ShopTALK: Mold Transfer Considerations Everyone Should Know

Valuable insights and tips from Ferriot’s engineering experts 

Making the decision to move injection molds from one supplier to another can be a daunting task, not for the faint of heart. The saying “the devil is in the details” is very apropos to the mold tool transferring process. If you don’t cover all the necessary details, you may be jumping from the frying pan into the fire. At Ferriot, we’ve identified seven key points you should consider before making a tool transfer, including everything from inventory to cosmetic standards. It takes communication, transparency, precision, and above all, experience. We hope these recommendations help you with a successful transition.

Before we proceed with our ShopTALK discussion, we recommend reviewing our whitepaper Mastering the Shift: 7 Key Points for Smooth Injection Molding Supplier Transitions. Our conversation with Jerry Graf and Amy Mathia will investigate some of these considerations.


Mold Transfer Consideration Talk

Jerry Graf  is the Manager of Engineering. Previously, we spoke with Jerry about how mold flow analysis and tool design impact injection molded part quality. Discussing mold tool transfer considerations is a natural extension to that conversation.

Amy Mathia has been with Ferriot for over seven years as an Engineering Project Manager who works closely with the customers, our tooling engineers, and the production department on new product development. One of Amy’s main goals is ensuring projects are within budget, and her experience includes some rather challenging mold tool transfers. 

Liz: In addition to the white paper that I mentioned earlier, how does Ferriot help customers feel comfortable that, when they transfer their mold to us, we can hit the ground running?  

Jerry: We use a checklist, a guide for transferring tools. Engineering also has an internal checklist that we would go through upon receipt of the tool to ensure it is clean, properly maintained, and ready for our production floor. It’s very similar to the checklist we would go through when we receive a new tool we built or had built for us. With the checklist, a prospect can go down the list and say, “Yeah, okay, I’ve got all of this lined up, so I now can proceed with a higher degree of confidence.”

Liz: Why might a mold owner want to stay with their current supplier? 

Amy: As we’ve learned about tooling problems, quality issues, and so on, we had to tell prospective customers, “Here are some of the headaches you’re going to have.” We don’t sugarcoat it because it can become expensive to correct these problems. 

Jerry: And it can go both ways. Because on the saes side, we’re interested in earning more transfer business, but on the engineering side, it (often) creates many, many headaches for us. So, when talking to a potential customer about clear and obvious issues, we must ask them, “why would they want to do it? Is it worth it? Why should they not want to do it? What are the options?

Liz: So, it is important to know ALL the “why’s” when it comes to a pending transfer?

Jerry: Yes, that is one of the critical questions. Making sure we’re talking about some of the (possible) headaches, one of the key questions to ask when taking on a transfer tool is, “Why are you transferring it?” More often than not, it’s because they’re having trouble with it.

Liz: And what kind of trouble are they having?

Jerry: Frankly, if a customer transfers the trouble, that’s moving it to a different spot; it isn’t solving the problem. So, we need to have a frank, open, and honest discussion about what is wrong. Why are you (really) transferring it? Why do you want to transfer it?

Liz: After you find that out, do you ever say, “Well, you probably shouldn’t transfer because we may not have the answer for you.” Or do you confer amongst the engineers at Ferriot for a solution?

Jerry: After assessing the situation, once we know the problem or problems, we often tell them, “Well, yeah, we can help you with that. We can help resolve that situation. And here’s what getting this mold into the proper shape will cost.”  

Another bad reason to move it is that the tool is old and worn out, and your current supplier can’t provide quality and can’t maintain production. But if the tool is old and worn out, neither can we. If there’s something wrong with the tools, that must be taken into consideration either before it’s transferred or as it’s being transferred. 

Liz: What are some good reasons to do a mold tool transfer?

Jerry: A good reason for moving a tool would be you’re moving it for logistical reasons. For example, you’re getting it closer to where it needs to be from a manufacturing or distribution perspective, so you’re not shipping the finished product so far. Or you’re moving it to a supplier with superior capabilities to run the part. 

Amy: To be perfectly honest, I’m not a big fan of transfer tooling. It’s okay to be blunt about it. Typically, the reason is it’s a problem somewhere else, and our customers want to move that problem. And when our biggest customers ask us if they can do that, we can’t say no. However, one of the best reasons I have heard of in my experience for moving tools to Ferriot would be the value-added things we can do here—for example, painting parts. If a mold owner has a part being molded by another supplier, and then they must send the parts somewhere else to get painted, additional costs are obviously involved. So, one good reason for transferring to Ferriot is that we also print and paint parts. Those are just two of the value-added things that we do. But in general, when someone is looking to transfer tooling, it’s a problem somewhere. Tools aren’t being moved because everything is running beautifully. It just doesn’t happen that way.

Liz: Yeah. Like Jerry said earlier, they’re just looking to move the problem and that’s not always a solution. However, we can work with them to find a solution.

Amy: Absolutely. Another thing that could be a good and a bad reason is capacity. Your current molder might not have the capacity, and you might find a molder that has the capacity and can speed up your lead times.

Jerry: Yes. That would be another good reason to move the tool. It is a reason that would not be necessarily problematic if you’re looking for a supplier that has additional capacity, additional capabilities of any sort, as Amy mentioned, finishing capabilities, capacity capabilities, maybe some processes that your current supplier doesn’t have because they’re more of a shoot-and-ship shop. And just trying to consolidate that all in one place. Those are reasonable reasons to want to move the tool. 

