Choosing a Sheet Metal Contract Manufacturer: In-House Finishing vs. Outsourced Powder Coating

Highlights 

There are a few key differences between in-house finishing and outsourced powder coating. In-house finishing requires a high investment for land, equipment, labor, maintenance, and safety equipment. However, its cost is low in long-term production goals. In the sourcing process of custom Chinese sheet metal parts, you have to look at every factor.

On the other end, outsourced powder coating is cost-effective since it does not need any of those elements, unlike in-house finishing. It is suitable for businesses that need short-term objectives for sheet metal parts. The lead time is higher, and the quality control and consistency are low.

If you are among those who either want to manufacture or outsource the sheet metal parts, this blog is for you. It will help you decide whether to go with in-house finishing or outsourced powder coating for the best outcomes. 

What are the Pros and Cons of In-House Finishing?

There are some primary and some secondary benefits of in-house finishing. The first is complete control over the production process, where there is no outsider. It means everything is your own, and you can finish as per your requirements. Then comes a shorter lead time than an outsourced alternative. Here are all the pros and cons that will help you select the option better.

There is Complete Control over Production

Since a sheet metal manufacturer has complete control, it can change anything it wants. Whether it is about increasing or decreasing the units or quality, in-house finishing provides a wide span of control. This is where such manufacturers also work on custom aluminum metal enclosures. Since they have full control, they can do as much customization as well as finishing as they want. Such control allows a sheet manufacturer to get full independence on finishing operations. 

Manufacturers Get Lower Operational Cost in Long-Term Process 

When we look at China custom sheet metal parts, they are much cheaper than most alternatives. The reason is the much lower operational cost. It happens when a manufacturer has maturity in production, and that leads to better control of cost. A China metal parts manufacturer who has lots of experience in production knows how to reach a cost-effective mode of finishing. Both production and finishing processes are very cost-effective. Although the initial cost is high compared to outsourcing, its long-term benefits are high. Slowly, a manufacturer learns how to control the cost by reducing unnecessary steps and their costs.

There is a Need for High Initial Investment 

Initial investment is the biggest difference between in-house finishing and outsourced powder coating. One has to bear the cost of a production facility, spray guns, laborers, ovens, and every mandatory supportive element. The capital has to be there that can bear a massive initial cost. So, if a business is looking for long-term metal sheet finishing operations, they need to prepare themselves for a high investment.  

Have to Bear Preparation, Training, Process, and Overhead Costs

Then come secondary factors that are site preparation and training of laborers. These two factors are very costly, and they take some time. The finishing process is long and costly when overhead costs are included in it. This is another major burden on any sheet metal manufacturer who goes for in-house finishing. Safety equipment, maintenance, ventilation, and some other factors also include extra costs. So, there are lots of additional costs that slowly increase the final cost of in-house finishing. 

However, in long-term missions, these costs drop when manufacturers improve their processes. They work on a lean production process, which affects the per-unit cost. 

What are Pros and Cons of Outsourced Powder Coating?

Then we have the other half of this comparison. It is about outsourced powder coating. Some China metal parts manufacturers offer this service to businesses that can not afford high facilities and labor costs. There are some more factors that show the pros and cons of outsourcing the powder coating. Sheet metal coating becomes a cost-effective solution for many companies, which also includes flexibility of orders. However, there are some disadvantages also, and you will find them here.

There are No Labor, Equipment, and Maintenance Costs, But Only Per Unit Cost 

The core difference between an in-house and outsourced sheet metal coating is the per-unit cost. Yes, in most cases, the per-unit cost in outsourced powder coating is less than the in-house method. It is suitable for those who have short-term objectives. An outsourced powder coating method has no maintenance cost either. There are no labor, facilities, equipment, or safety needs. That means China custom sheet metal parts’ powder coating will be cost-effective for many companies.

It is a Flexible Solution with High Scalability and No Fixed Overhead Cost 

The scalability is high in outsourced powder coating. Industries increase and decrease the size and quality of orders as per their need. They do not have to bear extra overhead cost when the production size is small. Industries that have to face low demands in some months of the year do not have to face high overhead costs on production of low units. All they do is use an outsourced method along with customization for a low-cost powder coating process. A China metal parts manufacturer that has such a powder coating service can help such industries. Those industries will not have to face fixed overhead costs when the production of specific sheet metal parts is paused. An outsourced powder coating provides high flexibility to small and medium businesses.

There is a Problem, Which is a Higher Lead Time

However, there is a problem with outsourced powder coating. It is about higher lead time. Industries have to wait for a long lead time even if the order is not very large. It happens because mega manufacturers provide outsourcing services, and their production size is massive. This is why it is not possible for anyone to get a fast lead time even if the order is small. The production size caters to all buyers, from small to large orders. In this way. Someone who has a small order size has to wait for long lead times because the main production takes more time than expected. 

Limited Control on Coating Process and Quality Assurance

Then comes the most challenging factor for industries that take this option. Outsourced powder coating gives limited control to any industrial buyer. That means whoever chooses this method will not be able to have much control over whether it is in production or in quality assurance. 

As a result, there is a massive risk of quality inconsistency. For instance, every time you choose a supplier for outsourced powder coating, they may not provide you the exact same quality every time. There will surely be some differences between the previous and current sheet metal surfaces. When someone coats in their own facility, that manufacturer has full control to maintain the quality. This is why businesses that want to go for long-term objectives in steel metal production have to be very careful in surface quality.  

Conclusion

There is a vast difference in the outcomes when one chooses in-house finishing and outsourced powder coating. These two methods provide some pros and cons that surely affect the cost of companies that deal with sheet metal parts. Usually, small and medium-sized companies go for outsourced powder coating, which does not require any facility, equipment, labor, or maintenance costs. They simply choose a manufacturer and get the work done. 

However, the lead time is longer, and the control on quality is very limited. On the other hand, an in-house finishing service requires massive initial investment and lots of costs, but it gives full authority, control, and cost-effective results after some time.

Frequently Asked Questions

How to Decide If In-House Finishing or Outsource Power Coating is Better?

It all depends on the budget, production objectives, and quality targets. If someone wants to have consistent quality for long-term projects, it is better to have in-house finishing, but it requires a massive budget. If someone wants short-term objectives at low cost, it is better to choose outsourced powder coating. Such objectives are achievable through a sheet metal contract manufacturer like DongGuan JianZhao Metal Plastic Co., Ltd.
