When an industrial application requires a product that is not available in standard form, or the standard material is not suitable, custom metal products can be beneficial. But the attainment of the desired result is highly dependent on the clarity of the product specification prior to product manufacture. Dimensions, material grade, tolerances, surface requirements, production quantity and operating conditions can influence the final product. A properly written specification will provide manufacturers and suppliers with a better understanding of what the finished product must do.
Begin With the Application
The first step is to establish how the product is going to be utilized. The operating environment can impact almost all material and manufacturing decisions.
Where applicable, the temperature, pressure, chemical exposure, mechanical loads, wear and expected service life should be taken into consideration. Material properties of a component used in a high-temperature system can be quite different from those in a general mechanical assembly.
The starting point is the application, so that the specification is not based on a material that is familiar rather than what is needed for a specific application.
Choose the Appropriate Material
The material used should be based on the purpose of the component. The various metals and alloys offer a variety of strength, hardness, corrosion resistance, thermal stability, conductivity and machinability.
When businesses Buy Custom metal products, they should provide the preferred material grade whenever it is already established. If the grade has not been determined, suppliers may need information about the working environment and required performance to help identify suitable options.
Before production, the compatibility of the material with the manufacturing process should also be taken into account.
Define Dimensions and Tolerances
It is important to have dimensional information that is clearly understood for custom manufacturing. Drawings should include overall dimensions, hole locations, thicknesses, angles, and other characteristics that would impact the assembly or operation.
Tolerances are also of critical importance. Not all dimensions require a very close tolerance, and overly demanding tolerances can make manufacturing more difficult and expensive.
A practical specification should be used to differentiate between critical dimensions and those dimensions that can be manufactured within a normal manufacturing range.
Select the Right Fabrication Process
The shape, finish, tolerances and production costs may be affected by the manufacturing method. The processes involved can be cutting, forming, machining, welding, rolling or other fabrication processes, depending on the product.
Businesses need to take into account, when Buy Metal fabrication materials, whether the material will be used for a specific fabrication process. Certain metals might have particular cutting, forming, welding or machining requirements.
Avoiding a material that would cause unnecessary production problems can be achieved by discussing the desired process early on.
Consider Surface and Finishing Requirements
Any surface requirements which relate to function or appearance must be specified. The requirements for roughness, coating, polishing, plating or other finishing may need to be specified.
Surface condition may affect friction, wear, corrosion properties, sealing or interaction with other components in functional components.
If a specific finish is not a necessary requirement, it may be better to specify the purpose of the finish, and not the specific finishing process.
Account for Production Quantity
The number of units might affect the most efficient production method. If the quantities are small, you might be able to get away with a different process than a large production run, where tooling, set-up time, and repeatability are more important.
The buyers need to inform the quantity of orders they are placing and if they will be ordering again in the future.
This information can guide suppliers to suggest an approach to manufacturing that meets technical needs and has realistic production economics.
Provide Complete Technical Information
A good custom-product request should provide sufficient detail for the supplier to grasp the entirety of the request. Any technical drawings, material specifications, tolerances, quantity, finishing and application details can be helpful.
Lack of specification can cause re-questions, incorrect assumptions and delays in quoting and production.
In more complex products, it may also be useful to discuss the requirements directly with a technical supplier, as this can also help to identify details that may have been overlooked in the initial specification.
Conclusion
When it comes to specifying a custom metal product, it’s more than just a simple shape or metal name. All of these must be taken into account when applying the material, its properties, dimensions, tolerances, fabrication process, surface requirements and the quantity to be produced. Technical information is easily understood, providing a better basis for suppliers to make accurate quotations and to ensure standard production.
