Outsourcing Metal Stamping Dies

Metal stamping companies outsource tooling and dies for many reasons. Sometimes it is a matter of the tool and die shop being short-handed or facing a backlog of orders. For others, it is a matter of reducing costs and improving customer relationships through better turnaround time and increased capacity as part of an emerging or existing business strategy.

Whatever the reason, outsourcing is not a fail-safe strategy. To avoid the many variables, companies must start with a make-or-buy study that evaluates their internal capabilities using answers to the following.

Design and Engineering

Does the project require you to have die designers and engineers with varied experiences? Does the project require unique process engineering skills? Does your engineering department have the full range of capabilities and design tools, including CAD, CAM and CAE tools required for the project? Does the complexity of the project require intensive communication with internal management, manufacturing, engineering and quality disciplines? Does your company have experienced project managers that can effectively communicate with internal and external customers and other outside sources?

Cost, Price and Delivery

Are your fully allocated fixed and variable costs higher than outside supplier costs? Would your internal marginal costs be lower or higher using an outside supplier? Are the overhead costs associated with your in-house processes lower? Are your labor rates lower internally? Can you purchase raw materials at a lower cost than your supplier? Is your inhouse operation competitive in delivery, service, quality and price?

Other Considerations

Regardless of your reason(s) to outsource, requirements include proper planning, sound execution and resolute follow-up. All of these have costs associated with them. Airfare, car rentals, hotel bills and meals can add up quickly, especially if the project develops problems. Depending on your supplier’s location, in-bound freight, taxes and duties can offset any perceived savings, not to mention transportation time. 

You may have projects that would not be advisable to outsource. Products or processes that are part of a core business activity or those based on intellectual property would be two examples. Customers that specifically require you to have inhouse capability and capacity would be another reason not to outsource.

Developing a Supply Base

If you do not have a supply base, establishing and developing one takes considerable time to accomplish. Primarily, look for companies that have experience in your specific industry. Just because someone has extensive deep drawing experience with automotive panels does not mean they can build tooling for a stainless steel double-basin kitchen sink or a titanium aerospace product.

Reputation and references are reliable ways to find qualified sources. Ask for references. Find out what customers say about their quality, integrity, past performance and craftsmanship. Ask how well they handle short delivery and emergency programs. Do they have strong program managers? What types of products and tooling designs do they specialize in?

Visit their facility to determine if they have the support services you require, such as process modeling, surface strain analysis, CMM and inspection capability and laser scanning. What about reverse-engineering capabilities? Will you need them? Are their tryout presses high quality and the appropriate size and type for your work? Do the presses have feed lines for progressive- and transfer-die tryouts?

Evaluate how well staffed their engineering department is and whether you will you have a dedicated program manager. Is all of the engineering done onsite or do they outsource? If so, from where? If you have a need for 3D die design, do they have such capabilities? Are services and supplies such as foundries, tool steel suppliers, heat treating, plating and coating readily available?

Look for tooling suppliers that are cooperative and proactive in addressing problems. Insist that they be part of a team dedicated to continuously improving the design, manufacturing, assembly and serviceability of your dies. Your supplier(s) should be committed to building good relationships with your organization through continuous and cooperative communication.

A qualified supply base should consist of no more than three or four suppliers. When your suppliers know they only have two or three competitors, they can do a better job of cost estimating because each company understands that it has roughly a 33-percent chance of winning your business. When you have six or eight die shops bidding the same job, each may have less than a 15-percent chance of winning your business. When a supplier’s proposal department becomes busy, more attention is devoted to the potential business with a 33-percent opportunity than another offering 15 percent or less. 

Finally, do not rely on your supply base to be your estimating department. The chances of receiving accurate quotes diminish dramatically for unsecured jobs. It is not uncommon to see pricing vary by 50, 100, or even 200 percent between suppliers. The reason for this disparity is quite simple: If your company is bidding a job against five other competitors, the likelihood of you winning that business is one-in-five, or 20 percent. Your four tooling suppliers have a one-in-four chance to win the business from you, providing you get the job. The bottom line for your tool supplier: This is a 5-percent opportunity at best. You eventually may receive a tooling quote but only after those opportunities with a 33 to 50-percent chance get their proper attention. MF

Estimating your tooling costs inhouse is a better solution. Need help? Consider attending PMA’s Estimating Metal Stamping Dies and Parts, October 22-23, 2019 in Cleveland, OH. Contact Marianne Sichi at msichi@pma.org for more information or to register.
