Do you have any minimum volume requirements?
CGI’s investment in automation allows us to provide short lead times for production volumes. When the set up cost is amortized over the volumes run, this may drive up the pricing of smaller quantity production jobs. Because of this, CGI typically has production runs exceeding 250 units. Quite often, these volumes are significantly higher. This is not a firm rule, as other factors can play a role, such as the size and assembly of the sheet metal parts required.

Do you work with tubing?
CGI is able to weld tubing to fabricated sheet metal components. We do not have the capabilities internally to manufacture tubing in production quantities.

Do you work with wire?
CGI does not have the necessary equipment to manufacture wire components or assemblies. Our equipment is very specific to sheet metal fabrication.

Do you do machining work?
CGI can provide machining services by outsourcing to a machining company that is very experienced and cost effective. CGI’s expertise and competitive advantage is in sheet metal fabrication.

What is your sample or prototype policy?
CGI provides sheet metal fabricated components and assemblies across a number of different industries. Certain industries seem to require more samples and prototypes to be produced. We feel it is unfair to burden all the industries we serve with the overhead cost of preparing prototypes, therefore CGI does charge for prototype manufacturing. The cost for prototypes attempts to cover CGI’s direct cost.
There may be a need to review a first article prior to a volume production run. Sometimes these parts are provided for approval and do not have the complete finishing requirements (painting, plating, etc.). Typically there would not be a charge for providing this pre-production sample for approval. We can discuss the particular circumstances with our customer. CGI is very fair in our sample/prototype policy.

Do you powder coat finish in house?
CGI outsources our powder coating requirements. We utilize a very reputable finisher in the area that is at our facility daily delivering finished sheet metal components and assemblies.

Do you provide the stock raw material for production?
CGI maintains a minimum level of stock material for the majority of our sheet metal fabrication services. We typically order raw material cut to a specific size to maximize the material utilization and minimize waste in our fabrication process.

Do you work with customer supplied material?
We do manufacture utilizing customer supplied material, however we would need to discuss the specific application before committing to using outside material.

Common Technical Questions:

What information do you need to provide a quote?
In order for CGI to provide a quote for your sheet metal fabrication needs, we would need a drawing submitted with your quantity requirements. We can accept almost any format but prefer .dxf, .dwg or .pdf formats. These drawings can be faxed (708-780-6028) or e-mailed (cgi@cgimfg.com) for pricing.

What tolerances can you hold?
Shearing +/- 0.032
Punching +/- 0.005
Laser Cutting +/- 0.002
Forming +/- 0.015

What factors do you look at when deciding whether to laser cut or punch a part?
The geometry of the sheet metal part to be manufactured typically determines whether the part is best suited for laser cutting or CNC punching. Special tools needed to run in the CNC turrets can be eliminated if utilizing laser cutting, although laser cutting may require more machine time and possibly more cost. These special tools may be justified if the production volumes are high. Sometimes finishing restrictions necessitate the use of the laser or the CNC punch. In all circumstances, CGI would quote the lowest overall cost for production, given the specifics of the part to be manufactured.

What is CGI’s Commitment to Quality?
CGI has a Quality Program in place to produce sheet metal components and assemblies to our customers’ specifications. We would be happy to provide additional specific information as required.

Do you warranty your work?
CGI produces sheet metal fabricated parts according to drawings and specifications provided by our customers. We provide a limited warranty for a period of twelve months after receipt of your product. We can provide a copy of this Limited Warranty at your request.

Common Order Processing Questions:

What information do you need to process an order?
In order for CGI to process your sheet metal fabrication purchase order, we need to have a purchase order faxed (708-780-6028) or e-mailed (cgi@cgimfg.com). Included on your purchase order should be your billing address, shipping address, part number(s) ordered including revision code if applicable, quantity ordered per part, requested ship date, and any special finishing requirements. We may ask for a current drawing of the part(s) ordered. If this is the first sheet metal production order for your company, we will request a credit application to be filled out and we will promptly notify you of your credit status. We will acknowledge receipt of your purchase order and confirm the delivery date within 24 hours of receiving a purchase order form your company.

How do you process blanket orders?
CGI can work with a variety of systems in expediting orders. Some of our customers utilize KanBan releases, some require us to log into their websites for purchase order releases, others release via their own internal processing system. Blanket orders typically are for annual requirements of sheet metal components and assemblies. The release dates can be communicated by the customer for the entire term of the order but they don’t need to be determined at the front end. When CGI receives a blanket purchase order, we communicate with our customer to determine what their release quantity will typically be and we agree upon a safety stock quantity that will be available immediately after a release. Customers are notified of our lead time to replenish stock inventory so that they can adjust their quantities accordingly.

What is your return policy?
CGI produces sheet metal fabricated parts according to customer drawings and specifications. We produce these parts only when we have a purchase order. Since each order is customer specific and we have no other market to sell these items, CGI cannot accept returned items unless the parts do not conform to customer specifications. If that should occur, CGI will rework or replace the nonconforming parts. CGI will need to be contacted prior to returning parts so that we can assign a Return Material Authorization Number (RMA#). We may only want to have a small sampling of parts returned to make our assessment. Once we receive the items, we will notify you how and when we will provide parts that meet your specifications.


Common Administrative Questions:

What are your payment terms?
CGI’s payment terms are 1/2% 10, Net 30. Variations to these payment terms would need to be discussed and approved by CGI prior to fabricating your sheet metal requirements. CGI is able to accept credit card payments at our customer’s request or to get an initial production order shipped while awaiting credit approval.

What information is needed to set up a credit account?
A Credit Application needs to be completed, requesting basic company information, vendor references and bank information. We also request a Certificate of Resale Form (Illinois Department of Revenue Form CRT-61) along with a copy of the Resale Certificate. It takes approximately one week to process credit applications, depending on the timeliness of vendor responses. We will notify applicants of their credit approval as soon as it is processed.
