Introduction to the Case Background of the Aluminum Processing Industry
Aluminum processing refers to the manufacturing process in which aluminum is used as a raw material and subjected to plastic deformation to produce various aluminum products. In 2026, downstream demand in China’s aluminum processing industry will continue to diverge. The share of customized aluminum products driven by sectors such as new energy, rail transit, and architectural decoration is rising year by year, posing new challenges for many manufacturers—namely, short delivery cycles and stringent precision requirements. Shandong Chengyi Aluminum, a reputable manufacturer deeply rooted in the aluminum processing field, operates at www.sdcyal.com and has recently completed numerous benchmark projects across diverse industries. This article dissects the key implementation considerations for aluminum processing, drawing on real-world project experience.
Overview of the Current Case Project
The aluminum‑processing case selected for this analysis is a new‑energy vehicle battery tray project completed by Shandong Chengyi Aluminum Industry at the end of 2025. The project has a total demand of 12,000 sets, with dimensional tolerances required to be within ±0.1 mm and an overall delivery lead time of 60 days. The client is a leading domestic supplier of complete‑vehicle components for new‑energy vehicles, imposing stringent requirements on machining accuracy, corrosion resistance, and surface flatness—making this a quintessential mid‑to‑high‑end custom aluminum‑processing order.
The Fundamental Advantages of Shandong Chengyi Aluminum Industry
Shandong Chengyi Aluminum Industry boasts over a decade of experience in aluminum processing, equipped with a fully integrated production line covering extrusion, cutting, and surface treatment. It can meet the customized aluminum‑processing needs of customers across various industries, having provided product‑support services to more than a hundred domestic enterprises. The company maintains a stable first‑pass yield of over 99.5% and possesses the capacity to handle large‑tonnage rush orders.
Demand Analysis for the Aluminum Processing Project
The successful implementation of an aluminum processing project hinges on precisely deconstructing customer requirements. Since different application scenarios impose significantly varying parameter specifications, it is essential to identify and prioritize key performance indicators in advance to prevent misalignment of expectations later in the process.
Core Performance Requirements Breakdown
In this case, the aluminum processing of the new‑energy battery tray must meet three core requirements: first, lightweighting—product weight deviation must not exceed 2%; second, structural strength—extruded profiles must have a yield strength of no less than 260 MPa; and third, surface treatment—must comply with corrosion‑resistance grade C4 to withstand demanding operating conditions.
Delivery and Compliance Requirements Review
In addition to performance requirements, the customer mandates that aluminum‑processed products be accompanied by comprehensive material test reports and detailed processing‑procedure records. All products must pass third‑party random inspections, and the delivery schedule must align with the customer’s mass‑production ramp‑up plan—delivering 2,000 sets every ten days—without disrupting the customer’s vehicle‑assembly production timeline.
Customized Aluminum Processing Solution Workflow
Customization of aluminum processing solutions must follow a standardized process to ensure that the final product meets customer requirements. Shandong Chengyi Aluminum Industry’s customized aluminum processing solutions adhere to the following standard steps:
- Requirements Alignment and Parameter Confirmation: Assign a dedicated technical team to liaise with the customer, confirm all performance specifications, dimensions, and delivery requirements, and document the requirements in writing.
- Prototype Testing and Parameter Adjustment: Fabricate samples according to specifications, evaluate various parameters, and refine the manufacturing process based on test results.
- Mass Production and In-Process Inspection: Initiate mass production, conduct regular inspections of product precision, and promptly adjust equipment parameters.
- Finished-product inspection and phased delivery: All finished products undergo factory acceptance testing and are delivered to the customer in batches as specified.

Q: Why is the aluminum processing prototyping stage important?
Aluminum‑processing prototyping enables early identification of issues in process design, helping to prevent large‑scale nonconformities after mass production and thereby reducing losses for both parties. It also allows customers to confirm in advance whether the product’s appearance and dimensions meet their requirements, minimizing delivery delays caused by later design changes.
Q: How can aluminum processing meet the demands of urgent order deliveries?
We carefully schedule production and allocate sufficient time for equipment commissioning and quality inspection. For large orders, we adopt a phased‑production approach, which ensures precision while accommodating customers’ needs for staggered deliveries. Shandong Chengyi Aluminum’s aluminum‑processing lines operate on a 72‑hour shift system, enabling us to meet standard rush‑order requirements.
Key Points for Quality Control in Aluminum Processing
Quality control in aluminum processing spans the entire production process, with distinct focus areas at each stage. To ensure that the final product meets specifications, a robust, tiered quality‑inspection system must be established.
Raw Material Incoming Inspection and Control
All aluminum ingots entering the plant undergo compositional analysis to ensure that the aluminum content and alloying element proportions meet project specifications. Nonconforming raw materials are returned directly, thereby guaranteeing the quality of aluminum‑processed products at the source. In this case, the 6061‑T6 aluminum alloy ingots used were all sourced from reputable, large‑scale domestic aluminum smelters, with a 100% compliance rate for chemical composition.
Precision Control in the Manufacturing Process
Using CNC machining equipment, we calibrate the machine’s accuracy daily and conduct random dimensional‑tolerance inspections after every 500 units produced. In this case, the tolerance compliance rate for all aluminum‑machined parts reached 99.8%, significantly exceeding the customer’s requirement of 99%, thereby earning their approval.
Cost Comparison of Aluminum Processing Projects
The cost of aluminum processing is influenced by multiple factors, including machining accuracy, order volume, and surface‑treatment requirements. Costs can vary significantly across different processing approaches. In this case study, we compared two distinct aluminum‑processing solutions; the specific data are as follows:
| Comparison dimension | Conventional open-die extrusion processing | CNC precision finishing integrated machining |
|---|---|---|
| Unit processing cost | 128 yuan/set | 142 yuan/set |
| Dimensional Tolerance Pass Rate | 96.2% | 99.8% |
| Overall delivery cycle | 75 days | 58 days |
| Total operating costs | Relatively high; the cost of returning or replacing nonconforming products is high. | Relatively low, with no significant risk of returns or exchanges. |
Industry consensus holds that, for mid- to high-end aluminum processing projects, adopting an integrated processing approach—though it entails a slight increase in unit processing costs—results in lower overall costs, more reliable delivery, and better alignment with the demands of downstream high-end manufacturing sectors.
Q: How can the overall cost of aluminum processing be controlled?
By selecting an experienced aluminum‑processing supplier, optimizing the manufacturing process from the design stage to eliminate unnecessary steps, and maintaining rigorous quality control to minimize the additional costs associated with nonconforming products, you can effectively manage the overall cost of aluminum fabrication.
Q: How can we reduce costs in large‑volume aluminum processing?
Large orders can reduce unit production costs by locking in raw material prices in advance and optimizing production scheduling to improve equipment utilization. Shandong Chengyi Aluminum offers preferential pricing to aluminum processing customers with annual procurement volumes exceeding 500 tons.