Liz: With the recent increases in fuel costs, are you seeing people interested in transferring molds because of the shipping costs?

Jerry: Yes. We’re seeing customers bringing tools here from Asia because of the problems of getting parts across the ocean. They’re re-shoring some tools into North America.  

In part two of this article, I’ll review addition tool transfer considerations as well as a few mold tool transfer success stories with our team of experts. We will discuss some challenges that we faced with our customers, how we addressed those challenges, and the end results that Ferriot’s solutions delivered.

5 Things No One Will Tell You About Custom Injection Molding

CAD modeling software and 3-D printing has sped up new product development and enabled all kinds of people to transition their concept from the whiteboard or the cocktail napkin to a tangible piece that they can test. Once the prototype phase is complete, the focus turns to making the product manufacturable in volume and one of the common manufacturing methods is injection molding. But injection molding has design requirements that differ from other prototyping methods. 

After having spent so much time developing the concept, going backwards in the design phase to accommodate injection molding can be frustrating. AIM’s goal is to always position ourselves as a thoroughly transparent company in our industry. Because of that, we have put together a selection of custom injection molding topics that can help prepare you for what’s ahead. If you are interested in learning more about our industry, we invite you to read on: 

CAD models only show cosmetically perfect parts

The renderings in your CAD software shows the perfect part. It’s flat if you want it flat, round if you want it round. It’s thick if you want it thick. The surface is smooth and without flow lines or gate blush. No mold parting line or flash.  No burn marks from superheated air that is trapped into the tool. It is every bit as flawless as you imagined.

This is not to say that injection molding can’t help you achieve the part as you imagine. But your injection molder should have a thorough design discussion with you to ensure that the tool, the most expensive part of the process, is built to your expectations. Discovering a requirement after the tool is built could mean starting over, which is as financially painful as it is devastating to your schedule. Luckily for our customers, AIM is a leading expert in the industry, meaning that we have a thorough understanding of these types of mistakes and have a process in place to avoid these pitfalls of manufacturing.

Not all tools are equal

There are different classes of tools, aligned with their required longevity, and they have different build standards. That can be tough to distinguish, because it ultimately comes down to “craftsmanship” which is hard to distinguish in person and impossible to see in an emailed quote. Obtaining a quick-turn tool does you little good if you plan to go into production and it falls apart in month 2 because too many corners were cut. A budget tool may save you $, but what if you have to rebuild it in 6 months because there is flash everywhere? This can make it difficult to compare vendors and quotes, particularly if you are just starting out and don’t have a lot of experience. Commonly, simple cost can be a tempting metric for vendor evaluation, but it might not always be the best choice for you in the long run.

AIM Processing doesn’t build tools in-house.  Instead, it works with a variety of domestic and offshore toolmakers to help build the tool that is best for your needs: budget, timing, durability, and precision.  We think this is a better model for our customers.

Thicker isn’t always better

When starting out with a new plastic project, people are often looking for some level of rigidity. The common solution is to throw more plastic at it and make it thicker. That can work in some cases, but it isn’t always the best solution. Thicker parts consume more plastic volume, which increases cost. Thicker parts take longer to cool, which extends the cycle time, reduces output per hour, and increases cost. Further, areas of thick and thin in a part can create issues with sinks in thick sections and shorts in thin sections.

Instead of a thicker cover, consider making the wall thickness thinner and adding ribs on the inside. This has the benefit of reducing plastic volume and cycle time, which leads to a product that is just as strong but costs less. AIM Processing has experience with hundreds of enclosures and can help with design guidelines to make your part strong.

Don’t let your plastic choice put you in a corner

There are well over 100,000 grades of plastic resin for a reason: they are different. Some are better for chemical resistance, electrical resistance, flame/burn resistance. Some hold their dimensions more consistently. Some are suitable for medical/food environments. Some are suitable for high temperature exposure. Some are more UV resistant. Lastly, some cost less. When you are developing a product, the performance of the plastic may be the last thing you’re thinking about. So, you might be thinking, no big deal – we could just switch later.

Plastics shrink at different rates, so this means that a tool designed for one material can give you a different sized part if you change materials. Some plastic families will have similar shrink rates as others. But if you suddenly discover you have a chemical resistance problem, you might find that you don’t have similar shrink-rate, chemical-resistance plastics to choose from. Different plastics may have different tool draft requirements.  If you’re at this point, you might need to remake your tool.

It is for this reason that it is crucial to work with a molding company that has a thorough understanding of the molding attributes of a wide variety of plastics. However, even with a highly knowledgeable manufacturer, changing mold designs to accommodate material changes mid-production will typically result in additional costs and longer production times, so it can be beneficial to discuss project details extensively with your custom injection molding partner before the full production run begins.

3-D printing can make some pretty impossible parts

Injection molding has a few design aspects that differ from 3-D printing. Injection molding generally involves a tool or mold that is held closed under pressure while plastic is injected into the tool. When the cycle is complete, the mold splits open with one moving side, the part is ejected, and the cycle repeats. To make this magic happen, the part can have undercuts or side holes, but those require features that must move out of the way. This is possible, but it can increase tooling cost and they must be designed for your needs. Another requirement for injection molding is draft. When the part is ejected from the moving side of the tool, draft is what enables the part to move cleanly off the tool. Being aware of these differences can help you make the transition to injection molding.

Injection molding does have some guidelines that differ from 3-D printing, but they are fairly simple.  If you’ve made it this far, you’re close.  Let AIM Processing help you move from your concept or prototype to production.
