Concurrent Engineering
We use concurrent engineering and get involved at the design phase to assure a very good quality and productivity benefit to the customer for the life of the program.LANGOZ can provide dedicated personnel from the design phase through launch to ensure program success by:
Assisting customer's product designers.
Resolving castability issues (machining stock for long-term customer,ejector pin design,cored hole design, draft angle,etc.)
Providing product interface between the customer,LANGOZ,and tooling vendors.

Process Failure Mode & Effects Analysis (PFMEA)
LANGOZ utilizes PFMEA,a structured procedure for identifying and eliminating process related failure modes.
A-sorting Technology
Die Casting is a very complex manufacturing process with literally hundreds of parameters that can possibly affect the quality of castings made.At LANGOZ,process engineers carefully select die-casting machine parameters such as pressures,temperatures and velocities.These parameters are then transferred to dedicated computers hooked up to each die-cast machine.Special software named LANGOZ Die-Cast Monitor (LDM) is installed on each of theirs computers to monitor parameters and compare them to preset low-high alarm settings.If a part produced is out of alarm settings,the part is automatically dumped into the underground scrap conveyer.Process engineers also use computer generated reports to understand the pattern of the die-cast machine parameters and make quick adjustments whenever required.
Quality Assurance Structure

*Computer generated SPC from CMM data
.Die Cast
*X-Ray and Machining audit check for porosity
*In-Process check
.Look - Advise - Segregate - Take Action
*Layered audit
Die Maintenance
LANGOZ offers a strong “on site” preventive die maintnce teahat responds quickly to any situation (24 hour/day). We implement thorough and persistent shot preventive maintenance on all die castings.
