International Etching, Inc. HOME COMPANY PROCESS INDUSTRIAL DECORATIVE CONTACT US Home Precision Parts for Precise Requirements International Etching, Inc. (IEI) manufactures custom metal components and finished metal products through the process of chemical milling on metals, also known as photo-etching. Since 1982, we have been manufacturing at our facility in Providence , Rhode Island , USA , and we continue to do so today. Long recognized for our design expertise and our attention to detail, we have an understanding of what it takes to react to our customer’s needs, with support of short runs and quick turnarounds from tooling to manufacturing. We have the talent, technology, equipment, and techniques to support you in your metal needs for Brass, Bronze, Copper, Nickel, Stainless, and Sterling Silver in thicknesses from .004” – .250”. (Some thicker metals are suitable for surface etching only, while thinner metals are more suitable for piercing and surface etching.) We strive to excel at everything we do. We would like to have the opportunity to work for you. Thank you for visiting our website.

International Etching, Inc. HOME COMPANY PROCESS INDUSTRIAL DECORATIVE CONTACT US Capabilities and Tolerances What are our tooling capabilities? Generation of precision photo-tooling requires customer supplied dimensions via sketches or drawings. Data is transferred to high resolution films, stepped and repeated to exact multiple images, and where it then becomes a permanent, non-wearing photographic tool. Modern digital photography can utilize customer-supplied PC/MAC-based programs as well as all Autocad versions and DXF and GBR files. Standard tool production time is 2-3 days but can be several hours if necessary in a must-have situation. What dimensions and tolerances are possible? A general guideline for tolerance is +/- 10% of metal thickness. This guideline, however, does not express the ultimate capabilities of the photo-chemical machining process since variable etch factors and reduced sheet size can enhance dimensional control. Normally the diameter of a hole or width of a slot needs to be equal to or exceed the metal thickness. Added serifs can achieve any desired corner geometry. Center to center locations are a function of the photo-tooling and are extremely accurate. Since many parts can be stepped and repeated per square foot matrix size, repeatability of shape is consistent and no tool wear guarantees uniformity.
