How do you control quality and can you provide testing reports?

For custom metal parts, the sample cycle is generally 30-40 working days, but the final lead time also depends on the complexity of the product and the chosen manufacturing process.
The delivery time of bulk goods varies depending on the orders quantities and processing procedures. We will provide a formal and accurate schedule when placing an order. If the project is urgent, please inform us in advance and we will evaluate and reserve the production capacity for you.

For metal parts, we supply carbon steel, alloy steel such as 40Cr,42CrMo,16MnCr5, stainless steel, cast iron etc. For chains, common materials are carbon steel alloy for heavy-duty transmission, stainless steel for corrosionresistant working conditions.

Yes, custom manufacturing is our core business. We can work from your 2D drawings, 3D files or physical samples. Our engineering team will review dimensions, material requirements and tolerances first, and supply manufacturability suggestions to you before quotation. We support various processes including casting, forging, machining and heat treatment for metal parts, as well as customized chain with special pitch, material and surface treatment.

Sure. Please send us your product drawings (2D and 3D). Then, our engineers will do technical analysis and drawings evaluation. We will let you know whether it is suitable for permanent mold casting, or provide feasible technical proposals.

Many aluminum alloys are suitable for permanent mold casting. Especially, aluminum-silicon (Al-Si) alloys are the most widely used due to their outstanding casting and mechanical properties. Common representative grades include ZL101 / ZL101A and ZL102.

Permanent mold casting is suitable for high-volume production of small to medium-sized non-ferrous (especially aluminum alloy) castings. It offers significant advantages when customers have high requirements on dimensional precision, surface quality, and internal density. For example, intake manifolds, transmission housings, elevator brackets, machine bases, and other industrial structural components can be made by this process normally.
