An Introduction of Our Technology
Final inspection and acceptance of polished materials must be made at Tripex Manufacturing's factory.
Tripex Manufacturing will work with you, your design and engineering teams to help find the manufacturing process that is right for the dimensional and budgetary constraints of your project.
In general, the cost of manufacturers increases as the allowable tolerance becomes smaller. Because a computer drafting package can dimension the parts to thousands of an inch, don't show the dimensions any finer than your application requires. Cutting a part to a +/- 1/8" tolerance is much less costly than cutting it to +/- 0.015"
(Color match on anodized parts) - The color of the anodize changes as the composition of the aluminum changes. This is most problematic at welded joints where the weld filler material is usually a significantly different alloy that the base material. The result is that the weld is generally a darker gray after clear anodizing than the adjacent material. The problem is minimized by filler wire selection and joint design, but cannot be completely eliminated.
Parts processed with CNC cutting systems may have dimensional variations as a result of the mechanical components on the particular system, the cutting process and the material being cut. The robotics of the particular cutting system has both repeatability and location tolerances. The cutting process may not cut truly perpendicular to the surface of the plate. The speed and direction of the cut also influences the kerf width. The material may move on the table as the part heats up from the cutting process causing dimensional deviations. Tolerances for laser cut parts vary by material type, part size and cutting parameters. In general most parts can be held within +/- 0.015”. Please, inquire about special fabrication tolerance or tolerances on parts with any dimension over 36”.
(Crazing in pre-anodized sheets) - Parts made from pre-anodized sheet, have minor cracks in the anodized coating that form when the sheet is formed. This cannot be eliminated.
To ensure product reliability and safety, welding may need to be qualified to certain industry standards. Different products have different design and performance requirements. Because Tripex Manufacturing may not be aware of the specific industry standards for your parts, you, the customer, need to specify those requirements. Tripex Manufacturing will be happy to work with you to be certain that any welding we perform for you meets your requirements. Tripex Manufacturing maintains a wide variety of qualified welding procedures and has the capability to qualify to most welding codes. Please inquire about our welding processes or your special requirements.
