The HPDC Casting Floor

KastMfg operates 23 die casting machines across two shifts, six days per week.

Cold-chamber machines (aluminum and magnesium):

• 160T, 250T, 400T, 630T, 800T, 1,000T, 1,600T
• All machines equipped with shot monitoring (velocity, pressure, temperature logged every shot)
• Dedicated VADC (vacuum-assisted) machines for T6 and pressure-tight programs
• Robot ladle systems on machines 400T and above
• Robot die spray systems on all machines

Hot-chamber machines (zinc):

• 80T, 160T, 250T, 400T
• Dedicated machines per alloy (Zamak 3, Zamak 5) -no cross-contamination
• SF6/CO2gas protection on magnesium cells
• Automated trim presses adjacent to casting machines on high-volume programs

Melt furnaces:

• Separate holding furnaces per alloy
• Rotary degassing (nitrogen/argon) standard on all aluminum melts
• OES spectrometer chemistry verification on every melt before production

In-House Tooling Shop

KastMfg designs and fabricates all production and prototype tooling in-house. No subcontracting.

The 4,500 m² tool shop houses:

• 8 CNC vertical machining centers (VMC), up to 1,200 x 800 mm table
• 3 CNC EDM (spark erosion) machines -complex cavity and core geometry
• 2 CNC wire EDM machines -precision insert cutting in hardened H13 steel
• 2 deep-hole drilling machines -cooling channels to 1,500 mm depth
• 2 CNC lathes -ejector pins, cores, round components
• 2 surface grinders -parting face flatness to 0.005 mm
• Dedicated CMM for die component verification before assembly
• CAD/CAM workstations: UG (NX), SolidWorks, Moldflow simulation

Every new production die undergoes mold flow simulation before steel is cut. Tooling design reviews (3D model) are submitted to customers for approval before machining begins.

CNC Machining Center

KastMfg's 5,200 m² machining center provides complete post-casting machining without part ever leaving the facility.

• 12 three-axis vertical machining centers (VMC)
• 4 four-axis machining centers with rotary table
• 2 five-axis simultaneous machining centers
• 4 horizontal machining centers (HMC) for gearbox and motor housing bearing bore programs
• Dedicated boring machines for bearing bores to H6 tolerance
• CNC lathes for shaft bore turning and thread cutting
• Robotic deburring station for high-volume programs

Machining capacity: approximately 250,000 machining operations per month across all machines, two-shift operation.
