Q: Do you have a Technical Adviser?
A:

At Hendrick, we provide a team approach to product expertise.  Our experienced sales and customer service staff are available to help our customers with most perforating and fabrication solutions.  In more complex situations, our engineering staff can assist.  We also work with our manufacturing process experts to assure that all requirements are met.

Q: Do you offer Design for Manufacturing (DFM)?
A:

Hendrick's engineering and manufacturing team will review your design with the goal of optimizing your design for efficient manufacturing and potential cost savings.  This starts with the requirements in the CAD file--making sure that it can be manufactured as designed.  Our team understands how metals perform when being perforated or fabricated and can make suggestions if they anticipate any perforating issues with the desired material.  Finally, they will review the tolerances to be sure they are within our standards and to ensure the part is made correctly.

Q: Do you perforate custom designs?
A:

With hundreds of high-speed perforating tools available, Hendrick can readily produce most hole pattern designs.  For unique requests, our in-house tooling department can build a tool and punches to manufacture the pattern.  We can also produce custom designs with our 8kW fiber laser or our high-speed CNC punch presses.

Q: Do you provide finishing such as paint, powder coat, chrome, etc?
A:

Hendrick maintains a relationship with preferred suppliers to provide surface finishing to manufactured parts. Whether you require powder coating, chrome plating, anodizing, or silk screening, we can deliver high-quality finished components.

Visit  our finishing page for a complete list of available options and their uses.  

Q: Do you stock raw material?
A:

 In order to provide shorter lead times and competitive pricing, Hendrick maintains a large inventory of popular materials in both sheet and coil form. 

Q: I would like to give you a blanket order.  Can you hold finished parts for release?
A:

Q: In addition to perforating, do you do other fabrication?
A:

Hendrick offers a broad range of fabrication capabilities including bending/forming, punching, laser cutting and welding.  Fabrication can be done as standard sheet metal fabrication or as a value-add to our perforated products.  For a complete list of services visit our Fabricating page or download our Facility List.

Q: Is there a minimum quantity I have to purchase?
A:

Hendrick does not have a minimum quantity for orders.  

Q: What is the lightest to heaviest gauge you can perforate?
A:

Generally, we perforate .002" to 0.75". There are different machine operations used to perforate materials.   Our all-across high-speed perforating is capable of punching up to 0.25", our CNC punch presses go up to 0.375" and our newest 8kW laser can go up to 1.5".  Of course, these gauges are dependent on the type of material being perforated.

Q: What is your standard flatness tolerance?
A:

The standard flatness tolerance is dependant on the material and its thickness. Hendrick has developed a technical resource that explains flatness and defines the standards. Download standard.

Q: What is your standard lead time?
A:

Standard delivery is 2-3 weeks from print approval.  Exceptions may occur due to the complexity of your product or delivery quantity.  If there is an exception, Hendrick would discuss this with you during the quoting stage of your order.

Q: What kind of lubrications are used in your perforating process? Will the material be oil-free when delivered?
A:

Our all-across, high-speed perforating requires lubrication during the manufacturing process.  The type of lubrication varies, based on the material.  If lubrication is a concern, please discuss this with your sales person. 

Hendrick does offer in-house spray degreasing to clean residual lubricants.  This is especially useful when the material will undergo further finishing treatment such as powder coating.  Be sure to discuss your requirements during the quoting process.
