Iosso Metal Processes functional chrome plating offers longer life, corrosion resistance, lubricity, and increased surface hardness, with unsurpassed uniformity.
This thin dense chrome has critically controlled tolerances therefore eliminating costly secondary operations. The coating penetrates the surface eliminating any chance of cracking, peeling or flaking off.
Iosso Metal Processes services a wide spectrum of industries which include the medical industry, automotive, aerospace, food industry, lock components, packaging equipment, hydraulics, and plastic injection molding.
The Iosso-FE process is a proprietary coating for the surface treatment of metal alloys. The process is a method that is bonded directly onto the surface to provide a hardened outer case. It is an electrochemical process that can be controlled to provide critical mechanical tolerances with superior uniformity. The hardness factor achieved is based on the alloy. The Iosso-FE process achieves RC factors of up to 72 RC. The surface thickness to achieve superior surface hardness is a controlled tolerance from .000020 to .0005 of an inch. The surface finish will replicate the existing surface condition. Each part to be processed is individually racked for concise process control, and each customer project is assigned a control number for each specific part processed. When writing specifications, the customer references the control number, which is the Quality Control reference, which indicates the actual process conditions and process time per part.
The contents and chemical composition are proprietary. The composition is comprised of 99 percent pure chromium, which is run at ambient temperature. There is no residue left behind that could flake, peel, or crack. In all of their coating processes, the underlayment of a base material is not needed. Through this process, Iosso can control the coating and achieve superior adhesion and coverage. Due to the tool design and the prescribed process run, they can achieve the quality and life expectancy that is needed. Capabilities include all types of component wear parts, packaging equipment parts, molds and mold components, fluid handling parts, lock parts, gears, cutting blades, and die-cutting components for extended life. The major benefit of the Iosso-FE process is that they do not have to alter the surface of any part prior to plating, nor do they acid etch any components to achieve adhesion. The Iosso-FE process works due to the intense design and controls put into place. The plating process is Rohs Compliant and meets the requirements for Packaging Clearing House.
Iosso-ZN Process
The Iosso-ZN process is a thin dense chrome plated onto zinc base metal. Production and precision-type wear parts can now be made utilizing zinc alloys hardened with the Iosso-ZN Process; this combination makes zinc a viable competitor to steel, aluminum, and plastics. Applications span the full range of industries from agricultural to nuclear energy. Included are aerospace, automotive, communications, computers, electronics, food processing, medical equipment, munitions, textiles, and virtually any industry that has a wear, abrasion, and or corrosive environment.
The Iosso-ZN process transforms every day zinc alloy parts into tough, hard, extremely wear-resistant materials. The process bonds directly with the zinc alloy surfaces to provide a hard outer case, not simply a surface-deposited coating. A new, diffused surface is the result—which is extremely hard and tough — providing manufacturers with a new concept for wear management implementation.
The Iosso Metal Processes can be applied to most alloys; however, Iosso-ZN-treated zinc-based materials carry two significant advantages:
- A uniform hardened surface.
- Precision, economical part manufacturing.
The Iosso-ZN process is controlled to provide critical mechanical tolerances of superior uniformity, which is far superior to conventional copper, nickel, and chrome plating techniques, nitrate dips, and oxide coatings. Controlled hardness of the surface up to 72 RC. The provided Iosso Hard Metal surfaces are uniform over complex edges with no edge build-up. Bonding directly with the base metal means that there is no peeling, flaking, or spalling of the hardened surface.
The extremely hard, tough surface is ideal for abrasion resistance in wear-related applications. A very low coefficient of friction provides a self-lubricating quality to the surface for reduced friction and anti-galling applications. The surface is also non-magnetic, static-free, and non-conductive, and the luster exhibited is an attractive silver-like appearance.
Die-Casting
Zinc die-casting is a precision method of producing strong (42,000-47,000 PS| tensile strength), close tolerance, and high-volume components. Zinc has unmatched die castability with the potential to manufacture miniature precision gears, weighing fractions of an ounce, up to the larger, more complex wear-related parts found in various finished products. Zinc die-casting is probably the fastest, most convenient one-step manufacturing process for producing complicated metal parts. Precision, close tolerance casting eliminates most machining operations.
In many instances, expensive brass, iron, and specialty steel castings or forgings are used or require treatments for wear resistance. Now, the IOSSO-Zn processes put conventional zinc die castings into contention to replace many of these previously used alloys. Without sacrificing wear resistance quality, designers can now incorporate precision die-casting technology to produce more economical components with good strength and close dimensional tolerances that require either no or minimal machining.
