each one is an opportunity to make more money and grow the business. Certainly, nobody on the production floor has any issues with prospects and customers sending inquiries for projects. More work means more pay for more years.
The only folk who cast a dubious and disdainful eye at an RFQ are those who must formulate the quote. This is understandable because so many requests begin life as half-baked, deadline-based cattle calls for “estimates.” Whether you are a moldmaker or a molder, how many times have you heard, “We don’t need an exact quote, a guesstimate will be fine — but we need it right away.” This scenario sounds reasonable until reality sets in.
Reality sets in a few weeks or months after you submit your rushed budgetary estimate. The proposal you submitted was as detailed as it could be based on the customer data. What we typically get is:
- The design isn’t final, but we still need a quote.
- There are geometry issues that will be addressed later.
- Don’t worry about draft or radiuses or exact gating locations.
- We only have a rough idea of projected annual volumes. So quote one-, two-, four- and eight-cavity molds.
- We might want to put a label or some kind of information in this area, so consider in-mold decorating, pad printing, heat transfer or engraving as a possibility. Unless you can just laser etch the part after molding. Include a cost for each.
- We’re not 100% on a material yet, but that shouldn’t matter much, you can always adjust for shrink.
Analyze Quoting Approach
We all know that if you don’t submit a proposal, you don’t have a shot, but the question remains: how should we quote? We can make realistic assumptions based on our experience. For example, we know based on the geometry presented that the production mold will benefit from a more sophisticated strategy for temperature control, so we add the cost of machining and materials for conformal-cooled inserts. We might want to consider steel selection as well. Have the other shops in the running done the same? If not, they will be several thousand dollars lower than you right out of the gate, even though your idea will reduce cycle time or improve part stability.
Did you identify any potentially challenging steel conditions? Should you address those and make design revision suggestions? Should you quote based on what you know or based on the information presented? Have you ever submitted a well-researched proposal where you and your team applied best design practices and your know-how only to find out that the customer went with Marv’s Tooling & Bait Supply because Marv came in at “half the price?”
Consider that the individual driving the RFQ event is often not the person deciding which source gets the work. Did the RFQ come with a fill-in-the-cells spreadsheet? In a quoting scenario where several prospective sources are involved, all your work may ultimately be judged by only two of those cells: final cost and lead time.
You likely noted in your accompanying email and through conversations with your contact that you are including an amount to cover a round of steel adjustments and an additional sampling event to address that challenging steel condition noted previously. However, that information is not on the spreadsheet. And what do you suppose the Procurement Director at the ABC Corporation knows about a challenging steel condition? That Procurement Director’s annual bonus is based on cost reductions that are backed by documentation. They get no credit for buying a robust tool design to enable productivity and ease of preventive maintenance.
Build the Mold Buyer Relationship
Whether you love requests for quotes or hate them, you have to deal with them and effectively manage and respond to them. It’s more complicated than “Get all the information you can.” We need to determine the nature of our relationship with the mold buyer.
Are the questions we ask and the insight we provide valued by customer engineering and procurement? Unless you know that the customer’s engineering department plays a significant role in decision-making, purchasing will not consider all suggested areas of improvement.
What is the background/technical wherewithal of the OEM contact? Is this a gatherer of emails and compiler of responses? Can they answer any technical questions? If the person with whom you are directly dealing doesn’t know what annual production volumes are, whether or not the company has a resin contract or a preferred hot runner supplier, and they have no idea what you mean by steel safe, there is a strong chance that your wisdom and design for manufacturing (DFM) time will fall on deaf ears.
Are we being compared to similarly capable sources of supply? This is based on the capability and experience of the customer’s engineering department. The smarter they are, the fewer tool shops they deal with. If they’re good, they know which shops to engage based on geometry, size, and lead time. They won’t even accept a proposal from Marv, no matter the price.
The best we can do is gain an understanding of the available project scope and develop a proposal based on how attractive that job and that customer is at that time. If you must submit your quote on a spreadsheet, and the spreadsheet consists of cells demanding your business information (hourly rates for design, labor, machining, material mark-up, margin), understand that price is the only thing that matters.
The OEM’s engineering department may desire and appreciate your design for manufacturing efforts, but your DFM input will not be acknowledged or valued by procurement. This approach encourages one to quote low and systematically charge as things progress and then stall throughout the build and sampling events.
Does this conversation after the first run of parts sound familiar?
Customer: “Why does the surface look like that?”
Moldmaker: “That’s sink. The features you designed on the other side are causing that. We can fix it, but the tool’s gotta go back to the shop!”
Who wants to run a business that way? You’re not misleading your customer, but you are allowing them to fail or struggle when you could have helped to prevent it. Do you point out design flaws before submission of your proposal? Do you price the job low to get it and then educate them on design improvements and charge for them? The relationship you have determines the course.
If you are among a pool of shops quoting a job, and they only look at your proposal’s final price, and lead time, your investment in supplying design best practices and improvements may be lost or given to their current low-cost solution. An existing customer that has a history of contributing to your revenue stream and performance should be given the benefit of your experience and intuition every step of the way.
