What to confirm before ordering

Each treatment in the list above is a line item, not a separate dedicated page. Powder coating, anodizing and electroplating are covered here as treatments, and the treatment that suits your part depends on material, use and appearance. Before ordering, confirm minimum order quantity and lead time for your drawings.

Drawing checklist

Send the drawing with units and scale stated, the material and grade, the critical dimensions and tolerances marked, and the finish required. State the quantity you need checked and the question the part must answer: fit, function or appearance. Uploaded files are used only for the quotation, and non-disclosure agreements are supported.

Quality checks

Parts are inspected with a coordinate measuring machine, a projector and height gauges, with quality control at each production stage, and a dimension report can be provided for a project on request.
