Edit Content

Heat treatment processes are applied to metal parts to enhance material properties. These processes include heat treatment, annealing, and other thermal treatments. The specific treatment required should be detailed in the ‘Notes’ section or included in an attached drawing. Standards followed include ASTM B917 for aluminum alloys and AMS-H-6875 or AMS 2759 for steels.

Edit Content

A transparent coating designed to enhance corrosion resistance in 200 and 300 series steels, as well as precipitation-hardened corrosion-resistant steels, by eliminating free iron from the surface. The coating is extremely thin, measuring approximately 0.0000001”, and complies with standards such as ASTM A967, AMS-QQ-P-35, MIL-STD-171, ASTM A380, or AMS 2700.

Electroless nickel plating delivers a consistent nickel coating that protects against corrosion, oxidation, and wear on irregular surfaces. The coated part will have a brighter appearance. The coating thickness begins at 0.0001” and meets ASTM-B733, TYPE IV, SC1, CLASS 1 (default), or AMS-2404 (formerly AMS-C-26074/MIL-C-26074) if specified. For other nickel plating options, please choose “Other” as the finish option and request a custom quote.

Silver electroplating offers excellent corrosion resistance, although it is prone to tarnishing. Silver provides high solderability and electrical conductivity, giving the part a silver-like appearance. The coating thickness typically ranges from 0.00002” to 0.0003” and complies with AMS QQ-S-365D standards.

Zinc plating is a metal coating applied to conductive materials to enhance corrosion resistance. It is commonly used on carbon steels and other alloys prone to rust. Zinc plating meets the ASTM B633-15 service class I (SC1) specification. The typical coating thickness is 0.0002”, and the finish provides a subtle silver shine.

Injection Molding Finishes In Detail

Edit Content

SPI A finishes are high-quality surface finishes commonly used in injection molding. These finishes provide a smooth, glossy surface ideal for cosmetic parts and products that require a high level of detail and appearance. They are typically achieved through polishing and fine-texturing techniques, offering a visually appealing, mirror-like finish with minimal visible defects. SPI A finishes are often used in industries such as automotive, consumer electronics, and medical devices for premium products.

Edit Content

SPI B finishes are slightly less refined than SPI A finishes but still offer a smooth, consistent surface. They are commonly used for parts that require a good aesthetic appearance without the need for a high-gloss, mirror-like finish. Achieved through moderate polishing and texturing techniques, SPI B finishes typically have a satin or semi-gloss surface, with slight visible texture or imperfections. These finishes are suitable for applications in industries such as automotive, appliances, and consumer goods, where a balance of quality and cost-efficiency is required.

Edit Content

SPI C finishes are characterized by a more textured and matte surface compared to SPI A and B finishes. These finishes are commonly used for parts where a smooth appearance is less critical, and a more functional or rugged look is desired. Achieved through light polishing and coarser texturing techniques, SPI C finishes show visible texture and are often used for applications in industries such as automotive, industrial products, and electronics, where durability and cost-effectiveness take precedence over aesthetic detail.

Edit Content

SPI D finishes are the most textured and roughest among the SPI classifications. These finishes are typically used for parts where aesthetics are not a priority, and functionality and durability are the main focus. Achieved through minimal polishing and coarser surface treatment techniques, SPI D finishes provide a more pronounced texture, often with visible marks or imperfections. They are commonly used in industrial and heavy-duty applications where the part’s performance, strength, and cost-efficiency are prioritized over appearance.
