Cost Factors
Part Size and Shape
The size and shape of your parts matter a lot for cost. Bigger parts need more power and take longer to finish. This makes them cost more. Parts with deep holes or sharp corners are harder to work on. These tricky shapes need special care and can raise the price. If your parts are thin or delicate, workers must be careful. This helps avoid damage but also adds to the cost.
Geometric Feature | Cost Impact Description |
|---|---|
Internal channels | Need special tools and take more time, so they cost more. |
Blind holes | Make finishing harder, which increases the price. |
Sharp corners and edges | Hard to finish evenly, so workers may need to do it by hand. |
Varying surface angles | Make coatings or treatments uneven, raising costs. |
Mixed material sections | Need masking and extra steps, making things more complex and expensive. |
Delicate or thin features | Can get damaged easily, so careful handling is needed. |
Multiple complexity factors | Can make finishing cost more than making the part, especially for high-quality jobs. |
Quantity and Batch Size
Ordering more parts at once saves money per piece. Big batches lower setup costs for each item. This makes electropolishing cheaper for large projects. If you only order a few parts, each one costs more. Think about batch size when planning your order to get the best deal.
Finish Type and Complexity
The finish you pick changes the price. Simple finishes are cheaper. If you want a shiny, mirror-like look, it costs more. Some finishes need extra steps like buffing or special treatments. These steps add to the total price. Smoother finishes help stop rust and keep things clean. This is important for food or medical uses.
Finish Type | Description | Cost Implication |
|---|---|---|
#1 | Hot-rolled and rough, not polished. | Low cost because there is no finishing. |
#2B | Dull and smooth from polished rollers. | Medium cost, no extra polishing. |
#2BA | Very shiny and bright from annealing. | Higher cost because of special process. |
#4 | Brushed finish, used in kitchens. | Medium cost and good for many uses. |
#7 | Shiny from buffing #4 finish. | Higher cost because of extra buffing. |
#8 | Mirror finish, very reflective. | Highest cost because it needs lots of polishing. |

Shipping and Handling
Shipping costs depend on where you live and how big your order is. Big or heavy parts cost more to send. Some suppliers give basic packaging, but special boxes or wrapping cost extra. If you order from another country, shipping costs are higher and you may pay customs fees. Always ask for a shipping price before you order. This helps you compare costs between suppliers.
Minimum Order Requirements
Suppliers usually have rules for the smallest order size. These rules help them pay for setup and chemicals. If your order is less than 500 kilograms, you pay more for each kilogram. Small orders cost more because setup costs cannot be shared. If you order more than 1,000 kilograms, you pay less per kilogram. Here is what you should know:
Orders under 500 kg: Higher price per kilogram
Orders over 1,000 kg: Lower price because of bigger orders
Small batches: Higher cost for each part
You can save money by putting small orders together into one big batch.
