? ?Aluminum Alloy ASTM A356 , 319 , 359 , 357,308 ,380 etc
Methods
Castings are made using the most appropriate casting methods based on the material and physical form of the part. Some of our current casting methods are:
??? Green sand casting
???Resin sand casting
???Lost-wax casting method(water-glass and silica sol).
???Low pressure Casting ,
???Gravity casting ,
???Permanent mould casting ,
???Investment casting
???Vacuum molding system
???Die casting
Machining
Castings are machined using fixtures and jigs to assure accuracy and repeatability. We have a large variety of machines
available to meet most needs including:
? ?CNC Machining Centers
? ? CNC Lathes
? ?CNC Milling Machines
? ?Manual Lathes, Milling Machine, Planner, Grinder, Drilling Machines
? ?Vertical Boring lathes
Heat-treatment
Annealing, normalizing, tempering, quenching can be applied according to customer’s requirements.
Finishing
Castings can be primer coated, powder-coated, epoxy coated, galvanized, dacrometed, passivated on as-cast surfaces
and a corrosion inhibitor on the machined surfaces.
Patterns
Patterns are manufactured at specialized pattern shops out of aluminum to insure molding quality and repeatability.
Inspection
Parts are inspected prior to shipping by on site inspectors utilizing standard testing and inspection methods.
? ?Chemical Analysis
? ?Mechanical Testing
? ?Hydrostatic Pressure Testing
? ? Magnetic Particle Inspection
? ?Ultrasonic Inspection
? ?Special testing can also be conducted with external test center’s assistance based on customer’s requirements.
