Faspro Technologies is a leader in custom metal fabrication, a value added process that involves the construction of products from various raw material including sheet stock. For us, custom metal fabrication means we build to your engineering drawings or fully develop the product on your behalf. Specialties like sheet metal fabrication using various methods including chemical etching can reduce time to market and improve product quality.
The added benefit of single sourcing development, prototyping and short run production reduces the need for purchasing staff to interact with multiple vendors and eliminates the issues present with shipping parts between vendors for processing.
After verifying the information on the engineering drawings, various metal fabrication processes are used to make the custom parts and apply some type of secondary operation like coating, painting, or assembly.
Photochemical milling is one of the manufacturing processes used in custom metal fabrication. Corrosive etchant is used to remove sheet metal where it touches the raw material. The raw sheet metal is protected from the etchant in areas that represent the final part. After processing, the metal is cleaned with a neutralizing agent and the parts may be separated or sent to another station for further processing.
Laser Cutting is a metal fabrication process that allows for fast and highly accurate feature placement and shape in sheet metal parts. This process is ideal for both prototype development and short run production because it is low cost and very repeatable.
When metal parts require a 3-dimensional shape, forming and drawing are the processes used to achieve high quality, low cost and fast turnaround. Factors that affect the performance of a die include metal thickness and draw depth. Faspro Technologies has years of experience in forming sheet metal parts and can guide the design of these critical part features.
After a part has been created, it sometimes needs to be electroplated and then assembled to other parts. Special techniques are required before and after these steps to ensure the parts meet the specifications on the drawing. Processes like deburring are used to remove sharp edges and polish the parts. Assembly through the use of brazing, soldering, welding or heat staking join two or more parts in a fixed assembly. In some cases, the assembled parts need to move relative to each other and manual assembly with pins, screws, springs, contacts and other components is required. Finally, the assembled parts may need to be kitted as a way to assist final production of a larger assembly. The parts and all fasteners or other attachment parts are contained in a kit, contents are verified and the kit is delivered to the final assembly location.