The only absolute we have is to get as much information as we can, as early as we can, and document the gaps and the impact that the missing information has on your proposal. In the end, the laundry list of required quoting-related information is not complicated; it follows a logical progression. Ask these four questions:
What are the individual part’s size, shape, critical geometry and surfaces?
How many are needed annually and for how many years?
What type of plastic is required for it to do its job?
What is required after molding?
Buying a mold is a complex and sometimes tedious process, but a few rules can help make the process easier. They’re not written in stone, but you’ll find that to most moldmakers they are gospel.
Send an RFQ that is as detailed as you can make it. Don’t make themoldmaker guess what you want. Moldmakers are a lot of things, but mind-readers they’re not! Be specific about the type of mold, the number of cavities, the steel, expectations of mold life, and any guarantees you’ll need. If you aren’t certain about any of these items, get input from your moldmaker to help you determine exactly what type of mold is best for your requirements. The more detailed the RFQ, the more accurate the moldmaker’s quote will be.
Be honest about why you are requesting a quote. If you need a ballpark figure to submit to marketing, say so. But don’t ask for a complete engineering evaluation and quote, then casually mention it’s just a preliminary quote on a project that’s at least a year away. Or you’re just fishing. Quoting is time-consuming, and moldmakers want to spend their time quoting jobs that have good promise of becoming a reality soon.
Respect the intellectual property of the moldmaker. The knowledge and creativity a moldmaker has acquired are his or her intellectual property. Keep those ideas and suggestions confidential when going out for quote. If you choose another mold shop to do the work, don’t tell moldmaker “B”to make it the way moldmaker “A” suggested in his quote. Remember, moldmaker “B” didn’t quote it that way and may not understand why moldmaker “A” made that suggestion.
Consider the benefits of forming a true partnership with your moldmaker(s).Bring in
him or her early on your project for input; work with him in regard to costing goals and budgets; life of the project and part quantity expectations. Moldmakers don’t like being mushrooms! The best purchasing is done by those who truly know their suppliers and play as a team, openly and honestly, to the benefit of both companies.
Communicate with and solicit communication from your moldmaker on a regular basis. Many provide Gantt charts or other types of progress reports online, or provide online access to regularly posted updates. Knowing where the mold build stands and if it is on schedule is critical, so request scheduled information stands and if it is on schedule is critical, so request scheduled information
Make your payments on time per the agreement. Few moldmakers can afford to play banker, and building a mold entails many, sometimes large, up-front expenses on their part. There are a number of ways to approach the payment schedule, such as 30% down, 30% at half completion, 30% at completion, and 10% upon part approval and mold shipment. Different moldmakers have different plans, or will work with you on a payment schedule that is fair, equitable and will benefit both companies.
Changes to the part design can mean changes to the mold. Remember, the more changes you make during the mold build, the less likely you are to get a mold in the lead time or at the price quoted. Understand that when you require part design changes, it often leads to changes in the mold design, which can add both time and cost to the mold build.
Define up front when the mold is considered complete. When is a mold complete? That often determines when final payment is made. Is the mold complete upon approved part sample? Upon shipment? Usually a mold is complete when it is capable of producing a part according to specifications and dimensions on the part print. Most moldmakers will make small changes and tweaks to get the mold to spec to make the part according to print dimensions. A decision to make a change to the part, and consequently to the mold, after the part has met print specs doesn’t mean the mold isn’t finished. When the part meets print specifications and dimensions, the mold is complete. Changes are done via an ECO (engineering change order) and will be priced accordingly.
If it sounds too good to be true, it probably is.You may find a moldmaker who quotes very low prices on a job. Maybe he’s hungry, or maybe his overhead is low so he can price lower than other shops. However, any quote that comes in too low might not be the bargain is appears to be.
When purchasing a mold, it’s especially true that you get what you pay for. Your molded components are only as good as the mold they come from, so be sure your mold is optimum to mold the parts you need for the life of the program.
A good mold quote is much like many other facets of life. The quality of result is proportional to the amount of effort you put into them.
The whole purpose of the mold, is to make the plastic part. So the more the mold designer knows about the part design, the more accurate the resulting mold quotation will satisfy the request.
If the part information is in the form of a sketch with no selected resin or composite identified for manufacturing it, you will get a VERY ballpark mold and component quotation.
A drawing will get you a slightly better result.
A CAD file and the desired resin or composite, you receive a more accurate quotation.
A CAD file with a part optimized for molding with wall draft, identified radii or sharp edges, required surface finishes identified and wall thicknesses optimized, keep out cosmetic areas and acceptable locations for ejection pin marks or knit lines, an absence of or identified undercuts with an understanding that they will add features to the mold design and cost. A very accurate quotation.
All the previous AND an understanding of the component’s use environment, i.e. a Physical Design Requirements Specification for the lack of a better name will result in as accurate a quote you can get without having designed the part with us participating in your work.
As stated earlier, the more the mold designer knows, the better the resulting deliverables will be.
