Questions to ask on industry expertise & proven success

If a manufacturer has successfully fabricated a custom enclosure line in your industry, they understand common challenges and how to overcome them. Ideal custom sheet metal manufacturers know precisely where they can provide value and success because they have hands-on experience building the product. You can leverage this expertise to increase your speed to market and minimize surprises in the manufacturing process.

Market Knowledge:

• Are they manufacturing the latest products on the market?
• What is their market history as a custom fabricator?
• Can they provide examples?
• What types of metal they can work with?
• Can they meet the National Electrical Manufacturers Association (NEMA) standards?
• Can they meet the UL 50 standard for electrical enclosures?
• Do they hold a UL file?
• What initiatives do they take to stay ahead of the curve as a metal fabricator?
• Are they actively present at industry events?
• What is their presence with industry associations?
• How many years of engineering expertise do they have in-house?
• How many years of contract manufacturing expertise do they have in-house?

Current Customers:

Do they have customers like yourself? (This can be in terms of industry, specific product line, products with similar requirements, etc.)

Questions to ask on supply chain strength/ footprint

Footprint and supply chain strength are critical to product success. Fabricators should be able to not only meet forecasted demand but also be flexible to support new orders, increased demand and new shipping locations. It’s also about relationships. Efficient custom enclosure manufacturers have developed a streamlined process of coordinating activities with buyers and sellers within their supply chain. The significant difference between a managed supply chain and an unstructured one is focusing emphasis on trusted relationships. This streamlined process allows for better communication, pricing and more efficient coordination.

• Do they have manufacturing facilities to match your current and future footprint?
• How close are they to your markets (physical locations – centers)?
• Are they willing to invest in supporting the supply chain growth of their customers?
• Are they ahead of industry trends around your supply chain needs, such as tariffs?

Questions to ask on in-house capability

Many fabricators can handle custom enclosures to a certain threshold before they hit their tipping point, and this can negatively impact on-time delivery, installation dates and more. Capabilities go beyond manufacturing equipment and include in-house engineering capability to ensure the quality and reliability of the product. Flexibility:

• Do they add value beyond meeting your price expectations?
• Are they able to accommodate different product lines and demand schedules?
• How easy is it for them to implement design changes?
• Are they able to build prototypes?
• Are they willing to collaborate with your in-house team?

Quality:

• What standards do they follow? i.e., ISO Certification
• Do their quality standards align with your own?

Control of Production:

• What capabilities do they have in-house?
• Can they provide an equipment list?
• Do they have a focus on safety?
• Do they have an engineering team on staff to collaborate with manufacturing?

It’s essential to ask these questions upfront.

Starting the search for a custom enclosure fabricator can be challenging to navigate through the sea of options, and it is necessary to ask these questions upfront, as well as other non-negotiables your team has. The fabricators who fit your needs won’t be afraid to answer the tough questions.

Questions:
1)Does this custom enclosure design and/or any traditional enclosure require a UL/NEMA listing and/or IP rating sticker in order to be used for our designs? I have seen some of our competitors construct custom enclosures as part of their framework! (I.E. Schubert, Groninger, BluePrint Automation, Etc.)

2) Will such design pass a UL field evaluation?

I was hoping that someone could answer a quick question for me. We are a custom Automated Machinery Manufactuer, and I have a custom designed electrical enclosure (see attached) that we would like to use for both North America (UL) and European (CE) marked equipment. I am having trouble finding enclosure companies that are willing to manufacture such cabinets. We have plenty of Sheet Metal fabricators that can definitely build these enclosure but they do not have listing capabilities.Questions:1)Does this custom enclosure design and/or any traditional enclosure require a UL/NEMA listing and/or IP rating sticker in order to be used for our designs?

Why re-invent the wheel? Why would you spend resources in area that has nothing to do with the success, improvement and general functionality of the equipment it serves? What is the cost benefit? Manufacturers find that this is not a cost effective way to stay competitive, but focusing on the core of their business and farming out the peripheral solutions is. There would be many panel fabricators and control system integrators who would compete for this business and you won't even have to go overseas. (Oops, forgot you're already there....;-)Not to mention they would already be familiar with the overseas marketing and regulatory issues.
