Aluminum casting is a manufacturing technique in which molten aluminum is poured into a mold to produce precise and strong parts. The material is lightweight, corrosion-resistant, and has an excellent strength-to-weight ratio. Therefore, aluminum is widely used in industries such as mechanical engineering, automotive, agricultural technology, electronics, and consumer products. The major advantage of aluminum casting is that it can produce complex shapes that would be much more expensive, or even impossible, with CNC machining.
Outsourcing aluminum casting often occurs in countries with a strong casting industry, such as China, where both production costs and mold and die costs are significantly lower. This makes it attractive for developing new products or producing larger series. For smaller series or specific projects, it can also be worthwhile, but it depends on the casting method used.
Aluminum casting involves several processes, each with unique properties. The main casting methods are sand casting, gravity die casting, high-pressure die casting, lost-wax casting, and resin sand casting. Each technique has advantages and disadvantages in terms of accuracy, strength, surface texture, production costs, and batch size. The following sections discuss all casting methods in detail so you know exactly which technique is best suited for your application.
There are several methods for casting aluminum, each suitable for specific series, tolerances and complexity:
1. Sandcasting (Sand Casting)
4. Lost-wax casting (Investment Casting)
5. Resin Sand Casting (part of sand casting)
During this conversation we will briefly explain what we can do for you and answer your questions.
Based on your product and requirements, we request prices and delivery times from various suppliers.
We will then prepare a clear quote. Prices are quoted based on your terms and conditions.
Once you have approved our proposal, we will start making a prototype.
After approval of the prototype, the assignment will begin.
Casting aluminum offers significant advantages: the material is lightweight, strong, corrosion-resistant, and suitable for both simple and highly complex parts. Furthermore, production costs are relatively low compared to full machining, especially for larger quantities. Post-processing processes such as CNC milling, tapping, or surface treatment ( powder coating, anodizing, shot blasting ) can also be easily integrated into the production process. Furthermore, the parts can be assembled directly when needed.
Outsourcing aluminum castings to China is popular due to its low mold costs, high capacity, and wide selection of foundries. China offers all casting methods under one roof: from high-pressure to lost-wax. Moreover, the material is often less expensive, and there are many options for subsequent processing such as machining and coating. For large series or complex castings, this is often the most cost-effective option.
By combining outsourcing with a strong supply chain, quality control and a clear working method, TOS ensures that aluminium castings meet all size, strength and finish requirements.
