one roof. No outsourcing. From molten aluminum to finished and blasted part, we maintain full control over lead time, quality consistency, and batch traceability.

Design for Manufacturability (DFM) Support

Before tooling production begins, we provide a detailed DFM report covering mold filling analysis, solidification behavior, riser and gate design, and machining allowance optimization. For flywheel housings like this 5.2 kg A356 component, we focus on wall thickness transitions between the bore hub and outer flange, riser placement to eliminate shrinkage in thick sections, and controlled cooling to ensure uniform mechanical properties across the entire casting.

Expertise in Complex Castings

We specialize in pressure-tight, structurally demanding aluminum castings — such as flywheel housings, crankcases, pump housings, and intake manifolds. Our low pressure die casting process delivers excellent internal soundness, reduced porosity, and uniform mechanical properties, while T6 heat treatment enhances strength and dimensional stability for precision machining. 

Certified Raw Material Sourcing

We charge only certified primary aluminum ingots into our electric melting furnaces. Chemical composition is spectrometer-verified and adjusted in real time before casting. Degassing and fluxing practices ensure clean molten metal with low inclusion content — critical for maintaining consistent A356 mechanical properties and pressure tightness across low pressure die casting production.

Full Batch Traceability

Every production batch is identified by a unique heat number. Chemical composition reports, mechanical test records (tensile strength, hardness, elongation), T6 heat treatment charts, and dimensional inspection data are compiled into a traceable dossier — from ingot lot to finished flywheel housing.

Extensive Alloy Expertise

We work with a comprehensive range of casting aluminum alloys — A356, A380, ADC12, A360, A413 — and can tailor alloy selection to your specific requirements. Whether your application demands pressure tightness for oil sealing, high strength with ductility for structural integrity, or thermal stability for engine environments, we match the alloy and heat treatment to your needs.

Service Advantages

 Dedicated Cross-Functional Support

A dedicated project manager oversees the entire process — from design review to final delivery — ensuring efficient communication at every stage and a single point of contact for all technical and commercial matters.

Fast Response & Transparent Communication

Quotations are typically provided within 24–48 hours. Production progress is updated regularly through photos and production data, with continuous customer feedback collection throughout the project. For automotive structural castings, first-article inspection reports including dimensional layout, concentricity measurement, and material certification are provided before batch production begins.

After-Sales Support

Full batch traceability and 24-hour response to quality-related issues ensure reliable post-delivery support. Flexible MOQ with pilot order options available for new die casting projects.
