Make Vs. Buy Conveying Systems
The decision to make or buy a conveying system relies on four main factors.
With a competitive, evolving global market place, changes in outsourcing and scarce availability of engineering talent, the decision to make or buy conveyors is one that many companies face every day.
For those integrators and OEMs that do choose to build their own conveyors, it can look like a smart choice. And in theory it seems like a money-saving idea:
- You’re already paying your employees.
- It’s less expensive to buy components.
- You have a better understanding of your needs.
- You have done it better.
When you dig deeper and look at all the issues associated with your conveyor system, the decision to make or buy becomes foggier as the cons outweigh the pros of building conveyors in-house. When factors such as production capacity, core strengths, repeatability and hidden expenses are added up, it’s likely more efficient — and a better value — to purchase your conveyors from a reputable supplier. Here are four factors to help you with your decision:
Production capacity centers on time. And time, as simple as it sounds, is perhaps the biggest factor that is often miscalculated. Although you are already paying your employees, the time spent working on building a conveyor is time that they could be designing, improving, expanding and manufacturing your current product. This includes time by the engineers designing, researching, modeling and creating a bill of materials for the conveyor, time spent by your purchasing department procuring the components, as well as time spent by production staff manufacturing, assembling, testing and debugging the conveyor. As many businesses continue to see growth and scarcity of engineering resources, the time that current employees spend away from your core product comes straight out of the bottom line.
Production capacity also includes space. Space in most facilities is at a premium, so creating and maintaining an area to develop, manufacture and test a conveyor takes away from your production output — not to mention the space required for storing excess components and inventory to support conveyors.
Typical manufacturing companies have engineers that can design a variety of components as needed, but conveyors are not a core strength for most.
A company that specializes in manufacturing conveyors has done the necessary research. It has examined a variety of both environments and applications and invested time and money in testing the product in different scenarios. It also can predict the types of issues that will come with various environments and use. A specialist in manufacturing conveyors is current with the latest technologies — including belting, gears, drives and controls. It has worked with component suppliers to get not only the best volume pricing, but to ensure high-quality components. Reputable conveyor manufacturers have completed all the necessary upfront work to build conveyors — work that a company looking to build in-house will have to accomplish.
Another item that can be considered a core strength for many is aesthetics and customer perception. All components on the equipment or machinery that bears your company’s name is a direct reflection on your business. The look and feel of the conveyor, as well as its dependability to run, can have a large impact on the customer’s overall impression and experience with your company.
Quality of the conveyor can also directly impact the quality of your product. A smooth-running conveyor not only shows well, it can protect products in process from start to finish. Scratched packaging, dented products and damaged materials can cost you money. A dependable conveyor fitted to an application will get your product from point A to point B safely and efficiently.
Finally, consider the service and support needed with installed conveyors. Conveyor manufactures have drawings, manuals, spare parts lists and the expertise required for preventive maintenance ready to be accessed.
Typical in-house fabrication is assigned to one employee who designs it for that exact application. If that person leaves, it can be difficult to find someone who can step in with the required knowledge to properly design and service the conveyors.
Training and documentation are usually limited, plus re-training can be difficult and costly. The ability to call a dependable conveyor supplier can significantly help reduce downtime. Repeatability is very dependent on documentation. From routine maintenance to installation instructions, spare parts lists and troubleshooting, proper documentation can save a lot of time and effort. When building in-house, the conveyor will often undergo several modifications during the design and manufacturing process.
Drawings don’t always get updated, parts lists aren’t created and manuals don’t exist — all of which can cause additional work in what can be very urgent downtime situations.
With any conveyor, wear parts or replacement parts are a necessity, and how quickly you are able to obtain these parts can be vital to keeping the line running. Conveyors made in-house most likely will have parts purchased from various suppliers.
If those suppliers discontinue making the parts needed as replacements, or even go out of business, you could be left scrambling to get the conveyors back in action. Conveyor manufacturers stay ahead of the curve with changes in components and can react quickly to your needs. They are prepared for emergency situations and can typically ship replacement parts as soon as the same day. This can save time and the hassle of trying to reengineer the product internally. They can also provide preventive maintenance training and parts auditing programs to make sure you’re ready in case issues arise.
With any project you need to account for hidden expenses — such as administrative costs. From processing a purchase order for each component in the conveyor to receiving and processing the parts into inventory, administrative costs can add up. Plus, there are shipping and logistical expenses to get the necessary materials, not to mention the time to manage, move and inventory all of these materials.
Changes can also contribute to hidden expenses. Starting with the design phase, changes can stem from vendor lead times and component changes to the product learning curve. In the manufacturing and installation process, design flaws, part problems, building obstacles and other unforeseen issues all contribute to last-minute changes — all of which result in delays and increased costs.
Another thing you’ll receive when buying a conveyor is a warranty. A good warranty can take the stress out of wondering if you’re purchasing a reliable product. It’s a guarantee from the manufacturer that the product is of good quality and construction. If it were to contain any manufacturing defects, a warranty provides you the right to ask the manufacturer to deal with those issues.
All of the above scenarios involve costs that can impact the overall bottom line of the company and have lasting effects on the production and quality of your core product. Ultimately, the decision to make or buy boils down to what’s in the best interest for each company.
