Over 30 years of plating expertise goes into every Teikuro chrome plated barrel. Control of the plating process is the hall­mark of a quality plating job and the reason Teikuro uses the phrase “engineered surface treatment.” Teikuro plates barrels to the current AMS2460 standard. Systematic monitoring and evaluation of the various aspects of the gun barrel production insures standards of quality are achieved within our process.  Air gauging with computer interface, bore scopes, and testing per the AMS2460 are all integral parts of our quality management process. Proprietary Teikuro electro-polish process is available when required.

 

 

Testing performed per the AMS standard:

Thickness—test method per ASTM B-499;AMS 2460, 3.4.1.

Adhesion—in accordance with AMS 2460, 3.4.2

Hardness—in accordance with ASTM E-384; AMS 3.4.3

Porosity—in accordance with AMS 2460, 3.4.4

Hydrogen embrittlement relief test—is completed in accordance with AMS 2460, 3.4.5; samples per ASTM F 519 Type 1a.1. Mechanical testing is done as well in compliance with AMS 2460, 4.5.5.

The forging industry is a harsh environment related to the stamping industry. For years the industry has had to rely on alternative surface enhancements to provide some form of longevity or simply resurface the forging die with the added time for these processes exceeding several weeks to perform. With the introduction of hard chrome coating to help relieve some of these constraints with a quick turn around.  Some of our customers have told us that the cost is one- third of alternative coatings.  Hard chrome provides exceptional benefits to the industry. It has increased production output along with reducing costly preventive measures to keep tools in service much longer. The hard chrome coating can be reprocessed multiple times with little die preparation.
