Frequently Asked Questions
Frequently Asked Questions (FAQs) – Your Guide to Precision Manufacturing Solutions How much will this part cost? And the answer is …………. it depends on the following: Quantity per run, the state of your drawings, type of material, number of finishes and fasteners, tolerances you have asked for, workmanship expectations, do you want it yesterday?, …
Comparison of Processes
What process is better; laser cutting, waterjet cutting, CNC punching, or metal stamping? Each process has its strengths and limitations in terms of cost, edge quality and accuracy. The manufacurers of the equipment often downplay the limitations which can include nibble marks, dross, scratching, taper, oxidization, scaling, burrs, speed and finish quality. We will recommend the best process to you …
Trumpf Punch Presses
Trumpf Punch Presses Download our Trumpf Tooling List here. We have three CNC punch presses which are programmed using Trumpf’s 3D modelling and tool-path software. The Trumpf machines use an integrated linear tool magazine on a rail that accepts pre-aligned tool cartridges. Off-line tool alignment almost eliminates the tool alignment set-up downtime that turret style punch presses inevitably …

Trumpf Tooling List It is often useful to design around a tooling list. We have two .pdf tooling lists and an older Excel tooling list. Call us if you need help! We have a REGULAR TOOL LIST and an CUSTOM TOOL LIST – both are in PDF format. Here is a list that combines both REGULAR …
Sheet Metal Design Guidelines
Sheet Metal Design Guidelines Views Create clear, uncluttered views that completely detail the part Use third angle orthographic projections Use a minimum of three views (front, top, side), isometric view with hidden lines removed will add clarity Provide detail views as required if it will avoid crowding, or if it will make an otherwise ambiguous …
Welding Symbols
Welding Symbols Most of the welding done at Hansen Industries is Microwire (MIG) welding. Tungsten (TIG) welding is a slower process, but in some cases it may be required. If an aluminum part is to have a clear finish, the welds need to be the same colour as the rest of the part. TIG welded …
CAD Tips
For those who are in the design departments this section contains a few tips on improving graphical communication. Our main concern is that a drawing contains all of the necessary information to construct the part. Clear and accurate drawings help ensure that each customer gets the product they are expecting. An analysis of previous nonconformance, …
Self Clinching Fasteners
Self-clinching fasteners provide strong, quality threads in metal and P.C. boards too thin to be tapped. Broadly defined, a self-clinching fastener is any device, usually threaded, that, when pressed into ductile metal, displaces the host material around the mounting hole, causing it to cold flow into a specially designed annular recess in the shank or …
Bend Allowance
When designing a three dimensional part sheet metal part, it is important to take into account the bend allowance (also known as bend deduction). When bending a sheet metal part in a brake press, the region of the sheet close to and in touch with the punch and die stretches and compresses. Thus, if you …
